CLINICAL CASE N° 2 (figures 6-8)
A 62 year-old male patient having no general health problem. He smoked 1 pack of cigarettes per day since 30 years. The mandible presented an infiltrating squamous cell carcinoma in the anterior lingual floor which had to be surgically treated with anterior hemiglossectomy and interrupting excision of the entire dentate mandible (while maintaining the mandibular angles). A fibula graft was planned to rebuild the mandible. The surgery and the implant-supported reconstruction were performed. Surgery and implant reconstruction were carried out immediately in order to anticipate the surgical and prosthetic rehabilitation of the patient. A fixed implant-supported prosthesis was considered for optimal arch restoration. The 3D planning allowed a surgically-driven implant placement (CAD-CAM drilling and implant guides) for 6 intrafibular implants (Zimmer® (Warsaw, Indiana) (TSVB10, 3.5 or 4.1 x 16mm), and the positioning of the fibula graft.
