Abstracts on this page have been chosen and edited by Dr Trevor Watts ABSTRACT Five-year implant survival was 89% for immediate insertion into grafts, and 95% for a 2-stage procedure. MAIN

Yerit KC, Posch M _et al_. _J Clin Oral Impl Res_ 2004; 15: 693–699 In 36 patients with severe maxillary alveolar atrophy, horseshoe Le Fort I osteotomy was performed with iliac crest graft

interposition. In 12 patients, 100 implants were placed at the same operation (Group A), and in another 23 patients, 224 implants were placed 6-9 months later (Group B). Implant-supported

overdentures were provided for all patients. In Group A, patients were monitored for a mean 109 months (range 61-141), and in Group B, for 60 months (0.5-136). Group A 2-year failure-free

rate was 96%, and Group B, 95%; respective 5-year rates were 97% and 91% (between group _P_ = 0.57). In Group A, 14 implants were lost in 6 patients, and in Group B, 15 in 11. Eight implants

were lost at the stage 2 surgery through failure of osseointegration, and the remaining 21 were lost between 1 and 9 yrs after implantation for a variety of reasons. There were minor

complications of sinusitis in 3 patients, one of them 6 years after surgery. Subsequently, 26 patients answered a questionnaire; all were satisfied with the procedure, with a few minor

complaints. RIGHTS AND PERMISSIONS Reprints and permissions ABOUT THIS ARTICLE CITE THIS ARTICLE Long-term implant survival in the grafted maxilla: results of a 12-year retrospective study.
