“…It provides more accurate and detailed information about the anatomical structures of a root canal system, which has a positive impact on outcomes by improving predictability [21] . Within surgical endodontics, it plays an important role as it helps to measure the distance between the cortical plate and the apex, the position of the roots within the bone and the proximity of vital structures [22] . CBCT imaging allows locating the visible part of the root canal and planning the access route to the root canal system while preserving the cervical dentin [23] .…”

Introduction:In 2016, a new approach to endodontics using CAD/CAM printed guides or splints emerged, mostly in pieces with pulp obliteration. Objective:To analyze the literature on some current endodontic techniques for the treatment of pulp obliteration, such as static guided endodontics, dynamic guided endodontics, and guided endodontic microsurgery. Methodology: PubMed, SCOPUS and Google Scholar databases were reviewed to find recent articles published on guided endodontics with the following keywords: "pulp obliteration", "CBCT", "static guided endodontics", "dynamic guided endodontics" and "guided endodontic microsurgery". Results: Pulp obliteration is the narrowing of the dental pulp space, which is caused by extrinsic and intrinsic factors. CBCT helps to measure the path of the canal in the dental roots, in order to be able to perform the appropriate accesses in endodontics. Static-guided endodontics, also called Endo Guide, uses 3D printed directional guides made with CBCT and CAD/CAM. Dynamic guided endodontics combines images that are reproduced in real time, guiding access and angulation. Microsurgery is performed when there is a failure in root canal therapy, its success rate has been increasing thanks to the use of CBCT that helps to link the other techniques using templates that predict the procedure. Conclusions: Pulp obliteration causes pulp sclerosis and necrosis which at some point will require root canal treatment, currently different techniques can be used such as static guided endodontics, dynamic guided endodontics, microsurgery in which they have to go hand in hand with the use of CBCT for planning, the choice of these depends on the complexity of the case.

We aimed to design a novel three-dimensional (3D) printed surgical guide and evaluate its accuracy in assisting endodontic microsurgeries. A new 3D printed surgical guide was designed by computer-aided design and computer-aided manufacturing (CAD/CAM) technology and applied to 7 patients who underwent endodontic microsurgeries of upper anterior teeth from 2020.01 to 2020.12 as the experimental group. 7 patients who suffered from endodontic microsurgeries operated by the same surgeon without using the surgical guide from 2019.01 to 2019.12 were selected as the control group. Cone beam computed tomography (CBCT) was performed more than 12 months after operation, and the accuracy of apical resection was compared between the two groups. The accuracy of the microsurgery focused on the length and angle of the root apical resection. In the study, CBCT data and oral digital scanning data were used to reconstruct 3D models of periapical lesions with soft and hard tissue information, based on which we designed the new 3D printed surgical guides. The guides were successfully applied to the apectomy in endodontic microsurgeries. The deviation of the apical resection length of the experimental group (0.467 ± 0.146 mm) was better than that of the control group (1.743 ± 0.122 mm) (P < 0.0001), and the deviation of the apical resection angle of the experimental group (9.711 ± 3.593°) was significantly less than that of the control group (22.400 ± 3.362°) (P < 0.0001). The 3D-printed surgical guide could effectively guide endodontic microsurgery and improve its accuracy by fixing both the position and the angle of apectomy. The new type of surgical guide could accurately localize the root apex and guide the apical resection.
