Abstract
HA coating was obtained by means of plasma spray technique. The properties of HA coating were studied by XRD, IR, SEM and mechanical tests. The coating may be pure HA, pure oxyapatite or a mixture of HA and oxyapatite by different spray-techniques. The porosity, surface roughness, BET surface are analysis and strength are raltive to the size of sprayed HA greatly. Animal experiments have demostrated that the HA-coated dental implants was a promising one because of its superior properties in biomechanical compatibility as well as biocompatibility. Having considered the properties of materials and the biomechanical requirements of dental implants sufficiently, a set of two-piece cylindrical HA-coated titanium dental implant were designed. Over 500 implants have been used in clinical application. A two-year follow-up study has shown that the result is satisfactory and the success rate is 98%.
This project was supported by the National Natural Science Foundation of China and the National Educational Committee of China.
