Tooth intrusion using mini-implants

Introduction: Amongst the different types of orthodontically-induced tooth movements, intrusion undoubtedly features as one of the most difficult to achieve. Conventional intrusive mechanics, although viable, involves a rather complex side effect control. This is due, to a large extent, to a difficulty in securing a satisfactory anchorage. Within this context, mini-implants offer an effective skeletal anchorage which has become an invaluable asset to orthodontists since it renders the intrusion of both anterior and posterior teeth an increasingly streamlined procedure from a mechanical standpoint. Objective: It is the purpose of this article, therefore, to describe and demonstrate clinically the various ways in which mini-implant can be utilized as an anchorage device to promote intrusion.
