Problems solved by technology

However, after dental implant implantation, how to quickly and effectively form the optimal surface pore size and roughness for osseointegration, so as to obtain better initial and long-term stability after healing, has not yet reached a clear conclusion. Surface modification methods and process parameters are still the subject of research in recent years

Embodiment Construction

[0017] A method for surface treatment of a dental implant of the present invention, the embodiment is as follows figure 1 As shown in the flow chart, it includes the following steps:

[0018] first as figure 1 As shown in step 101, a dental implant is provided, and the dental implant is made of titanium or titanium alloy.

[0019] Then as figure 1 As shown in step 102, sandblasting is performed on the dental implant. Usually, sandblasting, also known as shot peening, uses hard sand particles to fly out at high speed with external power to hit the material on the object to be treated, so that the surface produces a set bite. Sprayed surfaces, or to remove stains and oxides, as well as to eliminate scratches and clean surfaces. The mechanism of sandblasting is divided into two types: dry type and wet type. Generally speaking, the wet type is more suitable for sandblasting with a particle size of about 15 microns (um). The materials used for sandblasting generally include st...

Abstract

The present invention discloses a surface treatment method of a dental implant, wherein a titanium or titanium alloy artificial implant is used. Through partial treatments which comprise sand spraying, acid pickling and coating hydroxyl calcium phosphate with biocompatibility, a specific porous structure is generated on the surface of the artificial dental implant, and the artificial dental implant is also provided with a partial porous hydroxyl calcium phosphate coating. Therefore osteoblast-like cell and bone integration speed can be increased, and furthermore the treatment period in artificial tooth implantation is reduced.

Description

technical field [0001] The invention relates to a method for surface treatment, in particular to a method for modifying the surface of a dental implant. Background technique [0002] At present, in the field of dental treatment, in addition to the traditional "fixed prosthetics" and "removable dentures" for the treatment of tooth defects, "Dental Implant" has gradually become one of the mainstream options for dental treatment. [0003] Looking back, in 1969, Branemark published the research results on titanium alloy artificial tooth roots, opening a new era of "dental implants". In 1972, Predecki et al. observed experimentally that an irregular "dental implant" surface can promote faster bone growth and have good mechanical fit and adhesion. In 1976, Schroeder et al. first observed the direct contact between bone and implant in tissue sections; and in 1992, Bower et al. also conducted histological studies, confirming the direct contact between these bones and implants. As ...
