Patients older than 18 years who are treated at the Department of Prosthetic Dentistry, University of Freiburg, Germany are included in the study. The patients are in need of dental crowns or three-unit dental bridges for medical reasons. The dental crowns or dental bridges can be part of a larger prosthetic treatment in which the patients receive further dental crowns/bridges or a removable denture. A provisional phase of at least 6 months is necessary. The patient's general state of health must permit dental treatment. The pain-free jaw opening must be larger than 40 mm.
Patients younger than 18 or patients who cannot give informed consent for other reasons are excluded. Patients with known allergies to the materials used are also excluded. Patients who cannot/should not undergo dental treatment due to their current state of health, as well as patients who are not in need of crowns/bridges for medical reasons or who require definitive treatment in the near future, are also excluded from the study. Another exclusion criterion is a pain-free mouth opening of less than 40 mm and a refusal to participate in the study.

- Primary Outcome Measures
Name Time Method Gingival health measured as bleeding on probing (BOP).<br>This is mesured when the first temporary restoration is inserted, when the second temporary restoration is inserted after 3 months and after the second temporary restoration has been replaced by the permanent restoration after 6 months.
- Secondary Outcome Measures
Name Time Method Fit and surface texture of the provisional crown or bridge, plaque accumulation on the provisional, patient satisfaction/quality of life with the provisional, fracture and debonding rates, esthetics and wear through chewing process.<br>The clinical examination of the temporary restoration, the intraoral scan to check for wear and the quality of life questionnaire are also carried out when the first temporary restoration is inserted, when the second temporary restoration is inserted after 3 months and after the second temporary restoration has been replaced by the permanent restoration after 6 months.
