摘要
Low-temperature isotropic (LTI) pyrolytic carbon blade-type dental implants consisting of a graphite substrate and an LTI pyrolytic carbon coating have a strength that increases with the coating thickness. For implants having a coating thickness of about 0. 03 in. , average fracture loads of about 1500 lb and 230 lb were obtained in axial compressive loading and eccentric loading (e. g. , axial compressive loading plus a bending moment), respectively. Depending on the type of loading, the maximum stresses in the grahpite substrate were calculated to be very close to its compressive or tensile fracture strength. Also studied was the effect of a variety of defects on the overall strength of the implants.
