Accuracy of Guided Endodontics in Posterior Teeth

The purpose of this ex vivo study was to determine the accuracy template-based guided endodontics for access cavity preparation and root canal detection in posterior teeth. First, three maxillary four mandibular models were constructed using 67 premolars molars, with a total number 135 main canals. Cone beam computed tomography (CBCT) three-dimensional 3D surface scans each model performed matched order plan design templates virtually. Template-guided then tooth, followed by postoperative CBCT scanning. Deviations between planned prepared cavities measured after superimposition pre- scans, they analyzed descriptive multivariate statistics. All canals (135/135) detected utilizing endodontics. mean angle deviation 1.4 degrees, deviations at tip base bur 0.24–0.31 mm 0.26–0.29 mm, respectively. This demonstrated that is an accurate predictable method endodontic
