Descripción de la cirugía endodóntica guiada con navegación estática

Abstract

Background: Static navigation assisted guided surgery is a minimally invasive technique that directs the operator to obtain a more precise insertion pathway and achieve faster wound healing, with a significantly higher success rate than the traditional apical surgery technique. Objective: To describe the steps to perform static navigation assisted surgery with guide ring and trephine based on scientific evidence. Search methods: A search strategy was designed from 2011 to 2021 for articles published in PubMed, Epistemonikos, Cochrane, Web Of Sciencie and Embase. The selection criteria were studies on the guided endodontic surgery procedure published in the last 10 years, systematic reviews, in vitro studies, case reports and case series. The evaluation of methodological quality, risk of bias and data extraction were performed independently and in duplicate. The results were expressed using the PRISMA guide and the tool developed for case reports and in vitro studies. Results: Eleven studies were obtained for review where the steps required in static navigation assisted surgery were described, consisting of intraoral scanning or silicone impression for obtaining the triangular language standard (STL) file or polygonal file (PLY), tomography to obtain the digital image and communication in medicine (DICOM) files, then the coupling of the 2 files in a software, where first the DICOM is imported and then the STL or PLY, then the creation, export and import of the guide to start the surgical procedure. Conclusions: Guided osteotomy and apicoectomy with a 3D printed surgical template decreases operative time, reduces postoperative complications, and improves healing. Although 3D fabrication of surgical templates is a more time-consuming process, the duration of the surgical procedure is reduced, benefiting patient comfort and safety.
