PORCELAIN CROWN MATERIALS AND PRODUCTION PROCEDURE
MATERIALS USED FOR PORCELAIN CROWNS USED AT OUR DENTAL CENTER
Non-metal Emax/Zirconia/Vita porcelain crown (CAD/CAM) – Non-metal Emax/Zirconia/Vita porcelain crown on implant (10 years warranty at our center) are used up to 90% at Dr Hung & Associates Dental Center.
This is the restoration that has the best natural beauty as real teeth which is composed of a porcelain frame inside and outside covered by many layers of cosmetic porcelain with nano technology. It is also designed and manufactured by CAD/CAM technology at our Lab in-house to ensure the highest level of accuracy. Furthermore, this restoration will avoid the state of ‘dark collar’ after years of using.
Nano Emax (Ivoclar Vivadent) offer the fit, form and function which is expected from pressed ceramics. In addition, they offer improved flexural strength (400 MPa). With optimized esthetic properties creating all-ceramic restorations that offer true-to-nature results, Nano Emax is usually used for front teeth
Non-metal Lava – Ultimate porcelain crown (3M ESPE) is a type of Nano Ceramic resin from the US using the Nano Technology and suitable thermal procedure producing a special compound which is not only as natural as real teeth (therefore can be used for front teeth) but also very hard (so they can also be used for back teeth)
Non-metal Full Zirconia porcelain crown (Ivoclar Vivadent) is a type of porcelain crown made only from Zirconia material – a very hard type of non-metal. However, as zirconia does not have the natural teeth look, it is usually used for back teeth (especially for crowns on implants) to achieve the best chewing ability.
Crystal Ultra porcelain is suitable for crowns on implants, 3-unit bridges,… At 480 MPa, Crystal Ultra’s compressive strength is the strongest of all of the esthetic all ceramics and ceramic hybrids on the market. Crystal Ultra porcelain crown can be completed within 1 day. Crystal Ultra is registered with the Food And Drugs Administration (FDA).
Precious metal crowns (Gold, Platin, Paalladium,…) are crowns with frames made of highly valuable metals such as gold, platin, palladium,… covered with many layers porcelain for good biological impact, hardness and aesthetic factors. The only disadvantage of this solution is its high cost.
Additionally, we also use titanium porcelain crown & bridge – Titanium porcelain crown on implant (10 years warranty at our center) – a restoration which is as natural as real teeth. It is composed of a titanium frame inside and covered by many layers of cosmetic porcelain outside.
