Patient response to variations in complete denture technique. Part IV: Residual ridge resorption--cast evaluation
The Journal of Prosthetic Dentistry
|November 1, 1980
Summary
This study found minimal alveolar ridge changes in denture wearers after 10 years, regardless of fabrication technique. Factors like good prosthodontic care and patient characteristics likely contributed to the insignificant findings.
Area of Science:
- Dentistry
- Prosthodontics
- Oral Health
Background:
- Alveolar ridge reduction is a common consequence of complete denture use.
- Understanding factors influencing ridge topography changes is crucial for long-term denture success.
Purpose of the Study:
- To compare alveolar ridge topography changes over 10 years in patients with complete dentures fabricated by two different techniques.
- To evaluate the influence of denture fabrication methods on long-term ridge preservation.
Main Methods:
- A 10-year recall study involving 36 patients wearing complete dentures.
- Alveolar ridge topography was assessed using three distinct measurement methods.
- Comparison of ridge changes between two different denture fabrication techniques.
Main Results:
- Overall, minimal and statistically insignificant alveolar ridge changes were observed across all patients.
- Slight variations in ridge change were noted between the two groups based on subjective, width, and contourator tracing evaluations.
- No single denture technique was definitively proven superior in preventing ridge reduction.
Conclusions:
- The study did not establish a significant difference in alveolar ridge topography changes between the two denture fabrication techniques.
- Minimal ridge changes may be attributed to sound prosthodontic principles, regular patient recall, and favorable patient characteristics (young, experienced wearers).
- Further research with larger sample sizes may be needed to detect subtle differences, if any.
