Chirurgia implantare computer guidata: software, modelli stereolitografici e guide chirurgiche

Abstract

Objectives

Computer-guided implantology is a recent technological advance that is being used increasingly throughout the world. This article describes the clinical applications of this technology.

Materials and methods

Interactive computer processing of digital data obtained via computed tomography provides clinicians with a precise anatomical picture that can be used to tailor the prosthesis. The treatment plan is elaborated on a computer with dedicated software that positions the implants on 3-dimensional CT images. Stereolithography is used to create anatomical models and surgical guides, which allow the plan to be transferred to the patient. Implant sites were prepared with surgical instruments created specifically for computer-guided implantology. In this article we will examine a series of actual clinical cases that illustrate the main applications of this technology. The study was conducted in accordance with the principles of the Declaration of Helsinki, and informed consent was obtained from all participants.

Results and conclusions

Computer-guided technology offers enormous advantages in the 3-dimensional design of tilted implants (graftless), in the positioning of flapless implants, and in immediate-loading procedures. As a result, it is often identified with these applications. In our opinion, however, computerized planning and stereolithographic anatomical models are also highly useful during the planning and execution of reconstructive procedures in patients with severe bone atrophy. Therefore, these approaches can be applied in all clinical situations, and they always offer great advantages.
