Computer-Aided Design (CAD) allows for patient-specific dental devices using 3D digitization of clinical situations. Mechanical dimensioning is crucial to avoid therapeutic failure; however, current CAD software focuses solely on geometry lacking mechanical behavior modeling. Thus, patient-specific dental device design often remains empirical and dependent on clinical intuition. The team has shown that combining 3D digitization, CAD, and mechanical simulation can optimise dental restoration. Moving forward, the team aims to develop mechanical models of patient-specific devices that reflect clinical realities. Supported by of a characterization platform, new mechanical testing protocols enhance model accuracy. The objectives are:

1. i) to optimise prosthesis design
2. ii) to develop mechanical virtual twin of prosthesis-tooth assembly for integration into CAD software.

The expected outcome is the creation of Computer-Aided Engineering (CAE) tools that incorporate material properties, functional requirements, and tissue-bonding interfaces to optimize dental device design automatically.
