Statement of problem
Long-term practice-based clinical evaluations of various contemporary ceramic crown
restorations from multiple practitioners are limited.
Purpose
The aims of this study were to evaluate the clinical performance of ceramic single
crowns and to identify factors that influence their clinical performance.
Material and methods
Ceramic single crowns that had been placed at the Mayo Clinic and in function since
2005 were identified and included in the study. The restorations were examined clinically,
radiographically, and with photographs. Modified United States Public Health Services
criteria were used for the clinical evaluation. The ceramic systems evaluated were
bilayer and monolayer.
Results
Fifty-nine patients (41 women, 18 men) with 226 single teeth and implants restored
with single ceramic crowns were identified. The mean duration from insertion date
to study examination date was 6.1 years. Thirteen restorations (6%) were replaced
at a mean 3.3 years after insertion date (range, 0.1-6.1 years). Estimated replacement-free
survival rates (95% confidence interval [CI]; number of teeth/implants still at risk)
at 5 years after insertion date were 95.1% (95% CI, 92.2-98.1; 153) and at 10 years
were 92.8% (95% CI, 89.1-96.8; 8). The most common reason for replacement was fracture
to the core of posterior layered ceramic crowns. The most commonly used luting agent
was resin-modified ionomer cement. Most restorations exhibited clinically acceptable
marginal integrity, shade, no caries recurrence, and no periapical pathology.
Conclusions
The clinical performance of ceramic single crowns at 5 and 10 years supports their
application in all areas of the mouth. With the majority of fractures to the core
occurring early in the lifetime of layered ceramic posterior crowns, consideration
of other monolithic ceramic systems for posterior crowns is advised.
