Abstract

The invention discloses a production method of a titanium implant surface composite coating used for the stomatology department, and relates to the field of biomedical materials. The method comprises preprocessing of a titanium plate, micro arc oxidation treatment, preparation of a sol solution, and production of the composite coating. A film is produced on the surface of pure titanium by adopting butyl titanate as a precursor and diethanolamine as a complexing agent and adding polyethylene glycol used as a template through a sol-gel technology, so the bioactivity of the titanium material is improved, and the corrosion resistance is enhanced.

Description

technical field [0001] The invention relates to the field of biomedical materials, in particular to a method for preparing a composite coating on the surface of a titanium implant used in stomatology. Background technique [0002] Titanium and titanium alloys have been widely used in the fields of plastic surgery and implantology, and are currently the preferred materials for dental implant restoration. However, pure titanium has low hardness, poor anti-friction performance, and low biological activity on the surface. If it is directly implanted into the human body, there are problems such as long osseointegration time, low bonding strength, and potential impact of free metal ions on human tissues. Therefore, how to obtain specific physical morphology, chemical composition and biochemical modification on the surface of titanium metal through surface modification, so as to form a biological combination with bone tissue, shorten the implantation cycle, obtain early osseointeg...
