The 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.
As 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.
This 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.
The 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.
本简短通讯的目的是展示一种用于叠加口腔内扫描(IOS)、锥形束计算机断层扫描(CBCT)和口腔外面部扫描(EOS)以创建三维虚拟牙科患者的工作流程。
作为原理验证,获取全牙弓IOS、术前CBCT和模拟EOS并叠加到一个独特的三维数据集。不同文件之间的连接环节是将现存牙齿作为所有三个数据集中的恒定标志点进行检测。
这种新型应用技术成功证明了在三维静态条件下通过IOS、CBCT和EOS的图像融合构建颅面虚拟模型的可行性。
所展示的应用是实现口腔和面部表面融合并结合骨骼解剖成像的首个方法。这种新型三维叠加技术允许模拟治疗计划、探索患者期望并作为一种有效的沟通工具加以应用。下一步将是开发动态实时四维虚拟患者。
