A Case of Full-mouth Rehabilitation using a Digital twin Based on Multi-source Data in a Patient with Vertical Dimension Loss due to Multiple Tooth wear and Fractures

Abstract

Abrasion, fracture, and absence of multiple teeth can occur owing to various causes. In the case of generalized wear, the inherent vertical dimension is lost, and tooth-supported or implant-supported fixed prosthetic restorations are considered as treatment alternatives. Any treatments planned on an articulator should be reproduced in patients without any errors. After verification, the final prosthesis should be fabricated. In the traditional method, this process is complicated, with theoretical and technical challenges to be overcome by practitioners. However, with the development and introduction of digital workflows as a treatment method, full-mouth rehabilitation is no longer a burdensome and challenging procedure. In this case report, full-mouth rehabilitation was performed in a 56-year-old male patient with loss of vertical dimension using a digital workflow different from the conventional method. Digital data, such as from intraoral and facial scans, CBCT, and jaw motion data, were acquired and used. Full-mouth rehabilitation was performed through case analysis, treatment plan establishment, prosthesis design, and digital manufacturing in digital twins created through the integration of various digital data.
