Crowns & Bridges in the Digital Workflow
Crowns and Bridges are the most frequent restoration types within the fixed prosthetic segment. They can be made of various materials, e.g. dental alloys and all-ceramic materials.
In the field of all-ceramics, zirconium oxide is a leading material. It is an all ceramic (metal free) material and offers excellent properties for dental use: Superior toughness, strength, and fatigue resistance, in addition to wear properties and biocompatibility. Dentsply Sirona was a pioneer in this field with over 20 years experience. Zirconia became popular with introduction as pre-sintered material (Cercon) for efficient and economic production in CAD/ CAM processes. It covers a wide range of indications from single crowns up to 14-unit bridges.

* The accuracy of the results of the inEos X5 with inLab CAD SW 16.0 was verified according to DIN EN ISO 12836.2015. The demonstrated accuracy on standard “bridge” test specimens was at 2.1 ± 2.8 μm, and on standard “inlay” test specimens 1.3 ± 0.4 μm.
1. For validated sinter metal only
2. Optional with the inLab Profire Zirconia + Metal
3. For zirconium oxide; depends on the size of restorations and sinter support
The finishing of all-ceramic restorations is an essential component of aesthetics, quality and efficiency
Monolithic with just a glaze, or stain and glaze
The finishing of all-ceramic restorations is an essential component of aesthetics and quality.
Cercon Multilayers, Cercon ht ML and Cercon xt ML, can be finished with only a single glaze or by an individual characterisation with DS Universal Stain and Glaze.
The seamless layers delivers a natural aesthetics and especially in the anterior region Cercon ht ML can be used for covering discoloured dies, depending on the degree of discoloration and wall thickness of the restoration.
Cutback up to fully veneered
The cutback technique is particularly suitable for minimal individualisation, especially of the incisal area.
With the veneering ceramics Celtra Ceram or Cercon ceram Kiss, detailed individualisations can be carried out specifically and with little effort.
Cercon ht and Cercon xt are particularly suitable for this technique.
If a fully veneered restoration is desired or necessary for various reasons, it can also be fabricated with Celtra Ceram or Cercon ceram Kiss.
Cercon base in particular, but also Cercon ht and Cercon xt are suitable for this technique.
Example: 14-unit bridge, milled in Cercon ht ML, Shade A2, finished with Dentsply Sirona Glaze or Stain & Glaze
Example: Covering of discoloured dies with Cercon ht ML, Shade A2
