Background

Since the Linkow doctor applied the implant anchorage to orthodontic clinics for the first time in 1969, nearly 50 years of history have existed. In this half century of clinical applications, orthodontic anchorage implants are constantly being improved to accommodate clinical needs. Since the last 90 s, with the continuous reduction of the volume of anchorage implants, the implantation position is more flexible and is increasingly favored by orthodontists. The Meta analysis of Papadopoulos and the like shows that the success rate of the micro-implant in clinical application is about 87.7 percent, because the success rate of the micro-implant in clinical application is influenced by a plurality of factors, the loosening and falling of the implant is an important factor causing the failure of the micro-implant in clinical application, and the research of different scholars shows that the falling rate of the implant is about 10 to 30 percent.
