Data dealing with successful or unsuccessful acrylic tooth implants have accumulated gradually during the past 20 years. Flohr' studied plastic material as a possible substitute for natural teeth by placing screw-type acrylic roots into surgically created alveolar sockets. He reported that normal connective tissue formed against the acrylic, and only minimal infiltration occurred. Hodosh, et al...

PURPOSE To investigate the ability of an open capsule device to prevent posterior capsule opacification. METHODS A total of 40 eyes of 20 New Zealand white rabbits were randomly divided into six similar groups of 6 to 7 eyes each. After crystalline lens evacuation, one control group (group A) was implanted with a hydrophilic acrylic intraocular lens and no device, and another control group (g...

Five combinations of materials commonly used for intermaxillary records in cases of bilateral free end saddle were evaluated: acrylic resin base + wax; acrylic resin base + wax + ZOE paste; acrylic resin base + wax + Duralay resin; condensation silicone; and acrylic resin plate + irreversible hydrocolloid. The materials were evaluated by measuring the vertical distance between pairs of referenc...

PURPOSE To compare biofilm formation by Staphylococcus epidermidis on different intraocular lens (IOL) materials. METHODS The S. epidermidis strains, ATCC 12228 (American Type Culture Collection) and ATCC 35984 (biofilm-producer) were used. Biofilms were cultivated on disks of different IOL materials: silicone, PMMA (polymethylmethacrylate), acrylic, or MPC (2-methacryloyloxyethyl phosphorylc...

Purpose: Denture-related stomatitis is probably the most common form of oral candidiasis and its reported prevalence varies widely ranging up to 65%. In this in vitro study, we evaluate the effect of delmopinol application on Candida albicans adherence on heat-cured acrylic resin, cold-cured acrylic resin and microwave-cured acrylic resin. Materials and methods: A total of 40 specimens of each ...

This study aimed to evaluate the tensile and transverse bond strength of chairside reline resins (Tokuyama Rebase II, Mild Rebaron LC) to a thermoplastic acrylic resin (Acrytone) used for non metal clasp denture. The results were compared with those of a conventional heat polymerized acrylic resin (Paladent 20) and a thermoplastic polyamide resin (Biotone). The failure sites were examined by sc...

INTRODUCTION The aim of the study is to evaluate interfacial bond strength between silicone prosthetic elastomers and polymethylmethacrylate (PMMA). MATERIALS AND METHODS Silicone elastomers were attached to PMMA and a total 120 specimens were fabricated which were then subdivided into 12 sub-groups. Each sample was then subjected to laboratory test to determine the bond strength. The specime...
