Long-term results of augmentation of the atrophic mandible.

This is a report on the long term results of Visor-Sandwich Osteotomy. From 1979 until now, more than 60 patients with extreme atrophy of the mandible were operated on. All patients underwent bone transplantation from the iliac crest, and, about half a year later, mouth-floor and vestibuloplasties with skin grafting were done. 29 patients were selected who had been operated on by the same oral surgeon. The purpose of this investigation was: a. to investigate the number of sensitivity disturbances in the mental nerve area; b. to get an impression of the overall results; and c. to determine the rate of resorption of the mandible after osteotomy, bone grafting and vestibuloplasty, which were carried out 1.5 to 5 years previously.
