dental crowns


Crowns are ceramic dental restorations that are placed on the top of teeth.

Crowns are used to restore a tooth’s function and appearance following a restorative procedure such as a root canal. When decay in a tooth has become so advanced that large portions of the tooth must be removed, crowns are often used to restore the tooth. Crowns are also used to attach bridges, cover implants, prevent a cracked tooth from becoming worse, or an existing filling in jeopardy of becoming loose or dislocated. Crowns also serve an aesthetic use and are applied when a discolored or stained tooth needs to be restored to its natural appearance.

In our office, using Cerec 3D, a restorative crown is done in a single appointment, start to finish. Additionally, the metal-free ceramic material used with Cerec 3D closely match the composition of your natural tooth structure. Dr. Stender will administer an anesthetic and prepare your tooth for the restoration, removing decayed and weakened tooth tissue. Dr. Stender will then coat your tooth with a non-toxic tasteless powder and take a digital picture of your tooth. This is called an Optical impression and only takes a minute or two.

There is no “goop” impression tray to deal with. The Cerec 3D software takes the digital picture and converts it into a 3-dimensional virtual model on the computer screen. Dr. Stender then uses his dental expertise to design your restoration using the Cerec 3D computer program. About 10 – 20 minutes later, your all ceramic, tooth-colored restoration is finished and ready to bond in place. Once the restoration is checked for proper fit and bite, Dr. Stender will polish and bond the crown to your prepared tooth. Your tooth is restored with no “temporary” or return trip to the office. We believe that with Cerec 3D, we provide our patients with the highest quality of restorative care.


Bridges are natural-looking dental appliances that can replace a section of missing teeth. Because they are custom-made, bridges are barely noticeable and can restore the natural contour of teeth as well as the proper bite relationship between upper and lower teeth.
Bridges are sometimes referred to as fixed partial dentures, because they are semi-permanent and are bonded to existing teeth or implants. Some bridges are removable and can be cleaned by the wearer; others need to be removed by a dentist.

Porcelain, gold alloys or combinations of materials are usually used to make bridge appliances.

Appliances called implant bridges are attached to an area below the gum tissue, or the bone.
