Avaliação de técnica cirúrgica parendodôntica: apicectomia em 90º, retrocavitação com ultra-som e retrobturação com MTA
Abstract
Técnicas consagradas como apicectomia por broca em 45 graus, retrocavidade com broca de aço esférica e retrobturação com amálgama tem sido gradativamente substituídas por novas seqüências de procedimentos que aumentam os benefícios cirúrgicos, melhorando o prognóstico clínico. A metodologia utilizada neste artigo encontra-se embasada em revisão bibliográfica e aplicação laboratorial. Isto possibilitou identificar inúmeras vantagens no uso da apicectomia em 90 graus, retrocavidade com ultra-som e retrobturação com Odontology Mineral Trioxide Aggregate (MTA), nas cirurgias.
UNITERMOS: apicectomia; ultra-som; MTA.
ABSTRACT
The Dentistry technological innovations have been modifying the endodontics surgery paradigms. The most conventional techniques, as apical resection for drill in 45° angle, and retrocavitation with spherical steel drill and root-end filling with amalgam, are being gradually substituted for new sequences of procedures that aim to increase the surgical benefits, improving the clinical prognostic. The methodology applied in this paper is based on literature review and laboratorial research. The results shows a number of advantages in using procedures as the resection in 90 degrees, ultrasonic preparation of root-end cavities and root-end filling with Mineral Trioxide Aggregate (MTA) in the endodontics surgeries.
UNITERMS: apicoectomy; ultrasonics; MTA.
