Indications : Any position in the mouth where the preparation requirements can be met.
Use general veneer preparation techniques.
In general, you should perform a reduction in order to:
- Eliminate sharp line angles and edges
- Establish tapered axial walls - Provide adequate space for the coping and the dental ceramics
Conservative facial reduction (0.6 mm to 1.0 mm) is recommended.
Extend the palatal preparation by 1 mm (minimum) to 3 mm (maximum).
You can extend the preparation beyond the correct points to a maximum of 1 mm.
Note: The laminate core is only 0.25 mm thick.
Make a standard crow and bridge impression.
Send the impression to the dental laboratory.
3. Laboratory procedures
A model is made from the impression and scanned for producing a NobelProcera Laminate core.
After production, the core is veneered with dental ceramics.
Try-in the veneered NobelProcera Laminate ensuring that no major adjustments are necessary.
Sandblast internal surface
Clean in an ultrasonic solution of Iso-Propanol for 2-3 minutes and air-dry.
Apply ceramics primer containing phosphate monomer (MDP) on the internal surface of the laminate according to the manufacturer's recommendations.
Condition the preparations according to the manufacturer's recommendations, paying attention to moisture control.
Mix resin cement and apply to the internal surface of the laminate.
Seat the laminate with finger pressure, paying attention to complete seating.
Remove excess materior and light cure resin.
Perform a final check of occlusion, adjust if necessary, and polish.
For occlusal adjustments, use low speeds, new diamond drills, rubber polishing points, copious water irrigation and light pressure, followed by polishing with a diamond polishing paste.
Note: NobelProcara Laminates must be bonded.
