This case‐control study tested the hypothesis that biomarkers within temporomandibular muscle and joint disorders (TMJD) subjects’ masseter muscles or temporomandibular joint (TMJ) synovial fluid correlate with plasma biomarker concentrations. Fifty subjects were recruited and categorized into TMJD cases (n = 23) and pain‐free controls (n = 27) at the University of Minnesota School of Dentistry. Prior to specimen collection, pain intensity and pressure pain threshold masseter muscles and the TMJs were assessed. We collected venous blood; biopsied masseter muscle; and sampled TMJ synovial fluid on the subjects’ side of maximum pain intensity. We assayed these tissues for the presence o...

Face and content validity of the Portuguese version were performed. To assess reproducibility of the data gathered with MFIQ, it was applied to 62 individuals who completed the questionnaire on two occasions. Validity and reliability of the data gathered with MFIQ were evaluated in a sample of 249 patients. Construct‐related validity was assessed through factorial validity (by means of a confirmatory factor analysis), and convergent and discriminant validities were assessed, respectively, by the average variance extracted (AVE), composite reliability (CC) and bivariate correlations between factors. The internal consistency was estim...

Additionally, the self‐perceived overall satisfaction of the dental replacements and the effect on speech was questioned. Objective (acoustic analysis) as well as subjective assessment techniques (perceptual evaluation) were used. The satisfaction of single‐tooth implant group was very high (100%) followed by a satisfaction of 87% for the fixed implant prosthesis group and 68% for the removable prosthesis group. The results of the phonetic analyses revealed a normal intelligibility and oromyofunctional behaviour in the three groups of dental replacemen...

Twenty‐one chewing samples (Optosil) comminuted by healthy dentate adults were analysed with a sieving and scanning method. Scanning was performed using a conventional flatbed scanner (1200 dpi). All scanned images underwent image analysis (ImageJ), which yielded descriptive parameters such as area, best‐fitting ellipse for each particle. Of the 2D‐image, a volume was estimated for each particle, which was converted into a weight. To receive a discrete distribution of particle sizes comparable to sieving, five chewing samples were used to calculate a size‐dependent area‐volume‐conversion factor. The sieving ...

Concerns about these products have stimulated numerous investigations into marking reproducibility, accuracy and interpretation, but none have looked at their effects on the occlusion itself. The aim of this study was to assess whether these products alter the occlusion that they purport to measure by determining whether there are differences in the forces and moments experienced by occluding teeth with and without their presence. A matched pair of IPN Portrait 33° molar denture teeth was placed into occlusion with the mandibular tooth supported by a load sensor and the maxillary tooth mounted onto a vertically sliding assembly with a total weight of 15·1N. The three...

Twenty healthy subjects were randomly divided into two groups. One group [THS group (THSG)] performed the tongue‐holding manoeuvre every 5 s for 20 min. The other group (normal swallow group) swallowed without tongue‐holding for the same length of time as a control. Twenty sessions of training were performed for 4 weeks. All participants also had a videofluoroscopic swallowing study for analysing the biomechanical parameters of swallowing (hyolaryngeal movement, posterior pharyngeal wall movement and the pharyngeal constriction ratio). After 4 weeks of training, none of the biomechanical parameters changed in either group. Exercise using THS did not...

Therefore, the characteristics of different connection systems were investigated. Optical microscopic observation and scanning electron microscopy showed different characteristics of two internal systems, namely the Astra Tech and the Replace Select system, and for different materials. The scanning electron microscopic observation showed for the Astra Tech that the implant–abutment interface seemed to be completely sealed for both titanium and zirconium abutments, both horizon...

Subjects were examined by cine‐magnetic resonance imaging in supine position during swallowing water. Two sets of images for 23 edentulous (with/without wearing complete dentures) and one for 23 dentulous patients were obtained. Radiographic outputs representing three consecutive deglutition stages (oral, pharyngeal and oesophageal) were provided to perform measurements. Deglutition time significantly increased when edentulous patients wore their dentures (mean 0·75 s increased to 1·17 s), whereas dentulous patients’ DT was about 0·91 ...

Three teeth missing in left mandibular region was geometrically modelled in clinically simulated situation. Two implants placement as ‘control’, ‘cantilever’, ‘three‐implants’ and ‘offset placements’ were analyzed with geometric analysis. The cantilever received 180–182% load of control, that is, almost same to the result by Rangert (200%). Three implants received 59–65% load of control, that is, almost same to the result by Rangert (67%). Offset arrangement received 59–65% load of control, that is, larger than th...

In 40 healthy subjects (20 women, 20 men; median age = 26·5 years, range = 22–41 years), LCF was recorded in eight directions during the performance of a voluntary pursing‐like lip‐closing task in four measurement sessions. The correlations between the total sum of the forces generated in all eight directions [total LCF (TLCF)] and each directional LCF (DLCF) and those between opposing DLCF were statistically analysed. The TLCF obtained from the highly reproducible measurements acquired in the four different sessions was normally di...

A literature search was performed to establish different aspects of social support. For each of the six aspects found, one item was selected for inclusion in the new questionnaire. The draft version of the questionnaire was field tested. Thereafter, the psychometric properties of the SPQ were assessed in 250 patients with oro‐facial pain. Principal component analysis (n = 250) showed that the SPQ had a one‐factor structure. The test–retest reliability of the SPQ (in a subsample of 54 patients) was fair‐to‐good (R = 0·70; P < 0·000). Convergent validity, as compared with a non‐sp...

Clinical decisions on restoration repair or replacement are usually based upon the weakest point along that margin interface. Physical properties of a restorative material, such as polymerisation shrinkage, water sorption, solubility, elastic modulus and shear strength, all have an effect on stress distribution and can significantly affect margin integrity. This review will focus on two aspects of margin deterioration in the oral environment: the in vitro testing of margin seal using emersion techniques to simulate the oral environment and to predict clinical margin failure and the relationship betwee...

Participants comprised 20 healthy men. The first set of saliva specimens (S1) was collected at immediately after a 20‐min rest to evaluate stress markers. As stress loading, the participants were required to perform arithmetic calculations for 20 min, after which the second set of saliva specimens (S2) was collected. Each participant was then required to chew a piece of tasteless gum for 10 min, after which the third set of saliva specimens (S3) was collected. After a 20‐min rest, the fourth set of saliva specimens (S4) was collected. Weak, habit...

The influence of the level of depression was also addressed. The tinnitus group was comprised of 100 patients with tinnitus, and control group was comprised of 100 individuals without tinnitus. All subjects were evaluated using the research diagnostic criteria for temporomandibular disorders (RDC/TMD) to determine the presence of TMD and depression level. Chi‐square, Spearman Correlation and Mann‐Whitney tests were used in statistical analysis, with a 5% significance level. TMD signs and symptoms were detected in 85% of patients with tinnitus and in 55% of controls (P ≤ 0·001). The severity of pai...

Alteration of the mandibular position is thought to affect oropharyngeal shape, but this relationship remains poorly understood. We therefore studied the relationship between mandibular position and three‐dimensional shape of the oropharynx in the seated posture normal for feeding. Ten healthy, dentate subjects participated (average age, 28·1 years). Experimental mandibular positions were the intercuspal position, bite‐raised position and mandible‐advanced position. The oropharynx was scanned in a 90° seated posture using dental cone‐beam computed tomography, and the effec...

Odontogenic maxillary sinusitis accounts for approximately 10–12% of maxillary sinusitis cases. Proper diagnosis of odontogenic sinusitis is based on a thorough dental and medical examination and crucial to ensure therapeutic efficacy. To establish the odontogenic cause of maxillary sinusitis, 2D and 3D imaging modalities may be considered, each presenting distinct advantages and drawbacks. The available research indicates that 2D imaging modalities may often mask the origin of odontogenic maxillary sinusitis. This limitation is particularly evident in the maxillary molar region, stressing the need for 3D cross‐sectional imaging. The advent of low‐dose cone beam comp...

Accompanying the increase in placement of composite restorations in general practice, there has also been increased evidence that repair, rather than replacement, of composite restorations is being increasingly considered as a treatment option. Previous work has demonstrated that such techniques are often underutilised in practice. The aim of this study was to examine contemporary teaching of composite repair techniques in Scandinavian dental schools. A questionnaire was distributed by email to each of the 12 Scandinavian dental schools in late 2010/early 2011. This questionnaire sought information on the undergraduate teaching...

In addition, this study was designed to verify whether there was a correlation between implant stability quotient (ISQ) values, maximum insertion torque values, angular momentum and energy, and to evaluate the importance of different clinical factors in the determination of ISQ values and maximum insertion torque values at implant insertion. Two different implant designs of 81 dental implants in 41 patients were evaluated using ISQ values. Maximum insertion torque values were obtained during the placement procedure. Two new methods were used to calculate the angular momentum developed due to implant installa...

However, during base of tongue reconstruction the lingual nerve is often severed on one or both sides, affecting sensation in the preserved tissue of the anterior tongue. The loss of specific tongue sensations could negatively affect a person’s oral function and quality of life. The aim of this study was to explore the effects of different types of lingual nerve intervention on sensory function for patients with base of tongue cancer as compared to healthy, age‐matched adults. Subjects included 30 patients who had undergone primary oropharyngeal reconstruction with a radial forearm free‐flap and 30 matched controls. Sensations tested were temperature, two‐...

We investigated whether adult subjects with mandibular prognathism show impaired smoothness of the masticatory jaw movements. Forty‐nine adults with skeletal Class III malocclusions and 52 healthy adults with acceptably good occlusions were selected respectively as Test and Control subjects. Subjects of the Test Group were subdivided into two groups: Class IIIclosed showed full occlusal contact between the upper and lower teeth at the habitual intercuspal position, whereas Class IIIopen showed inability of occlusal contact between the upper and lower anterior teeth.

Most previous reports have been based on a small number of HR patients and have been published before the disease could be confirmed genetically. The aim of the present study was to describe the periapical and endodontic status of permanent teeth in patients with genetically and/or biochemically confirmed HR. The patients were recruited from a medical study on HR patients. The patients underwent a dental examination including a digital panoramic radiograph, which was scored for endodontically affected teeth (i.e. teeth with periapical radiolucencies and/or endodontically treated teeth). A total of 52 patients (age range: 5·7�...

We hypothesised that the propensity to develop severe OSA could be minimised if the dental arches were enlarged in obese OSA people who are thought to have a large tongue. We therefore compared the size of the dental arches in obese and non‐obese OSA patients. Using a lateral cephalogram and study models, we compared the sizes of the tongue and dental arches in 23 obese and 23 non‐obese Japanese male OSA patients, who were matched for age, apnoea hypopnea index (AHI) and maxillomandibular size. The median age (years) and AHI (events per hour) for the obese and non‐obese groups were 36·5 and 39·0, and 13·4 and 14·3, respectively. The...

Consensus meeting of eight experts from various geographic areas representing different perspectives (orofacial pain, headache, oral medicine and ontology) as an initial step towards improving the taxonomy. Ontological principles were introduced, reviewed and applied during the consensus building process. Diagnostic criteria for persistent dento‐alveolar pain disorder (PDAP) were formulated as an example to be used to model the taxonomical structure of all orofacial pain conditions. These criteria have the advantage of being (i) anatomically defined, (ii) in ac...

Here, we extend these studies to determine whether BoNT/A could attenuate IoNC‐induced symptoms of thermal hyperalgesia. Instead of testing head withdrawal thresholds, a thermal operant assay was used to evaluate cortical processing of sensory input following IoNC. In this assay, a fasted rat’s desire to obtain a food reward (sweetened condensed milk) is coupled to its ability to tolerate facial contact with a warm (45 °C) thermode. Bilateral IoNC decreased the ratio of thermode contact duration/event, which is an indicative of thermal hyperalgesia. BoNT/A injection int...

Sixty healthy subjects participated and chewed on red–blue wax for 5, 10, 15 and 20 chewing strokes. The subjects were divided into three groups of 20, matched for age and gender, according to their dental status: natural dentition, full dentures and maxillary denture plus implant‐supported mandibular overdenture. Mixing of the chewed wax was determined by computer analysis of images of the wax and by visual assessment of the images by five examiners. Both the computer method and the observers were able to distinguish the mixing abilities of the dentate subjects from the two denture wearer groups. Computer analysis could also discrimin...

Although many studies have been reported, there are no clear recommendations for the management of SDA cases. In this work, therefore, an innovative system, the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach, was used to grade the evidence and strength of recommendations for clinical intervention. An extensive literature search for longitudinal studies was conducted on 17 November 2010 in the PubMed and LILACS electronic databases using the term shortened dental arch. A ‘snowballing’ strategy, for example, manual searching of the reference lists of included papers, was also conducted. Unpublis...

We selected 2005 individuals by telephone survey and asked them about TMD symptoms like difficulty in jaw movement, jaw pain and joint sounds. Also, tooth‐clenching and/or tooth‐grinding habits were investigated. Of the study population, 8·1% reported limitations in jaw movements, 5·1% reported jaw pain and 33·3% reported joint sounds. Furthermore, 37·3% reported tooth‐clenching/tooth‐grinding. Confidence intervals of proportions were calculated. Significant gender differences were found for jaw limitation and pain (chi‐square test; P < 0·05). Symptoms reduced with increasing age. The pre...

In 20 healthy subjects, the electromyographic response to unilateral and bilateral maximum voluntary tooth clenching, balancing the mandible on a hydrostatic system under force‐feedback‐controlled conditions, and unilateral chewing was investigated in an initial session and then in two follow‐up sessions separated by 2 and 10 weeks from baseline. Motor tasks were repeated three times for chewing, nine times for maximum biting (MB) and 24 times for the coordination tasks (CT). The sequences of the various motor tasks were applied once in the first session and twice in the second and third sessions. No effects of training were observed for MB...

The integrated EMG signal was adopted to quantify the work (μV × s) produced by each of the four muscles (bilateral masseter and temporal) during the 5‐h recording span and per each 1‐h increment. The duration of MMA events and the muscle work during the first hour of sleep was related to trait anxiety scores for both masseter (P = 0·007) and temporalis muscles (P = 0·022). Trait anxiety was also signi...

Sixty partially dentate patients (mean age, 64·1 years) with shortened dental arches participated in the study. Food comminuting ability was assessed using a masticatory performance test with peanuts as a test food. Food mixing ability was assessed using a mixing ability test with a two‐coloured wax cube. Maximum bite force (MBF) was measured using a pressure‐sensitive film as a mediator for food comminuting and mixing ability. A structural equation model was constructed based on a hypothesis that MOUs would be associated with reduced MBF and impairment of food comminuting and mixing ability. Structural...

In a study of 171 consecutive patients with removable partial dentures or complete dentures (mean age: 68·0 ± 9·3 years) at a university‐based prosthodontic clinic, dentists rated two aspects of denture quality (stability and aesthetics) using a 100‐mm visual analog scale (VAS). HRQoL was evaluated using the mental and physical component summary (MCS and PCS) scores of the Medical Outcomes Study Short‐Form 36‐Item Health Survey (SF‐36). Oral health‐related quality of life (OHRQoL) was evaluated using the Oral Health Impact Profile‐Japanese version (OHIP‐J). The associations among denture quality, OHRQoL, and HRQo...

However, while a vast literature is available concerning accuracy of motor control in limbs, quantitative and objective assessment of mandibular motor control has been seldom performed, also because of the lack of adequate investigative tools. Aim of this work is to present a technique for reliable evaluation of the motor performance of the mandible based on a kinesiography‐monitored reach‐and‐hold task. Nineteen healthy subjects were engaged in a task in which they had to drive a cursor on a screen by corresponding movements of the mandible in the frontal plane and reach 30 random targets sequentially displayed on the screen. The whole task was repeated three times per s...

The aim of this study was to investigate whether signs and symptoms of TMD can be identified as risk factors for developing tinnitus. The SHIP 1 is a population‐based 5‐year longitudinal study intended to systematically describe the prevalence of and risk factors for diseases common in the population of Pomerania in northern Germany. A total of 3300 subjects (76% response) were reevaluated after 5 years for tinnitus and signs and symptoms of TMD using the same questionnaires and examination tools as baseline. To estimate the relative risk (RR) appropriately, a modified Poisson regression was us...

Microtensile bond strengths of DMAE‐CB‐incorporated adhesive and its parental adhesive to dentin were compared. Dentin discs bonded with modified adhesive were incubated in artificial saliva at three different temperatures for 90 days to obtain eluents. The cytotoxicity of DMAE‐CB monomer and adhesive eluents were tested with 3‐(4, 5‐Dimethylthiazol‐2‐yl)‐2,5‐diphenyltetrazolium bromide cleavage assay (MTT assay).

The present study tested the hypothesis that raising the bite without mandibular protrusion in OSA patients is associated with an increase in the apnoea–hypopnoea index (AHI). Eighteen OSA patients (13 men; 49·5 ± 8·1 years old) received a mandibular advancement device in 0% protrusion of the mandible (0%MAD). The MAD caused a bite rise of 6 mm as measured interincisally. Polysomnographic recordings were obtained at baseline and with the 0...

This investigation sought to determine whether pain from temporomandibular disorders was associated with increased oxidative stress as measured by biomarkers in saliva and serum. Both salivary and serum levels of the oxidative stress biomarkers including 8‐hydroxydeoxyguanosine, malondialdehyde and total antioxidant status were compared in patients with mild and severe TMJD pain and with healthy controls. These biomarkers were determined spectrophotometrically in saliva and serum from 10 high TMJD pain patients, 10 low TMJD pain patients, and 10 healthy control subjects from Nation...

A randomised, controlled trial was performed in 80 recruited TMD pain patients. They were randomly allocated to one of two groups: treatment with a resilient appliance or treatment with a hard, palatal, non‐occluding appliance. The primary treatment outcome was judged positive when patients’ characteristic pain intensity decreased by at least 30%. Additional treatment outcomes were physical functioning, emotional functioning and headache. At the 12‐month follow‐up 50% of the patients in the treatment group and 42% in the control group had a 30% reduction of characteristic pain intensity, when calculated in an intent‐to‐treat analysi...

The denture system was engineered consisting of a fixed part that is anchored to the posterior palate by orthodontic wires and acrylic resin and a removable part fitted to the anterior palate that is retained by magnets embedded in the fixed part. Both parts are custom fitted to the rodent palate by impression making and cast fabrication. Rats fitted with the intraoral denture system maintained body weight and normal activity with the device maintaining integrity and durability...

Subjects comprised 45 fully dentate adults (23 men, 22 women; mean age, 28·1 years). The gum was chewed for a specified number of chewing strokes (20, 40, 60, 80, 120 or 160 strokes) without any instructions as to chewing side. A colourimeter was used to measure L*, a* and b* values (CIE‐L*a*b* colour system) for the chewed gum, then the difference between two colours in the CIE‐L*a*b* colour space (ΔE) for each number of chewing strokes was calculated according to a formula. Index of masticatory performance (ΔE60) for each subject was obtained using ΔE for 20, 40, 60, 80, 120 and 160 strokes. Mand...

The analysis was performed on the sleep recordings of 8 SB subjects and 8 controls who received sensory stimulations during sleep. Baseline and experimental nights were compared for sleep variables, CAP, and EEG spectral analyses using repeated measure ANOVAs. Overall, no differences in sleep variables and EEG spectra were found between SB subjects and controls. However, SB subjects had higher sleep instability (more phase A3) than controls (P = 0·05). The frequency of phase A3 was higher in the pre‐REM sleep periods (P < 0·001), where peaks in RMMA/SB activity were also observed (P = 0·05). When sleep instability was experim...

The retro/micrognathism can be treated with functional appliances. However, the effects of an early functional orthopedic treatment on the airway dimensions have not been evaluated before the growth peak. Therefore, the objective of this study was to evaluate the changes in the airway dimensions of class II retrognathic children who received treatment with either Klammt or Bionator on a pre‐pubertal stage. The sample consisted of 50 lateral cephalograms of class II retrognathic patients in a pre‐puberal stage, before and after the use of a Klammt or Bionator II treatment for 1 year.

Characteristics of the oral system, like number of teeth, bite force and salivary flow, will influence the masticatory process. Masticatory function of healthy persons has been studied extensively the last decades. These results were used as a comparison for outcomes of various patient groups. In this review, findings from literature on masticatory function for both healthy persons and patient groups are presented. Masticatory function of patients with compromised dentition appeared to be significantly reduced when compared with the function of healthy controls. The influence of oral rehabilitation, e.g. dental restorations, implant tre...

However, few studies evaluated whether a poor oral status without prosthetic rehabilitation is associated with a reduction in the consumption of fruit and vegetables in community‐dwelling older persons. We evaluated the association of oral status with emphasis on complete dentures use with the daily consumption of at least 400 g of fruit and vegetables, following the recommendations of the WHO. A random sample of 282 south Brazilians ≥60 years of age was evaluated. Measurements included a questionnaire to assess sociodemographic, b...

A survey of four commercial dental laboratories located in northern England was conducted. The target of this survey was cobalt chromium RPDs that were requested to restore SDAs comprising the anterior teeth and 2–4 premolars. Dentists’ prescriptions were scrutinised, and a special data collection form was completed accordingly. A total of 94 dentists’ prescriptions and associated SDA casts were examined. Almost all the requested cobalt chromium RPDs were clasp‐retained RPDs (97%). Scrutinising the 91 prescriptions for clasp‐retained cobalt chromium RPDs showed that den...

Thirteen patients clinically diagnosed with tetanus (10 with severe tetanus and three with very severe tetanus) and admitted to an intensive care unit underwent clinical evaluation of oral‐motor movements and speech. Statistical analysis indicated significant between‐group differences for speech motor functions, suggesting that individuals with very severe tetanus present rigidity as a characteristic interfering in articulatory precision (P = 0·035) and movement rate (P = 0·038). For lip closure, tongue movement, palatal elevation, gag reflex and voice quality, no between‐group...

The strength of the anterior portion and of the dorsum of the tongue was analysed with a calibrated electronic dynamometer. The subjects were asked to apply maximum force. Men showed higher tongue strength values than women both in the anterior portion and in the dorsum of the tongue (P < 0·05), and the strength of the anterior portion of the tongue was lower than that of the dorsum in both genders (P < 0·05). We conclude that gender and region influenced tongue strength.

One hundred and nine Irish subjects (age 18–25 inclusive) had irreversible hydrocolloid impressions made of their maxillary dentition poured in type V stone. Clinical crown dimensions were measured with a digital calliper. The stone casts were digitally photographed in a standardised manner enabling calculation of various ratios between the maxillary anterior teeth. Sexual dimorphism existed for various tooth dimensions; most notably canine teeth were in the region of 0·8 mm longer and 0·6 mm wider in males. Central and lateral incisors were found to be 0·5 mm wider in males. It is, therefore, recommended that dimensional tooth guidelines should be gi...

However, increased forces exerted by the overdenture could increase residual ridge resorption of the maxillary anterior and mandibular posterior areas. The aim of this study was to compare the effect of the mandibular implant‐retained overdenture using two or four dental implants, or the conventional complete denture on resorption of the residual ridge of the maxillary anterior and mandibular posterior areas over a period of 10 years. In total, 120 patients, 30 patients treated with an overdenture on two implants (two‐implant group), 30 patients with an overdenture on four implants (four‐implant group) and 60 patients treated with a conventional...

SDA patients with 2–12 missing occlusal units were consecutively enrolled from seven university‐based dental hospitals in Japan. Of the 145 subjects (mean age; 63·4 years), 41% chose no treatment and 59% sought to replace their edentulous spaces with removable partial dentures or implant‐supported fixed partial dentures. Restoration decisions were related to tooth loss patterns. Only 3% of subjects missing just second molar(s) sought to receive prosthetic treatment, while the percentage increased to 58% in subjects who were missing first and second molars and 93% in subjects missing premolar(s). Logistic regression analyses found that young...

The exteroceptive suppression period (ES2) and inhibitory responses were recorded in the surface electromyogram (EMG) of bilateral masseter and temporalis muscles in 16 healthy subjects. Two stimulus durations (1 ms single pulse and 450 ms pulse train) adjusted to a perceived intensity of 7 (distinct painful) on a 0–10 Numerical Rating Scale (NRS) were applied to the following six oro‐facial locations on the right side while the subject was biting at 50% of the maximal voluntary contraction: masseter muscle, temporalis muscle, temporomandibular joint, infraorbi...

The purpose of this literature review is to examine the relationship between oral anticoagulant medication and dental treatment. Electronic and manual searches were conducted for clinical studies in the English literature for the years 1988–2010. The review process provided a total of 110 pertinent literature references, out of which 38 studies dealt with oral anticoagulants and dental treatment. Different treatment strategies relative to dental periprocedural anticoagulation regimens have been identified, and their accompanying thromboembolic and bleeding risks are being presented and discussed. Regarding to what extent a safe and successful dental treatmen...

A total of 64 patients were recruited in a private specialist implant practice. Two different implant systems were evaluated (IPI, Nobel Biocare, Sweden; I‐Plant, Unor, Switzerland). Primary stability, survival rate, gender, location, the type of prosthetic restoration and the tooth status of the opposite jaw were analysed using Kaplan–Meier or Pearson Chi‐Square test. A total of 254 transitional implants were placed, thereof 216 were IPI implants and 38 I‐Plant implants. The overall observation period ranged between 2 and 426 days. The results demonstrated a survival rate of 82·4% for the IPI system and 84·2% for the I�...

Whatever the cause, damage to the inferior alveolar nerve negatively affects the quality of facial sensibility as well as the patient’s ability to translate patterns of altered nerve activity into functionally meaningful motor behaviours. There is no generally accepted, standard method of estimating sensory disturbances in the distribution of the inferior alveolar nerve following injury. Assessment of sensory alterations can be conducted using three types of measures: (i) objective electrophysiological measures of nerve conduction, (ii) sensory testing (stimulus) measures and (iii) patient repor...

The coronal dentin of nine molars were exposed and divided into groups: 5% GD, 6·5% GSE and control. Control samples were etched, bonded with Adper Single Bond Plus and Premise composite. GD and GSE were applied for 1 h prior to bonding procedures. After 24 h, samples were sectioned, and resin‐dentin beams were either kept in distilled water or exposed to collagenase treatment for 24 h. Nano‐indentations were performed at the hybrid layer and underlying dentin. GD and GSE treatmen...

Eleven adult voluntary subjects were enrolled. A lower impression was taken for each subject and two dental casts were obtained from each impression. The study was carried out in a randomised cross‐over fashion. Each subject participated in two experimental sessions (30‐day interval) in which he/she received an injection in the central part of the right masseter muscle consisting of 0·5 mL of either hypertonic or isotonic saline. Each subject was asked to rate pain intensity on a visual analogue scale. Three occlusal bite checks (polyvinylsiloxane) at the maximal intercuspal position were obtained during the experimental session: the first b...

Twenty‐three people with BMR and 21 people without BMR participated as volunteers in this study. Measurements of viscoelastic behaviour were performed using a suction viscoelastic meter on central part of lower labial mucosa. A suction pressure of 300 hPa was applied for 2 s and then released for 2 s, and the time‐dependent changes in the deformation of the mucosa over this 4 s were recorded as a deformation curve. Distensibility, remaining deformation and elastic recovery, which describe viscoelastic behaviour, were calculated by the deformation curve. These parameters wer...

Seventeen edentulous subjects (seven men, 10 women; mean age 60·3 ± 13·0 years) with newly acquired implant‐retained mandibular overdentures and a conventional maxillary denture participated. Maximum bite forces and corresponding electromyographic (EMG) activity from the temporalis and masseter muscles (bilaterally) were recorded under two experimental conditions: (i) Unilateral premolar and molar bites without additional support, and (ii) premolar and molar bites with bite block support on the opposite side. In addition, EMG values alone were recorded during maximum clenching without any transducer between the upper and lower dentures. The level...

was to determine patient satisfaction with either conventional dentures or mandibular 2-implant overdentures in a 'real world' setting. Two hundred and three edentulous patients (mean age 68·8 ± 10·4 years) were recruited at eight centres located in North America, South America and Europe. The patients were provided with new mandibular conventional dentures or implant overdentures supported by two implants and ball attachments. At baseline and at 6 months post-treatment, they rated their satisfaction with their mandibular prostheses on 100-mm visual analogue scale questionnaires. One hundred and two (50·2%) participants had valid baseline and 6-month satisfaction data. Although both groups reported improvements, the implant ov...

An extended workshop was held in April 2009 in which further recommendations were made from an expert panel, using the 2008 symposium material as a base. This paper is a summary of the 2008 symposium proceedings with elaborations based on further developments. Seven studies were conducted between 2001 and 2008, in which the following were investigated: (i) basic properties of Axis II instruments, (ii) reliability and criterion validity of Axis II instruments, (iii) expansion of predictors, (iv) metric equivalence of the depression and non-specific physical symptoms subscales in the RDC/T...
