Clinical Evaluating of Anterior Crowns Made of Zirconia Following Crown Lengthening

To clinically evaluate the technical response and vital relationship between the periodontal tissues and anterior dental crowns made from zirconia designed using CAD\CAM technology. The study sample consisted of 36 upper and lower anterior crowns requiring crown lengthening prior to crowning anterior teeth with zirconia for prosthetic and esthetic purposes. We surgically lengthened the teeth to be crowned, then prepared the teeth to receive all-ceramic crowns. The results demonstrated aesthetic and vital results and fulfilling the mechanical requirements of the final crowns. We conclude that performing crown lengthening procedures before replacing the anterior teeth helps restore the vitality and functionality of the final crowns.
