目的:探讨上颌窦底内提升术在不植骨的情况下同期植入种植体的临床效果。方法:收集2008—2011年杨思医院口腔科收治的8例上颌磨牙缺失、施行上颌窦底内提升术不植骨同期植入种植体患者的临床资料,统计进行修复时和修复完成6个月后种植体的存留率,分析人工骨移植在上颌窦内提升术中所起的作用。结果:8例上颌磨牙缺失患者在不植骨的情况下,进行上颌窦底内提升术同期植入XIVE种植体14颗,修复时有1颗种植体因未形成骨结合而取出,修复完成后6个月复诊时,无种植体脱落,种植体存留率达92.9%。结论:不植骨并上颌窦底内提升同期植入种植体,6个月内能获得较高的存留率,接近文献报道的植骨并上颌窦底内提升术中种植体的存留率。
Objective: To investigate the clinical effect of maxillary sinus ascending implant in the same period without implants. Methods: Eight cases of maxillary molars were enrolled in Department of Stomatology, Yangsi Hospital from 2008 to 2011 were collected. The clinical data of patients who underwent maxillary sinus surgery with endobulbar implant without implants were collected. The data were collected for repair and repair 6 months After implants survival rate, analysis of artificial bone graft in maxillary sinus lift role played. Results: In the absence of bone graft, 8 cases of maxillary molar missing patients underwent maxillofacial anastomosis and 14 XVI implants were implanted in the same period. During the repair, one implant was removed because no bone was formed. After the repair was completed At 6 months of follow-up, no implants were shed and the implant survival rate was 92.9%. CONCLUSION: In the same period of implanting without maxillary sinus augmentation and maxillary sinus augmentation, a higher survival rate can be obtained within 6 months, which is close to the retention rate of implants in bone graft and maxillary sinus ascending.
