Description
Technical Field
The invention relates to the technical field of oral implant orthopedic treatment, in particular to a double-acid treatment device applied to the surface of a dental implant and a preparation method thereof.
Background
Since the 'osseointegration theory' of titanium metal was discovered and created in the last 50 th century by the teaching of Branemark in sweden, titanium metal is popularized on dental implants at first, and with the general acceptance of the 'osseointegration theory' of titanium metal, titanium metal is widely popularized in orthopedic fields such as bone trauma, bone joints, bone fusion devices, various bone nails and the like.
The initial titanium implant surface is only machined, and with long-term clinical research, the roughened surface of titanium metal is found to be more favorable for osseointegration, and various surface roughening processes of titanium metal are generated, such as sand blasting, shot blasting, plasma titanium spraying, electroerosion and the like. The roughened surfaces are more favorable for the combination of bone cells and titanium metal, increase the combination area of bone and titanium and improve the speed and strength of bone combination. The roughened surface of titanium metal is now commonly used on osseointegrated implants.
Although the roughened titanium surface increases the strength of osseointegration and shortens the time of osseointegration, after the surface roughening treatment, some defects and risks appear on the surface, which are shown in the following concrete points:
1. the surface of the titanium alloy is provided with a large amount of foreign matters, for example, sand blasting materials such as alumina and silicon dioxide are commonly used in sand blasting, impurities such as iron, lead and carbon are commonly present in the materials, the materials and the impurities can be embedded and combined with the surface of the titanium metal after being collided with the surface of the titanium metal at a high speed through high-pressure air, and the materials and the impurities cannot be removed by subsequent cleaning and other treatment methods. As are processes such as shot peening, plasma spraying, and the like.
2. Surface modification is carried out on the surface through high-temperature treatment, such as high-temperature plasma spraying, electro-corrosion treatment and the like, the surface is liquefied through local high temperature of the surface to form a roughened surface, in the surface high-temperature sintering process, a large amount of peripheral impurity elements such as treatment media (such as electric spark liquid) and air are dissolved in the surface to modify the surface, and various impurities are dissolved in the surface to form an oxidized surface containing impurities.
3. Various irregular cracks, micropores and other surface defects can be formed in the coarsening process, so that some liquid media in the later working procedure, such as cleaning solution, processed cooling oil and the like can permeate into the surface defects. The final cleaning process such as ultrasonic cleaning is difficult to clean the impurities in the micro-gaps, and the impurities of the grease are very unfavorable for the osseointegration.
In summary, the roughened surface has certain defects such as foreign matters, impurities, surface modification and the like, and clinical symptoms such as infection, insufficient osseointegration area, slow osseointegration, bone atrophy and the like appear in clinic due to the defects.
