摘要： 目的:通过CBCT扫描以及计算机辅助设计、制造技术(CAD/CAM)制作口腔种植导板,然后评价该类导板在手术备孔中的精度。方法:利用口腔锥形束CT(ConeBeamCT,CBCT)扫描6位患者的上下颌骨,获得颌骨数据后,利用医学种植软件和快速成型技术制作CAD/CAM导板。依靠导板植入24颗种植体,术后再次拍摄CBCT,配准术前、术后数据,测量种植体在预期位置上的偏离值。结果:种植体植入后颈部偏离值为(1.03±0.55) mm,顶端偏离值(1.19±0.56) mm,角度偏离值 (3.12±2.64)°。结论:CAD/CAM种植导板能够有效地将设计方案转移到手术过程中,降低手术风险,获得较高精度,有较高的临床应用价值。

Abstract: Objective: To evaluate the accuracy of the CAD/CAM implant template based on CBCT data for dental implants preparation. Methods: Jaws from 6 patients were scanned using cone beam computed tomography (CBCT). The CT data was used to fabricated CAD/CAM implant templates. Twenty-four implants were inserted in edentulous patients using CAD/CAM implant templates. All patients had CBCT scanning again after operation. Preoperative and postoperative computed tomographic images were compared, and the deviations between actual and planned implants were measured. Results: With the help of CAD/CAM implant templates, the neck deviation of the implant was 1.03±0.55mm, apical deviation was 1.19±0.56mm, and axis deviation was 3.12±2.64°. Conclusion: The CAD/CAM implant template can accurately transfer the preoperative design, reduce the risk of operation, and is worth for clinical use.
