Abstract

BACKGROUND: Segmental mandibulectomy is most often performed as part of resection of advanced squamous cell carcinoma, which involves the mandible by extension from intraoral tissues and is usually followed by reconstruction of the mandible. However, not all mandibular defects can be surgically reconstructed, due to local or systemic factors. Oral rehabilitation with conventional removable dentures is often insufficient. In order to provide predictable support and denture retention, especially in the non-reconstructed cases of segmental mandibulectomy, dental implants are indicated. Case report: The authors describe oral rehabilitation with implant-supported overdenture in two non-reconstructed patients with similar mandibular defect, but different etiology, as well as different denture design and different outcome in terms of success and patient satisfaction. In the first case, the defect was caused by surgical treatment of cancer, which was followed by radiotherapy and prosthodontic treatment with an implant-supported mandibular overdenture anchored with a bar. In another case, the damage was due to a suicide attempt. This was initially followed by the surgical treatment of the injury. Afterwards, the prosthodontic treatment with an implant-supported and conical-crown-anchored mandibular overdenture was performed.

CONCLUSIONS: The success of the prosthodontic oral rehabilitation of patients with segmental mandibulectomy depends on many factors. The size of the defect and the condition of the remaining hard and soft tissues, which are affected by radiotherapy, are crucial. The etiology of the defect, the opposing jaw status, maxillomandibular relationships, the consistency of mandibular movement and the denture design play an important role as well.
