Indications
Our Dental Pfm can be used for crowns and bridges (up to fourteen units). PFMs Crowns can be manufactured to non-precious, semi-precious, and yellow high noble copings and can be used in conjunction with cast partials and implants.
Preparation
The ideal preparation for PFMs is a chamfer margin preparation. If a porcelain labial margin is prescribed, then a shoulder margin preparation is required.
Feather-edge margin preparations are indicated for full-cast restorations.
Cementation
- Panavia 21 – tin plated
- Glass ionomer cement (GC Fuji, GC America)
- Zinc Phosphate Polycarboxylate
- Resin Ionomer cement (RelyX, 3M ESPE)
Tech Notes
If an adjustment is required on the ceramic, use a fine diamond with water and air to keep the crown cool.
To contour the ceramic, polish with a pink rubber wheel and diamond polishing paste (Brasseler, Shofu, Vident).
