Prosthetic Implant-supported Rehabilitation after Mandibular Ameloblastoma Resection: An 8-year Follow-up Case Report |Chapter 2 | Medical Science: Recent Advances and Applications Vol. 9

 

Introduction: Ameloblastomas are benign but locally invasive odontogenic tumours, most frequently located in the mandible. The gold standard treatment is the surgical resection with safety margins. Postsurgical defects generate a significant morbidity that needs reconstruction and oral rehabilitation to restore the oral functions. Dental implants are the main option for prosthetic rehabilitation. An individualised treatment plan is necessary, which requires multidisciplinary teams: maxillofacial surgeons, implantologists and prosthodontists. Case presentation: This case report describes the prosthetic rehabilitation of a 42-year-old man after mandibular ameloblastoma resection. Excision of the lesion by segmental mandibulectomy and mandibular reconstruction by microvascularized fibula flap was performed. After placement of 6 dental implants, the patient was rehabilitated with a lower hybrid prosthesis by Computer-Aided Design-Computer-Aided Manufacturing. During an 8-year and 5-month follow-up, some clinical complications were observed: peri-implant disease and explantation of one implant due to a lack of osseointegration. A strict maintenance program was performed to avoid these problems.

 

Discussion and Conclusion: An immediate reconstruction of the postoperative defect is essential to avoid aesthetic problems and functional sequelae. The functional reconstruction of large mandibular segments with microvascularized flaps and dental implants is considered the best option. Nonetheless, it is vitally important to monitor the patient closely and to follow a maintenance program to minimise peri-implant disease.
