  • In this report, a case is presented in which resected mandible was reconstructed immediately with vascularized bone graft and adjunctive implantation of osseointegrated dental implants. The primary was central odontogenic myxoma of mandible extending from symphysis to the left condylar neck. The hemimandibulectomy defect was restored with free fibular flap. Three months after 1st surgery, the transplant received five $IMZ^{(R)}$ implants. The masticatory function was restored with the implant borne denture. The result including facial appearance was very satisfactory.

  • Loss of continuity of the mandible destroys the balance and symmetry of mandibular function, leading to altered mandibular movements and deviation of the residual fragment towards the resected side. Apart from deviation, other dysfunctions include difficulty in swallowing, speech, mandibular movements, mastication, and respiration are accompanied. In general, surgical reconstruction is considered first then proceeds to the prosthetic restorations. However, patients with systemic disease such as BRONJ (Bisphosphonate related osteonecrosis of the Jaw), surgical reconstruction may be limited. Thus, the prosthetic restoration remains as the only resort. Numerous prosthetic methods are employed to minimize deviation and to improve masticatory efficiency, function and esthetics. If a removable partial denture is the selected treatment modality, maximum stability of the partial denture base may be accomplished with a functional impression procedure by means of eliminating lateral and horizontal forces caused by the functional movements of the lips, cheeks and tongue. Also, Twin occlusion is used to obtain a favorable occlusal relationship and check support for esthetics. The purpose of this case report is to demonstrate how neutral zone impression technique and twin occlusion scheme were applied to restore a hemi-mandiblectomy patient with BRONJ syndrome to achieve satisfactory results in functional and esthetic aspects.
