Basic studies on visible light-curing resin as a denture base. Part 5 Its junctional strength with resin teeth.

Abstract

In the present study, the authors examined the junctional strength of visible light-curing denture base resin and resin teeth in comparison with that of conventional heat-curing resin. The results obtained were as follows: 1) When visible light-curing resin was used as the resin block on which resin teeth were implanted, the fracture strength for resin teeth having retention holes in the basal planes, was approximately 1.5 times as large as that for teeth with no retention holes. Also, samples in which the resin tooth surface was treated with dichloromethane had a value approximately twice as large. 2) When heat-curing resin was used as the resin block on which resin teeth were implanted, employing visible light-curing resin for repair, the fracture strength was small in comparison with the values obtained for specimens described in 1).

Mandibular Anterior Immediate Denture Using Visible Light Cure Acrylic

“…It exhibits greater [10] or at least comparable [12] transverse strength and micro-hardness as compared to conventional denture based acrylic resin. Comparison of its mechanical properties to other polymers [11], and investigations into its interaction with various relines materials [13] [14] and its bond strength to denture teeth [7] have also been conducted. It has also been used in fabricating a hollow obturator [17].…”
