RESUMOO uso dos mini-implantes como recurso de ancoragem para distalização de molar superior tem a finalidade de evitar a movimentação indesejável da unidade de reação, proporcionando uma série de vantagens quando comparados à aparelhos extrabucais ou intrabucais, aparelhos estes, que necessitam da colaboração dos pacientes e tem um comprometimento estético. Por isso, os mini-implantes têm sido cada vez mais associados aos diversos sistemas distalizadores, buscando uma ancoragem absoluta, facilitando e aprimorando os procedimentos de ancoragem ortodôntica, reduzindo o tempo e dando uma maior previsibilidade ao resultado do tratamento. A distalização dos molares superiores tem se mostrado uma excelente técnica para correção de classe II e III de Angle. O objetivo deste trabalho é realizar uma revisão de literatura, avaliando os métodos utilizados para se obter uma eficiente distalização de molar ancorados por mini-implantes.Palavras – chave: Ancoragem esquelética – Mini-implantes – Microparafuso ortodôntico ABSTRACT            The use of miniscrews anchorage for distalization of maxillary molars is intended to prevent unwanted movement of the reaction unit, providing a series of advantages when compared to the extraoral or intraoral devices, appliances those which require the patients’ collaboration and have aesthetical problems. So the miniscrews have been increasingly associated with various distalization systems, seeking an absolute anchorage, facilitating and improving the orthodontic anchorage procedures, reducing treatment time and providing greater predictability to the treatment outcome. The maxillary molar distalization has proven to be an excellent technique for correction of class II and III malocclusions. The aim of this study is to review the literature, assessing the methods used to obtain an effective molar distalization anchored by miniscrews.Keywords: Skeletal anchorage – Mini-implants – Orthodontic miniscrews

ABSTRACT It is undeniable that extra-alveolar mini-implants anchorage has revolutionized Orthodontics. Correspondingly, the proper understanding of mini-implants biomechanics allowed to broaden the range of dental movements as never seen before in clinical practice. However, in order to produce better treatments, especially regarding the effects in occlusal plane, it is important to be aware of the numerous possibilities of applying force systems based on skeletal anchorage. Thus, this paper aims to address, by means of clinical cases, the application of biomechanics concepts that are extremely relevant to the proper employment of extra-alveolar mini-implants.

In conventional Class II treatment, distalisation of the maxillary arch usually requires multiple phases of tooth movement during which anchorage loss can occur. In order to solve this issue, a rational and simple technique has been developed. Instead of using intraoral distalisers along with palatal mini-implants, Ni-Ti superelastic loops are used to obtain molar distalisation while buccal interradicular miniscrews (BIM), preferably placed between the roots of upper premolars, supply the necessary anchorage. Once the distalisation of molars and second premolars is performed, miniscrews are placed between the roots of first molars and second premolars after removing the previous miniscrews. Elastic chains or tie-backs, which go from the new miniscrews to the hooks of a 0.019×0.025-inch stainless-steel archwire, produce the retraction of incisors, canines and first premolars with optimal control of anchorage. Clinical cases are shown to illustrate the technique.

Recent studies indicate there is some disagreement concerning the interpretation and clinical utility of the Type V Bekesy pattern. Bekesy tracings obtained over the past six years from a sample of clinical cases were analyzed and a definition was established for the Type V pattern. This definition was applied to Bekesy tracings obtained from normal listeners, hypoacusics, and pseudohypoacusics. The Type V pattern was found frequently among pseudohypoacusics and only rarely among other individuals.
