A 7-year-old spayed female Welsh corgi presented with a mass of the skull. The mass was diagnosed as multilobular bone tumor and surgically removed. To treat a large bone defect after the tumor removal, custom-made artificial bone fabricated by a 3-dimensional ink-jet printer was implanted in the defect. Follow-up computed tomography evaluation was performed for 4.3 years. The implant was well integrated with the skull and had covered the large bone defect during the follow-up period. Gradual degradation of the implant began 6 weeks after surgery. It provides an additional option for the treatment of large bone defect.

Bone grafts are essential for promoting bone healing in some orthopedic cases, and synthetic bone materials have been widely used for bone defects. In addition, osteoinductive proteins such as bone morphogenetic protein and fibroblast growth factor promote osteoblast differentiation and proliferation. The combination of these factors is very useful clinically for promoting bone healing. In this study, we report the use of synthetic bone materials and osteoinductive proteins to repair bone defects in two dogs.
