Design outcomes

Primary

Measure	Time frame
Evaluation of risk factors, influencing the success of ceramic crowns. The observation period will start with the date of insertion of the ceramic crown. Whenever the ceramic crown will be ‘recemented’, renewed, or the tooth will be extracted the intervention will be considered as failed. When the ceramic crown will still be in function at the last check-up visit and will found to be clinically acceptable, the intervention will be considered successful. During the regular check-ups, the ceramic crown are monitored. No restriction in respect to the last check-up is given.	—
