One of the most important technological advances in modern dentistry involves the use of CAD/CAM (computer-aided design/computer-aided manufacturing) technology.
Dentsply Sirona's CEREC digital ceramic reconstruction system uses CAD/CAM technology. Thousands of clinicians worldwide use the CEREC system. To date, several million CEREC restorations have been successfully fabricated and placed in patients.
Dr. Thomas Tang uses the CEREC system to fabricate and place dental crowns in one visit to our Brookfield, WIpractice. In this blog post, we discuss the benefits of the CEREC system.
How Does the CEREC System Work?
The CEREC system can be used for a variety of purposes. These include the chairside fabrication of dental inlays, onlays, facial veneers, crowns, fixed bridges, and surgical guides.
To fabricate a restoration, the dentist uses a small wand with an intraoral camera to get 3-D images of the treatment area. The dentist can then make any necessary adjustments to the image, after which, the software creates an image of the final restoration.
The restoration is designed to precisely fit the tooth, fill in all missing tooth structure, cover the entire exposed portion of the tooth or teeth, and make proper proximal and occlusal contact with the adjacent teeth.
The computer then sends this finalized virtual restoration to a milling machine that is equipped with diamond-coated grinding burs or bits. The computer-driven machine fabricates the restoration from a solid block of ceramic.
The entire CEREC process takes just one appointment. Waiting for a laboratory to fabricate a final restoration, as is the case with the conventional method, can take days or weeks. As a result, the patient has to return to the dentist’s office for placement of the crown.
With CEREC, the patient can have the completed restoration fabricated and cemented into place in a single appointment.
Time and Cost Savings
The CEREC technique eliminates the laboratory costs that come with a conventionally made restoration. And since the treatment process is completed in one appointment, there is no need for a second appointment for the patient.
Other savings include the cost of materials and time involved in making impressions and fabricating temporary crowns.
The CEREC process scans and records the preparations and other oral structures directly in the mouth. Therefore, there is no need for a dental impression.
Impressions can cause gag reflex, and they may need to be taken several times. Even after several attempts, impressions can still be inaccurate, due to distortions in the material, ill-fitting trays, or operator error. An inaccurate impression can result in an ill-fitting final restoration.
Because the traditional method of fabricating dental restorations is a multi-step process, any error at any step can prevent the final restoration from fitting properly. CEREC eliminates this entire process, and it saves the dentist the cost of the impression material.
No Temporary Restorations
With CEREC, there is no need for the use of a temporary restoration. Temporary restorations, which are necessary with the conventional method, take time and materials to fabricate. In addition, if left in place too long, they typically wear, break, allow food impaction, cause gum inflammation, or become dislodged.
High-Quality Final Product
The final CEREC ceramic product is a non-toxic, tooth-colored material that looks and feels natural. CEREC restorations have been shown to be strong, anti-abrasive, plaque-resistant, and otherwise comparable to conventionally made restorations. Based on clinical studies, patients can reasonably expect them to last for 10 years or more.
