Abstract:
BACKGROUND: Micro-arc oxidation, also be known as micro-plasma oxidation or anodic spark deposition, is a new technology that can in situ grow ceramic coating directly on the surface of non-ferrous metals. And the ceramic coating has such characteristics as high corrosion resistance, good wear resistance, etc. It is advantageous to the osseointegration between implant and bone that the ceramic coating is able to produce porous, rough oxide film on the surface layer of the implant, which improves the biological reaction of the bone interface so as to affect the number of bone-forming cells, ype, products of cell, and the expression of the product.OBJECTIVE: To observe the osseointegration between bone and implant, and to analyze induced action of metal trace elements to bone-formation's marker (ALP). METHODS: A computer-based online search was conducted in PUMMED and Chinese Journal Full-text Database with the key words of "micro-arc oxidation, synosteosis, titanium, magnesium" in both English and Chinese between 1995 and 2009. Additionally, hand-made retrieval was performed for articles about micro-arc oxidation and microelement. Among 96 articles, 34 references were excluded due to unrelated and duplicated articles, and 28 ones were excluded due to long-term publication, 34 ones were included in the final analysis.RESULTS AND CONCLUSION: It is believed that the surface modification methods on microelement and micro-arc oxidation ceramic coating on Ti-based implant will become the mainstream process to improve the rate of implant-bone integration.However, the clinical application still needs to be further studied.
