Abstract:
Anchorage control is important for efficient orthodontic treatment. Osseointegration of implant -bone encouraged orthodontists to use implants as stationary anchorage. However, it has some defects such as root damage. This article was to explain factors significantly contributing to damage; histological changes and turnover of the damage, location-related factors(vertical position, sagittal position, placement side), implant-related factors(material, length, diameter), insertion-related factors(mode, direction, moment) and orthodontic-related factors(mode of loading) have positive effects on the damage. After mini-screw contacts the tooth, the majority show repair and almost complete healing within a few weeks after removal of the screw or the orthodontic force without complications.
Key words: mini-screws, root damage, paradentium damage
