A New Approach for Minimally Invasive Access to Severely Calcified Anterior Teeth Using the Guided Endodontics Technique.

This article describes an endodontic treatment technique performed through a new minimally invasive approach that leads to no tooth damage at the incisal edge and uses cone-beam computed tomographic (CBCT) imaging and 3-dimensional guides. A 26-year-old patient presented with pain in the anterior region of the maxilla and reported having suffered dental trauma 13 years prior. Radiographic examination exhibited no visible root canal on tooth # 9 with a slight thickening in the apical periodontal ligament space.
