Fig. 02 Preoperative occlusal view of tooth No. 13 and its failing MOD composite restoration.

Fig. 03 A full-coverage CAD/CAM restoration was proposed as the ideal treatment to maintain the tooth’s integrity.

Fig. 04 View of the preparation following removal of the defective restoration and decay.

Fig. 05 Adhese Universal bonding agent was applied to the preparations and cured.

Fig. 06 Tetric EvoFlow nanotechnology composite was placed to build up the preparation.

Fig. 07 The flowable composite was cured for 10 seconds.

Fig. 15 View of the glaze to be used when characterizing the IPS e.max CAD lithium disilicate crown.

Fig. 16 Stains were used to impart a lifelike appearance to the posterior restoration.

Fig. 17 IPS Empress Universal stains were used to characterize the restoration.

Fig. 18 A Programmat CS furnace was used on the fast cycle to fire the esthetically enhanced IPS e.max CAD restoration.

Fig. 19The intaglio surface of the restoration was etched with a 5 percent hydrofluoric acid for 20 seconds.

Fig. 20 Monobond Plus silanting agent was then scrubbed onto the intaglio surface and allowed to react for 30 seconds.

Fig. 21 The built-up preparation was selectively etched using 37 percent phosphoric acid.

Fig. 22 View of the etchant on the preparation.

Fig. 23 Adhese Universal bonding agent was scrubbed onto the preparation for 30 seconds.

Fig. 24 The bonding agent was light cured for 10 seconds.

Fig. 25 Variolink Esthetic light- and dual-curing cement in shade DC was placed into the restoration.

Fig. 26 After the restoration was seated, it was tack cured from the buccal and lingual aspects for three seconds each.
