The success of iliac bone grafting procedures in dental implant treatment depends largely on the management to prevent graft resorption. We report a case of a 23-year-old Japanese woman who received 3 endosseous implants in the anterior maxilla with autogenous iliac bone grafting. A follow-up of the case revealed that the grafted bone was resorbed significantly in the first 6 months after grafting. However, after functional loading of the implants was started by setting the fixed partial denture, bone resorption was diminished. The grafted bone seemed to be stable for 3 years of loading. These findings suggest that mechanical loading of endosseous implants is necessary to maintain the morphology of the autogenous iliac bone graft in anterior maxilla region.
