Preparation Instruction |
|
| |
Anterior full-coverage crowns require a chamfer or shoulder margin. A circular shoulder is prepared with rounded inner edges or a chamfer at an angle of 10-30°: the width of the shoulder/chamfer is approx. 1 mm. Facial reduction is 1.5-2.0 mm; 1.0-1.5 mm lingual contact clearance. Incisal reduction is 1.5-2.0 mm with rounded internal line angles, and an incisal edge at least 1mm wide to permit optimum milling of the incisal edge during CAD/CAM processing. |

Cementation Recommendations |
|
| |
For greatest strength, and where preparation allows for dry field (supra-gingiva margins), it is recommended to use adhesive bonding, such as Multilink Automix (Ivoclar Vivadent) or similar dual cure materials. For areas subgingival, or when a dry field cannot be achieved, Ivoclar Vivadent recommends a hybrid glass ionomer cement system with less than 0.5% expansion. |
