Abstract

According to the literature, patients who have complete maxillary dentures opposing mandibular anterior natural teeth may present the combination syndrome (CS). These patients could develop the typical signs of the CS such as: overgrowth of the maxillary tuberosities, severe anterior maxillary resorption, and extrusion of the lower anterior teeth. When surgical removal of changes in the maxillary posterior ridges is asked, the subsequent prosthodontic treatment to improve oral function and aesthetics will be easier. This paper aims to present an alternative technique for presurgical prosthetic planning and surgical stent fabrication for patients with CS needing tuberoplasty. The modified surgical stent proposed was fabricated after the determination of the occlusal plane and mounting of study casts on the articulator. Adoption of the proposed stent allows more accurate determination of excessive tissue and better visualization of the area to be removed during surgery.

Keywords

Complete dentures, bone resorption, removable partial denture.

Resumo

De acordo com a literatura, pacientes que utilizam próteses totais superiores ocluindo com dentes ântero-inferiores naturais podem apresentar a síndrome da combinação (SC). Estes pacientes podem desenvolver sinais típicos da SC como: aumento das tuberosidades maxilares, reabsorção severa na região anterior da maxila, e extrusão dos dentes anteriores inferiores. Quando a remoção cirúrgica de alterações em rebordo posterior de maxila é solicitada, o tratamento protético subseqüente para melhorar função e estética será facilitado. O objetivo deste artigo é apresentar uma técnica alternativa para o planejamento protético pré-cirúrgico e para confecção de guia cirúrgico em pacientes com SC necessitando de tuberoplastia. O guia cirúrgico modificado proposto foi confeccionado após a determinação do plano oclusal e montagem dos modelos de estudo em articulador. A adoção do guia proposto permite a determinação mais precisa da quantidade de tecido excedente e melhor visualização da área a ser removida durante a cirurgia.
