Porcelain Crowns and Other All-Ceramic Crowns are used to make crowns closely resemble a tooth as they have optical properties such as translucency, lustre and subtle colour variations necessary to mimic tooth appearance. In our Sydney CBD and Hunters Hills locations our experienced dentists use the latest in porcelain and other ceramic crown technology and fillings.
There are different types of ceramics used for crowns. These include porcelain, which is highly aesthetic, and Zirconia, which is extremely strong. A ceramic now often used is a lithium-disilicate ceramic known as E-Max. An E-Max crown combines great aesthetics with high strength and is often used for making all-ceramic crowns.
All-ceramic crowns do not have metal copings (internal metal framework) and so cannot discolour at the gum line as is sometimes seen with older crowns.
As discussed earlier, Dental Lounge endeavours to make your visit as pain free as possible. Our dentists employ happy gas, numbing gel and the Wand injection system (tiny needle and computer controlled delivery) to remove any pain. We also give you frequent breaks if the crown preparation takes time.
For CEREC crowns at Dental Lounge, the single appointment lasts from 1 to 2 hours depending on the complexity. Most of this time is you watching television, as the crown has to bake in a high temperature oven to achieve maximum strength and colour. If the crown has to be made off-site your will need two appointments of approximately 1 hour each time.
Similar to fillings, your dentist will assess the tooth and the crown needed. In most cases a CEREC designed and made crown (using E-Max ceramic) is suitable and can be done in one visit. However, cosmetic cases involving front teeth may require off-site lab made crowns. Gold and partial metal crowns also need to be made offsite. Your dentist will discuss with you which option is best for your needs.
