Cirurgia guiada de implantes em área anterior e provisionalização imediata

RESUMO

A introdução da Odontologia digital redefiniu os conceitos de tratamento na Odontologia de implantes. A colocação de implantes guiada por computador tornou-se uma prática usual em busca do melhor posicionamento tridimensional. Esses avanços nas opções e modalidades de tratamento levaram a uma mudança de paradigma no fluxo de trabalho dos tratamentos cirúrgicos e restauradores. Este relato de caso apresentou um protocolo personalizado de tratamento imediato, que envolve a utilização de guia cirúrgico na região anterior de maxila confecionado após planejamento virtual prévio. Com o intuito de preservar ao máximo as estruturas do tecido mole, foi escolhida a provisionalização imediata utilizando as próprias coroas dos elementos após exodontia como parâmetro de tamanho de colo e perfil de emergência. Essa técnica facilita a obtenção de provisórios com boa qualidade estética e funcional, uma vez que a forma, a cor e o tamanho dos dentes são mantidos e corrigidos no seu melhor posicionamento na arcada. Este protocolo de tratamento também descreve um fluxo de trabalho digital e convencional integrado para reabilitações protéticas fixas suportadas por implantes, a fim de proporcionar melhor previsibilidade, menos complicações e menor invasividade.

ABSTRACT

The introduction of digital dentistry has redefined the concepts of dental implant treatment. A computer-guided implant placement became a common practice in the search for better three-dimensional positioning. These advances in treatment options have led to a paradigm shift in the workflow of surgical and restorative procedures. This case report presents a personalized protocol for immediate treatment, which involves the use of a surgical guide on the anterior maxillary region made after previous virtual planning. In order to preserve tissue structures as much as possible, the provisional immediate application was chosen as forbidden the application of crowns of the elements after extraction as parameters of neck size and loss profile. This technique facilitates the use of provisionals with good aesthetic and functional quality since the shape, color, and size of the teeth are maintained and corrected in their best position in the arch. This treatment protocol also describes a digital and conventional workflow for prosthetic rehabilitations fixed by implants, in order to provide better predictability, fewer complications, and less invasiveness.

Key words – Partially edentulous arch; Computer assisted surgery; Endosseous dental implantation; Implant-fixed dental prosthesis; Dental implants.
