摘要
目的：对牙周炎患者行上颌窦内提升术同期植入种植体的临床效果进行评价。方法：收集2007年7月～2013年7月因上颌后牙缺失的慢性牙周炎患者25例，行单纯上颌窦内提升术并同期植入种植体43枚，修复后随访观察6～70个月。结果：观察期内种植体总留存率97．67％，窦底提升高度≥6mm者种植体留存率为94．44％。42枚种植体成功负载，无松动或脱落。所有牙周炎患者在随访期内均未发生上颌窦炎症，曲面断层片显示种植体根尖部与窦底之间可见新骨生成，种植体周围骨整合良好，窦底提升后上颌窦底至牙槽嵴顶的骨量明显增加。种植体周围软组织健康，无炎症，牙周探诊龈沟出血指数（SBI）0—1度。结论：对剩余骨高度不足的慢性牙周炎患者，上颌窦内提升术同期植入种植体可获得满意的临床效果。
Objective： To evaluate the clinical effects of osteotome sinus floor elevation （OSFE） and simultaneous implant placement in partially edentulous patients due to chronic periodontitis. Method： Forty-three implants were placed in the posterior maxilla in 25 partially edentulous patients due to chronic periodontitis with the technique of OSFE and simulta- neous implant placement. The follow-up period was 6 to 70 months. Result： The overall survival rate was 97.67 % and the survival rate of sinus lift height ≥6mm was 94.44 % during the study period. Forty-two out of the 43 implants were clinically stable and loaded .There were no loose or lost, no clinical complaint of the maxillary sinus inflammation. Panoramic X-ray exam showed well osseointegration, and no obvious bone resorption was found in peri -implant surrounding. There was new bone formation found in maxillary sinus elevation even on without bone transplantation cases. The average of sulcus bleeding index around the implants was 0-1. Conclusion： To atrophic edentulous posterior maxillary region in patients with periodontitis, OSFE and simultaneously implant placement can achieve satisfactory clinical effect.
