ABSTRACT

INTRODUCTION:

This study evaluated posteroanterior cephalograms before and after treatment and long term follow-up of Class II division 1 patients treated with bionator.

OBJECTIVE:

The objective was to demonstrate the transverse growth of maxilla and mandible during and after bionator therapy.

METHODS:

Measurement of transverse dimensions between posterior maxillary and mandibular implants, as well as the distances between the buccal, gonial and antegonial points were recorded. Measurements were analyzed at three periods T1 = before bionator therapy, T2 = after bionator therapy and T3 = 5.74 years after T2.

RESULTS:

There was statistically significant transverse increase due to growth and/or treatment for all variables, except for the distance between the anterior maxillary implants.

CONCLUSIONS:

During the study period only the anterior maxillary area did not show transverse growth.
RESUMO

INTRODUÇÃO:

esse estudo envolve a avaliação de telerradiografias posteroanteriores pré- e pós-tratamento com Bionator, bem como, em longo prazo, de pacientes Classe II divisão 1.

OBJETIVO:

o objetivo desse trabalho é demonstrar o crescimento transversal da maxila e mandíbula durante e após o uso do Bionator.

MÉTODOS:

as mensurações das distâncias transversais entre os implantes posteriores da maxila e mandíbula, bem como as das distâncias entre os pontos jugal, gônio e antigônio, foram tomadas em três tempos T1, antes da terapia com Bionator; T2, após a terapia como Bionator; e T3, 5,74 anos após T2.

RESULTADOS:

ocorreu aumento transversal estatisticamente significativo por crescimento e/ou por tratamento em todas as variáveis estudadas, com exceção da distância entre os implantes anteriores da maxila.

CONCLUSÕES:

durante o período do estudo, somente a região anterior da maxila não apresentou crescimento transversal.
