目的观察上颌窦黏膜增厚对上颌窦底提升同期种植的临床效果及种植体成功率的影响.方法 2010年1月至2012年1月滨州医学院附属烟台市口腔医院种植中心就诊的16例患者(18侧),术前均无明显上颌窦炎症的临床症状及体征,锥形束CT检查上颌后牙区剩余牙槽骨高度5～8 mm,且上颌窦黏膜增厚＞2 mm行经牙槽嵴顶入路的上颌窦底提升植骨术.术前及术后6个月通过锥形束CT不同层面记录比较上颌窦黏膜厚度变化、对比上颌窦开口通畅情况,并观察种植体成功率.结果 16例患者共植入种植体18枚.锥形束CT检查14例上颌窦底提升后黏膜变薄,2例黏膜厚度增厚.术前检查上颌窦开口均通畅,术后1例开口阻塞,但无上颌窦炎临床症状发生;术后半年,种植体均获得良好的骨结合,完成种植修复,全部成功(18/18).结论上颌窦黏膜增厚不是上颌窦底提升的禁忌证.

Objective To evaluate the success rate of dental implants and the changes of sinus membrane thickness after sinus lift in cases of thickened sinus membrane.Methods Sixteen patients without maxillary sinusitis and with 5-8 mm residual alveolar bone heights were included in this study.The sinus membrane thickeness of these patients were more than 2 mm.All patients received sinus lift surgery and dental implants inserton.The changes of sinus membrane was evaluated by cone-beam CT(CBCT) presurgery and 6 months after sinus lift surgery,and the short term success rate of dental implants was also evaluated.Results A total of 18 implants from 16 subjects were inserted.The thickness of membrane was decreased in 14 cases after sinus lift and increased in 2 cases.All the orifice of maxillary sinus was unobstructed before surgery,one case was obstructed after surgery without inflammation.All the dental implants succeeded.Conclusions Sinus augmentation with thickened sinus membrane is not contraindication of sinus lift.
