三维影像配合手术导板在口腔种植中的美学应用

目的:探讨三维放射影像配合3D手术导板于人工种植的临床美学研究及其应用特点。方法:随机选择10例患者,术前三维影像学予以检查并设计方案,在3D手术导权引导下行不翻瓣口腔牙种植术,术后再以三维放射影像与原软件手术计划比较,以测量其角度的误差。结果:和传统植牙方法相比,术前三维影像学检查设计,并辅以3D手术导板引导植牙术后植体角度误差<1～3°,术后行12个月跟踪调查,未见种植体有松动和脱落,X线片显示未发现种植体周围有阴影存在,种植后修复效果良好,美观效果佳。结论:三维影像医学检查设计辅以3D手术导板引导牙种植术手术简便,易于美观且效果好,手术创伤小,患者不适感相对小,值得临床借鉴和参考。

Clinical aesthetic application of three dimensional images with surgical guide template in oral implantation

Objective In this study,10 patients was randomly selected to evaluate clinical aesthetic research of three-dimensional radiological images with the 3d surgical guides do artificial Dental Implants as well as the application characteristics. Methods The patients will to be inspected by three-dimensional images and designed the program before implant surgery,and guided flapless implant surgery by 3D surgical guides,postoperative three-dimensional radiographic images were compared with the original surgical planning, in order to measure the angle discrepancy of implant. Results Compared with the method of traditional dental implant,three-dimensional imaging tests before surgery that supplemented by the 3D surgical guides guided dental implant made the angle discrepancy of postoperative implant was less than 1 ～3 degrees.There were no implants mobility or lost during a follow-up around 12 months,X-ray film showed that no shadow was existed around the implant, therefore the Repairing effect and the aesthetic effect were very good after implant surgery. Conclusion The use of three dimensional images inspection and design that supplemented with 3 d surgical guide template make the dental implant surgery was simpler, easier, smaller surgical trauma and the patient＇s discomfort was relatively small;moreover the effect was better than before;it is worth for dental surgeon to clinical lean and reference.
