Mandibular reconstruction using autogenous calvarial bone graft combined with nano-hydroxyapatite/β-tricalcium phosphate composite in a Pindborg tumor affected area.

Introduction: The use of bone grafts in dentistry following partial or total bone resections plays a crucial role in both functional and aesthetic rehabilitation. However, it is not always possible to use only xenografts or alloplastic materials; in many cases, the combination with autogenous bone is necessary due to the nature of the defect. Objective: To demonstrate that excellent outcomes can be achieved by combining alloplastic grafts with autogenous bone for large reconstructions. Case Report: In cases involving oral cysts and tumors, treatment is carefully determined based on biopsy results and complementary exams, with removal planned with safe margins to prevent recurrence. This paper presents the clinical case of a 30-year-old female patient, melanoderm, with no pre-existing conditions, who underwent a routine radiographic exam for orthodontic treatment, during which a radiolucent area was observed in the anterior mandibular region. The patient was referred to a specialized center in oral and maxillofacial surgery, where an incisional biopsy was performed. Histological analysis confirmed a Pindborg tumor. The proposed treatment was en bloc resection of the lesion, performed under general anesthesia in a hospital setting. After six months, an autogenous calvarial bone graft combined with synthetic biomaterials was performed. Conclusion: The combination of autogenous bone with alloplastic materials offers a viable and effective solution for extensive oral and maxillofacial reconstructions, ensuring structural and aesthetic rehabilitation while minimizing morbidity.
