All-ceramic fixed restorations: a preliminary clinical evaluation

This article is a preliminary evaluation of a limited size clinical trial of all-ceramic fixed restorations. The maxillary anterior region in each of eight patients was restored with single-unit and three-unit fixed restorations, using a particular all-ceramic system. Patient selection, laboratory procedures, clinical techniques, patient follow-up, and the interim clinical results of the restorations, are presented and evaluated. The learning objective of this article is to review and update the knowledge of all-ceramic restorative materials and clinical procedures. Two of the eight cases in the study are presented to illustrate the clinical results.
