Primary Outcome Measures

Name	Time	Method
Evaluation of risk factors, influencing the success of build-ups.<br><br>The observation period will start with the date of build-up restoration. Whenever the build-up restoration will be ‘recemented’, renewed, or the tooth will be extracted the intervention will be considered as failed. When the build-up restoration will still be in function at the last check-up visit and will found to be clinically acceptable, the intervention will be considered successful.<br><br>During the regular check-ups, the buiold-ups are monitored. No restriction in respect to the last check-up is given.<br>

Secondary Outcome Measures

Name	Time	Method
Evaluation of risk factors, influencing the survival of build-ups.<br><br>The observation period will start with the date of build-up restoration. Whenever the tooth will be extracted the intervention will be considered as failed. Whenever the tooth can be prevented from extraction (e.g. by ‘recementing’ or renewing of the build-up restoration) the observation period will not be considered as censored or failed. When the tooth will be still in function at the last check-up visit and will found to be clinically acceptable, the intervention will be considered ‘successful’.
