Miniscrew implantology for anchorage

Mini-implants, also called mini-screws or temporary anchorage devices (TAD), are very small screw-like gadgets used more widely in orthodontic treatments. They are becoming popular because they provide good anchorage, which means that they are fixed to bone and then linked to a tooth or a segment of teeth to slowly move them during treatment.
Anchorage is a stable base on which an orthodontic force can be applied to move teeth. Ideally the anchorage should stay in place and not move at all. Before mini-implants existed, conventional anchorage was either big teeth (example molars or canines) or orthodontic appliances (whether inside or outside the mouth). But previous anchorage had limitations: a molar can still move when too much force is applied to it, and an appliance is fixed to other teeth that can move as well. Conventional anchorage can still give good results when well managed, but mini-implants provide more stability.

The goal of orthodontic treatment is to improve the patient's life through enhancement of dentofacial functions and esthetics. Anchorage, defined as a resistance to unwanted tooth movement

Orthodontic anchorage is an important factor in obtaining good treatment results. Stable anchorage is a pre-requisite for orthodontic treatment with fixed appliances. Traditional appliances for reinforcement of anchorage have included headgear and intraoral elastics. The inclusion of implants for skeletal anchorage can move a tooth without the use of headgear and intraoral elastics.
