As a zirconia dental lab, Dandy's zirconia crowns and bridges are renowned for their exceptional strength due to the unique properties of zirconia, a ceramic material known for its high resistance to fracture and wear, making it an ideal choice for dentists.
Dandy's Zirconia Offerings
Dandy offers three types of zirconia crowns with various strengths, durability, and aesthetics.
Aesthetic Zirconia
- Full-contour anterior or posterior crowns
- Offering greater translucency than monolithic yet less than PFZ.
Monolithic Zirconia
- Posterior crowns for bruxers and bridges up to an entire arch.
- Most opaque selection.
Porcelain Fused to Zirconia (PFZ)
- Single- to full-arch restorations
- Ideal cases include:
- Deep shoulder preparation
- Dark stumps with high translucency aesthetics.
