However, the technique is still used in the clinical area for a surgical plan or education prior to surgery. Thus, we report a case of reconstruction after tumor removal surgery with the use of a 3D-printed scaffold. A 12-year-old female mixed dog had a left caudal maxillary mass. Based on computed tomography images, a defect was confirmed on the maxillary bone due to the oral mass, and a surgical plan was designed to remove the oral mass and graft the 3D printed scaffold. Customized polycaprolactone/ beta-tracalciumphosphate (PCL/β-TCP) scaffold was fabricated using the micro-extrusion-based 3D printer. In the operation, after the removal of the oral mass, the scaffold was grafted onto the defect site. At follow-up, 8 months after surgery, the result was successful without any special problems in the periodic CT scans and oral examinations. This case is believed to be the first case of reconstruction by using a 3D printed scaffold in the maxillary bone defect, and this 3D printing technique is thought to be very helpful for veterinary patients with bone defects and several other diseases.
