Loss of occlusal vertical dimension is a frequently observed problem in the middle aged and aged population who intends to retain their natural dentition. This type of patient has very few treatment options one of which is overdenture. In this case report, a patient was treated with overlay removable partial denture for restoring the lost vertical dimension. This was provided as interim prosthesis. The follow up was done to observe the fulfillment of desired results. The clinical and laboratory procedure is described briefly. The treatment used for this case is cost effective and conservative solution for esthetic and functional rehabilitation. Since the material is acrylic resin, long term wear resistance is crucial for success of treatment. The rehabilitation would be fixed prosthesis with newly adjusted vertical dimension.DOI: http://dx.doi.org/10.3329/cdcj.v9i1.11835 City Dental College Journal Vol.9(1) 2012 28-31

BACKGROUND: Retainers are of great importance for the longevity of the prosthetic removable partial denture during various functions especially the esthetic one. The key of successful clasp selection is to select a direct retainer that will control tipping and torquing forces on the abutment teeth, provide retention against reasonable dislodging forces and are compatible with both tooth and tissue contour together with the aesthetic desire of the patient. AIM: This study aims to compare different clasp material to enhance the choice of the clasp based on the aesthetic point of view. METHODS: The colour evaluation of the tested materials had been evaluated by computer aided technique with digital camera with 3 Mega Pixels of resolution. RESULTS: In the current research, the technique of colour evaluation was carried out to compare different clasp materials to enhance the choice of the clasp based on the aesthetic point of view. Most commonly, Removable Partial Denture (RPD) retainers are fabricated identically from the metal framework’s alloy as Cobalt Chromium (CoCr) alloy although it is unaesthetic. This esthetic problem has been overcome by other methods and by utilising different materials, these included covering the retainers with tooth-coloured acrylic resin, as well as the introduction of esthetic materials as; Thermoplastic Acetal, Versacryl, and Thermopress. CONCLUSION: It has been concluded that the non-metallic Acetal resin clasp shows superior physical properties regarding colour stability.

This article reports the case of a 55-year-old female patient who presented with unsatisfactory temporary crowns in the right mandibular premolars and molars, and a premolar-to-molar fixed partial denture in the left side. The clinical and radiographic examinations revealed a fracture of the left first premolar that was a retainer of the fixed partial denture and required extraction. Initially, the acrylic resin crowns were replaced by new ones, and a provisional RPD was made using acrylic resin and orthodontic wire clasps to resolve the problem arising from the loss of the fixed partial denture. Considering the patient's high esthetic demands, the treatment options for the definitive prosthetic treatment were discussed with her and rehabilitation with implant-supported dentures was proposed because the clinical conditions of the residual alveolar ridge were suitable for implant installation, and the patient's general health was excellent. However, the patient did not agree because she knew of a failed case of implant-retained denture in a diabetic individual and was concerned. The patient was fully informed that implant installation was the best indication for her case, but the arguments were not sufficient to change her decision. The treatment possibilities were presented and the patient opted for a clasp-retained removable partial denture (RPD) associated with the placement of crowns in the pillar teeth. The temporary RPD was replaced by the definitive RPD constructed subsequently. Although RPD was not the first choice, satisfactory esthetic and functional outcomes were achieved, overcaming the patient's expectations. This case report illustrates that the dentist must be prepared to deal with situations where, for reasons that cannot be managed, the patient does not accept the treatment considered as the most indicated for his/her case. Alternatives must be proposed and the functional and esthetic requirements must be fulfilled in the best possible manner.

The purpose of this study was to investigate the effects of implant position and loading position on biomechanical behaviors using implant-supported removable partial denture (ISRPD) models in a simulated Kennedy class Ⅱ partially edentulous mandible. Three types of Kennedy class Ⅱ mandibular acrylic resin models (a conventional RPD without support by an implant—CRPD; models with an implant placed at first molar (#46)—MP-ISRPD— and second molar (#47)—DP-ISRPD) were used to measure vertical displacement of the RPD, mesio-distal displacement of the abutment tooth, and bending moment of the abutment tooth and implant under one-point loading. The variables at three respective loading points (#45, #46 and #47) were compared statistically. Vertical displacement was suppressed in ISRPDs compared to the CRPD, and significant effects were identified under loading at the implant position. The largest meiso-distal displacement was observed in MP-ISRPD under #47 loading. Bending moments of the abutment tooth and implant were significantly higher in MP-ISRPD than in DP-ISPRD. In MP-ISRPD, a higher bending moment of the abutment tooth under #45 and #47 loading was detected, although the bending moment in DP-ISRPD was almost zero. The results of this study suggested that MP-ISRPD shows the specific biomechanical behaviors, although DP-ISRPD might provide biomechanical benefits under all one-point loading conditions.

Background: Dental laboratory in Surabaya frequently make various kinds of the denture. But surely there is a case that was the most commonly accepted, to adjust to the needs of dental laboratories on the priorities of the work was done, it was necessary to give attention to the case that many common and must be taught to students Dental Technology. Purpose: To find an overview of the number the dentures received by the dental laboratory in Surabaya from 2013 until 2017. Methods: The data used is secondary data from a dental laboratory in Surabaya from 2013 to 2017. Result: A request for flexible and RPDs porcelain, acrylic resin and metal in 5 years obtained tend to be stable in high demand, even ina given year a sharp increase in RPDs flexible and drastic decline on fixed porcelain denture. Instead of facing acrylics, fixed denture tends to stabilize at its lowest during the period. While the acrylic RPDs has increased significantly in the last two years, in contrast to metal frame dentures, which decreased at two years latest. Conclusion: Flexible denture significantly better than with acrylic resin conventional denture on parameters taken in this research. Fixed porcelain denture are mostly made by a dental laboratory when compared with a removable partial denture acrylic resin.

ABSTRACT Aim This study was carried out with the purpose of comparing three impression methods as to which of them placed tissues most favorably. Methods The methods used were Hindels method, selective tissue placement method and functional reline method. The measurements obtained were analyzed to determine which of the three impression methods placed the mucosal tissues maximally. To compare and measure tissue placements, autopolymerizing acrylic resin platforms were constructed to the height of the occlusal surfaces of the remaining teeth. 15 orthodontic buccal tubes were placed on each side of the platform. They were arranged in three sets of five and attached to the platform over selected reference regions by means of autopolymerizing resin. The selected reference areas were in anterior, middle and posterior areas of the ridge on either side. Results No significant difference was seen in tissue placement in the anterior middle and posterior regions in each of the three methods when each method was assessed separately. Selective tissue placement method placed the tissues maximally (7.547 mm) followed by Hindels method (7.2110 mm) and the least placement was by functional reline method (5.856 mm). Tissue placement was significantly higher in Hindels method as compared to functional reline method (p < 0.001). Conclusion Tissue placement was maximum in the posterior region, followed by the middle region and least in the anterior region of the mandibular ridge for all three methods. Selective tissue placement method showed the maximum overall tissue placement followed by the Hindels method and minimum placement was by functional reline method. Clinical significance Selective tissue placement method provided maximum overall tissue placement and can be a preferred technique for impression making for bilateral distal extension removable partial denture fabrication.
