English Abstract

About 90-95 % of dentures are fabricated from Poly (methyl methacrylate) which is a preferred material for removable complete and partial prostheses.

In this study, opaque dental porcelain powder used as ceramic filler was incorporated into the PMMA matrix.

The resulting composite was tested for its environmental and thermal qualities for applicability in dental restoration.

The diagnoies results of filled and unfilled samples showed that the filler-filled formulations had less water solubility, less absorption and reduced weight loss after 28 days of immersion in SBF at 37ºC.

The water absorption and solubility values of all filled formulations were below the values specified by the ISO standards for denture base materials.

The degradation temperature of the filler-filled PMMA samples was shown to be slightly higher than that of the unfilled samples.

The environmental and thermal feasibility tests approved that the prepared composite denture base material is applicable in denture restorations.
