Wear resistance of injection-molded thermoplastic denture base resins
Objective This study investigated the wear resistance of injection-molded thermoplastic denture base resins using nanoindentation instrument. Materials and methods Six injection-molded thermoplastic denture base resins (two polyamides, two polyesters, one polycarbonate, one polymethylmethacrylate [PMMA]) and a PMMA conventional heat-polymerized denture-based polymer control were tested. Elastic...
متن کاملFailure strengths of denture teeth fabricated on injection molded or compression molded denture base resins.
STATEMENT OF PROBLEM Denture tooth fracture or debonding remains a common problem in removable prosthodontics. PURPOSE The purpose of this in vitro study was to explore factors determining failure strengths for combinations of different denture tooth designs (shape, materials) and injection or compression molded denture base resins. MATERIAL AND METHODS Three central incisor denture tooth d...
متن کاملPhysical properties of four acrylic denture base resins.
Resistance to impact fracture and high flexural strength are desirable properties of denture base acrylics. The purpose of this laboratory study was to determine the Izod impact strength, the flexural strength, the flexural modulus, and the yield distance for four premium denture resins. Bar specimens 86 x 11 x 3 mm of Lucitone 199, Fricke Hi-I, ProBase Hot, and Sledgehammer Maxipack were fabri...
متن کاملInvestigation of the cytotoxicity of thermoplastic denture base resins
PURPOSE The purpose of this study was to investigate the in vitro cytotoxicity of thermoplastic denture base resins and to identify the possible adverse effects of these resins on oral keratinocytes in response to hot water/food intake. MATERIALS AND METHODS Six dental thermoplastic resin materials were evaluated: three polyamide materials (Smile tone, ST; Valplast, VP; and Luciton FRS, LF), ...
متن کاملEffect of denture cleansers on color stability, surface roughness, and hardness of different denture base resins
AIM The purpose of this study was to evaluate the effect of different denture cleansers on the color stability, surface hardness, and roughness of different denture base resins. MATERIALS AND METHODS Three denture base resin materials (conventional heat cure resin, high impact resin, and polyamide denture base resin) were immersed for 180 days in commercially available two denture cleansers (...
