Abstract

The invention discloses a preparing method for constructing an apatite nanowire similar to a parodontium fiber bundle on a titanium micro-arc oxidation coating surface through microwave moisture, relates to a preparing method for constructing the nanowire similar to the parodontium fiber bundle on the titanium micro-arc oxidation coating surface and aims at solving the problems that in the existing dental implant technology, a structure similar to the parodontium fiber bundle is in shortage in a tooth root implant, and surgeries are likely to fail. The method includes the first step of titanium material pretreatment, the second step of micro-arc oxidization treatment and the third step of microwave moisture treatment. The preparing method is used for preparing for constructing the apatite nanowire similar to the parodontium fiber bundle on the titanium micro-arc oxidation coating surface through the microwave moisture.

Description

technical field [0001] The invention relates to a preparation method for constructing nanowires similar to periodontal ligament fiber bundles on the surface of titanium micro-arc oxidation coating. Background technique [0002] At present, dental implant technology is an important means of repairing tooth defect or loss, but the root implant lacks a structure similar to the periodontal ligament fiber bundle, which easily leads to the failure of the operation, and there is no fundamental clinical solution at present. The normal periodontal tissue structure consists of the root outward, followed by cementum, periodontal ligament, alveolar bone and gingiva. Cementum is a thin layer of bone-like tissue that surrounds the surface of the tooth root. The periodontal ligament is composed of dense connective tissue. Most of the fibers are arranged in bundles. One end of the fiber is buried in the cementum, and the other end is buried in the alveolar In the wall of the socket bone, t...
