Large mandibular bone defects can be difficult to treat in dogs, with a high risk of mal or non-union due to instability and risk of infection. This case report article describes the use of autologous clotted blood mixed with biphasic calcium phosphate micoparticles to fill a defect non-union fracture and promote bone regeneration in a dog in a two-stage surgical approach. This new method was designed and tried in a dog with a chronic, unstable mandibular fracture associated with a large sequestrum. A first intervention allowed debridement of the lesion, then the oral wound and oral vestibule were reconstructed in two layers. Four weeks later a second stage surgery allowed placement of a pre-contoured maxillofacial plate to bridge the defect, which was filled with a blood/ biphasic calcium phosphate compound implant. Cone-beam computerized tomography was used prior to the initial surgery for pre-operative planning and 3-D printing of a mandibular template for plate contouring. It was subsequently used for follow-up of the healing process, using a bone-density measurement tool to assess bone regeneration. The defect healed within 6 months with effective filling of the defect and restoration of alveolar ridge continuity. The functional and cosmetic results were considered excellent. Cone beam Computed Tomography was found useful to monitor the healing process, bone regrowth and remodeling. This case report is to serve as a pilot trial for a prospective study.
