A retrospective study of infection after onlay graft / 中华口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the treatment and prevention of infection after alveolar crest onlay bone graft.</p><p><b>METHODS</b>From January 2006 to May 2010, 11 infection cases after onlay graft on alveolar crest were reviewed to evaluate the infection time, clinical situation, treatment measure, and therapeutic effect.</p><p><b>RESULTS</b>The infection of all 11 cases occurred about 15 days after bone graft, which showed either soft tissue fistulae or bone graft exposure in the oral cavity. Three cases failed because of persistent infection. The infection of the other 8 cases was controlled after a series of comprehensive therapy, and most of the bone graft was reserved and implant restoration finally completed.</p><p><b>CONCLUSIONS</b>After the effective and comprehensive therapy, infected bone graft can be reserved. But to ensure the survival rate of bone graft, the most important thing is to prevent infection in perioperative period.</p>
