ABSTRACT

PURPOSE:

To evaluate the rehabilitation of edentulous mandibles with osseous integrated implants in immediate loading, using models in reverse planning.

METHODS:

A prospective study was performed on 14 patients with a total of 56 implants placed. It was proposed a technique for the rehabilitation of edentulous mandible with osseous integrated implants of immediate loading, using anatomical replicas derived from computerized tomography scan linked to the rapid prototyping technique of stereolithography in reverse planning, elaborating the definitive fixed prosthesis, with rigid union of the implants on the same day. The patients' mandible models were divided in two groups. In the first one, there were patients with edentulous mandible models and with models elaborated after exodontics procedures (Group 1). In the second (Group 2), patients with dentulous mandible models, which allow an evaluation of difficulty in the surgery.

RESULTS:

The proposed technique using anatomical models for the personalization of mandibles in immediate loading had 100 percent of less difficulty in the adaptation of the surgery guide while the dentulous models had 83,3 percent of more difficulty.

CONCLUSION:

The proposed technique using the mandible models in the rehabilitation of mandibles is feasible.
RESUMO

OBJETIVO:

Avaliar a reabilitação de mandíbulas edêntulas com implantes osseointegrados, em função imediata, utilizando biomodelos no planejamento inverso.

MÉTODOS:

Foi realizado um estudo prospectivo em 14 pacientes com um total de 56 implantes colocados, em que foi proposta uma técnica de reabilitação de mandíbulas edêntulas com implantes osseointegrados, em função imediata, utilizando biomodelos, confeccionados a partir dos dados da tomografia computadorizada, no planejamento inverso, confeccionando a prótese fixa final, com união rígida dos implantes, no mesmo dia. Os biomodelos dos pacientes foram divididos em dois grupos. Um deles composto pelos pacientes com biomodelos edêntulos e aqueles confeccionados após exodontia (grupo 1). O outro (grupo 2) composto pelos pacientes com biomodelos dentados, sendo avaliada a dificuldade do procedimento, quanto a cirurgia.

RESULTADOS:

A técnica proposta do uso da prototipagem biomédica na função imediata nas mandíbulas com biomodelos edêntulos teve 100,0 por cento de menor dificuldade na adaptação da guia cirúrgica, enquanto os biomodelos dentados apresentaram 83,3 por cento de maior dificuldade.

CONCLUSÃO:

O biomodelo no planejamento inverso de reabilitações orais teve 100,0 por cento de menor dificuldade em comparação com os protótipos dentados 83,3 por cento de maior dificuldade.
