ABSTRACT
The aim of this study was to evaluate whether the impact strength of a commercially available, heat polymerized acrylic denture base material could be improved using reinforcements. A total of 30 specimens [65 mm x 10 mm x 3 mm] were fabricated, the specimens were divided into 3 groups with 10 specimens each. They were Group 1 - conventional denture base resins, Group 2 - high impact denture base resins and group 3 - glass reinforced denture base resins. The impact strength of specimens was measured using charpy's test. One-way analysis of variance [ANOVA] was used to determine statistical differences among the impact strength of three groups. Data were analyzed by SPSS software and the results were obtained. The flexural strength values showed statistically significant differences among experimental groups [P<0.005]. Within the limitations of the study PMMA reinforced with glass fibers showed the highest impact strength values, and this was followed by PMMA reinforced with butadiene styrene and the least strength was observed in the conventional denture base resins
ABSTRACT
Injuries to the fingers are common in accidents at home, work, or play. Fingers as organs of manipulation have an important role in function and aesthetics. Moreover, for the majority of patients, the loss of the finger can lead to psychological problems. Peretz defines loss as "a state of being deprived of or being without something one has had and valued". The problem of replacing external parts of the body missing from surgery or trauma often falls to the maxillofacial prosthodontist. Maxillofacial prostheses replace lost body parts using artificial substitutes like acrylic or silicones. These prostheses support the patients psychologically and enhance their social acceptance. A case report is being presented where a custom made finger prosthesis; comfortable in use and esthetically acceptable to the patient was fabricated; using acrylic material. The prosthesis was retained by using a ring
