What the study is about
This investigation will be a randomized, prospective, longitudinal clinical trial to study the clinical performance of a new monolithic, zirconia material with shade, translucency and material graduation for chairside CAD/CAM crowns. The restorations will be luted either with a self-adhesive luting material or a conventional cement. The crowns will be evaluated for a period of two years.
Being studied: Crowns self-adhesively luted; Crowns conventionally cemented
Conditions: Dental Disorders Hard Tissues of Teeth; Dental Diseases

Inclusion Criteria
- at least 18 years of age

- tooth should have at least one opposing tooth in occlusion and one adjacent tooth with an intact proximal contact
- No more than ten teeth that are endodontically treated may be included in the study, equally divided between the two groups of crowns. All remaining teeth in the study will test vital and be asymptomatic at the beginning of treatment.
- No more than two restorations will be placed per patient
Exclusion Criteria
- Sensitive teeth
