Dental Milling Burs for CAD/CAM

Dental milling burs are used by dental professionals to create molds and dental implants that are an exact match for the intended patient.
CAD/CAM which stands for computer-aided design/computer-aided manufacturing has been used largely in many engineering and manufacturing fields. Just over 20 years ago the technology was used to design a method called CEREC which is a method that creates porcelain dental restorations in as little as an hour instead of days. This type of dentistry is used to improve the design and production of dental restorations including crowns, crown layers, inlays and onlays, veneers, dentures, fixed bridges, dental implant restorations, and orthodontic appliances.

CAD/CAM enhances earlier technologies used for these restorations by increasing the speed of design and creation; reducing the unit cost; improving the ease or purity of the design; creation and insertion steps; and making possible and affordable restorations and appliances that otherwise would have been unattainable or immensely expensive for patients who needed them.
Typically to have a crown placed, first a temporary crown is placed from one to several weeks while the restoration is produced in a dental laboratory or an in house dental lab.
After the crown has been made the patient returns to have the temporary removed and the lab-made crown cemented or bonded in place. With a CAD/CAM system, the dentist is able to create the finished restoration the same day, sometimes in as little as an hour. This saves the patient from having to come back for multiple visits.
Chair side dental CAD/CAM systems are designed to provide a complete digital workflow including a digital impression system, 3D dental design software, and a chair side mill that function as a single system. These systems that are designed to provide a seamless workflow, allow dentists to provide patients with crowns, inlays, onlays, and veneers in a single appointment.
CAD/CAM dental restorations are typically milled from solid blocks of ceramic or composite resin that best match the shade of the tooth being restored.

A digital impression draws an image of the prepared tooth and the surrounding teeth into a computer. Next is a process called reverse engineering where proprietary software creates a replacement part for the damaged tooth by creating a virtual restoration. Then a milling machine receives this virtual data and the replacement part is carved out of a solid block of ceramic or composite resin. To correct the regular appearance of the restoration, stains and glazes are fired to the surfaces of the milled ceramic crown or bridge. Finally the restoration is adjusted in the patient’s mouth and cemented or bonded in place.

There are several advantages to using CAD/CAM systems instead of previously used methods.
One benefit is the accuracy of shape prevents gapping between the crowns and surrounding teeth.
Another advantage is that the immediate 3D images take away the need to taking time-consuming and often uncomfortable impressions of teeth. Also computer sculpting creates a much healthier restoration
for the tooth in a matter of minutes. Finally CAD/CAM restorations are better fitting, more durable, and more natural looking than the previously made restorations.
