SURFACE CHARACTERISTICS OF HA COATINGS ON DENTAL IMPLANTS

摘要

A manufacturing method of a dental implant coated with toothash using nano-tubes is provided to improve the biocompatibility and osseointegration of a dental implant and to be permanently implanted on a user's mouth. A manufacturing method of a dental implant coated with toothash using nano-tubes includes the steps of: forming nano-tubes on the surface of a dental implant; and coating toothash or artificial HA on the surface of the nano-tubes. The method of forming nano-tubes on the surface of the dental implant uses an anodization method, and the method of coating toothash or artificial HA uses a physical vapor deposition. A pulse laser deposition method is used as the physical vapor deposition, and the basic pressure is 9.9x10-6Torr, the temperature is 500deg.C and the time is 20 minutes.
