摘要:
目的　评价3D打印机制作铸造金属导航支架的临床应用效果及其精确性。方法　对22例患者的上下颌骨进行锥形束计算机断层扫描（CBCT）得到医学数字影像和通讯（DICOM）数据并导入Simplant软件中，利用软件的导航技术模拟出种植体最佳的植入位置及深度，将数据导入3D设计软件（3Dtool）进行三维重建，利用3D打印机制作种植导航支架，在导航支架的引导下进行精确的种植，术后再次进行CT扫描，术前、术后CT数据进行配准，测量实际种植体与模拟种植体的误差值。结果　22例牙缺失患者中，4例使用黏膜支持种植导板（支抗钉固位式），10例使用牙支持种植导板，8例使用支抗-牙联合支持种植导板。种植导板固位力合适，取戴方便，38枚种植体在完成种植后均获得良好的位置，种植体肩部、根尖部、角度与原设计的误差分别为（1.30±0.25）mm、（1.26±0.21）mm、（2.04±0.54）°。结论　通过个性化铸造金属种植导航支架植入人工牙根，可以提高植入位点的精确度，同时导航支架制作周期短、术中视野开阔和冷却效果确定，术后恢复快，患者满意度更高。
Abstract:
Objective　To evaluate the clinical application effects and accuracy of the casting metal navigation scaffold on 3D printing technology.Methods　Twenty-two patients′ upper and lower jaw received cone beam computerized tomography (CBCT) scan,then the digital imaging and communications in medicine (DI-COM) data was imported into Simplant software.The navigation technology of Simplant software was used to simulate the optimum position and depth of the implant,then the data were transferred into 3Dtool for three-dimensional reconstruction.3D printing technology was used to manufacture the implanting navigation scaffold,which was used to guide precise implantation. The deviation between planned implants and actual implants was measured by registering of pre- and post-operative computer tomography images.Results　Among 22 cases with missing tooth,4 cases were treated with implant template of mucosa support (anchorage implat retention),10 cases were treated with template of tooth support and another 8 cases were treated with template of anchorage combined tooth support.The implant template had sufficient retention which was easy to place and remove on the teeth.Thirty-eighty implants were implanted accurately.The entry deviations of theimplant was（1.30±0.25）mm and apical deviation was （1.26±0.21）mm and the axis deviation was （2.04±0.54）°.Conclusion　Personalized casting metal implanting navigation scaffold can improve the accuracy of the implant site,and as well as it has short operating cycle,well cooling,a good surgical vision and rapid recovery after operation and higher patient satisfaction.
