04 Dec Cerec Dental Crowns in Edinburgh
Cerec or CEramic REConstruction is an amazing technology which we have had at the practice for over two years now. Many of our patients have now benefited from what one lady describes as “computer teeth”. It enables us to provide same day porcelain crowns, veneers, inlays and onlays in a minimally interventive way. (These words are different ways to describe filling in the gaps in your tooth after we have taken out the old filling or damaged tooth material). The system consists of a 3D digital camera and computer and a milling unit.
The tooth that needs fixed is numbed. We then remove old filling material and the minimal amount possible of weakened or damaged tooth material. The prepared tooth is sprayed with a blue powder,which lets the 3D camera pick up the image, and scanned. The images are saved into the computer and manipulated by the dentist using biogeneric software to design the shape of the restoration. “Biogeneric” means the computer has information about all tooth shapes but it also examines the nearby teeth to copy their characteristics. The designed restoration is then cut out of a block of porcelain by the milling unit.
We have several different types of porcelain we can use, the strongest at present being Emax. Emax takes a little longer as it has to be crystallised for 20-30 minutes to increase its strength. It is a lovely material which glazes beautifully and is our favourite for crowns. The properties of these materials are like tooth or stronger and as the the restoration will be bonded strongly to the tooth there is no need to make the shape of it mechanically retentive.
Once the restoration has been milled and crystallised/glazed, its fitting surface is treated for bonding. The surface of the tooth is also treated for bonding and a resin based bonding cement is then used to fix the restoration to the tooth.
It’s all very quick, there is no need for impressions, temporary crowns or waiting for work to come back from the lab. It’s the closest we can get to putting your tooth back the way it was when it first came into your mouth.
