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.

Spine Fixation

Transpedicular transdiscal screw fixation is an alternative technique used in lumbar spine fixation; however, it requires an accurate screw trajectory. The aim of this study is to design a novel 3D-printed custom drill guide and investigate its accuracy to guide the trajectory of transpedicular transdiscal (TPTD) lumbar screw fixation. Dicom images of thirty lumbar functional segment units (FSU, two segments) of L1–L4 were acquired from the PACS system in our hospital (patients who underwent a CT scan for other abdomen diseases and had normal spine anatomy) and imported into reverse design software for three-dimensional reconstructions. Images were used to print the 3D lumbar models and were imported into CAD software to design an optimal TPTD screw trajectory and a matched custom drill guide. After both the 3D printed FSU models and 3D-printed custom drill guide were prepared, the TPTD screws will be guided with a 3D-printed custom drill guide and introduced into the 3D printed FSU models. No significant statistical difference in screw trajectory angles was observed between the digital model and the 3D-printed model (P > 0.05). Our present study found that, with the help of CAD software, it is feasible to design a TPTD screw custom drill guide that could guide the accurate TPTD screw trajectory on 3D-printed lumbar models.

Arthrodesis was achieved in two foals through the placement of three 4.5 mm cortical lag screws. Two screws were placed in a standard transarticular fashion from the dorsal aspect of P1 (glide hole) to the palmar aspect of P2 (thread hole). A third transarticular lag screw was placed from the dorsal aspect of P2 (glide hole) to the palmar aspect of P1 (thread hole). Both foals were comfortable and considered suitable for light work. Crossed transarticular lag screw fixation of P1 and P2 in cases of PIPJ arthrodesis in foals is a simple and useful method offering good stability for fusion and future athletic soundness.
