[Dental implantation at the maxilla with autologous bone transplantation]

In the Department of Maxillofacial and Oral Surgery of County Hospital of Szentes, different types of bone losses of the maxillary alveolar ridge have been treated since 1 March, 1990. The applied surgical procedures were the following: 1. 394 patients were treated with GBR technique and 567 DenTi implants were inserted for these patients. 2. In 47 cases autogenous bone grafts were harvested from mandibular cortica and 78 DenTi implants were placed. Altogether 14 implants were lost; the success rate was 97.81% in the period between 1 March, 1990 and 31 January, 2001. 3. The severely resorbed maxillary alveolar ridge was replaced by rigid autogenous bone graft harvested from the ilium or from tibia. The bone graft was fixed with implants to the recipient surface. This method was applied in 36 cases from 1 February, 1992 until 31 January, 2001. 147 DenTi implants were inserted and 7 of them were lost. The success rate was 97.28%. Our results have indicated that the dental implants had accelerated the remodelling process of the transplanted autogenous bone and the success rate of the simultaneously performed dental implants were comparable to that of the two stage procedures in which dental implants were inserted several weeks following bone grafting. Based on our long-term favourable clinical experience this technique has been proven to be an excellent method for correcting and replacing the lost maxillary alveolar ridges as well as the circumscribed alveolar bony defects.
