Previous issue date: 2009-02-04 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / The maintenance of masticatory function is especially important for patients who wear complete dentures due to the limitations of this type of prosthesis. Thus, the bilateral balanced occlusion (BBO) is used to achieve, besides other advantages, greater masticatory efficiency. However, analyzing critically the literature, it is observed that there is not enough scientific evidence that support the BBO as the most appropriate occlusal concept in complete dentures. This way, the purpose of the present study was to verify if complete dentures wearers with BBO present better masticatory efficiency and capacity
than those with canine guidance (CG). A double-blind controlled crossover clinical trial was conducted. The sample was made of 24 completely edentulous patients. The subjects wore sets of complete dentures with both occlusal concepts for equal periods of 3 months.
Objective data were collected through the masticatory efficiency test, performed by the colorimetric method, in which capsules of a synthetic material enclosing fuchsine-
containing granules were used. Subjective data were recorded by patient?s ratings of their chewing function, which is the masticatory ability. No significant statistical difference was found for masticatory efficiency (p=0,0952) and masticatory ability (x2=0,5711/ p=0,4498)
between the two occlusal concepts studied, as well as there was no correlation between these two variables (p=0,2985). Based on these results, it seems reasonable to use CG for the setup of complete dentures, since it is an easier and quicker technical procedure, until that future researches can come to complement this question / A manuten??o da fun??o mastigat?ria tem import?ncia especial em pacientes portadores de pr?tese total devido ?s limita??es inerentes a esse tipo de pr?tese. Nesse
contexto, a oclus?o balanceada bilateral (OBB) ? empregada com o intuito de obter-se, entre outras vantagens, uma maior efici?ncia mastigat?ria. Entretanto, analisando-se a literatura criticamente, observa-se que n?o existem evid?ncias cient?ficas suficientes que
suportem a aplica??o da OBB como conceito oclusal ideal em pr?tese total. Assim, o presente trabalho teve o objetivo de verificar se pacientes portadores de pr?tese total dupla com OBB apresentam maior efici?ncia e capacidade mastigat?ria que aqueles com desoclus?o com guia canino (DGC). Com esse intuito, realizou-se um ensaio cl?nico controlado duplo-cego do tipo crossover. A amostra foi composta de 24 pacientes portadores de pr?tese total dupla, onde todos fizeram uso de ambos os conceitos oclusais por per?odos iguais de 3 meses. A fun??o mastigat?ria foi avaliada clinicamente atrav?s
da efici?ncia mastigat?ria, onde se empregou o m?todo colorim?trico com o uso de c?psulas mastigat?rias, e pela capacidade mastigat?ria, relativa ao grau de satisfa??o.
N?o se encontrou diferen?a estat?stica significativa para a efici?ncia (p=0,0952) e a capacidade mastigat?ria (x2
=0,5711/ p=0,4498) entre os dois grupos estudados, bem como n?o foi observada nenhuma rela??o entre essas duas vari?veis (p=0,2985). Dessa forma, parece sensato o emprego da DGC nos movimentos exc?ntricos em pr?tese total, por ser este um procedimento mais simples e r?pido, at? que futuras pesquisas venham a
complementar qual o conceito oclusal ideal em pr?tese total
