However, not all mandibulardefects can be surgically reconstructed, due tolocal or systemic factors. Oral rehabilitation withconventional removable dentures is often insufficient. In order to provide predictable supportand 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 over denture in two non-reconstructed patients with similar mandibular defect, but different etiology, as wellas different denture design and different outcomein terms of success and patient satisfaction. In the first case, the defect was caused by surgicaltreatment of cancer, which was followed byradiotherapy and prosthodontic treatment withan implant-supported mandibular overdentureanchored with a bar. In another case, the damage was due to a suicide attempt. This was initiallyfollowed 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, maxillo mandibular relationships, the consistency of mandibular movement and the denture design play an important role as wellTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaSlovensko zdravniško društvo
