Implant Rehabilitation After a Partial Resection of the Mandible Resulting from Submandibular Gland Malignancy—A Case Report
Adenoid cystic carcinoma of the submandibular gland is a relatively rare malignancy of the oral and maxillofacial region. It is an insidious disease characterized by regional spread, perineural invasion, and potential distant metastases. Because of the aggressive nature of this lesion, it is often impossible to completely excise the tumor, necessitating combination therapy of surgery and radiation. The consequences of surgical ablation coupled with radiation treatment can result in complex considerations in the dental care of these patients. This case report outlines a patient who has recovered from multiple surgeries and radiation therapy, requiring mandibular dental implant reconstruction for a return to normal comfort and function.
