Summary
Complete dentures initially alter head posture in edentulous patients. However, this change is not statistically significant within 30 minutes after denture insertion, indicating adaptation.
Area of Science:
- Dentistry
- Biomechanics
- Human Physiology
Background:
- Edentulism, the condition of being toothless, affects oral function and potentially head posture.
- Complete dentures aim to restore function but may influence craniofacial biomechanics.
- Previous research on head posture changes post-denture insertion is limited.
Purpose of the Study:
- To investigate immediate and short-term changes in head posture following the insertion of complete dentures.
- To quantify alterations in the craniovertical angle in edentulous patients after denture placement.
Main Methods:
- A cohort of edentulous patients (edentulous for ≥6 months) participated.
- The craniovertical angle was measured using a ruler and protractor assembly.
- Measurements were taken pre-denture insertion, immediately post-insertion, and at 15 and 30 minutes post-insertion.
Main Results:
- Including pre-denture values, statistically significant changes (p < 0.01) in head posture were observed.
- Excluding pre-denture values, no statistically significant differences in head posture were found within the 30-minute observation period.
Conclusions:
- Head posture is significantly altered immediately after complete denture insertion in edentulous individuals.
- No statistically significant alterations in head posture occur between 15 and 30 minutes post-denture insertion, suggesting adaptation.
