The use of computer-aided surgical systems for dental implant bed preparation and implant placement results in an average precision within 1 mm of implant position and within 5 degrees of deviation for implant inclination. The accuracy of axis and implant position is significantly more precise with the three-dimensional surgical guide than with the free-hand method. The three-dimensional assessment of the restorative goal (radiopaque simulation of prosthesis with scanning template) allows virtual planning of implants, which enables optimized positioning of implants with surgical guide templates in oral surgery. If there is a clear indication for three-dimensional diagnostics, it should always be checked whether the data can be used as planning data for a surgical guide template, otherwise the chance for guided surgery remains unused. Since uncertainties still exist despite the use of a drilling template, it is recommended that the minimum safety distance from adjacent structures be maintained. The successful use of surgical guide templates requires comprehensive knowledge of and experience in using three-dimensional information for the virtual planning of implant position.
使用计算机辅助手术系统进行牙种植床制备和种植体植入,可使种植体位置的平均精度在1毫米以内,种植体倾斜度偏差在5度以内。与徒手操作方法相比,三维手术导板在植入轴和种植体位置的准确性方面要精确得多。对修复目标进行三维评估(使用扫描模板对假体进行不透射线模拟)可实现种植体的虚拟规划,从而能够在口腔手术中使用手术导板模板对种植体进行优化定位。如果有明确的三维诊断指征,应始终检查数据是否可作为手术导板模板的规划数据,否则引导手术的机会就会被浪费。尽管使用了钻孔模板,但不确定性仍然存在,因此建议保持与相邻结构的最小安全距离。成功使用手术导板模板需要具备全面的知识以及利用三维信息进行种植体位置虚拟规划的经验。
