NobelProcera™ Bridge Zirconia
Indications:
- Indicated for all positions in the mouth
- Bridges are available from 2 to 14 units in length. 20mm is the maximum height allowed.
- The connector dimension of a multi-unit framework depends on the distance between the supporting teeth
- Tooth- and implant-supported restorations
- Available in four different shades: white, light, medium and intense
Contraindications:
- Cases where the anterior/posterior cantilevers have a length of more than one unit
- Bruxism
Preparation
- Eliminate sharp edges, undercuts, and grooves.
- Establish tapered axial walls.
- Provide adequate space for the coping and dental ceramic porcelain.
- Provide suffi cient reduction (1.2 mm to 1.5 mm).
- Only select cases where you have the ability to result in a 3 mm connector height.
- Avoid sharp angles on the occlusal surface.
- Provide suffi cient occlusal/incisal reduction (1.5 mm to 2 mm) .
- Avoid preparations that are excessively tapered or too close to parallel. The ideal total occlusal convergence is 6–10°.
Impression
Make an ordinary crown and bridge impression using your preferred impression material and method and then send the impression to the laboratory.
Laboratory Procedures
- The dies and model are scanned using the NobelProcera Scanner. The data is transferred to a NobelProcera production facility.
- The bridge is milled from a presintered piece of zirconia, sintered to full density and returned to the laboratory.
- The restoration is completed using a zirconia veneering dental ceramics material and sent to the clinician.
Cementation
To save chair time, the NobelProcera Bridge Zirconia can be cemented using conventional crown and bridge cement or it can be bonded.
NobelProcera™ Bridge Alumina
Indications:
- Indicated for use in the esthetic region, premolar to premolar

- No cantilevers and a maximum of one pontic between supporting teeth/abutments
