Same Day Crowns and CEREC


The CEREC procedure

The truth: Very few of us have perfect teeth, free of decay and fillings. In many cases, those fillings are made of metal material and can go bad, weaken the tooth, or experience additional decay under or around the filling. In fact, 1.2 billion of these metal fillings will need to be replaced in the next 10 years. CEREC is a method used by thousands of dentists worldwide since 1987 not only to replace these fillings, but also to restore any tooth that is decayed, weakened, broken, etc. to its natural strength and beauty. Better yet, it’s done with all-ceramic, tooth-colored materials in a single appointment!


Exam and preparation

First, Dr. Weimar examines the tooth and determines the appropriate treatment. It could be a simple filling or a full crown, depending on Dr. Weimar's clinical judgment and how much healthy tooth structure remains. Next, he administers an anesthetic and prepares your tooth for the restoration, removing decayed and weakened tooth tissue.


Optical impression

Then, Dr. Weimar takes an optical impression of the prepared tooth. Instead of filling a tray with impression “goop” that you must bite into and hold in your mouth until it hardens, Dr. Weimar coats the tooth with a non-toxic, tasteless powder. A camera is then used to take a digital picture of your tooth. The entire optical Impression process takes only a minute or two.


No temporaries

Next, the CEREC machine helps Dr. Weimar create the restoration for your tooth. The CEREC 3D software takes the digital picture and converts it into a 3-dimensional virtual model. Dr. Weimar then uses his dental expertise to design the restoration using the CEREC 3D computer program. When completed, the restoration design data is sent to a separate milling machine in the office. A ceramic block that matches your tooth shade is placed in the milling machine. About 10 – 20 minutes later, your all-ceramic, tooth-colored restoration is finished and ready to bond in place. Finally, Dr. Weimar tries the restoration in your mouth to ensure proper fit and bite. The restoration is then polished and bonded to the prepared tooth. Your tooth is restored with no “temporary” or return trip necessary. All of this is done in a single appointment!

What is CEREC? CEREC is an acronym…

Chairside: The technology is in the dental operatory and used while you are in the chair
Economical: The procedure is economical
Restorations: The procedure restores your tooth to its natural beauty, function, and strength
Esthetic: The restorations are metal-free and tooth-colored
Ceramic: High-strength ceramics are used that are close in composition to your natural tooth structure


CEREC is an advanced dental restorative system that allows Dr. Weimar to restore decayed teeth, place crowns, remove defective amalgam fillings, or place cosmetic veneers in just one appointment. This allows you to have the highest quality, most lifelike dental restorations with minimal time investment.


CEREC Acquisition Unit

The CEREC Acquisition Unit is mobile and houses a medical grade computer and the CEREC camera. Dr. Weimar uses the camera to take a digital picture of your prepared tooth. This picture is used instead of a traditional impression. This means no irritating impression tray. The computer and CEREC 3D software converts the digital picture to a three-dimensional virtual model of your prepped tooth. Dr. Weimar then designs your restoration right on screen using the software while you wait (and watch!). This software can assist your dentist with designing any single tooth restoration: crowns, inlays (fillings), onlays (partial crowns), and veneers. Once Dr. Weimar has designed your restoration (usually about five minutes), he clicks a button, and the design data is communicated via a wireless radio signal to the CEREC Milling Unit.


CEREC Milling Unit

Dr. Weimar or his dental assistant will select a ceramic block that matches the shade of the tooth being repaired. He then inserts the block into the Milling Unit. The data from the Acquisition Unit is used to direct two diamond-coated burs to carve the block into the indicated shape of the restoration. This process usually takes 8 to 18 minutes depending on the size and type of restoration. After the milling is finished, Dr. Weimar polishes the finished filling or crown and bonds it into place.


CEREC is a registered trademark of Sirona Dental Systems



Our goal is to provide dentistry that is as seamless and undetectable as possible. We replace existing crowns and fillings with restorations that look and feel like your natural teeth.


Even in cases of extreme tooth damage, we can use porcelain crowns to make the smile appear "as new." Porcelain crowns present a reliable technique for repairing the most severe of dental problems, even permanently replacing missing teeth to offer a complete smile and a functional bite. We are renowned for the quality of our work and the life-changing treatments we provide.


Q. How long does it take to fit a dental crown?

A. Fitting a crown requires two visits to our office (except in the cases of a CEREC crown, which is completed in only one appointment). Initially, we will remove decay, shape the tooth, and fit it with a temporary crown of a composite or tooth-colored material.

On the subsequent visit we will remove the temporary crown, and then fit and adjust the final crown. Finally, we will cement the crown into place, leaving you with a beautiful new tooth.


Key Benefits of a dental crown:

  • Replaces missing teeth
  • Offers support to misshapen teeth or badly broken teeth
  • Looks completely natural
  • Fixes “smile” and functional chewing problems

Capabilities of dental crowns

Crown and bridgework is a trusted solution for major dental problems caused by breakdown of the natural teeth, accidents, periodontal disease, and more. Material used in these repairs is either high-grade porcelain, or porcelain bonded to gold. A higher strength of the porcelain and gold materials is recommended to treat the most serious of dental problems. Crowns and/or bridges can provide a long-term solution for accidental damage, lost or broken teeth, or broken fillings.


Many people have unexplained pain from filled back teeth, which is typically due to hairline cracks in the chewing part of the tooth. Placing crowns on these teeth relieves the pain and allows a return of full dental function for these teeth. In front teeth, older fillings can both weaken the teeth and cause “appearance” problems due to staining or chipping. Porcelain crowns and bridges are suitable in cases where porcelain veneers are not. In teeth with root canal fillings, crowns can prevent breakage.
