Characterization of multiwalled carbon nanotube-polymethyl methacrylate composite resins as denture base materials.
STATEMENT OF PROBLEM Most fractures of dentures occur during function, primarily because of the flexural fatigue of denture resins. PURPOSE The purpose of this study was to evaluate a polymethyl methacrylate denture base material modified with multiwalled carbon nanotubes in terms of fatigue resistance, flexural strength, and resilience. MATERIAL AND METHODS Denture resin specimens were fab...
متن کاملSynthesis and thermal characterization of polymethyl methacrylate
PMMA with molecular mass (PMMA Mw: 1.2×105) was synthesized through AIBN initiated free radical polymerization methyl methacrylate at 100 ± 1°C.The synthesized polymer was characterized through GPC coupled with RI detector in presence of THF as mobile phase at 1.0 mL/ min and simultaneous TG-DTA-DTG in nitrogen. TG data were used to investigate the non-isothermal kinetics of solid-state decompo...
متن کاملErratum - Influence of various metal oxides on mechanical and physical properties of heat-cured polymethyl methacrylate denture base resins
PURPOSE To evaluate the effect of various metal oxides on impact strength (IS), fracture toughness (FT), water sorption (WSP) and solubility (WSL) of heat-cured acrylic resin. MATERIALS AND METHODS Fifty acrylic resin specimens were fabricated for each test and divided into five groups. Group 1 was the control group and Group 2, 3, 4 and 5 (test groups) included a mixture of 1% TiO2 and 1% Zr...
متن کاملSalvage of Infected Nasal Reconstruction with a Polymethyl Methacrylate Spacer
Total nasal reconstruction is a challenging multistage procedure. Infections can destroy the cartilage framework and seriously compromise the result. The use of polymethyl methacrylate with antibiotics as a spacer has been described in the treatment of skeletal infections. Using this same principle, the use of a polymethyl methacrylate with antibiotics spacer for an infected nasal reconstructio...
متن کاملAgeing and moisture uptake in polymethyl methacrylate (PMMA) bone cements☆
Bone cements are extensively employed in orthopaedics for joint arthroplasty, however implant failure in the form of aseptic loosening is known to occur after long-term use. The exact mechanism causing this is not well understood, however it is thought to arise from a combination of fatigue and chemical degradation resulting from the hostile in vivo environment. In this study, two commercial bo...
