Fixed Bridges

A dental bridge is a fixed (non-removable) appliance and is an excellent way to replace missing teeth.

There are several types of bridges.  You and your dentist will discuss the best options for your particular case.  The “traditional bridge” is the most popular type and is usually made of porcelain fused to metal.  This type of bridge consists to two crowns that go over two anchoring teeth (abutment teeth) and are attached to pontics (artificial teeth), filling the gap created by one or more missing teeth.

Dental bridges are highly durable and will last many years, however they may need replacement or need to be re-cemented due to normal wear.

Reasons for a fixed bridge:

  • Fill space of missing teeth
  • Maintain facial shape
  • Prevent remaining teeth from drifting out of position
  • Restore chewing and speaking ability
  • Restore your smile
  • Upgrade from a removable partial denture to a cemented, non-removable dental appliance

What does getting a fixed bridge involve?

Chairside Economical Restorations of Esthetic Ceramic (CEREC®) has revolutionized dental procedures. Traditionally, if crowns, onlays, inlays or dental veneers were required to restore damaged teeth, multiple procedures and a great deal of waiting time in-between would be inevitable. CEREC® creates these ceramic restorations within minutes in the dental office. This means that many treatments can be completed in just a single visit.

CEREC® is comprised of several computer-assisted design (CAD) tools and a milling machine that creates custom ceramic restorations. CEREC® can benefit almost anyone needing a ceramic restoration. This is of great benefit to nervous patients, and it can also reduce the cost of treatment. In addition, a patient does not have to wear a temporary crown while waiting for the definitive crown.

How can CEREC® benefit me?

CEREC® can benefit almost anyone needing a ceramic restoration.  Exceptions include patients who have a prior history of breaking ceramic restorations and those with a deep bite. CEREC® devices are proven to last for over 5 years, but recent research indicates that most CEREC®-created restorations last for more than 10 years.

Additional advantages associated with CEREC® include:

  • No temporary restorations
  • High-quality ceramic products
  • Minimal invasiveness
  • Less injections and discomfort
  • Fewer dental visits
  • Cost effectiveness
  • More natural tooth is saved
  • Long lasting restorations
  • Biocompatible solutions

What is the CEREC® system comprised of?

The CEREC® System is sometimes called a CAD-CAM system. CAD-CAM means Computer Assisted Design and Computer Assisted Milling. The CEREC® system has three major components:

Acquisition device: This device is home to a high-quality camera and a medical grade computer. The function of this unit is to photograph the prepared tooth. Three-dimensional images are created of the tooth on the screen, which the dentist uses to design the perfect ceramic restoration.

Three-dimensional CAD software: This software allows the dentist to examine the tooth from every angle. It is the closest possible thing to holding the tooth in the hands and rotating it.

Milling device: This unit actually manufactures the custom restoration from the specifications entered into the computer. A ceramic block that best resembles the existing tooth color is chosen and placed into the unit.  Within minutes, the milling device produces the restoration the dentist designed.

What does a CEREC® restoration procedure involve?

The first step in the procedure is preparing the tooth for the restoration.  Depending on your particular case, the dentist will take photos of your affected teeth using one of CEREC’s® two imaging solutions.  If using CEREC® Omnicam, the dentist will take several images of the tooth, sending a three-dimensional, colored model to the CEREC® machine.  If using CEREC® Bluecam, the dentist will coat the teeth with a contrasting agent before taking images of your teeth.

These images are transposed onto the computer screen, where the dentist will view the tooth from every angle and design the final restoration.  When the design is complete, it will be transmitted to the milling unit.  
The dentist will insert a block of ceramic, matching your tooth color, into the milling machine which will then create the full crown, onlay, inlay, or veneer.  Before affixing the restoration to the tooth, the dentist will perform a dry fit to ensure comfort.  Once a perfect fit is established, the restoration will be polished and affixed to the tooth with dental cement.
