The technique involves trial insertion of restorations at the precrystallized stage, allowing verification of the marginal fit and evaluation of the internal adaptation and overall esthetic plan to ensure an optimal clinical result for the definitive restorations. Furthermore, this procedure allows most adjustments to the lithium disilicate ceramic to be made before crystallization and minimizes potential surface and subsurface damage to the definitive restorations.

Many authors have attempted unsuccessfully to elucidate the mechanism behind this drug-induced malady, leaving dentists with unclear guidelines on how to treat these patients. Recent literature suggests a threshold-related impairment of epithelial cell migration over bone. A conservative, non-invasive approach aimed at preserving the epithelial attachment in a patient on a long-term oral alendronate protocol is described. The advantage of this approach is to prevent a highly destructive bone degenerative process that does not have a clear and predictable treatment protocol.

Purpose: The purpose of the study was to analyze the color of the cervical portion of single metal ceramic crowns fabricated with different metal framework designs. Material and methods: The color, as measured on the CIELAB color scale, of 3 different groups of restorations (n=10) fabricated with a high noble metal alloy (V-Deltaloy) and feldspathic porcelain (Noritake Super Porcelain) was analyzed with a colorimeter. Conventional metal ceramic crowns with metal facial margins were compared to metal ceramic crowns with porcelain facial margins and a horizontal reduction of the metal framework (1.0 mm re...

In these situations, the clinician should find a practical way to overcome the lack of resistance of the compromised tooth preparation. Purpose: The purpose of this study was to evaluate the effect of different auxiliary features on the resistance form of crowns with reduced axial wall height and increased total occlusal convergence. Material and methods: An Ivorine tooth was prepared on a milling machine with 22 degrees of total occlusal convergence (TOC), 3.0 mm of occlusocervical height, and a chamfer finish line (Group Ctrl). The crown preparation was subsequently modified to include proximal grooves (Group Grv), and reduced TOC from 22 to 4 degrees in...

For implants with turned surfaces, there was a tendency for implants in the maxilla to fail more frequently compared to the mandible. Implants with turned surfaces had a higher likelihood of failure in the posterior region than in the anterior region. For implants with roughened surface there was no significant association between implant survival and location of the implant, type of bone, or length or diameter of the implant.

The lateral approach to sinus elevation is a successful procedure, with percentages of success close to 100%. Unfortunately, a frequent complication encountered during sinus elevation procedure is perforation of the Schneiderian membrane. In this clinical report, the authors present the application of a diamond coated sonic tip and an air-driven sonic instrument, commonly used in prosthodontics for the preparation of the lateral window osteotomy during sinus augmentation procedures.

At the same time, academic authorities are exhorting clinicians to practice “evidence-based dentistry” and to base their treatment recommendations on sound science. The 2 approaches, unfortunately, are not completely compatible. At the time of writing it is unclear how much evidence is essential over what time period to declare that a given material, procedure or technique is evidence-based. This is difficult to answer, and the answer may be different for different materials, procedures, or techniques. The typical hierarchy of evidence-based treatment with sy...

Sometimes, clinicians are faced with situations where teeth have to be connected with implants even though long-term prognosis of those connections may be questionable. This clinical report presents a connection of 2 implants with 1 tooth in the esthetic zone with a nonrigid connection. Two zirconia custom abutments and 1 zirconia coping definitively cemented on the tooth were used. A zirconia superstructure, veneered with porcelain, was cemented with provisional cement on the abutments and the coping.

Most reports of maxillary overdenture patients have described the use of a bar to splint malaligned implants, followed by successful fabrication of the prosthesis. Few reports have discussed the use of individual abutments in such situations. This clinical report describes the successful use of spherical/ball abutments for the management of 4 malaligned implants in the edentulous maxilla for an overdenture. The rationale and technique for the use of spherical abutments for overdenture fabrication in such situations are described.

One factor which may influence the accuracy of the definitive prosthesis is the stability of the impression coping in polymerized impression material. In some circumstances, an implant must be placed well below the gingival margin, meaning that most of the impression coping will also be situated subgingivally with no contact with the impression material. This can result in reduced stability of the impression coping, allowing it to rotate when fastening the implant analog. The use of longer impression copings to increase the surface area has been suggested to overcome this problem; however, only a few implant systems offer this solution. (Source: Jo...

The semiconvex multiple pontic design described in this article, with its mucosal contact exerted with moderate pressure, is proposed to circumvent the problems encountered with the plaque accumulation, maintenance conditions, phonetics, and compromised esthetics frequently encountered in these patients. The use of a screw-retained, implant-supported restoration is also emphasized to allow for sufficient tissue contact during placement of the prosthesis and for prosthesis retrievability for maintenance or technical reasons.

Material and Methods: An acrylic resin maxillary first molar was prepared with shoulder (buccal), chamfer (palatal), and knife edge (proximal) margin configurations. Forty crowns were produced and then divided into 2 groups according to the manufacturing method (casting method or CAD/CAM technique) (n=20). Each crown was luted to the original stone die with zinc phosphate cement. The margin of the crown, center point of the axial wall, and occlusal area were measured with a 3-dimensional measuring microscope. An independent t-test (internal gap) and repeated measures 2-way ANOVA (marginal gap) were used for statistical analysis (α=.05). ...

Clinical color reproduction poses a challenge because of color interaction with the underlying substrate, whether tooth structure or esthetic restorative material. Purpose: The purpose of this in vitro investigation was to measure the effect of color change resulting from applying 2 shades of ceramic material, translucent (T1) and opaque (O2), to 2 shades of composite resin substrate material, light (A3) and dark (C4), on the overall color of ceramic laminates.

The primary factors causing PTM are periodontitis and occlusal trauma. Comprehensive treatment for managing a moderate degree of PTM, including periodontal, orthodontic and prosthodontic treatment is described. Increasing the occlusal vertical dimension (OVD) with provisional restorations was attempted to create space for retracting maxillary flared teeth. Retraction and intrusion of maxillary flared incisors were achieved by a sectional orthodontic appliance. Splinted crowns from maxillary right lateral incisor to left lateral incisor were fabricated and connected to posterior prostheses by means of attachments to prevent relapse and to provide long-term sta...

Ultrasonic instrumentation has been widely used as a more conservative approach than other methods of removing posts without untoward sequelae. However, copious irrigation must be used to prevent elevated temperatures caused by ultrasonic energy. This clinical report presents the consequences of post removal in 2 maxillary incisors with ultrasonic instrumentation without sufficient regard to root overheating. Necrosis of the surrounding tissues was observed after 2 weeks. The functional and esthetic reconstruction of the area affected by the heat trauma is described.

Using the most retentive components, the Locator Extended Range attachment allows greater rotation than does the ERA for both single and double attachments. Using the least retentive components, the ORS attachment allows the most rotation and ERA the least for both single and double attachments. Using the most retentive components, one attachment allows greater rotation than does 2 attachments for the attachment systems evaluated.

These instruments are used not only for the preparation of natural teeth, but also for the removal of existing cemented fixed dental prosthesis (FDPs). Clinicians use rotary cutting instruments with high-speed handpieces to section existing cemented metal ceramic or ceramic FDPs by creating slots on the facial, incisal, and/or occlusal surfaces of the restorations until the cement is exposed. The restorations can then be removed from the mouth with minimal force on the abutment teeth. These demanding clinical procedures might negatively affect the performance and longevity of rotary cutting instruments and handpieces. Some may even encounter unexpected clinical problems such as fractured rotar...

The correct placement and angulation of dental implants are necessary for the functional and esthetic success of the prosthesis. Often, the restorative dentist will complete a diagnostic waxing to determine implant placement. This information, along with radiographs and the clinical examination, aids the restorative dentist in determining implant angulation, cementoenamel junction (CEJ) position, and the mesiodistal and buccolingual position of the implant. This information is transferred to the surgeon via a surgical template, eliminating guesswork at the time of surgery.

Non-metal RPD frameworks are a common treatment type and rarely include rests. These data indicate a changing partially edentulous patient population and a variable commitment to standard levels of prosthodontic care.

Purpose: The purpose of this study was to analyze the color alterations of different types of metal ceramic alloys during several stages of metal surface preparation and to determine the effect of those changes on the resulting color of opaque porcelain (OP). Material and Methods: Seven different types of alloys (3 base metal, 3 noble, and 1 high noble) were used to prepare disk-shaped specimens (1 mm × 10 mm, n=3), followed by OP application (0.1 mm). L*a*b* values of specimens were recorded after different stages of metal surface preparation (ingot, after casting, after oxidation, and...
