| 目的 对Simplant牙种植导板进行改良设计，评价其临床应用效果。方法 利用Simplant软件设计种植导板，3Shape软件进行三维镂空改良设计，并铸造转化为改良金属导板。应用改良导板实施20例种植手术，植入31颗种植体，并评价种植体术后与术前三维设计的位置偏差：颈部偏移量、尖部偏移量与偏移角度，评估导板的固位、视野及散热性。结果 31颗种植体平均颈部、尖部偏移量分别为（1.5±1.1）mm和（2.1±0.8）mm，平均偏移角度（4±1.5）°，经t检验，差异无统计学意义（P>0.05）。改良导板临床应用固位稳定、视野清晰、散热良好。结论 改良式种植导板精度较高、利于散热、应用方便，具有辅助临床手术的价值。 |

| Objective To improve dental implant surgical template of Simplant, and evaluate the accuracy of modified template by deviation between the actual and planning implant positions. Methods Design the template by Simplant, modify the template by 3Shape, and then print the resin template and transform the modified template by casting. Evaluate the deviations of implant position at the shoulder and apex, the projected deviation of angle, stability, surgery vision and heat conduction of template from 31 implants on 20 patients. Results With the modified template, the deviations of the implant position at the shoulder and apex, and the deviation of angle were 1.5±1.1mm, 2.1±0.8mm, and 4±1.5°. The modified template is stable, with good vision and heat conduction. Conclusions This modified CAD/CAM template can support surgical implant with high accuracy, good cooling and flexible operation. |
