Objectives Nowadays, all-ceramic materials are routinely used within the treatment of patients in dentistry. The objective of this prospective clinical trial was the evaluation of chair-side generated monolithic lithium disilicate crowns after 10 years. Materials and methods Forty-one posterior full contour crowns made of lithium disilicate ceramics were inserted with a self-adhesive resin cement in 34 patients (20 university/14 private practice) using a chair-side CAD/CAM technique. One crown per patient was randomly selected for evaluation according to the modified US Public Health Service criteria. Results After a mean examination time of 10.1 years, 26 crowns were available for re-examination. Within the observation period, five failures occurred due to one crown fracture after 2.9 years, an abutment fracture after 6.0 years, one severe endodontic problem after 6.1 years, a root fracture after 7.0 years, and a replacement of one crown caused by a carious lesion after 10 years. Complications occurred as retention loss of one crown, two carious lesions, and a change in sensibility perception of two abutment teeth. All events were associated with molars. The Kaplan-Meier analysis revealed a survival rate of 83.5% and a complication-free rate of 71.0% after 10 years. Conclusion Due to the small amount of technical complications and failures, the clinical performance of monolithic lithium disilicate crowns was completely satisfying.
