Zirconia dental crowns are considered most durable and best cosmetic dental crown, and you can now get them in one day in Algodones!
Due to the expense of the system, most clinics will take an impression of your tooth and then mail the impression to a lab who has this system, which can take 5-14 days to finish.
Sani Dental Group has purchased a state of the art CAD/CAM (Computer Aided Drafting/Computer Aided Milling) system by KaVo Dental that can produce the best quality crown in one day. KaVo Dental is a US company that is recognized globally as one of the premium manufacturers of the latest dental technologies. You will get the exact same materials and quality of crowns as you would at home; for a fraction of the price and all in one day!
What are zirconia crowns?
Zirconia crowns are a full ceramic crown that utilize a zirconia ceramic core bonded to a porcelain exterior. The zirconia core is extremely durable, and this type of crown has the best quality natural appearance due to aesthetic porcelain layering that mimics the translucency of natural teeth.
As such, these crowns can be made without the metal understructure typical of other crowns. Traditionally, porcelain crowns are made by bonding the porcelain to a metal support in a process called Porcelain Fused to Metal (PFM). The porcelain in PFM crowns is traditionally bonded to metal alloys, gold, palladium, or titanium. The drawback is that unlike a natural tooth which exhibits a certain degree of translucency, the metal framework under the porcelain blocks out light. To the keen observer, the difference in shine and translucency between a natural tooth and a PFM can be quite obvious. For example, in natural light, a shadow can be seen in the interior of the tooth from the metal core. While full porcelain crowns (metal free porcelain jacket crowns, PJC) have been done (and are still being done), they are quite brittle and frequently break prematurely.
Advantages of Zirconia crowns
- No ugly gingival recession due to gingiva/metal reaction (dark line at the base of the gums)
- No exposed metal margin
- Excellent quality cosmetic appearance
- Ability to withstand high functional stress
- No thermal conductivity discomfort (no hot/cold sensitivity)
Zirconium dioxide has been used in the field of hip-joint prosthetics for roughly 30 years. It exhibits very high strength, high corrosion resistance and low thermal conductivity (no hot/cold sensitivity). The structure and the veneering material are both biocompatible and do not have any allergic potential. Zirconia is extremely durable and allows for the most durable porcelain crown available.
