Summary
Complete dentures can last over 15 years with proper maintenance. Patients with only one denture require more frequent interventions for repairs and relines to ensure longevity.
Area of Science:
- Dentistry
- Prosthodontics
- Biomaterials
Background:
- Complete dentures are essential for restoring function and aesthetics in edentulous patients.
- Assessing denture survival rates and maintenance needs is crucial for optimizing patient care and prosthetic longevity.
Purpose of the Study:
- To evaluate the survival time of complete dentures and the frequency of maintenance procedures.
- To compare denture survival and intervention needs between patients with complete dentures in both arches versus those with a single denture.
Main Methods:
- A retrospective study of 353 complete dentures fabricated between 1984 and 2009.
- Dentures were categorized into two groups: complete dentures in both arches (group 1) and a single complete denture (group 2).
- Denture survival, relines, base fractures, and artificial tooth loss were analyzed.
Main Results:
- Median denture survival was 15.8 years (mandible) and 19.4 years (maxilla) in group 1.
- Relines were most frequent in the maxilla; 5-year event-free rates were 69.7% (maxilla) and 80.5% (mandible).
- Denture base fractures occurred in 5.8% (group 1) and 15.2% (group 2), with tooth loss being rare.
Conclusions:
- Long-term function of complete dentures necessitates significant maintenance.
- Patients with a single complete denture require more frequent interventions compared to those with dentures in both arches.
