[Dental rehabilitation using osseointegrated implants: treatment of oro-maxillo-facial cancer. A preliminary study of 7 cases]. / La réhabilitation dentaire par fixtures ostéo-intégrables: traitement des cancers oro-maxillo-faciaux. Etude préliminaire de 7 cas.

Edentulism is often reported after treatment for malignancy of oral cavity. The resulting deformities from loss of teeth and bone create a "social invalid" with difficulties in articulation and mastication. Prosthetic rehabilitation was difficult because of two problems: the risk of osteoradionecrosis development and local anatomic modifications. The introduction of osseointegrated implants improved results of oromandibular reconstruction. A preliminary report of nineteen Branemark implants of seven patients is reported here. Implants have been in place and functioning for a period of one to four years. No major complication occurred and osseointegration permitted good oral rehabilitation. Placement of osseointegrated implants in osteomyocutaneous flaps and in irradiated bone is discussed.

[Sequelae of condylar fractures in the experience of the department and that of medical expertise]. / Les séquelles des fractures condyliennes à travers l'éxpérience du service et l'expertise médicale.

Statistical analysis was conducted on findings in 104 cases of fractures in the condylar region and 25 patients examined to determine degree of incapacity as a result of these types of fracture. Data obtained illustrated the adverse effects of ascending ramus shortening, and the improvement obtained after surgical restoration of its height whenever this was indicated. Long-term follow up surveillance is also necessary after high subcondylar fractures with impaction of the ascending ramus because of the risk of external temporomandibular ankylosis.
