The Effectiveness of Hydroxyapatite as a Filler in Denture Base Materials Based on Polymethyl Methacrylate to Improving Mechanical Properties
Poly (methyl methacrylate) or PMMA is an acrylic material has been used widely as a denture base material. The denture base materials should exhibit good mechanical properties and dimensional stability in moist environment. Hydroxyapatite (HAp) as a filler is added to improve the mechanical properties of the denture base. Process for the manufacture of denture base composites consists of a synthesis of polymethyl methacrylate (PMMA) with suspension polymerization process, treatment filler hydroxyapatite, mixing component powder and liquid, molding and curing process. hydroxyapatite concentrations used were 0%, 1.5%, 3%, 4.5%, 6%, 7.5% and 9%. Characterization of PMMA product resulted an average particle size of 48.7 microns, dominant percentage of taxicity in atactic 39.5% and syndiotactic 60.7%. In the FTIR spectra, no impurity compounds were detected in PMMA products. The highest tensile strength value was found in hydroxyapatite which contained 6%, which was 63.87 MPa according to the PMMA standard for denture base.
