Inclusion criteria
* The subject must be at least 18 (or age of consent), and less than 70 at the time of inclusion. * The subject is healthy and compliant with good oral hygiene * The subject is in need of a posterior fixed partial denture restoration 3 or 4 units distal of the canines in the maxilla or mandible. * The subject shall have a stable occlusal relationship with a fully restored, fixed opposing dentition. * Obtained informed consent from the subject prior to the study. * No apical disorder or inflammation of abutment teeth, adjacent and opposing teeth. * Good gingival / periodontal / periapical status of restoring, opposing and adjacent teeth. Healed situation of soft tissue augmentation is allowed. * The subject should be available for the 5-year term of the investigation.
Exclusion criteria
* The subject is not able to give her/his informed consent to participate. * Alcohol or drug abuse as noted in patient records or in patient history. * Reason to believe that the treatment might have a negative effect on the patient's total situation (psychiatric problems), as noted in patient records or in patient history. * An existing condition where acceptable retention of the restoration is impossible to attain * Mobility greater than grade 1 of the tooth to be restored. * Pathologic pocket formation of 4 mm or greater around the tooth to be restored * Severe bruxism or other destructive habits * Amount of attached soft tissue is insufficient (attached gingiva less than 2 mm or attachment loss greater than half of the root length). * Health conditions, which do not permit the restorative procedure
