✦ Synopsis

This work has been undertaken in an attempt to develop improved materials for the construction of dentures. In particular, a material was sought that would combine radiopacity with high impact resistance. Eight particulate radiopaque glasses were prepared and incorporated into poly(methy1 methacrylate) denture base material, and the properties of the resultant composites were measured. Experiments were also carried out with glass fiber fillers, which were found to increase impact strength. It was shown that the incorporation of both a particulate radiopaque glass and glass fiber, 20% of each, yielded composites with improved properties.

The effect of pure alcohol as well as several alcoholic drinks on the static and dynamic strength and surface quality of denture base poly(methyl methacrylate) was investigated. Wetting tensile specimens with alcohol led to a reduction of their static strength by 16.1% and their fatigue strength by
