本研究的目的是评估立体光刻模板的准确性，套筒结构纳入设计，计算机引导的牙种植体插入部分缺牙患者。材料和方法。使用立体光刻手术模板将65个种植体植入25名连续患者体内。手术后，取数字印模，并使用检查工具软件测量植入物在入口点、顶点和角度偏差处的3D不准确性。使用Mann-Whitney U检验比较上颌和下颌手术导板之间的准确性。p值
The aim of this study was to evaluate the accuracy of a stereolithographic template, with sleeve structure incorporated into the design, for computer-guided dental implant insertion in partially edentulous patients. Materials and Methods. Sixty-five implants were placed in twenty-five consecutive patients with a stereolithographic surgical template. After surgery, digital impression was taken and 3D inaccuracy of implants position at entry point, apex, and angle deviation was measured using an inspection tool software. Mann-Whitney U test was used to compare accuracy between maxillary and mandibular surgical guides. A p value
