Model and die requirements:

1. Trim dies to the exact location of the margin. The die should have an undercut directly below the margin. Remove excess material apical to the margin for several millimeters.
2. Block out all undercuts with a neutral color wax.
3. Do not die space dies.
4. Do not mark margins with anything.
5. Do not use any die sealer.
6. For single units all we need is the die unless the coping needs to be built up for support of the ceramics.
7. Bridgework (on natural teeth or on implants) must have removable dies, removable pontic areas and removable adjacent tooth areas .
8. Bridgework models must be removable from articulator base.
9. Bridgework must be accompanied with a putty bite registration that fits the working cast. This bite registration must impress the opposing occlusion as the scanner will convert this bite to an opposing model.
10. Anterior cases and bridgework should have waxup and or study cast.
11. If you have mounted a large case on an adjustable articulator that is not an Artex or an Ivoclar Stratus Articulator, please ship us your articulator with the case.

When you receive your cases back:

1. If you feel the need to adjust zirconia we recommend a diamond impregnated wheel or fine high speed diamonds with irrigation.  For any larger adjustment use a coarse diamond. Be careful not to generate heat as this can compromise the zerconia.
2. Lightly sandblast outer surface with aluminum oxide and steam clean prior to porcelain application.

Thank you for your cooperation.
