Summary
New dentures can improve stomatognathic system function and head posture in edentulous patients. Reduced free-way space and longer edentulousness correlate with dysfunction symptoms, but rehabilitation improves outcomes.
Area of Science:
- Dentistry
- Biomechanics
- Orthodontics
Background:
- Edentulism affects stomatognathic function and head/cervical spine posture.
- Dentures play a crucial role in restoring oral function and potentially influencing posture.
- Understanding these relationships is vital for comprehensive patient rehabilitation.
Purpose of the Study:
- To evaluate changes in stomatognathic signs/symptoms and head/cervical spine posture.
- To assess these changes in edentulous patients before and after new denture insertion.
- To identify correlations between edentulousness duration, free-way space, and postural changes.
Main Methods:
- Evaluated 10 edentulous patients.
- Recorded natural head posture using the fluid-level method on roentgen cephalograms.
- Assessed stomatognathic system signs and symptoms at baseline, immediately post-insertion, and six months after new dentures.
Main Results:
- Duration of edentulousness and free-way space positively correlated with dysfunction symptoms.
- Patients with greater need for oral rehabilitation showed increased head elevation post-denture adjustment.
- A reduction in the clinical dysfunction index inversely correlated with cervical spine posture changes.
Conclusions:
- New dentures can positively impact stomatognathic function and head posture.
- Free-way space reduction and duration of edentulism are key factors in dysfunction.
- Oral rehabilitation through new dentures can lead to improved postural alignment and reduced symptoms.
