Guided apicoectomy using a CAD/CAM drilling template


Sutter, Eveline; Lotz, Martin; Rechenberg, Dan-Krister; Stadlinger, Bernd; Rücker, Martin; Valdec, Silvio (2019). Guided apicoectomy using a CAD/CAM drilling template. International Journal of Computerized Dentistry, 22(4):363-369.

Abstract

AIM
Modern microsurgical techniques have increased the success rate of apicoectomy relative to that of traditional approaches. This case report introduces a novel workaround for guided apicoectomy using a patient-specific computer-aided design/computer-aided manufacturing (CAD/CAM) three-dimensional (3D)-printed template.
MATERIALS AND METHODS
Apicoectomy was performed on the mesial root of tooth 36 using template-guided trephine drilling, followed by retrograde filling with mineral trioxide aggregate (MTA). Initially, a cone beam computed tomography (CBCT) scan and an intraoral surface scan were imported into the planning software. After superimposition, virtual planning was performed to determine the exact localization for root resection. Subsequently, a tooth-supported drilling template was designed and 3D printed. Endodontic microsurgical approaches, including root-end cavity preparation and root-end filling, completed the surgical treatment.
RESULT
The apical resection was easily feasible. There were no postoperative complications. Radiological assessment after a 6-month period showed signs of reossification.
CONCLUSION
Guided apicoectomy allowed precise root resection, suggesting that this technique may be advantageous in complex anatomical situations.
