Integrating Facial and Intraoral Scans for Digital Esthetic and Occlusal Design


Now online in the Journal of Prosthodontics, a technique report presenting a digital protocol to integrate facial and intraoral scanning, digital cross-articulation, and virtual articulator to achieve better esthetic outcomes and occlusal design for a definitive prostheses.

The traditional analog workflow for prosthesis design can be time-consuming and unpredictable. 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. This virtual patient allowed predictable positioning of intraoral scans to a virtual articulator by using digital face-bow transfer.

One limitation of this technique may be the accuracy of complete-arch intraoral scans which is still not supported by sufficient evidence. In this presented technique, intraoral scans containing premolar-to-premolar region were used. Although the clinical outcome was acceptable, further studies are needed to verify the accuracy of this method.

Overall, this digital protocol can create a 3D virtual dental patient to achieve more predictable esthetic and functional clinical outcomes for the definitive prostheses.
