Summary
Glass-ceramic restorations like IPS Empress 2 and IPS e.max demonstrate excellent long-term survival rates, exceeding 98% over 15 years in a general dental practice setting.
Area of Science:
- Dental materials science
- Restorative dentistry
- Clinical research
Background:
- IPS Empress 2 and IPS e.max are widely used glass-ceramic materials for dental restorations.
- Evaluating the long-term clinical performance of these materials in non-university settings is crucial for general dental practice.
Purpose of the Study:
- To assess the long-term survival rates of IPS Empress 2 and IPS e.max restorations.
- To identify factors influencing the survival of these glass-ceramic restorations in a real-world clinical environment.
Main Methods:
- A retrospective study analyzed 1,132 IPS Empress 2 and IPS e.max restorations in 251 patients.
- Survival rates were evaluated using Kaplan-Meier and regression analyses, considering patient demographics, tooth characteristics, restoration type, and cementation method.
Main Results:
- The overall survival rate for all restorations was 98.7% after a mean follow-up of 15.4 years.
- Factors associated with significantly reduced survival included nonvital teeth, patient age over 60, crown preparations, and self-adhesive resin cementation.
Conclusions:
- IPS Empress 2 and IPS e.max glass-ceramic restorations exhibit favorable long-term survival rates, up to 15 years.
- Clinical decision-making should consider patient-specific factors and restoration type to optimize outcomes.
