Age

18 Years to No maximum

Inclusion criteria

Inclusion criteria: 1. patients who have a fractured or deeply destroyed tooth that can be integrated into the overall prosthetic concept by extrusion as a valuable abutment. 2. healthy periodontium and inflammation-free periapical tissue or with a good endodontic prognosis. 3. patients of full age, who are mentally and physically able to understand the significance and scope of the study and to comply with the study personnel. 4. written informed consent signed before participation in the study.

Exclusion criteria

Exclusion criteria: 1. teeth not worth preserving or compromised roots with no prospect of preservation. Longitudinally fractured tooth roots. 2. Women with known pregnancy and/or breastfeeding. 3. study participation may, at the discretion of the investigator, pose an unacceptable risk due to pre-existing or concomitant disease or due to the patient's general underlying condition. 4. anticipated lack of adherence. 5. alcohol or drug abuse. 6. patient is institutionalized due to regulatory or court order. 7. persons in a dependent, or employment relationship with the sponsor or the investigator. The investigators are not authorized to substantiate the anamnestically collected patient data with corresponding evidence. The patients assure the validity of their statements
