Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Patients who received single-tooth cast restorations made of precious metal or non-precious metal (e.g. 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.
