One of the reconstructive choices for the completely edentulous patient is the placement of multiple implants and the fabrication of a fixed implant-supported complete denture. These patients experience an improvement in masticatory performance over patients who wear complete dentures. The fixed-implant complete denture consists of a metal bar with acrylic resin and denture teeth connected to i...

PURPOSE The discoloration of acrylic resin denture bases may lead to significant esthetic problems. The aim of this in vitro study was to investigate the effects of frequently consumed drinks on the color changes of fresh and aged, heat-polymerized, conventional acrylic resin. MATERIALS AND METHODS Eighty-four, heat-polymerized acrylic resin specimens (4 mm x 5 mm x 30 mm) were fabricated. Ha...

background and aims. polymethyl methacrylate, pmma, is widely used in prosthodontics for fabrication of removable prostheses. this study was undertaken to investigate the effect of adding silver nanoparticles (agnps) to pmma at 2% and 0.2% concentrations on compressive and tensile strengths of pmma. materials and methods. the silver nanoparticles were mixed with heat-cured acrylic resin in an a...

OBJECTIVE To determine the degree of cure of a light-cured resin-modified glass ionomer (RMGI) under molar bands compared with a light-cured resin and a dual-cured resin. MATERIALS AND METHODS The 3 cements used were Fuji Ortho LC, Eagle Spectrum resin, and Variolink II dual-cure. Each sample was indirectly light cured for 20 seconds (10 seconds occlusally, 10 seconds cervically) under sectio...
