Latest research on zirconia implant surface treatment / 中国组织工程研究

ABSTRACT

BACKGROUND: Recently, zirconia ceramic implants have been reported to be used in clinic. Increasing studies on surface treatment of ziconia implants have been done, in order to promote bone-implant osseointegration and increase the success rate of implantation. There are no recognized surface treatment techniques of zirconia implants as yet.OBJECTIVE: To summarize the research progress in surface treatment techniques of zirconia implants.METHODS: The first author searched the CNKI, PubMed and Web of Science databases for relevant articles published from January 2000 to October 2016. The keywords were zirconia or zirconium, implant, surface treatment in Chinese and English, respectively. The search condition was((zirconia or zirconium) AND implant) AND surface treatment. Here,we reviewed the surface treatment techniques of zirconia implants, and introduced the properties, the surface treatment techniques and commercialization of zirconia implants.RESULTS AND CONCLUSION: Totally 23 papers were included in result analysis. Commonly used surface treatment technologies of zirconia implants include sand blasting, acid etching, sandblast and acid-etching, selective filtration etching, laser, ultraviolet and coating. These technologies all contribute to improving the surface activity of the implant,increasing the roughness, and promoting bone bonding to a certain extent.Because of the very limited experiments,further investigations are required to explore the optimum technique for the surface treatment of zirconia implants.
