Preparation method and surface hydrophilicity of implant nanotube array through secondary anode and reaming on the surface of implant material

Abstract

The invention discloses a preparing method of an implant nanotube array with an implant material surface subject to secondary anode and broaching treatment and surface hydrophilicity. According to the technical scheme, the method comprises the steps that firstly, pure titanium or a titanium alloy is provided for machining and molding a dental implant base body, and the base body is subject to mechanical polishing, cleaning, drying, chemical polishing and drying; secondly, the implant base body is placed in an anode of an electrolytic tank to be subject to primary anode oxidization; thirdly, the implant base body subject to primary anode oxidization is placed in a solution to be corroded and oxidized; fourthly, after cleaning, secondary anode oxidization is carried out; fifthly, the base body is placed in a phosphoric acid solution to be subject to broaching; sixthly, after deionized water washing and drying, a contact angle test is carried out, and hydrophilic performance data are obtained; the method has the beneficial effects that pore sizes of the implant nanotube array obtained after secondary anode and broaching treatment are more even in distribution, collagenous fiber size and arrangement in bone tissue can be simulated, the elasticity modulus similar to the bone tissue is obtained, and the implant surface performance is optimized.

Description

technical field [0001] The invention relates to the field of surface modification of dental planting materials (implants), in particular to a preparation method and surface hydrophilicity of implant nanotube arrays on the surface of the planting material through secondary anode and hole expansion. Background technique [0002] Titanium and titanium alloys have good surface and mechanical properties and are widely used in dental implants. In fact, it is due to the formation of a dense oxide layer with a thickness of about 1.5-10nm on the titanium surface, which guides and regulates the regeneration response of the tissue around the implant and integrates with the surrounding bone. Studies have shown that the long-term failure rate of implants has not been completely resolved, mainly due to unsatisfactory early cell adhesion, insufficient implant-bone interface integration, and peri-implantitis caused by bacterial infection around the implant, which eventually leads to implant...

Problems solved by technology

Studies have shown that the long-term failure rate of implants has not been completely resolved, mainly due to unsatisfactory early cell adhesion, insufficient implant-bone interface integration, and peri-implantitis caused by bacterial infection around the implant, which eventually leads to implant failure. Loss of osseointegration interface, implant dentures loosen and fall off

Although titanium has good mechanical properties, corrosion resistance and biocompatibility, as a biologically inert material, it is not bioactive and has weak ability to induce osteogenesis. research hotspots
