ABSTRACT
ABSTRACT

Objective:

To introduce newly structured and developed orofacial myofunctional therapy (OFMFT) protocols named Bio-Exercise (BioEx), and evaluate the treatment effect of this method, using lateral cephalometric analysis on malocclusion with low tongue posture in young patients.

Methods:

A retrospective preliminary study was performed using orthodontic records from 28 patients (mean age of 8.41±1.45-year-old, 13 males, 15 females) treated with BioEx therapy using tongue elevators for 18.14±9.04 months (range 6 to 37 months). Pretreatment (T0) and post-BioEx therapy (T1) lateral cephalograms were subsequently analyzed for tongue posture changes by linear, anteroposterior and vertical measurements. The data were analyzed by paired t-test, considering a 5% significance level.

Results:

The tongue length (TGL) and tongue height (TGH) increased statistically significant between T0 and T1. The decrease of the dorsum of the tongue perpendicular to the palatal plane (Td-PP value) was statistically significant. The increase of the tip of the tongue perpendicular to the pterygomaxillary vertical line (TT-PMV) was not statistically significant.

Conclusions:

These preliminary cephalometric results indicate that BioEx can be an effective OFMFT modality in increasing the tonicity of the tongue muscles to establish more normalized tongue position at rest.
RESUMO
RESUMO

Objetivo:

Introduzir protocolos de terapia miofuncional orofacial (TMO) recém-estruturados e desenvolvidos, denominados Bio-Exercise (BioEx), e avaliar o efeito do tratamento com esse método, usando análise cefalométrica em radiografias laterais de jovens com má oclusão e postura baixa da língua.

Métodos:

Foi realizado um estudo preliminar retrospectivo com registros ortodônticos de 28 pacientes (idade média de 8,41±1,45 anos, 13 homens, 15 mulheres) tratados com terapia BioEx usando elevadores de língua por 18,14±9,04 meses (intervalo 6 a 37 meses). As radiografias cefalométricas laterais pré-tratamento (T0) e pós-tratamento com BioEx (T1) foram analisadas quanto às alterações na postura da língua, por meio de medidas lineares, anteroposteriores e verticais. Os dados foram analisados pelo teste t pareado, considerando-se um nível de significância de 5%.

Resultados:

O comprimento da língua (CL) e a altura da língua (AL) aumentaram entre T0 e T1, com significância estatística. A diminuição do dorso da língua perpendicular ao plano palatino (valor Td-PP) foi estatisticamente significativa. O aumento da ponta da língua perpendicular à linha vertical pterigomaxilar (PL-PMV) não foi estatisticamente significativo.

Conclusões:

Esses resultados cefalométricos preliminares indicam que o BioEx pode ser uma modalidade de TMO eficaz no aumento da tonicidade dos músculos da língua, para estabelecer uma postura de língua adequada em repouso.
