Full zirconia dental prosthetics
Full zirconia crowns and bridges
Full-anatomical zirconia in the posterior section of the teeth is a cheap and simple solution for dentists who want to use a full ceramic dental prosthetic without the risk of chipping. The insurance company pays 184 CZK more for full-ceramic than for other fixed prosthetics.
The advantages of full zirconia crowns:
Precise - there are made using CAD/CAM with the precision of 0.01mm.
Strong - their strength is 1 200 MPa.
Reliable - no chipping.
Convenient - the insurance company pays 182 CZK more than for PFM.
Esthetics - they are made of shaded zirconia.
Simple - no need to file to a shoulder.
Scanning zirconia dental prosthetics
is timewise and financially less demanding than PFM (Porcelain Fused to Metal). I use a diamond dental bur ball in green or blue coarseness. I make a vertical incision with the vestibular face which I finish at the chewing or incising face. The incision does not need to be a gingival cut through the whole framework. Then I use a dental lever to crack the crown open like a walnut.
