A long-term prognosis for the free-end saddle-bridge
Journal of Oral Rehabilitation
|May 1, 1985
Summary
Saddle-bridges demonstrate a high success rate, with 98% functioning after five years. Long-term survival decreases over time, but they remain a viable dental restoration option, even with limited remaining teeth.
Area of Science:
- Dental prosthetics
- Restorative dentistry
- Prosthodontics
Background:
- Saddle-bridges with free-end saddles are a type of dental restoration.
- Long-term prognosis of these restorations requires evaluation.
Purpose of the Study:
- To assess the long-term prognosis of saddle-bridges with free-end saddles.
- To identify factors influencing the success and failure of these dental appliances.
Main Methods:
- A series of eighty-seven saddle-bridges were investigated.
- Data collected on functioning status at various time points (5, 10, 15, 20 years).
- Analysis of failure causes and influencing factors.
Main Results:
- 98% of saddle-bridges functioned at 5 years, decreasing to 49% at 20 years.
- Soldering fractures were common early failures; caries and loosening later.
- No significant influence found for sex, age, time of application, saddle length, or jaw location.
- Opposing removable dentures negatively impacted prognosis (P < 0.05).
Conclusions:
- Saddle-bridges have a very favorable short-term prognosis.
- Long-term prognosis is good, making them a viable alternative even with few remaining teeth.
- Careful consideration of opposing dentition is recommended for optimal outcomes.
