BACKGROUND The utilization of computer-assisted designing and computer-assisted milling CAD\CAM resins in the fabrication of removable prostheses is a modern-day concept that offers many advantages over the use of the traditional polymethylmethacrylate (PMMA). AIM This study instigated some of the mechanical properties of CAD\CAM denture base resin including the amount of residual monomer. ...

This research tested the hypothesis that interaction between time and salinity reduces water absorption potential of a hydrogel – Poly (Acrylamide-co-Potassium Acrylate) influence degradation residual acrylamide monomer. The experimental design was completely randomized split-plot with four replications. treatments were periods (30, 60, 90 120 days) levels hydrating solution (distilled = 0.003,...

2, 2-Bis [4- (2-hydroxy-3-methacryloyloxypropoxy) phenyl] propane (bis-GMA) is widely used in dentistry as a monomer of composite resin system and their bonding agents. Since bis-GMA is not purified, its isomers and some chemicals such as residual initiator remain in the commercial product. Bis-GMA and iso-bis-GMA were separated from bis-GMA monomer by HPLC. NMR spectra of both monomers were re...
