| ［摘要］ 目的 分析有压板和无压板两种类型的导航工具对数字化种植导板手术备孔精度的影响。方法 回顾性分析有压板导航工具和无压板导航工具植入的16例患者，共40颗种植体，每种工具各20颗。术前通过六维牙种植设计软件对种植体位点进行三维设计，术后拍摄CT并在六维牙种植设计软件中进行重建，与术前方案进行配准后导入Rhino软件中，对术前术后种植体颈部中心点距离偏差、底部中心点距离偏差、颈部垂直向偏差和角度偏差进行测量比较。结果 有压板导航工具植入的种植体颈部中心点距离偏差均值为1.243 mm，底部中心点距离偏差均值为1.911 mm，颈部垂直向偏差均值为1.201 mm，角度偏差均值为5.077°，无压板导航工具植入的种植体依次为0.696 mm、1.167 mm、0.449 mm、4.582°。结论 无压板的导航工具备孔精度高于有压板的导航工具备孔精度。 |

| ［Abstract］ Objective To analyze the effects of two types of surgical guide kits with drilling key and without drilling key on the surgical accuracy of digital guided dental implant surgery. Methods A retrospective analysis was performed on 16 patients with 40 implants of two types of surgical guide kits with drilling key and without drilling key in total, and 20 implants for each type. The three-dimensional(3D) positions of the implants were designed by 6D Dental Planning Software. After the operation, computed tomography(CT) was taken and the implants were reconstructed by the 6D Dental Planning Software. After rectification with the preoperative model, the implants were imported into Rhino software to obtain the distance deviation of implant neck center point, the distance deviation of implant bottom center point, the vertical deviation of neck and the angle deviation before and after the operation, and the preoperative and postoperative deviations were compared. Results In the implants with drilling key, the mean distance deviation of implant neck center point was 1.243 mm; the mean distance deviation of implant bottom center point was 1.911 mm; the mean vertical deviation of neck was 1.201 mm, and the mean angle deviation in angulation was 5.077°. In the implants without drilling key, the mean distance deviation of implant neck center point was 0.696 mm; the mean distance deviation of implant bottom center point was 1.167 mm; the mean vertical deviation of neck was 0.449 mm, and the mean angle deviation in angulation was 4.582°. Conclusion The accuracy of guided implant surgery operated by the guide tool without drilling key is higher than that of the tool with drilling key. |
