The hemisection of affected teeth allows for the preservation of tooth structure and supporting alveolar bone, providing a chance for complete patient satisfaction. This is a viable treatment option to be considered before extracting molars with severe vertical bone loss involving a single root of a multirooted tooth. Hemisection is a respective surgical procedure indicated in multirooted teeth with grade III and IV furcation defects. This case report describes the management of a periodontally compromised mandibular molar, which received endodontic therapy, followed by hemisection, and then prosthetic rehabilitation.
