Evaluating the Effect of Polyetheretherketone Particles Addition on Water Sorption and Solubility of Polymethylmethacrylate Denture Base Material

Abstract

Aims: To assess water sorption and solubility of PMMA after incorporating with polyetheretherketone particles (vectrex peek polymer PEEK) material with a different percentage (1%, 2%, and 3%). Materials and Methods: The PEEK particle size of 130μm. Peek with (1%, 2%, 3%by wt.) concentrations were added to the PMMA resin base to compare with the PMMA with no additives (control). The conventional heat-curing method was applied using a water bath to polymerize the specimens and study water sorption and water solubility of prepared samples. Study data were analysed via One-way ANOVA performed at a significant P-value of (p≤0.05) and confidence. Fourier transform infrared spectroscopy used to detect any chemical modification that occurs. Results: After comparing the results show a significant difference in Water sorption of PMMA/PEEK. Water Solubility shows no significant difference compared to other tested groups (p≤0.05). Conclusions: The PEEK particles use it as dental filler at 1%,2% and 3% wt. incorporating PMMA material with3% PEEK material has lowest mean value for water sorption and solubility
