“…Historically, 3D printed surgical guides (3DSG) have been used in endodontics with limited utility (Pinksy et al . , Byun et al , Buchgreitz et al , Strbac et al , Connert et al , Anderson et al ). Recently, targeted endodontic microsurgery (TEMS) was introduced (Giacomino et al .…”

Hawkins TK, Wealleans JA, Pratt AM, Ray JJ. Targeted endodontic microsurgery and endodontic microsurgery: a surgical simulation comparison. International Endodontic Journal, 53, 715-722, 2020.Aim To compare surgical time, bevel angle and site volumetric profiles of osteotomy and resection accomplished by targeted endodontic microsurgery (TEMS) and traditional endodontic microsurgery (EMS) in a surgical simulation model. Methodology An 80x80-mm cone beam computed tomography (CBCT) file was imported into Mimics software where artificial periapical lesions were created encompassing twelve root apices. Maxillary and mandibular models were 3D-printed. TEMS surgical guides were designed and 3D-printed for each surgical site. Three board-certified endodontists used the original CBCT to plan and perform EMS on models of six maxillary and six mandibular teeth. Next, the same endodontists performed TEMS on duplicate 3D-printed models for the same teeth. All surgeries were timed. Postoperative CBCT images of experimental models were made and imported into Amira software for measurement of bevel angle and site volumetric profiles. Paired t-tests compared the mean differences between EMS and TEMS groups. A Bonferroni correction determined data to be significant at P < 0.004. Results TEMS significantly reduced surgical time (P < 0.00001), had bevel angles more closely approaching zero degrees (P < 0.01) and had significantly less volume of over-resection (P < 0.001) and length of root resection (P < 0.01).Conclusions In this surgical simulation scenario, TEMS provided more efficient completion of osteotomy and resection, with a more appropriate root-end resection volume and bevel angle.

“…Taking this into consideration in conjunction with the results of our own previous research [10][11][12] leads us to concur with their conclusion. As reported previously, the use of 3D printing technology in endodontics is increasing 1,6) . The present findings suggest that the desktop 3D printer used in this study merits further research aimed at exploring how its application might be expanded.…”

Autotransplantation of Impacted Third Molar Using 3D Printing Technology: A Case Report

Here, we describe a case of autotransplantation of a mandibular horizontally impacted third molar using a 3-dimensional (3D) model based on limited cone-beam computed tomography (CBCT) images for diagnosis, 3D morphological evaluation, preoperative treatment planning, and surgical simulation. A 27-year-old woman visited this hospital for conservative treatment of the mandibular left second molar. Intraoral radiography and CBCT images revealed a C-shaped root canal in the mesial root, and compressive resorption of the distal root due to impingement of the crown of the horizontally impacted lower left third molar. Extraction was therefore planned. Multiple tooth-jaw bone 3D models for preoperative diagnosis were fabricated using a low-cost desktop 3D printer and surgical simulation of autotransplantation performed. The autotransplantation was then performed accordingly. Cone-beam computed tomography images and 3D models were extremely useful in obtaining a stereoscopic understanding of the morphology of the transplanted tooth and its surrounding anatomical structures. At the one-year postoperative recall, the patient was able chew with the transplanted tooth without pain, and no significant abnormalities were detected on intraoral radiographs, indicating a successful postoperative clinical course. Our experience of using 3D models fabricated based on CBCT images using a desktop 3D printer for preoperative diagnosis and surgical simulation suggests that this technique is useful in tooth autotransplantation.
