[Long time results of the Sandwich-technique for mandibular alveolar ridge augmentation]

During six years twenty-five patients have been operated upon using a "sandwich technique" for mandibular alveolar ridge augmentation. This technique was advocated by Schettler in 1974. In 3 cases, autologous rib cartilage was used, in 20 Cases an autologous transplant from the iliar crest and in two cases, autologous "cialit" conserved bone chips were inserted. All transplants healed without complications and less resorption was found in all transplants at the late follow-up examinations.
