ABSTRACTFor patients with shortened dental arches, many treatment options are available. The existing situation can be maintained by stabilizing the present dentition and improving the occlusion without extending the arch. Alternatively, the shortened dental arch can be extended by either a free-end saddle removable partial denture, cantilevered fixed bridge, or by an implant-supported prosthesis. The free-end saddle removable partial denture can be considered a simple, non-invasive, and relatively cheap treatment option for the shortened dental arch. It was believed that such prosthodontic rehabilitation would be beneficial for the patients in terms of improving oral functions. However, the existing literature indicates that the prognosis of free-end saddle removable partial denture is not predictable, it is problematic, and its contribution to oral functions in patients with shortened dental arches is considered to be dubious. This paper reviews and summarizes the current literature about the outcome of extending the shortened dental arch by a free-end saddle removable partial denture. It also outlines factors that may affect the prognosis of this prosthetic treatment.

Background: Complete dentition is not always appropriate for old aged medically compromised and financially weak individuals. It is the dentist to decide what minimum number of teeth should be restored to have the proper oral function. The aim was to find out the opinion of prosthodon­tists of Nepal regarding the suitability of shortened dental arch as treatment modality and how frequently is this treatment choice for an old aged Nepalese patient. Methods: A pretested close ended questionnaire was usedin this study.After taking ethical clear­ance from Nepal Health Research Council, online questionnaire was sent to the participants along with the consent. Analysis was done using SPSS (version 21) statistical software package. Descrip­tive statistics was used. Percentage and frequencies were calculated. Results: Among respondents, 96.2% (n=51) had heard about shortened dental arch therapy but 3.8 % (n=2) had never heard about it. Forty-two (79.2%) do support shortened dental arch. Eleven (20.8%) do not favorshortened dental arch. Their main reason for replacing molars was to improve masticatory function.Instead of shortened dental arch,n=5(45.5%) prefer cast partial denture and 6(54.5%) advice implant supported fixed prosthesis. Among Prosthodontists who recommended shortened dental arch therapy, eight (19.1%) always advised patients not to replace molars. Twen­ty-four (57.1%) prosthodontists who support shortened dental arch therapy mentioned chewing function in shortened dental arch patients as satisfactory. Conclusions: Majority of Prosthodontists agree that shortened dental arch is a suitable treatment option for older people in developing countries like Nepal. But the treatment is not employed in clinical practice as required.

PURPOSE: The aim of this study was to evaluate biting force of patients with unilateral mandibular distal extension area treated with two different designs of the removable partial denture (RPD), conventional RPD, and new design of extracoronal castable precision attachment (OT Unilateral attachment). MATERIALS AND METHODS: This study was conducted on 16 patients with unilateral mandibular distal extension area with the second premolar is the last abutment teeth. The patients were divided into two equal groups, Group I received conventional RPD, which provides cross arch stabilization and a double Aker clasp was fabricated. Group II received new design of extracoronal castable precision attachment (OT Unilateral attachment). Evaluation of biting force by loadstar sensor, patients of both groups were evaluated at the time of prosthesis insertion, 3, 6, and 1 year later. Statistical analysis performing one-way analysis of variance followed by Tukey’s post hoc test to compare between all follow-up periods within each group, comparison between two groups regarding each follow-up period was performed by independent t-test. RESULTS: Both treatments yielded better after-treatment summary when compared with the baseline; however, better results were obtained and showed a statistically significant increase in Group II (OT unilateral design), especially after 3, 6 months, and 1 year later. CONCLUSION: From the results of this study, it was concluded that: It is preferable to use the new design of extracoronal castable precision attachment (OT unilateral) being simpler, more comfortable to the patients and give high masticatory efficiency in the form of biting force than conventional RPD.

Objectives: To assess the effect of a CAD-CAM protocol fabrication on the clinical fit accuracy of removable partial denture metal frameworks to abutment teeth. Methods: Fifteen patients with partial edentulism were selected to participate in this clinical study, and twenty dental arch rehabilitations were planned. For each dental arch (n=20), two cobalt-chromium frameworks were produced through two protocols: CAD-CAM production (experimental group); and conventional lost-wax casting technique (control group). Clinical fit accuracy was assessed using an indirect quantitative method to evaluate the gap between the framework occlusal rest and the corresponding rest seat. A silicone mold of that gap was obtained, digitized, and analyzed by micro-computed tomography. The two silicone molds obtained for each occlusal rest were overlapped and evaluated for thickness and volume. Data were analyzed with the paired t test for silicone thickness results and the Wilcoxon test for silicone volume results (α= 0.05). Results: Considering the two dependent variables under study, no statistically significant (p=0.441 for silicone thickness and p=0.204 for silicone volume) differences were found between groups. Conclusions: The results of this study suggest that the CAD-CAM protocol applied is a viable method for the production of removable partial denture metal frameworks.
