*depending on span width
VITA In-Ceram Classic SPINELL is recommended for the following indications:
- Anterior crown copings
- Posterior crown copings (but only in certain limited cases)
SIRONA inCoris NP is recommended for the following indications:
- Anterior crown copings
- Posterior crown copings
- Anterior bridge frameworks with up to 8 units*
- Posterior bridge frameworks with up to 8 units*
* irrespective of the number of pontics
Irrespective of the number of units, the minimum connector cross-section SIRONA InCoris NP is 5 mm2.
For reasons of structural stability we recommend elliptically shaped connectors (see illustration). This applies equally to metallic and ceramic bridge frameworks.
Preparation guidelines for ceramic materials
Ceramic crown and bridge frameworks require a chamfer or shoulder preparation. The shoulder width should be at least 1 mm. Tangential preparations are contra-indicated for ceramic materials.

Preparation guidelines for metallic materials
Chamfer, shoulder and tangential preparations can be created for metallic crown and bridge frameworks.
Bonding methods
The infiniDent crown and bridge frameworks can be conventionally cemented or else adhesively bonded.
