The provisional prosthesis is a prerequisite for prosthodontic rehabilitation. The purpose of this technique was to register facial and intraoral scans predictably. A 3D virtual patient was created through facial scans, intraoral scans, digital face-bow transfer, and digital cross-articulation technique. This virtual patient allowed predictable positioning of intraoral scans to a virtual articulator by using digital face-bow transfer. The resulting virtual patient facilitated the design of definitive prostheses following a facially generated treatment planning principle. In addition, the virtual articulator was used to improve occlusal design on the definitive prostheses and reduce the need for intraoral adjustment.
临时义齿是修复体制作的前提,本技术的目的是为了可预测地记录面部和口内扫描。通过面部扫描、口内扫描、数字面弓转移和数字交叉咬合技术创建 3D 虚拟患者。通过数字面弓转移,该虚拟患者允许将口内扫描可预测地定位到虚拟咬合架上。制作完成的虚拟患者有助于根据面型生成的治疗计划原则设计最终义齿。此外,虚拟咬合架可用于改善最终义齿的咬合设计,并减少口内调整的需要。
