3D digital dental prosthesis design – CAD/CAM modelling of PAP chassis

3D digital dental prosthesis design, applied here to the design of a partial denture (PAP) frame, results in a rigorous metal architecture, calibrated for optimal adaptation and reliable mechanical behavior.
This STL file is the result of advanced CAD/CAM modeling integrating the support, bearing, retention and damping zones specific to high-precision PAPs.

Each structure is developed according to a digital protocol that enables fine analysis of emergences, guide lines, undercuts and functional surfaces, ensuring reproducible geometry under variable clinical conditions.

Technical specifications

• Format: high-precision STL for PAP armature

• Functional areas modeled (supports, saddles, major and minor connectors)

• Design-integrated digital undercut analysis

• Design based on patient files or digital models

• Compatible with Exocad, 3Shape and Dental Wings

Technical approach and benefits

• Optimized metal architecture for occlusal force distribution

• Connectors defined according to strict numerical modeling of guide zones

• Digital control of frame thickness and rigidity

• Precise preparation of retention zones and support points

• Immediate integration into CAD/CAM workflows (printing, casting, machining)

Software compatibility

Direct integration into :

• Exocad (Partial Framework module)

• 3Shape (Partial Design)

• Dental Wings (Dentures & Frameworks)

• SLA/DLP metallic or burnable resin printing solutions

Recommended applications

• Design of metal PAP frames
