Single tooth bite forces in healthy young adults.

Area of Science:

• Biomedical Engineering
• Dental Research
• Biomechanics

Background:

• Accurate assessment of single tooth bite forces is crucial for evaluating dental implant outcomes.
• Understanding variations in bite force is essential for restorative dentistry and prosthodontics.

Purpose of the Study:

• To quantify maximum bite force on healthy single teeth in young adults.
• To investigate the influence of tooth position, dental arch side, and sex on bite force.
• To establish reference values for dental forces.

Main Methods:

• A novel single tooth strain-gauge bite transducer was employed.
• Maximum bite force was measured in 52 healthy young adults (36 men, 16 women).
• Analysis of Variance (ANOVA) was used to assess differences based on tooth position, side, and sex.

Main Results:

• No significant differences in bite force were observed between the left and right sides of the dental arch.
• Incisors demonstrated the lowest bite force (40-48% of maximum), while first molars exhibited the highest.
• Bite forces were significantly greater in men than in women (P < 0.002).
• A monotonic increase in bite force was recorded along the dental arch towards the molars (P < 0.0001).

Conclusions:

• Sex and tooth position significantly influence maximum bite force.
• The findings provide valuable reference data for comparing dental forces in patient populations undergoing oral rehabilitation.
• These data can aid in the assessment of single implant success and overall dental biomechanics.
