MINISCREWS IN ORTHODONTICS

Ahmad abdulaziz Almulhim, Turki Mohamed A Alsubaie

Background: An adequate anchorage is often challenging in orthodontics and dentofacial orthopedics. The ability to control all the aspects of tooth movement is limited. The inadequate mechanical system to control anchorage leads to anchorage loss of the reactive unit. The conventional; Extraoral (headgear) and Intraoral (transpalatal arch) anchorage system is doubtful in providing absolute anchorage. Therefore, the need for orthodontic treatment that maximizes anchorage control and minimizes patient compliance requirements has led to the development of implant-assisted orthodontics (Bone supported anchorage/ skeletal anchorage) The aim of work: In this study, we aimed to understand advancement in orthodontics anchorage using miniscrew implants, the basic design of implant and classification, site of placement and risk factors associated. Methodology: The review is using the comprehensive search of Pubmed in American Journal Orthod Oral Surg from 1945 to 1984, J Clin Orthodontics (1983), and European Journal Orthodontics (1999). The terms used for the search are: miniscrew implants, bone supported anchorage, classification, risk factors Result: Using mini implants as a temporary anchorage device is a boon for an orthodontist, as there is no need for complicated clinical and laboratory procedures to facilitate safe and precise implant insertion. Miniscrews provide absolute anchorage, with the advantage of immediate loading when appropriate physiological forces are applied. Because miniscrew provides an alternative to conventional mechanics, the use of miniscrew has offered a wide variety of treatment alternatives, mainly while treating challenging cases. Further studies on the development of new design and miniscrew supported appliance in the orthopedic field is yet to be done. Keywords: Miniscrew Implants, Bone Supported Anchorage, Classification
