Accuracy of 3-Dimensional Printed Surgical Guides with Varying Trephine Port Lengths in Simulated Endodontic Microsurgery
Abstract
Endodontic microsurgery (EMS) is an effective way of treating persistent apical periodontitis. Surgical endodontics is a treatment modality that requires skill and experience. The various technical facets of EMS render this procedure challenging for a novice to perform freehand. EMS requires the clinician to estimate the site of perforation, angulation, and depth of osteotomy based on preoperative radiographs or cone beam computed tomography images (CBCT). Maintaining a conservative, precise osteotomy along with an accurate root-end resection may be challenging in areas of the mouth with limited access. Targeted endodontic microsurgery (TEMS) facilitates EMS in challenging scenarios. It utilizes CBCT and three-dimensional (3D) technology to print a surgical guide that directs a trephine bur to the apical root end, performing osteotomy and root resection simultaneously. Each TEMS guide is fabricated with a port, comparable to an implant guide sleeve, which accommodates the trephine bur and directs it to the precise location of the surgical target. Currently, there are no studies on the specific parameters of TEMS guides, specifically with how short the port can be while maintaining an accurate path for the trephine bur.
