Our team of skilled technicians fabricate unmatched metal-based and all-ceramic restorations in our Maine-based dental laboratory. We offer highly esthetic crowns and bridges to fulfill anterior cases of varying difficulty. We are dedicated to crafting high-quality restorations out of the best materials available to ensure longevity and esthetics. We also offer veneers and PMMA provisionals.
Porcelain-fused-to-zirconia restorations offer the strength of PFM crowns, but eliminate the esthetic challenges that typically accompany metal-based products, such as discoloration or the dark line that can appear along the gingiva. They require conventional cementation and are hypoallergenic and biocompatible. Our team utilizes advanced CAD/CAM technology to ensure consistently accurate fit. Due to zirconia’s natural translucency, these crowns are warmer and provide superior lifelike coloration when compared to their PFM counterparts.
A CAD/CAM substitute for traditional PFM, our porcelain-fused-to-zirconia can be used for anterior and posterior crowns, crowns over implants, and bridges of up to fourteen units.
- Attachment cases
- Cases with less than 1 mm clearance
- Patients who have broken a PFM crown
- Cases that require bonding
The ideal preparation for PFZs is a chamfer margin preparation. If a porcelain labial margin is prescribed, then a shoulder margin preparation is required.
- Resin Ionomer cement (RelyX or RelyX Unicem, 3M ESPE)
- Maxcem Elite (Kerr)
- Panavia F 2.0 (Kuraray) - ideal for short, tapered preparations
- Glass ionomer cement (GC Fuji, GC America)
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).
