Virtual Surgical Planning and 3D-Printed Guided Biopsy of Bilateral Lesions in the Mandible: A Case Report

Abstract

Purpose: To report the use of virtual surgical planning and a 3D printed drill guide for the biopsy of mandibular lesions. Case report: A 38-year-old woman presented with two bilateral lesions in the mandibular body, in close proximity to the inferior alveolar nerve and the molar roots. An incisional biopsy was planned with coDiagnostiX software using the cone beam computed tomography DICOM files and a cast model that had been digitalized using a bench scanner (7series, Dental Wings, Quebec, Canada). A tooth-supported drill guide was produced by 3D printing with digital light processing technology (Moonray S, Sprintray, CA, USA). The surgical procedure was performed under local anesthesia. No complications were observed intraoperatively or during postoperative recovery. Conclusion: The use of an intraoperative surgical 3D-printed drill guide enables a smaller surgical procedure and more precise bone biopsies.

Three‐dimensional printed surgical guides for keratoma removal in horses using computed tomography or magnetic resonance imaging‐based segmentation

“…Accurate targeting and the use of 3D printed guides to assist with surgical procedures have been used in several species including horses 8–10 . However, the use of 3D printed guides for planning and removing keratomas of the equine hoof has not previously been reported.…”

“…4 Accurate targeting and the use of 3D printed guides to assist with surgical procedures have been used in several species including horses. [8][9][10] However, the use of 3D printed guides for planning and removing keratomas of the equine hoof has not previously been reported. The objective of this case series is to report the technique, surgical approach and postoperative features in 5 horses with keratomas, diagnosed using CT or MRI and treated via a 3D printed guide assisted keratoma removal.…”
