Development of computerized masticatory force measurement system

Area of Science:

• Biomedical Engineering
• Dental Research
• Biomechanics

Background:

• Assessing maximum voluntary bite force (MVBF) is crucial for evaluating masticatory function.
• Limited data exists on MVBF in the Indian population, especially after mandibular fracture treatment.

Purpose of the Study:

• To evaluate MVBF in an Indian population with normal occlusion.
• To assess changes in MVBF following treatment of mandibular angle fractures.

Main Methods:

• Development of a novel sensor fork with a modified load cell and computer-based system for dynamic bite force measurement.
• In vivo measurements were conducted at various intervals post-treatment (day, week, two months).
• Repeatability and accuracy of the measurement system were verified.

Main Results:

• The developed system demonstrated high repeatability for bite force measurements.
• A significant increase in mean bite force efficiency was observed over time after mandibular fracture treatment (p<0.05).
• Statistically significant gender differences in bite force were identified.

Conclusions:

• The developed sensor fork system offers a cost-effective and practical tool for bite force measurement.
• The findings highlight the functional recovery of masticatory forces after mandibular fracture treatment.
• Further refinement of sensor thickness could enhance the accuracy of measuring forces during mastication.
