Summary
This study introduces a robotic dental simulator to test dental material wear. A novel compliance module and force transducer accurately measure biting forces, crucial for understanding dental component failure.
Area of Science:
- Biomaterials Science
- Robotics Engineering
- Dental Mechanics
Background:
- Dental restorations face significant wear and failure due to occlusal forces.
- Accurate simulation of human chewing forces is essential for material testing.
Purpose of the Study:
- To develop and validate a robotic periphery for a six-degrees-of-freedom dental simulator.
- To simulate and measure forces during dental material wear testing.
Main Methods:
- Reverse engineering of human jaws to create artificial mandible and maxilla.
- Integration of a compliance module and strain gauge force transducer in the robotic system.
- Measurement of jaw characteristic indicators like Spee and Monson curves.
Main Results:
- The robotic periphery successfully emulated human-like jaw occlusion.
- The integrated strain gauge force transducer accurately sensed small changes in biting forces.
- The system is capable of simulating wear on various dental components.
Conclusions:
- The developed robotic system provides a reliable platform for testing dental material durability.
- Accurate force measurement is key to understanding and preventing dental component failure.
- This simulation aids in the development of more resilient dental materials and restorations.
