Plain-English summary
A 7-year-old French Bulldog was brought in with a tumor in the jaw that was affecting a large part of the bone. The veterinary team used a special 3D-printed template to carefully remove the tumor while preserving a crucial nerve that helps with feeling in the mouth. After surgery, they placed a custom-made plate to support the bone where it was removed. The dog recovered well, maintaining normal jaw function and feeling in the area, with no complications noted during follow-ups over the next six months.

Abstract
A 7-year-old French Bulldog presented with an acanthomatous ameloblastoma affecting approximately 30% of the right mandibular body. We utilized a patient-specific 3D-printed surgical template to perform lateral fenestration of the mandible and elevation of the inferior alveolar nerve (IAN), facilitating nerve preservation during subsequent segmental mandibulectomy. The resulting critical-sized bone defect was anatomically stabilized using a patient-specific polyetheretherketone (PEEK) bridging plate. The recovery process was uneventful, with maintained occlusion and orofacial sensitivity.Similar to cases in humans with ameloblastoma, preserving orofacial sensitivity through the preservation of the inferior alveolar nerve seems feasible in dogs. Consequently, potential negative consequences of permanent regional denervation, which are unavoidable in traditional mandibulectomy, can be avoided. Bridging the ostectomy with a PEEK plate, offering advantages such as radiolucency, absence of imaging artifacts, and a modulus of elasticity similar to bone, proved to be functional in this canine patient, with no signs of complications observed up to the latest follow-up at 6 months.
