Summary
Intense chewing significantly increases the inter-occlusal rest space (free-way space), even after a month of training. This effect was observed immediately after chewing and persisted, unlike daily training which showed no significant changes in chewing subjects.
Area of Science:
- Dentistry
- Biomechanics
- Physiology
Background:
- The inter-occlusal rest space, or free-way space, is a critical measurement in dentistry.
- Understanding factors that influence this space is important for oral health and function.
Purpose of the Study:
- To investigate the effects of short-term intense chewing and long-term daily chewing on the inter-occlusal rest space.
- To determine if a training period alters the response to intense chewing.
Main Methods:
- 15 healthy subjects participated in a month-long daily chewing training program for one hour.
- Inter-occlusal rest space was measured before and after chewing sessions.
- A control group (8 subjects) did not perform chewing exercises.
Main Results:
- Short periods of intense chewing (30 minutes) doubled the mean inter-occlusal distance.
- This increase occurred regardless of whether subjects had undergone the training period.
- No significant changes in inter-occlusal rest space were observed in subjects undergoing daily training or in the control group.
Conclusions:
- Short-term, intense chewing significantly impacts the inter-occlusal rest space.
- A month of daily chewing training did not lead to significant changes in this space.
- The findings suggest that the duration and intensity of chewing are key factors influencing the free-way space.
