Abstract

The invention provides a dental implant surface treatment method. Due to sand blasting and acid etching treatment before soaking, dental implant surface roughness is increased to some extent; further,due to calcining in a later stage, dental implant surface roughness is increased remarkably, the implant bone combination capacity can be increased, and accordingly the dental implant clinical success rate is increased. A mixed acid formed by hydrofluoric acid and nitric acid is adopted for acid etching to provide a great sand blast dental implant surface morphology, great rough surface characteristics of dental implants are achieved, and interface bonding strength of a dental implant and bone combination surface is further improved. The method is simple in operation, convenient and simple intreatment, low in cost and applicable to industrial large-scale production.

Description

technical field [0001] The invention belongs to the technical field of biomedicine, and in particular relates to a surface treatment method of a dental implant. Background technique [0002] Dental implant has become a relatively mature clinical technology with optimistic application prospects. However, as a medical device implanted in the body, its surface properties and shape are important factors affecting the quality, which largely determines whether the dental implant can be combined with the bone for a long time and perform its function. The treatment of tooth loss with metal dental implants is recognized by doctors and patients. Prolonging the service life of implants and improving the bonding strength between implants and alveolar bone have always been the goals pursued by stomatologists. At the same time, It also reflects from the side that the contact area between the dental implant and the alveolar bone is insufficient, the bonding force needs to be improved, and...
