Aim: To find out the effect of monomer application for different time periods on tensile bond strength heat cured denture base resin and acrylic teeth. Methodology: Ninety specimens were fabricated as per ADA standards No 15 divided into 3 groups through purposive sampling technique. In Group 1 was applied teeth just before material packed. 2 10 seconds in 60 seconds. Universal testing machine ...

Options for restoring a single tooth include fixed partial denture, resin-bonded restoration and single-tooth implant. In this paper, we discuss the advantages and disadvantages of these methods and factors that must be considered when choosing between them for the replacement of a single tooth. Although in some cases a fixed partial denture is the most appropriate choice, implants have the adv...

PURPOSE In this 10-year longitudinal study we evaluated the amount of mandibular residual ridge resorption for 2 groups of subjects with complete dentures, one group with porcelain artificial teeth and the other with acrylic resin teeth. METHODS One hundred and nine patients who had undergone ridge extension procedures with skin graft and prosthetic rehabilitation with porcelain or acrylic re...

AIM This study is to evaluate the role of 1:1 v/v 30% trichloromethane and monomer solvent in enhancing the durability of bonding between cross-linked acrylic teeth and different heatcured denture bases with or without mechanical preparations made on ridge lap portion of the artificial teeth. MATERIALS AND METHODS Two high impact denture base resin materials (Trevalon HI, DeTrey, UK, and DPI ...

The debonding of acrylic resin teeth with the denture base resin has been related to several different factors of which contamination of the bonding surfaces with wax has been suggested as the major cause. The purpose of this study was to determine the efficient method of wax removal from denture teeth using hot water at different temperatures ranges. Acrylic rods were used as tooth analogues a...

This study evaluated the effect of denture base polymer type (heat- and microwave-polymerized), ridge lap surface treatment (with and without methyl methacrylate-MMA etching) and thermocycling on the microtensile bond strength (microTBS) of Biotone acrylic teeth. Flat-ground, ridge-lap surface of posterior artificial teeth were bonded to cylinders of each denture base resin, resulting in the fo...

The incorporation of computer-aided design/computer-aided manufacturing (CAD/CAM) technology into complete denture fabrication brings about several advantages to the fabrication process, providing better predictability of the desired outcomes and high accuracy of denture fit, mainly because the milling of prepolymerized acrylic resin eliminates the shrinkage of the acrylic base. Also, there is ...

Purpose: The purpose of this study was to determine the influence of silicone remover on tensile bond strength of eight silicone-resilient denture liners to a denture base resin. Durability of bond strength of resilient denture liner to denture base resin was also examined by thermal cycling test. Materials and Methods: Eight commercial silicone resilient denture liners were used. The specimens...

The purpose of this study was to evaluate the effect of degradation of a denture base resin on bond strength to relining resins. Denture base resin specimens were immersed under various conditions to simulate degradation. Tensile bond strength of denture base resin after immersion to relining resins was measured with or without surface grinding. The bond strength of denture base resin without g...
