摘　　要：目的 采用螺旋CT和曲面断层片对种植牙患者术前的颌骨条件进行评估,评价两种检查方法的优劣.方法 收集牙缺失要求种植牙修复患者80例,对患者进行术前CT扫描和曲面断层检查,挑选适合做种植牙的患者并依据螺旋CT将获得的数据信息进行颌骨重建指导种植牙的设计和植入.结果 术前螺旋CT检查可以更准确的挑选出适合种植牙修复的患者,更精确地显示出缺牙区的骨质情况.结论 螺旋CT三维重建可以在术前精确的显示出牙种植体植入区颌骨的骨质情况和临近的重要解剖结构,有效的辅助种植义齿的设计和牙种植体植入方向及深度的判定,较曲面断层具有明显的优越性.Objective To evaluate the value of spiral CT and panoramic radiographs in preoperative assessment the jaw condition of patients for dental implantation.Methods 80 patients required dental implant restoration,these patients were Manned by CT and panoramic radiographs in preoperative,then selected suitable patients for dental implant restoration,reconstructed the jaw based on spiral CT data and guided the dental implant design and implanration.Results The spiral CT examination could be more accurate selection criteria for the patients needed dental implant restoration and more accurately showed the situation of edentulous ridge bone.Conclusion The reconstructed of three-dimensional imaging of spiral CT could precisely show the bone situation in the jaw needed dental implant and the important anatomic structures,could effectively assist denture design and the direction and depth of dental implants.was more superiority than panoramic radiographs.
