Retração dos dentes superiores com mini-implantes Extra-alveolares na má oclusão classe ii

Abstract

A part of the population that looks for orthodontic treatment in the dental office is patients with Angle Class II, Division 1 malocclusion. Some therapeutic approaches involve retraction of the upper teeth, involving extractions or not, extraoral and/or intraoral devices. In retraction, a critical point is the support anchoring for this movement. Given this, the use of extra-alveolar mini-implants has stood out due to its obtaining absolute maximum anchorage, becoming an important aid in orthodontic treatments. Its low cost, favorable aesthetics and minimal need for patient collaboration during treatment cause good acceptance to occur, in addition to providing greater predictability in orthodontic treatment to the dental surgeon. Therefore, this study aims to carry out a literature review about the retraction of the upper teeth with the use of extra-alveolar mini-implants inserted in the infra-zygomatic crest region.
