牙槽嵴外置法植骨11例术后感染的回顾性研究

目的 探讨牙槽嵴外置法植骨术后继发感染的处理及预防措施.方法 回顾2006年1月至2010年5月11例牙槽嵴外置法植骨术后继发感染的病例,总结植骨术后感染出现的时间、临床表现、处理方法 以及治疗效果,并提出预防措施.结果 11例植骨术后继发感染平均出现时间为术后15 d,均表现为口腔黏膜瘘或创口裂开;其中3例因感染不愈导致植骨失败,其余8例经综合治疗后,感染均治愈,大部分移植骨块得以保存、成活,并最终完成种植修复.结论 植骨术后感染经及时有效的综合治疗,能够挽救并保存移植骨块.要保证植骨的成功,做好围手术期的感染预防至关重要.

A retrospective study of infection after onlay graft

Objective To investigate the treatment and prevention of infection after alveolar crest onlay bone graft. Methods 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 Results 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. Conclusions 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.
