A device for testing the durability and exploitation reliability of dental prostheses

Area of Science:

• Biomaterials Engineering
• Dental Prosthodontics
• Mechanical Testing

Background:

• Current dental prosthesis testing lacks comprehensive simulation of oral conditions.
• Existing devices have limitations in assessing friction, motion kinematics, and environmental influences.

Purpose of the Study:

• To design and develop a novel stand for evaluating the operational stability of dental prostheses.
• To address the limitations of existing testing equipment by incorporating oral cavity environmental factors and realistic motion kinematics.
• To create a versatile testing platform for complete dental prosthetic structures.

Main Methods:

• Literature review of existing prosthesis testing devices.
• Development of an original stand design based on author's concepts.
• Analysis of limitations in friction node testing, motion kinematics, and environmental impact assessment.

Main Results:

• Simplified design schematics of the developed testing stand were generated.
• The stand's design accommodates various dental prosthesis sizes.
• The system allows for the application of loads at randomly selected points on the prostheses.

Conclusions:

• Experimental verification confirmed the achievement of research objectives.
• The developed stand successfully enables testing of diverse prosthetic structures.
• The device facilitates comprehensive evaluation of dental prosthesis stability under simulated oral conditions.
