Bridges/Crowns:

Bridge and crown treatment is a long-term method of replacing missing teeth. A Crown is placed over an individual tooth where there is no longer sufficient tooth structure left to place a filling. A bridge spans space where one or more teeth have been lost in the dental arch. The teeth on either end of the span are crowned, and are referred to as abutments. The false teeth in a bridge that join the abutments are referred to as pontics.

For larger restorations, that require more strength, we are now able to remove the decay, and prepare the tooth for a partial coverage inlay/onlay, that only removes the damaged tooth structure not the whole tooth down to the gum line. In the past, we would then take an impression, make a temporary, and have the patient come back in two weeks for cementation of the inlay/onlay. Now we can take an optical three dimensional picture of the prepared tooth with our CEREC machine and design the crown on the computer and have your onlay milled out of block of porcelain in under 30 minutes and then cement your onlay the same day before you leave.

CEREC Crowns:
Technology has taken the crown process to the next level… It’s called the CEREC! The Cerec machine does this entire process in about an hour, saving you that second dental visit and hours of your time. First, the crown is made of 100% porcelain. It is cintered which means it is put under pressure and heat to make its qualities like that of enamel in hardness and wear. Second, There are no impressions to take and send to the lab. The Cerec crown is made with a CAD / CAM machine. CAD stands for Computer Assisted Design and CAM is for Computer Assisted Machine.With the Cerec an infrared photo is taken of the tooth and brought into the computer. In the computer the dentist now designs the crown. Next, a block of porcelain is placed in a milling machine. The dentist then sends the crown design to the milling machine. The Cerec milling machine then takes that block of porcelain and mills out the crown. The milling process takes about 10 to 15 minutes. Third, the porcelain crown is then removed from the mill. The dentist now cements the porcelain crown using a new generation of cements that bonds to the tooth and to the porcelain. This gives the new restoration additional strength. A good example is a thin piece of laminate is very weak and brittle on its own, but when bonded to wood it gains a great deal of strength. Cerec crowns are very natural looking, have a very precise fit, are durable and can be made in one dental visit in about one hour saving you hours of your time..

Dentures:
Dentures are removable replacements for missing teeth typically made out of an acrylic resin which may at times incorporate porcelain or metal for additional structural support. There are two main types of dentures, complete and partial. Both complete dentures and partial dentures are finely crafted and custom-fitted to the patient. If you properly maintain your dentures they will appear natural and provide a perfect smile. Additionally, dentures help strengthen muscles controlling your expressions that require the support of your teeth, rid you of pronunciation problems caused by missing teeth and aid with chewing.
