目的：了解计算机种植导板在斜向种植手术的应用情况。方法2011年2月—2014年1月之间，通过常规上下颌骨CT扫描，经计算机辅助制作软件建模，对13例上颌骨骨量不足种植病例，进行一定角度下斜向植入种植体而不需要进行上颌窦提升手术。共植入21颗种植体，均利用快速成型技术加工出个体化种植模板，并应用于该种植手术中。结果在计算机种植导板的帮助下进行了斜向植牙，种植体植入术前设计位置实现了种植体的精确植入，能够在修复时与对颌牙形成良好的咬合关系，与术前设计方案基本一致。结论该文利用计算机种植导板在进行上颌骨斜向植牙而非提升手术，可以很好的完成骨量不足区域的种植手术的定位及导向功能，是一种相对安全的选择性方案。%Objective To explore the application of computer-assisted implant guide in inclined implant surgery .Methods From February 2011 to January 2014,after conventional CT scanning of maxillary and mandible ,the software modeling was made with the as-sistance of computer ,and 13 cases with inadequate bone mass in maxillary were selected to undergo an inclined implant surgery .Indi-vidualized implant models were made by rapid prototyping for 21 implants in total and were applied in the surgery .Results Inclined implant surgeries were operated by using computer-assisted implant guide .The accurate implantation was accomplished thanks to preop-erative designs for the location of implants so that favorable occlusion was formed ,which was consistent with the preoperative designing scheme.Conclusions Instead of sinus elevation ,inclined implant surgery using computer-assistant implant guide is a relatively safe choice for the location and guiding of surgeries in the area where bone mass is inadequate .
