摘要
目的:测试种植数字化印模的精确度,为种植数字化修复提供参考。方法:随机选取115例种植患者,待骨结合形成后放置种植转移杆,拍摄锥形束CT(CBCT),同时进行口腔扫描,制作3D打印数字化种植模型,对数字化树脂模型进行模型扫描,得到模型数据,以余留牙为参考依据,在Nobel Clinicion软件中匹配。结果:患者CBCT中种植体转移杆与数字化模型上的种植体转移杆面、冠状面、矢状面均完全匹配重叠,提示口腔内的种植体位置、方向、角度与口腔扫描制取的数字化模型上的替代体完全一致。结论:口腔扫描打印的3D数字化树脂模型完全准确,可在临床上推广运用。
PURPOSE:To evaluate the accuracy of implant digital impression,in order to provide guidance in digital implant prosthesis.METHODS:According to the requirements,115 patients undergoing implantation were randomly selected.The implantation impression cap was placed and scanned with CBCT after esteosenesis.Oral cavity was scanned to make the 3 D digital implantation model.The model data were obtained by scanning the digital resin implantation models.Based on the remaining teeth,the model data and CBCT data were matched in Nobel Clinicion software.RESULTS:The implantation impression cap in the patient’s CBCT was completely matched and overlapped with the digital model in all of the occlusal,coronal and sagittal planes,which meant that the position,direction and angle of the implantation in the oral cavity were exactly the same as those in the digital model made by oral scanning.CONCLUSIONS:3 D digital resin model of oral scanning printing is completely accurate and can be popularized and applied in clinic.
