Impact of pivoting bite tip on bite force measurement tests

Area of Science:

• Biomedical Engineering
• Dental Science
• Biomechanics

Background:

• Bite force measurement is crucial for evaluating the stomatognathic system's function, particularly in an aging population.
• Existing gnathodynamometer designs may lack optimal patient comfort and operator precision.
• Improving bite test methodology is essential for accurate functional assessments and quality of life evaluations.

Purpose of the Study:

• To present a novel gnathodynamometer design featuring a pivoting bite tip.
• To enhance patient comfort, operator precision, and ease of use during bite force testing.
• To evaluate the efficacy of the pivoting bite tip in dental bite force measurements.

Main Methods:

• A 180° pivoting bite tip was evaluated in a double-blind trial with senior dental students.
• Tests were conducted on incisors (tooth 11) and molars (tooth 16).
• Participants and operators rated comfort and precision using a 0-10 scale.

Main Results:

• No significant difference in comfort or precision was observed for incisor tests.
• A statistically significant improvement in comfort and precision was found for molar tests (P < 0.01).
• The pivoting bite tip demonstrated enhanced performance in the molar region.

Conclusions:

• The pivoting bite tip improved participant comfort and operator precision in molar bite force tests.
• The gnathodynamometer design shows promise for improving bite force testing in both incisor and molar regions.
• Further research is needed to determine the impact of these improvements on mean and maximum bite force measurements.
