CEREC®/One Visit Crowns

For over 15 years Dr. Crandall has used the revolutionizing Chairside Economical Restorations of Esthetic Ceramic (CEREC®) for 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 in a considerably shorter time here in our dental office. This means that many treatments can be completed in just a single visit. Therefore, we are able to have in-house quality control and avoid outsourcing to a lab.

CEREC® is comprised of several computer-assisted design (CAD) tools and a milling machine that creates custom ceramic restorative devices. CEREC® can make almost any ceramic restoration to order, meaning it can be placed immediately. This is of great benefit to nervous patients, and it can also reduce the cost of treatment.

How can CEREC® benefit me?

CEREC® can benefit almost anyone needing a ceramic restoration device. Exceptions include patients who have a prior history of breaking ceramic devices and those with a deep bite. Our practice has experienced 95% success rate in the past 15 years of providing CEREC ®  

Here are some other advantages associated with CEREC®:

  • 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, the closest material to natural tooth enamel.
  • No outsourcing of lab work to other countries.

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 enables Dr. Crandall to design the perfect ceramic restoration.

Three-dimensional CAD software: This software allows Dr. Crandall 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, which best resembles the existing tooth color is chosen and placed into the unit. Within minutes, the milling device produces the restoration the dentist designed. No horrible-tasting impressions or time-consuming transfers to and from the laboratory are required.

What does a CEREC® restoration procedure involve?

The first step in the procedure is to prepare the tooth. Any decay is removed; next, an image is made using a covering of titanium dust. This dust allows the camera to take a highly detailed picture of the tooth. 

The image is transposed onto the computer screen. It is here the final design is done. When the design is complete, it is transmitted to the milling unit. In order to ensure a natural look, Dr. Crandall chooses a block of ceramic that best matches the color of the teeth. The restoration is made of compressed, rather than laboratory-layered porcelain. This enhances strength and durability.

The restoration is then polished and affixed to the tooth with dental cement. The procedure is now complete, and all without the need for a second visit! The quality of the results is the same as the laboratory-generated restoration, but a great deal of time and money has been saved.
