Summary
Head posture significantly impacts dental occlusion. Changes in head position alter occlusal contacts, affecting occlusion and disclusion times during dynamic jaw movements, crucial for restorative dentistry.
Area of Science:
- Dental Science
- Biomechanics
- Occlusion Research
Background:
- Dentists use supine positions during procedures, while patients adopt various head postures during mastication.
- Understanding head posture's effect on occlusal contacts is vital for effective restorative dental rehabilitation.
Purpose of the Study:
- To evaluate the influence of different head postures on dynamic occlusal parameters.
Main Methods:
- 50 dental students (18-25 years) were studied.
- Evaluated head postures: supine, upright sitting, and alert feeding.
- Standardized head posture with a goniometer; analyzed dynamic occlusal contacts using T-scan.
Main Results:
- Occlusion time varied significantly across head postures (supine, upright, alert feeding).
- Disclusion times for right and left lateral movements also showed significant differences based on head posture.
- Statistical analysis (ANOVA) confirmed significant changes in occlusal contacts with varying head postures.
Conclusions:
- Head posture significantly influences initial occlusal contact, occlusion time, and disclusion time.
- Findings highlight the importance of considering head posture in dental assessments and treatments.
