title: [Mandibular ridge augmentation by sandwich osteotomy and BMP-HA implantation].
abstract: In order to solve a series of problems ridge augmentation by subperiosteal implantstion, HA combined with BMP was implanted in between the two pieces of mandible produced by osteotomy. Nine adult mongrel dogs were used in this study and six patients were treated with this mathod. The specimens were examined by light microscope, scanning electron microscope in the experimental study. The results show that there are a large amount of new bone formation both within and around the combined material. The amount is increasing as the time lapsed and the new bone is connected directly with the host bone of two side. Clinical application showed that after augmentation of the atrophic alveolar ridge with this mathod, the shape and volume of the alveolar ridge were good. The retention and stability of the lower denture was improved significantly. The results showed that this method of alveolar ridge augmentation has many advantages.
