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.
