Prefabricated Implant Treatment for an Aneurysmal Bone Cyst of the Mandible: A Case Report and Review of the Literature

Aneurysmal bone cyst (ABC) is a benign, destructive and expanding bone lesion. Most commonly it is found in long bones and around 2-12% of cases are seen in head and neck region. ABC is an expansile osteolytic lesion, which consists of blood filled spaces separated by connective tissue septa and multinucleated giant cells. Aspiration, radiographic examination, and cross-sectional scans assist in ruling out other odontogenic or non-odontogenic pathologies and also help in locating the lesion. This paper documents case report of Aneurysmal bone cyst in a 28-year-old male patient. This article presents clinical diagnosis, investigations, and surgical management of the lesion, along with a review of literature. There are various treatment options for the management of aneurysmal bone cyst. This case management consisted of osteotomy and mandibular reinforcement with prefabricated implants using stereolithography models followed by histopathological examination, which further confirmed the diagnosis. This lesion has rare occurrence and should be considered in differential diagnosis for osteolytic and expansile swelling in mandibular region.
