Disjunção patalina apoiada em mini-implante.: Revisão de literatura

Abstract

The palatal disjunction was first described in 1861, since then it has been widely used for the correction of transverse maxillary deficiency. It is known that with the increasing of age the prognostics for the disjunction worsens Palatal expansion is a viable option for adult patients, as long as the transversal deficiency is light or moderate. The surgically assisted palatal disjunction is an efficient treatment alternative for patients in which the maturation of craniofacial sutures are in a more advanced stage. The palatal disjunction supported in mini-implants is a new proposition of treatment for the posterior cross bite, which has as objective to reach the enlargement of the superior dental arch in young adults, without causing damage to the periodontal. The technique shows good results also on the mixed and deciduous denture, including when associated with the facial mask used for Angle's bad occlusion of class III. The purpose of this paper was to study and analyze the benefits arising from this new technique and recognize the primary indications of palatal disjunction supported by mini implants as a therapeutic method. A literary revision was performed through a bibliographical research of scientific papers from national and international data base. The palatal disjunction supported by mini implants is a promising method for correcting transversal deficiencies, however it should be better studied in order to establish a protocol of installation, activation and maintenance's evaluation of the results in long term.
