[Dicor glass ceramic crowns]

Within a period of 36 months 103 Dicor glass ceramic crowns have been inserted. Total loss of function occurred in 8 of the restored teeth in the form of loss, partial or total fracture of the crown. In 15 cases a partial loss of function was observed due to esthetic damage, abrasions or cement washouts. Before treatment 73 teeth had been sensitive on probing, after restoration 4 of them required endodontic treatment. Many of the reasons for loss of function could be found. These results suggest that, although sensitive to technical errors, this technique provides highly qualified single tooth restaurations.
