Abstract

Recently, dentistry has passed through many changes in clinical practice and technology has become more accessible and applicable. Many modern features were incorporated and have shown promising results. Consequence of these conceptual technological developments in implant treatment, the guided surgery appears as a good alternative. This technology is based on precise images of the bone anatomy, obtained by computed tomography and a personalized surgical guide that enables a flapless faster implant surgery. For many professionals it is still a distant, difficult and expensive technology. The purpose of this article is to demystify and clarify this concept, presenting a case with the placement of six dental implants for a maxillary full arch rehabilitation using a computer generated surgical guide. The guided surgery may be considered as a viable alternative for rehabilitation of edentulous jaws when provided within the correct indications.

Introduction

In last decades, the clinical dental practice has passed through many changes and technology has become more popular and applicable. Many modern features were incorporated and have shown promising results. The increase in popularity and hence demand of dental implants has encouraged the advancement in research and clinical practice, with the development in technology and improvement of the materials, bringing better clinical outcomes and patient compliance [1]. The improvement of imaging and the incorporation of computed tomography brought clearer and better anatomical structure images with real proportions and dimensions, turning the surgical planning into a more precise and accurate procedure. Through these three-dimensional images, associated to the concept of stereo lithography and CAD/CAM technology, it becomes possible to generate prototyped surgical guides with high accuracy [2].

Consequence of these conceptual and technological developments in implant treatment, the guided surgery is proposed. This technology is based on precise images of the bone anatomy, obtained by computed tomography. These images are then inserted into specific software for image manipulation, which allows the virtual implant surgery planning, where the position, diameter and its length can be planned according to the available bone [3]. The guided surgeries are indicated for the more variable types of rehabilitation with implants, including total or partial edentulous patients. In full arch rehabilitations, to obtain success with this therapy, achieving optimal aesthetic and functional results, a proper study on the selection of cases and careful planning is required [4].

Despite this, for many professionals it is still a distant, difficult and expensive technology, the purpose of this article is to demystify and clarify this concept. This study describes a clinical case with the placement of six dental implants for a full arch rehabilitation of the maxilla with the aid of a computer generated surgical guide.

Case Presentation

A 62 years old male patient, presented for treatment at the Oral &Maxillofacial Surgery and Implant Dentistry department at Federal University of Uberlandia, seeking for full arch rehabilitation of the maxilla with dental implants. After clinical evaluation and interview, it was found that the patient had no deviation from normality and had no systemic diseases that could alter the tissue integration. The patient´s upper denture was in good condition, with mandibular prostheses as antagonist (Figure 1).
