上颌后牙区种植的临床研究

目的:总结上颌后牙种植修复的特点和方法。方法:我科自2006年4月至2009年4月期间采用常规种植或加骨挤压、上颌窦内提升、上颌窦外提升、使用短种植体技术、倾斜种植技术等方法,共完成上颌后牙种植病例85例,174颗种植体,术后随访平均时间为5年8个月(5⁸年)。结果:无上颌窦炎症发生,2颗脱落,余牙X线复查显示种植体周围无阴影,成功率98.85%。结论:上颌后牙缺失的病例,应用CBCT观察缺牙区骨质骨量情况,结合患者对种植手术的依从性,综合考虑,分别采用不同种植方法,可以减少创伤,降低费用,增加成功率。

A prospective study on the dental implants in the maxillary posterior

Objective: To summarize the characteristics and methods of dental implants in the maxillary posterior. Methods: From April 2006 to April 2009,a total of 174 implants were consecutively placed within 85 patients in stomatology department,using the methods of common implant,minimally invasive bone extrusion,open maxillary sinus floor elevation,close maxillary sinus floor elevation,short implant,tilted implant and so on. The mean time of follow up was 5 years and 8months( 5-8years). Results: There were no clinical complaint of the maxillary sinus area,and X-ray exam showed well osseointegration in the other implants postoperatively. The cumulative success rate was 98. 85%. Conclusion: According to CBCT,bone mass in edentulous ridge and compliance of patient towards the implant surgery in missing posterior teeth cases,using the different implanting methods could lead to less trauma,less costs and higher success rate.
