Resumo(s)
A expansão rápida da maxila para o tratamento de atresias maxilar tem sido descrita e amplamente utilizada à há algum tempo. Estudos provam que o avançar da idade piora o seu prognóstico e, como consequência disso, a expansão maxilar assistida cirurgicamente é descrita como um tratamento eficiente para pacientes com maturação das suturas craniofaciais. A Expansão maxilar assistida por mini-implantes é um método inovador, que pretende tratar as deficiências transversas da maxila, ser uma alternativa ao método cirúrgico e à expansão rápida da maxila convencional, tentando ultrapassar as limitações destes. O objetivo deste estudo teve por base a realização de uma revisão bibliográfica, através do estudo de artigos científicos disponíveis em bases de dados internacionais de forma a melhor compreender e analisar esta técnica, bem como os seus benefícios e resultados positivos em casos de pacientes com idades cronológicas mais avançadas. A expansão maxilar apoiada em mini-implantes revela ser um método promissor, contando com bons resultados a seu favor. No entanto, é necessário que mais estudos sejam feitos, de forma a alcançar um protocolo standard de instalação, ativação e avaliação da preservação dos resultados a longo prazo.
Rapid maxillary expansion for the treatment of maxillary atresia has been described and widely used for some time. Studies have shown that increasing age worsens its prognosis and, therefore, surgically assisted maxillary expansion is described as an efficient treatment for patients with craniofacial suture maturation. The maxillary expansion assisted by mini-implants is an innovative method, which intends to treat the transverse maxillary deficiencies, to be an alternative to the surgical and conventional rapid maxillary expansion method, trying to overcome the limitations of this. The objective of this study was based on a thorough investigation in order to better understand and analyze this technique, as well as its benefits and positive results in cases of patients with more advanced chronological ages. A bibliographic review was also carried out through the study of scientific articles available in international databases. The maxillary expansion supported by mini-implants proves to be a promising method, counting on good results in its favor. However, further studies are needed in order to achieve a standard protocol for the installation, activation and evaluation of the long-term preservation of results.
