Abstract(s)
Objetivo: A presente revisão pretende analisar e comparar a velocidade de distalização
do molar superior, em diferentes aparelhos ortodônticos, através de uma revisão
sistemática.
Materiais e Métodos: Foi realizada uma pesquisa bibliográfica eletrónica, e utilizados
critérios seletivos de inclusão nomeadamente: dentição com pelo menos o primeiro
molar permanente erupcionado, valores cefalométricos antes e depois do estudo, e
população entre os 9 e os 16 anos. Só os estudos clínicos retrospectivos, estudos clínicos
controlados e estudos clínicos randomizados, entraram nesta revisão sistemática. Os
relatos de casos clínicos, anomalias craniofaciais, revisões sistemáticas e meta-análise,
pacientes com doença periodontal, métodos de aceleração do movimento, distalização
em bloco da arcada dentária, foram excluídos.
Resultados: Dos oito dispositivos analisados, o First Class foi o que conseguiu uma
maior distalização do primeiro molar superior (4 mm), em menor tempo de tratamento
(quatro meses), no entanto com um elevado grau de inclinação molar.
Conclusão: A evidência científica encontrada na realização desta revisão sugere que o
aparelho distalizador de Gelgor et al. grupo 2, que utiliza um mini-implante na pré
maxila, acrílico circundante ao mesmo e o vetor de força palatino, é o eleito para este
tipo de movimento. Mais estudos deverão ser efetuados, com os mesmos planos de
referência e utilizando as mesmas variáveis para os diferentes dispositivos, recorrendo a
uma avaliação tridimensional.
Objective: The present review intends to analyze and compare the distalization speed of the upper molar, in the different orthodontic appliances, through a systematic review. Materials and Methods: An electronic bibliographic search was performed, and selective inclusion criterias were used, namely: dentition with at least the first erupted permanent molar, cephalometric values before and after the study, and population between 9 and 16 years old. Only retrospective clinical studies, controlled clinical studies and randomized clinical studies entered this systematic review. Clinical case reports, craniofacial anomalies, systematic reviews and meta-analysis, patients with periodontal disease, methods of accelerating movement, massive distalization of the dental arch were excluded. Results: Among the eight devices, the First Class was the one that achieved the greatest distalization of the upper first molar (4 mm), in less time of treatment (four months), however with an elevated degree of molar inclination. Conclusion: The scientific evidence found in this review suggests that the distalizer device by Gelgor et al., that uses a mini-implant in the premaxilla, acrylic surrounding it and a palatal force vector, is the chosen one for this type of movement. Further studies should be carried out, using the same reference plans and using the same variables for the different devices, using a three-dimensional evaluation.
