Endodontia guiada por tecnologia: uma revisão crítica sobre as aplicações de guias endodônticos para a prática clínica

Abstract

INTRODUCTION: Endodontic therapy aims to preserve teeth in the oral cavity through decontamination and three-dimensional sealing of the root canals. However, treatment failures may require retreatment to ensure complete eradication of microorganisms. Considering the associated challenges, such as the removal of filling materials and access to calcified canals, new technologies have been explored to optimize procedures. Three-dimensional printed endodontic guides, or “GEs,” represent an innovation that enables more precise and minimally invasive retreatments. This technique combines Cone-Beam Computed Tomography (CBCT), intraoral scanning, and 3D printing to plan and perform guided access, reducing the loss of dental structure. OBJECTIVES: This study reviews the literature on the application of endodontic guides in retreatment, analyzing their evolution, clinical effectiveness, biomechanical impacts, and feasibility. METHODOLOGY: This is a narrative literature review. The search was carried out through scientific databases, applying rigorous selection criteria. CONCLUSION: The association of digital technologies, such as GEs and CBCT, with magnification resources represents a significant advance in the management of calcified canals, ensuring greater safety, dental preservation, and clinical predictability. However, the definitive validation of their benefits requires controlled clinical trials to support the standardization of protocols.
