Possibilities of Orthopedic Management of Pattern Ill Malocclusions During Growth.

Abstract

Consistently performed by most orthodontists, the orthopedic treatment involves rapid maxillary expansion (RME) combined with maxillary protraction (MP). When this treatment protocol is performed up to the intertransitional period of the mixed dentition (around 9 years of age), it allows a positive influence on the maxilla and zygomatic projection, even though there are also effects on the dentition. The ideal orthopedic treatment should influence the growth and spatial arrangement of bone bases (maxilla and mandible), so as to achieve balance and maintain it until growth completion. This goal may seem utopic, especially when the problem involves the mandible; and, assuming some genetic influence for such disorder, it is difficult to predict its future magnification during the growth period. Notwithstanding, despite the uncertain prognosis, the search for function and better facial esthetics, though temporary, should be considered This paper discusses this topic, based on the treatment progress of a youngpatient with Class III, with monitoring ofgrowth from the deciduous dentition up to adulthood, and treatment performed in two periods, using the RME and MPprotocol. Positive outcomes were achieved.
