Summary
Dental restorations like bridges and crowns have varying survival rates. Bridges had the highest survival rate at 64% after 15 years, followed by single crowns (56%) and fixed splints (45%).
Area of Science:
- Dental prosthodontics
- Biomaterials science
- Clinical dentistry
Context:
- Survival analysis of dental restorations is crucial for long-term patient care.
- Understanding factors influencing restoration longevity informs clinical decisions.
- Data from a private insurance company provides real-world insights into restoration performance.
Purpose:
- To investigate anatomical, constructional, and individual factors affecting the survival time of dental restorations.
- To determine the long-term success rates of single crowns, bridges, and fixed splints.
- To identify significant risk factors influencing restoration failure.
Summary:
- Survival analysis was applied to 4371 single crowns, 1669 bridges, and 175 fixed splints over 15 years.
- After 15 years, 64% of bridges, 56% of single crowns, and 45% of fixed splints remained functional.
- Significant risk factors included the number of abutments and units, location, date of insertion, jaw, and bridge type (extension/normal).
Impact:
- Provides evidence-based data for dentists and manufacturers on restoration longevity.
- Highlights the importance of specific clinical and design factors in achieving successful long-term outcomes.
- Informs insurance providers about the long-term performance of various dental prostheses.
