Summary
This meta-analysis reviewed conventional fixed bridges since 1970. The study found an overall survival rate of 74.0% after 15 years for these dental restorations.
Area of Science:
- Dental materials science
- Prosthodontics
- Clinical dentistry
Background:
- Conventional fixed bridges are a common dental restoration.
- Long-term durability data for these bridges is crucial for clinical decision-making.
Purpose of the Study:
- To perform a meta-analysis of the dental literature since 1970.
- To present clinical data on the durability and survival rates of conventional fixed bridges.
Main Methods:
- A systematic search of dental literature published from 1970 onwards was conducted.
- 42 publications containing durability data for conventional fixed bridges were identified.
- Data from 4118 conventional bridges across 33 different samples were analyzed after excluding 26 studies.
Main Results:
- The meta-analysis included data from 4118 conventional fixed bridges.
- The overall calculated survival rate for conventional fixed bridges was 74.0% +/- 2.1% at the 15-year mark.
Conclusions:
- Conventional fixed bridges demonstrate a substantial survival rate over 15 years.
- Further research may focus on factors influencing long-term bridge success.
