【摘要】：目的:研究3D导板指引下采用精准微创的方法,疏通钙化根管治疗根尖周炎的临床新技术。方法:针对根管不通的前牙患者拍摄CBCT,收集CBCT数据并结合口内三维扫描数据,三维重建确定牙根方向,精确定位根管的长度及方向。进行3D导板的设计并打印,超声工作尖在3D导板的指引下去除根管内钙化物质,疏通根管,镍钛根管预备、超声冲洗结合热牙胶充填进行根管治疗。结果:使用3D导板引导,钙化根管得以精准疏通,X线检查显示疏通根管沿固有根管方向走行,根管壁破坏小,根管治疗得以顺利实施。结论:CBCT测量结合3D打印导板可以安全精准的定位根管方向和深度,微创进行根管治疗,对于钙化根管治疗具有较好的指导性。
[Abstract]:Objective: to study a new clinical technique for the treatment of periapical periodontitis with calcified root canal under the guidance of 3D guide plate. Three-dimensional reconstruction was used to determine the direction of the root canal and to locate the length and direction of the root canal accurately. The 3D guide plate was designed and printed. The ultrasonic working tip was guided by the 3D guide plate to remove the calcified substance in the root canal, dredge the root canal and prepare the nickel-titanium root canal. Results: guided by 3D guide plate, the calcified root canal could be precisely dredged by X-ray examination, which showed that the root canal went along the direction of the inherent root canal, and the damage of root canal wall was small. ConclusionConclusion the ratio CBCT measurement combined with 3D printing guide plate can safely and accurately locate the direction and depth of root canal and minimally invasive root canal therapy, which has good guidance for calcified root canal therapy.
