[Pre-implantation apposition grafts for edentuous anterior maxillary. Retrospective study of 36 patients].
BACKGROUND
Apposition grafting is a method of choice for reconstruction of the anterior maxillary. The purpose of this work was to evaluate the success rate, the degree of bone resorption and the osteointegration of these grafts.


METHODS
We reviewed retrospectively 36 cases of pre-maxillary bone apposition in patients operated from 1998 to 2002. Autografts were used for all patients. The harvesting site was parietal for 24 patients, intraoral for 8 and iliac for 4.


RESULTS
There was two graft failures. The success rate was 94.5%. Partial resorption with effect on implantation was noted in 3 patients. Eighty implants were inserted successfully in 234 grafted sites with on average 2.4 implants per graft. Three implants were removed. Implant survival was 96.2%.


CONCLUSIONS
This study demonstrated that the premaxillary apposition technique using autologous grafts provides sufficient bone volume to enable optimal implant insertion and stability.
