Preparation
-
There are several varieties of permanent dentures which can be used to rectify tooth loss or decay. Some types of permanent dentures are crowns, bridges, and dental implants. While full dentures that are held in place using adhesives, suction and gravity are still used, they are largely being replaced by implant procedures. The preparation work for all types of permanent dentures is similar. The process typically begins with a visual examination of the teeth by the dentist. The extent of the tooth damage and the condition of the gums and ridges will help the dentist to determine the proper type of denture for the individual. An X-ray or CT scan is often performed on the jaw.
In some cases, a preparatory surgery must be performed to prepare the ridges to support some types of implants.
Crowns and Bridges
-
In cases where a single tooth or a group of adjacent teeth are damaged, a dentist may recommend the use of a crown or crowns. Crowns are typically used to protect teeth that have been damaged in some fashion. They can be made of metal, ceramic, resin or porcelain. Receiving a crown typically requires two trips to the dentist office. The first trip entails filing down the tooth that is to receive the crown. A mold is made and typically sent to an off-site facility for manufacturing. A temporary crown is put in place until the permanent crown is ready. On the second trip, the permanent crown is put into place with permanent cement.
When a tooth or teeth are missing, a bridge can be used to replace them. A bridge is affixed to the teeth surrounding the missing tooth or teeth. This also typically takes two visits. The first visit is used for examination and taking molds. Again, the prosthetic is typically manufactured off-site. The second visit is used for fitting and cementing the bridge.

Implants
-
The most common type of dental implant is a titanium alloy screw that has a crown affixed to it. Some preparatory surgery to prepare the ridges, but the implant procedure is relatively simple. A very small hole is drilled into the ridge of the jaw and then widened to accommodate the titanium screw. The implant is placed and affixed with a cover. The implants and covers are left in place for up to several months to allow the bone to attach to the implant (a process called osseointegration). Once the bone has attached itself, a temporary crown will be installed as a template for gum growth. When the dentist has determined that the gums are sufficiently prepared, the temporary crown or crowns will be replaced by permanent crowns.
