Cerec Crowns

 

Have you had a crown made at your dentists office where a tooth was numbered and shaped, an impression had to be taken (this is the part that probably hurt), a temporary crown was cemented and then wait 2-3 weeks. Come back to the office to have the crown fitted and cemented to the tooth. It probably was not fun with your temporary crown, you may have had sensitivity issues or it may have fallen off.

To offer our clients the best service and latest technology we offer same day Cerec crowns. Cerec uses infrared imaging, computer CAD CAM design, and a precise miling machine to make your life easier. Did we mention it only takes 2 hours from finish to start!

Why do I want a Cerec crown?

  • Less time in the dental chair – half the number of appointments; fewer local anesthetic episodes.
  • Normally parts of the tooth must be cut away before a crown is placed. In most Cerec crown cases less tooth structure is lost. Preperations can be made by cutting away less of your tooth, which is always better.
  •  Cerec crowns are all porcelain so there is less of a chance you will have a allergic reaction. Many lab crowns have a metal substrate that porcelain is bonded to.
  • Less chance for complications – most temporary restorations leak or have other discrepancies that can sometimes lead to increased sensitivity and this can even create the need for further treatment such as root canal therapy. When the crown is started and finished in one appointment, the tooth structure is better sealed off and protected at an earlier stage with the result that risk of complications and/or sensitivity can be lowered.
  • Cerec is environmentally friendly and saves you money.
    a) Fewer materials used – most materials in the process have a far lower negative impact on the environment.
    b) Fewer appointments mean fewer miles driven in your car for transportation.
    c) Fewer appointments mean fewer wasted disposable materials including paper products, syringes, plastic products, autoclave cycles, rubber gloves, masks and so on.

How does it work?

An infrared camera takes images of the tooth after shaping and a CAD CAM computer program immediately downloads the images creating three-dimensional virtual models that can be viewed and manipulated on the computer monitor. The operator in the dental office then uses the program to design the crown or onlay that will replace the missing tooth structure. This usually takes about three to five minutes. Next a porcelain block is selected, is inserted into a milling machine and the software program sends a signal to the milling machine to create the design in porcelain. This takes about 13 to 18 minutes. Once completed, the crown is polished, tried in the mouth, adjusted and bonded into place. The entire process takes about 2 hours and there is a period of about ½ hour for design and milling that can be used to accomplish other needed dental work.

How does it compare to conventional crowns?

The process of manufacturing a metal base lab crown involves significant amounts of expensive consumable materials beginning with impression materials in the dental office, continuing through model making devices and materials and on to alloys of metal that are increasingly costly followed by use of firing ovens, casting machines and the like. Most of these materials are not particularly biodegradable. With Cerec, there is a very limited amount of disposable material needed. This helps lower the waste stream, much of it carbon footprint related, as well as the cost.
