Effect of light aging on silicone-resin bond strength in maxillofacial prostheses.

Purpose: The aim of this study was to investigate the effect of accelerated light aging on bond strength of a silicone elastomer to three types of denture resin.

Materials And Methods: A total of 60 single lap joint specimens were fabricated with auto-, heat-, and photopolymerized (n = 20) resins. An addition-type silicone elastomer (Episil-E) was bonded to resins treated with the same primer (A330-G).

The effect of immersion cleansers on gloss, colour and sorption of acetal denture base material.

Objective: To study the effect of peroxide and hypochlorite cleansers on gloss, colour and sorption of acetal denture resins.

Materials And Methods: Pink acetal and thermoplastic acrylic resins were evaluated. Thirty-five specimens 39 × 39× 1.

Effect of immersion cleansing in color stability and hardness of soft denture reliners.

Hygienic care of removable prostheses is important, and denture cleansers selected must be efficient and maintain the physicomechanical properties of soft reliners. Microwave energy has been reported to increase the sanitation effectiveness of denture cleansers. The purpose of the study was to evaluate hardness and color stability of some visible light polymerized and autopolymerized soft reliners after exposure in different denture-cleansing treatments.
