Bite force on single as opposed to all maxillary front teeth
Scandinavian Journal of Dental Research
|December 1, 1994
Summary
Maximal clenching force significantly increases with more teeth engaged. This study found that biting with multiple teeth generates greater force than single-tooth biting, with no impact on tactile sensitivity.
Area of Science:
- Dental Science
- Biomechanics
- Oral Physiology
Background:
- Maximal clenching force is a critical indicator of oral function.
- Understanding the relationship between tooth count and bite force is essential for dental health and prosthodontics.
Purpose of the Study:
- To investigate the correlation between the number of teeth engaged and maximal incisal clenching force.
- To assess the impact of maximal bite force testing on tooth tactile sensibility.
Main Methods:
- Ten healthy female dental students participated in the study.
- Maximal incisal forces were measured using custom acrylic splints engaging either single anterior teeth or multiple anterior teeth (13-23 and 33-43).
- Tactile sensibility of a specific tooth (11) and its antagonists was evaluated before and after force measurements.
Main Results:
- A highly significant difference in maximal clenching force was observed between single-tooth and multiple-tooth biting conditions.
- Bite force demonstrated a significant increase during successive biting trials, regardless of the number of teeth engaged.
- Maximal bite force trials did not alter the tactile sensibility of tooth 11 or its antagonists.
Conclusions:
- Engaging multiple teeth significantly enhances maximal clenching force compared to single-tooth biting.
- Repeated maximal biting efforts lead to increased bite force, suggesting a potential learning or adaptation effect.
- Maximal incisal force testing does not compromise the tactile sensory function of the tested teeth.
