Optical aspect of deformation analysis in the bone-denture complex

Area of Science:

• Biomechanical Engineering
• Materials Science
• Orthodontics

Background:

• Mandible deformation under load is critical for understanding oral function and designing dental prosthetics.
• Accurate measurement of strain fields is essential for validating biomechanical models.

Purpose of the Study:

• To quantify mandible model deformation using a stereometric measuring system.
• To evaluate the effectiveness of the ARAMIS 3D image correlation system for strain analysis.

Main Methods:

• Utilized the ARAMIS three-dimensional image correlation system with synchronized digital stereo cameras.
• Applied varying loads to mandible models to measure full-field strain.
• Recorded deformation data, focusing on peak values and specific anatomical regions.

Main Results:

• The ARAMIS system successfully captured complete strain fields during load application.
• Maximum deformation of 625 micrometers was recorded near the lower second premolar under a 500 N force.
• The system demonstrated its capability to accurately register and measure deformation trends.

Conclusions:

• Stereometric measurement systems, like ARAMIS, are valuable tools for modern biomechanical research.
• This methodology provides precise data for understanding mandible behavior under stress.
• The findings highlight the system's potential for applications in dental and orthodontic research.
