本研究的目的是评估在无牙颌中使用粘膜支持的手术导板放置种植体的准确性，并确定影响准确性的因素。在术前CT图像上模拟种植体植入，并利用CAD/CAM技术制作了6个无牙颌模型和15例无牙颌患者的粘膜支持手术导板。通过比较计划图像和术后图像，计算实际植入物位置与计划位置的偏差。根据结果得出结论，粘膜支撑手术导板具有较高的准确性，骨密度和粘膜厚度可能影响准确性。(C)2013爱思唯尔有限公司保留所有权利。
This study aimed to evaluate the accuracy of implant placement with mucosa-supported surgical guides in edentulous mandibles and to determine the factors affecting accuracy. Implant placement was simulated on the preoperative CT image and mucosa-supported surgical guides were fabricated for six edentulous mandible models and 15 patients with edentulous mandibles, using CAD/CAM technology. Deviations of the actual implant position from the planned position were calculated by comparing the planned image and the postoperative image. Based on the results, it was concluded that mucosa-supported surgical guides have high accuracy and that bone density and mucosa( thickness could affect accuracy. (C) 2013 Elsevier Ltd.
