Oral Reconstruction of Hemi-Mandibulectomy Patients by Implant Overdenture: Report of Two Cases

Introduction: Loss of mandibular continuity, jaw deviation, extensive freely movable soft tissues, and difficulty in mastication, swallowing, and speech are the results of hemi-mandibulectomy, which adversely affect the patients’ quality of life. Management of such patients by fixed or removable prostheses is a complex and challenging approach as the type of prosthesis is a determinant factor in successful rehabilitation. Case Presentation: The present report describes prosthetic rehabilitation of two patients who underwent hemi-mandibulectomy due to osteosarcoma. After clinical and paraclinical evaluations and multidisciplinary consultations, it was decided to use implant-supported removable overdenture with stud attachments and an open-structure framework for them. Results: Jaw reconstruction and dental rehabilitation of hemi-mandibulectomy patients are complicated procedures. However, with regard to developments in dental science, the clinicians have different options to fulfill the esthetic and functional demands of such patients. The current paper showed that implant-supported removable prostheses with stud attachments can successfully rehabilitate the hemi-mandibulectomy defects when the interocclusal space is limited and achieving the implants’ parallelism is a challenge due to the nature of hemi-mandibulectomy procedure.
