目的：介绍一种将口内扫描(IOS)、锥束CT(CBCT)和口外面部扫描(EOS)相叠加的工作流程，以创建一个三维虚拟牙科患者。材料与方法作为原则验证，将全弓IOS、术前CBCT和模拟EOS叠加到一个独特的3D数据池中。结果这一新的应用技术成功地证明了在三维静态条件下，通过iOS、CBCT和EOS图像融合来构建颅面虚拟模型的可行性。结论该应用首次结合骨骼解剖成像实现了口腔和面部表面的融合。这种新的3D叠加技术允许模拟治疗计划，探索患者的期望，并作为一种有效的沟通工具实施。下一步将是开发实时的4D运动虚拟患者。
ObjectivesThe aim of this Short Communication was to present a workflow for the superimposition of intraoral scan (IOS), cone-beam computed tomography (CBCT), and extraoral face scan (EOS) creating a 3D virtual dental patient.Material and MethodsAs a proof-of-principle, full arch IOS, preoperative CBCT, and mimic EOS were taken and superimposed to a unique 3D data pool. The connecting link between the different files was to detect existing teeth as constant landmarks in all three data sets.ResultsThis novel application technique successfully demonstrated the feasibility of building a craniofacial virtual model by image fusion of IOS, CBCT, and EOS under 3D static conditions.ConclusionsThe presented application is the first approach that realized the fusion of intraoral and facial surfaces combined with skeletal anatomy imaging. This novel 3D superimposition technique allowed the simulation of treatment planning, the exploration of the patients expectations, and the implementation as an effective communication tool. The next step will be the development of a real-time 4D virtual patient in motion.
