Abstract:
BACKGROUND:The physical properties and chemical composition of teeth are very similar with human bone tissue, and there are a larger proportion of inorganic components. Therefore, tooth can be considered as a potential repair material for autologous or alogeneic bone defects. OBJECTIVE:To prepare polyetheretherketone/odontogenic biphasic bioceramic composite, and to test its mechanical properties. METHODS: The humanin vitro teeth of clinical waste were colected. The organic components were removed after a preliminary calcination. Another calcination was conducted after soaking in diammonium phosphate solution for 24 hours to prepare the biphasic ceramics with the main components of hydroxyapatite and β-tricalcium phosphate. The biphasic ceramics were ground and sieved using 200-mesh sieve folowed by impregnation in organic foam to prepare polyetheretherketone/odontogenic biphasic bioceramics. Phase analysis, scanning electron microscopy, elemental analysis, porosity, compressive strength and bond strength test were conducted. RESULTS AND CONCLUSION:Polyetheretherketone/odontogenic biphasic bioceramics presented porous network structure and interconnected holes, with the aperture of 100-800 μm, porosity of 73.65%, compressive strength of (165.260±11.703) N, bond strength of (14.63±6.21) MPa. P element content accounted for 19.8%, and Ca element content accounted for 40.5%. The main phases were β- tricalcium phosphate and hydroxyapatite. These results demonstrate that polyetheretherketone/odontogenic biphasic bioceramics have good mechanical properties.
