digital manufacturing process for the fabrication of fully anatomical composite bridges with a zirconia substructure and a feldspar/hybrid ceramic veneer structure
VITA Rapid Layer Technology
Digital composite bridges with the click of a mouse.
Features/Benefits
- reduction of time and costs using a digital manufacturing process for the substructure and veneer structure
- high reliability and minimized risk of chipping, thanks to monolithic veneer structure
- simple and reliable bonding of the substructure and veneer structure, thanks to adhesive bonding
Recommended indications*
- fully anatomical posterior composite bridges with up to four units
*) These are recommended indications; the entire range of single tooth restorations can normally be fabricated. For details, please refer to the respective working instructions of the products.

Can the surfaces of the VITA YZ restorations to be veneered be blasted with Korund (Al2O3) prior to veneering?
No, mechanical surface processing may cause damage to the structure in the sintered condition. This can lead to phase transformation of the zirconia and surface tensions, due to the distortion of the crystal lattice. Fissures or late cracks in the veneering porcelain are also possible after inserting the restoration. In order to avoid phase transformation, surfaces that are individualized with VITA VM 9 (blank or cut-back technique) or pressed over with VITA PM 9 (press-over technique) must not be sandblasted. The restoration should be cleaned under running water or with a steam jet prior to veneering. The surfaces should not be contaminated with foreign substances (e.g. skin fat, saliva) after they have been cleaned.
Can moist substructures be sintered?
No, all restorations must be dried completely before the sintering process. For this there are two methods available: either using an infrared lamp or the VITA VACUMAT 6000 MS pre-dry program. If moist substructures are sintered, there is a risk that cracks or fissures may form in the restoration.
Can restorations with different translucency levels be sintered with the same program?
No, because the materials have different sintering temperatures and heating rates.
Can restorations from VITA YZ SOLUTIONS Color or Multicolor be infiltrated with liquids?
As VITA YZ SOLUTIONS Color and Multicolor are already industrially precolored, liquid infiltration is not necessary.
Can restorations from VITA YZ XT be infiltrated with VITA YZ HT SHADE LIQUIDS, for example?
No, the VITA SHADE LIQUIDS can only be used on zirconia with the corresponding translucency level. If restorations are colored with a shade liquid of another translucency level, the desired tooth shade will not be achieved. Note: Shade liquids of different translucency levels should not be mixed.
Can VITA YZ SOLUTIONS materials be veneered?
Yes, all VITA YZ SOLUTIONS materials (VITA YZ T, HT, ST and XT) in white, color or multicolor can be fully or partially veneered. VITA VM 9 is designed for this.
Can VITA YZ restorations be conventionally cemented?
VITA YZ crowns and bridge restorations can be conventionally cemented.Note: High-strength oxide ceramics cannot be etched using hydrofluoric acid gel and must be sandblasted with Al2O3 (50 μm) at a maximum pressure of 2 bar on the inner surfaces prior to bonding to increase the retention.
Do the surfaces of monolithic restorations have to be polished before being placed in the patient's mouth?
Yes, since the surface roughness of unpolished zirconia causes increased loss of substance (abrasion) on the antagonist.
General recommendation for surface treatment of fully anatomical VITA YZ SOLUTIONS restorations:
Polish high-gloss areas which are in occlusion and then double glaze.
If the occlusal contacts have been ground off in the patient's mouth, polishing is also mandatory.
How should a restoration be positioned in a VITA YZ ST or a XT multicolor disk so that the restoration shows the desired shade gradient?
The restoration should be placed in the center. If a higher incisal area is requested, the restoration should be placed as far as possible into the incisal area of the disk. For a shade result with a higher intensity, the restoration can be moved into the deeper colored cervical area of the disk.
How can I determine which side the translucent blank for the incisal area for VITA YZ ST and VITA YZ XT multicolor disks is on?
The incisal blank is on the printed side of the disk.The disk must be mounted into the milling machine with this side facing upwards. Please note if the machine manufacturer provides any contradictory information.
What are the VITA YZ SHADE LIQUIDs for?
VITA YZ SHADE LIQUIDs are shade liquids that can be used to individually customize the VITA YZ HT, ST and XT by brush infiltration.
