Endodontic Microsurgery of a Mandibular Molar Using a Dynamic Navigation System and Cortical Window Technique: Case Report

Abstract

Endodontic microsurgery (EM) of mandibular molars with a periapical lesion and intact buccal cortical bone presents a significant challenge for clinicians. This case report describes the utility of a dynamic navigation system for EM of a mandibular molar diagnosed with a previously treated tooth and symptomatic apical periodontitis, employing the "cortical window" technique using a trephine. The successful healing outcome at 21 months with cone-beam computed tomography (CBCT) was also documented.
