The assessment of the orthodontic mini-implants risk of fracture – a literature review

A modern method of anchorage provision, orthodontic mini-implants appear to provide a number of advantages for both complex and anchorage-demanding orthodontic cases. This review aimed to collect data about the risk of fracture of the mini-implants in orthodontics. The main topic in the mini-implant studies is addressed to the risk of fracture because of the inappropriate selection of mini-implants from the point of view of diameter, length, type of alloy, or insertion angle.
