Prosthetic Rehabilitation of a Congenital Soft Palate Defect
AbstractObturator is derived from the Latin verb obturate which means to close or to shut off. This definition provides an appropriate description of the objective of obturation in patients with palatal defects. The obturator is often helpful in improving the speech of individuals with partial or total velar defects i.e. cleft of soft palate. Soft palate cleft is one of the most common cause of velopharyngeal incompetence, which is the functional inability of the soft palate to effectively seal with the posterior and or lateral pharyngeal walls. In maxillofacial prosthesis the clinician may have the responsibility for rees...

Comprehensive Rehabilitation of Partially Amputated Index Finger with Silicone Prosthesis: A Case Report with 3  years of Follow Up
AbstractThe loss of all or part of a finger following traumatic amputation may have a negative impact on physical and psychological well-being. An esthetic prosthesis can offer psychological, functional, and rehabilitative advantages. One of the major problems associated with somato-prosthetic replacement of partially amputated finger is inadequate retention of the prosthesis. This may stem from the weight of the prosthesis, inadequate tissue support, and/or the particular area of the finger to be replaced. A number of means have been employed to enhance retention. Among the more common are adhesives, adhesive tape, magnet...

Postural Assessment of Students Evaluating the Need of Ergonomic Seat and Magnification in Dentistry
This study recommends the use of an ergonomic seat and magnification system to enhance the visibility and the posture of an operator. The aim of this study is to make a foray into the hazards caused by inappropriate posture of dental students while working. It also aims at creating a cognizance about the related health implications among the dental fraternity at large, and to understand the significance of adopting an ergonomic posture since the beginning of the professional course. In the present study, postures have been assessed by using rapid upper limb assessment (RULA). This method uses diagrams of body postures and ...

Effect of Dietary Simulating Solvents on the Mechanical Properties of Provisional Restorative Materials-An In Vitro Study
AbstractThe purpose of this investigation was to evaluate the mechanical properties of provisional restorative materials after storage in dietary simulating solvents. A total of 120 specimens, 40 specimens each of Luxatemp Star, Revotek LC and DPI Self Cure were prepared. The specimens were divided into four groups with 10 specimens each and stored in dietary simulating solvents for 7  days at 37 °C as follows: Group I—Control, Group II—Artificial saliva, Group III—0.02 N Citric acid and Group IV—Heptane. After 7 days, flexural strength was obtained using universal testing machine at a crosshead speed of 5 mm...

Zirconia Intra Mucosal Inserts as a Retentive Aid for Maxillary Complete Dentures: A Case Report
AbstractComplete dentures fabricated for edentulous patients with resorbed ridges generally have compromised retention and stability. The use of intramucosal inserts in order to aid retention of a maxillary denture has been reported in the past. Zirconia is a tissue compatible biomaterial whose scope and application in dentistry is on the rise. This paper reports the fabrication of zirconia intramucosal inserts and the technique of its incorporation in the maxillary complete denture in order to enhance retention, stability and thereby oral function.

Dental Implant Placement using C-arm CT Real Time Imaging System: A Case Report
AbstractC-arm computed tomography (CT) is a new and innovative imaging technique. In combination with two-dimensional fluoroscopic or radiographic imaging, information provided by three-dimensional C-arm real time imaging can be valuable for therapy planning, guidance and outcome assessment in dental implant placement. This paper reports a case of two dental implant placement using Artis zee C-arm CT system first time in field of implantology. (Source: The Journal of Indian Prosthodontic Society)

Replacement of a Congenitally Missing Maxillary Incisor by Implant Supported Prosthesis
AbstractMaxillary central incisors have the least incidence of congenital absence. When it does happen, the patient may present with over retained deciduous centrals or the contralateral central may have drifted into the available space presenting as generalised anterior spacing with loss of midline. In such cases a multi-disciplinary approach may be required with orthodontic treatment to re-organise the space available in order to rehabilitate the patient with a fixed prosthesis. This case report presents the treatment of a patient with congenitally missing maxillary left central incisor using dental implant with angulate...

“Split Cast Mounting: Review and New Technique”
AbstractFor the fabrication of a prosthesis, the Prosthodontist meticulously performs all the steps. The laboratory technician then make every effort/strives to perform the remaining lab procedures. However when the processed dentures are remounted on the articulator, some changes are seen. These changes may be divided into two categories: Pre-insertion and post-insertion changes, which deal with the physical properties of the materials involved (Parker, J Prosthet Dent 31:335 –342,1974). Split cast mounting is the method of mounting casts on the articulator. It is essentially a maxillary cast constructed in two parts wi...

Craniofacial Prosthetic Reconstruction Using Polymethyl Methacrylate Implant: A Case Report
AbstractLarge cranial defects of complex geometric shapes are challenging to reconstruct. The cranial implants has to be fabricated prior to the cranioplastic surgery. The ideal material for cranial implant has to be inert, light weight, easy to fit and adaptable to the defect, offering the best aesthetic and functional results. Here is a clinical case report of a patient who was operated for osteomyelitis in the parieto-temporal region. The defect was reconstructed with heat cure polymethylmethacrylate (PMMA). Operative closure of the defect was facilitated with ligature titanium wires with minimal prosthesis contouring. ...

A Comparative Evaluation of the Effect of Double Casting Technique Using Functionally Generated Path and Conventional Single Casting with Respect to Functional Articulation, Patient Satisfaction and Chair Side Time, in Single Unit Molar Teeth: An In Vivo Study
This study was conducted to evaluate the benefits of the double casting technique with FGP over the conventional casting technique. Ten patients with root canal treated maxillary molar were selected for the fabrication of metal crown. Two techniques, one involving the conventional fabrication and other using functionally generated path with double casting were used to fabricate the prosthesis. A comparison based on various parameters which was done between the two techniques. The change in the height of castings for the double casting group was less compared to the conventional group and was highly statistically significan...

Comparison of Marginal Gap and Microleakage in Copy-Milled and Cad-Milled Zirconia Copings Bonded Using Light Cure and Chemical Cure Resin Bonding Systems
AbstractThis in vitro study assessed the marginal gap and marginal microleakage in zirconia copings fabricated using two computer aided techniques- CAD milling and Copy milling and cemented to respective tooth preparations using two resin bonding systems, light cure and self-cure resin bonding systems. 32 extracted premolars were prepared to receive zirconia copings fabricated using CAD/CAM and Copy milling techniques. Once the copings were fabricated, the samples were evaluated for marginal fit prior to cementation through microscopic observation. Evaluation of marginal gap was done again after cementation, in order to in...

A Simple Technique to Fabricate Custom Made Occlusal Plane Template
AbstractThe plane of occlusion represents the average curvature of the occlusal surfaces of anterior and posterior teeth rather than a flat surface. An anteroposterior curve, the curve of Spee and the mediolateral curve, the curve of Wilson determine the position of posterior teeth. Management of patients with uneven occlusal plane is an essential step for the long term success of the treatment. Devices, like occlusal plane analyzers, are routinely used to evaluate the occlusal problems and help improve the situation. Yurkstas metal occlusal template is a device frequently used to determine proper occlusal plane. A simple ...
