Abstract:

BACKGROUND: Mini-implants are widely applied in the clinical treatment of orthodontics and orthognathics, because they can provide absolute skeletal anchorage. However, the relatively high failure rates have always been their major drawback, and how to improve the success rates of mini-implants becomes the main research direction in recent years.

OBJECTIVE: To summarize the factors influencing the stability of mini-implants.
METHODS: A computer-based search of Wanfang, VIP and PubMed databases was performed using the keywords of “mini-implants, stability, success rate, osseointegration” in Chinese and English.
RESULTS AND CONCLUSION: Mibni-implants are an effective means of anchorage control. In clinics, the factors such as implant design, health status of patients, implantation methods and regions, loading patterns and maintenance after implantation will all have an influence on the stability and success rates of mini-implants. To improve the success rate of the mini-implants, the selection of appropriate implant area is necessary in clinical applications, for example, thicker cortical bone and higher mini-implants are recommended clinically; using reasonable and loading implants, studies have shown that non-scored mini-implants is beneficial to reduce the dropout rate of mini-implants during early orthodontic loading; maintenance during healing periods after implantation is emphasized, and currently, stress loading on the mini-implants is preferred immediately after implantation or earlier, which can have a better success rate.
