Brief Summary:
The aim of this study is to determine and compare the longevity of single-tooth cast restorations made of precious metal vs non-precious metal eg partial crowns crowns and to determine the influence of patient- tooth- treatment- and restoration-specific parameters on longevity
Patients who received single-tooth cast restorations made of precious metal or non-precious metal eg partial crowns crowns between 1997 and 2022 will be retrospectively analyzed Patient- tooth- treatment- and restoration-specific parameters will be obtained from digital and paper-based dental records
Survival and success of the restorations will be assessed using Kaplan-Meier statistics Mean annual failure rates mAFR and median survival time will be calculated Kaplan-Meier statistics Potential predictive factors will be tested using log-rank tests and multi-variate Cox-regression analysis
