The effect of complete dentures on head posture.
This study investigated possible changes in head posture after insertion of complete dentures in patients who had been edentulous for at least 6 months. The craniovertical angle was measured with a plastic ruler and protractor assembly, which was aligned with dots made on the skin over the zygomatic arch. Readings were made before denture insertion, immediately after insertion, and 15 and 30 minutes later. Two-way ANOVA was used to analyze the results. When the predenture insertion values were included, statistically significant changes (p less than 0.01) in head posture were found. However, when the predenture values were excluded, no statistically significant differences were found. The results support the conclusions that head posture is significantly altered immediately after insertion of dentures in edentulous patients but within the next 30 minutes there is no statistically significant alteration in head posture.
