The term CAD/CAM dentistry is literally a shortening of Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM) aka "one-visit-crown," in dentistry. The CAD/CAM machine provides the dentist with dental crowns, which are milled from blocks of white composite resin or porcelain, matching the shade of the restored tooth. Once the treated tooth is shaped and prepared, an image is taken of this defected tooth. The image then provides the data for a computer and the software is used to create a porcelain or resin composite piece for the defect, essentially creating a virtual dental crown.
The CAD/CAM dentistry software then sends this virtual data to a milling chamber in the lab where the dental crown is carved out of a solid block of composite resin or porcelain. Our standard of quality, here at Kneib Dentistry, is the highly esthetic, high strength e.Max porcelain ceramic crown. The resultant dental crown can then be adjusted in the patient's mouth and cured/bonded in place. Following acid etching of both the underside of the crown and the topside of the tooth itself (which increases the surface area on both opposing surfaces), composite resin materials are then used to fuse the resultant crown to the tooth, completing the dental crown procedure.
What are silver-mercury fillings?
For over 100 years, dentists have been using silver-mercury amalgam fillings to restore decayed or broken teeth. The only other alternative was gold.
At Kneib Dentistry, there is a new and economical way to restore teeth using tooth-colored resin fillings. The resin is made up of glass particles in a plastic matrix. Dr. Kneib bonds the putty-like material to the tooth with a high-intensity light. This hardens the material and allows it to be shaped and polished for immediate use.
Once completed, your tooth has a natural appearance and is actually stronger than before due to the strength of the adhesive agent used to bond the resin to the tooth. Resin restorations not only look better, but they are stronger and longer lasting than the old silver-amalgam fillings. Resin restorations can range from $150 to $350 per tooth.
What is dental bonding?
Bonding by Dr. Kneib can yield dramatic results in a single office visit. Bonding essentially hides any natural flaws through the placement of a thin plastic coating on the front surface of the teeth.
After treating the tooth's surface, Dr. Kneib applies a putty-like bonding material that is then sculpted, shaped, and colored to suit your needs. A high-intensity light causes the plastic to harden, after which the new surface is smoothed and polished.
Bonding can lighten stains, close gaps, and even alter crooked or malformed teeth. At Kneib Dentistry, we can even utilize it to change the shape or color of a single tooth or, if necessary, to remake your entire smile.
What are tooth-colored restorations?
For over 100 years, dentistry has restored teeth primarily with a material made of mercury and silver. It has done its job well, although we have had to live with its weaknesses. Those weaknesses consist of cracked teeth due to the expansion of the material and restorations turning black as the silver in the material corrodes.
We have many ways to provide tooth-colored restorations at Kneib Dentistry. We can use adhesives to bond tooth parts that look and act like teeth. We can provide a bright, healthy, and strong smile with these exciting new techniques in adhesion dentistry.
What are cosmetic dental crowns?
Teeth are often restored with fillings of silver or composite plastics. These materials can often accomplish the aim of replacing the part of the tooth that has been lost in a strong and good-looking manner.
However, there comes a point when the damage to the tooth has removed too much structure to hold a filling. The restoration must be done by a technique that will attach to the remaining tooth, stand up under heavier use and meet more elaborate cosmetic requirements.
The crown is the dental restoration that can strengthen and restore the entire top of a tooth. The crown can also be part of the attachment of a fixed bridge for the replacement of teeth. The tooth is strengthened because it is covered from the outside with a casting of metal or ceramic that will wrap up and splint the tooth.
The chewing of the tooth can be improved because it can be reshaped to match more efficiently with the opposing teeth. A crown can improve cosmetics by the use of modern ceramic processes that produce translucency and color that is more natural than has ever been possible.
A high-quality porcelain crown that we fully recommend is Ivoclar Vivident's e.Max crown. The benefits of the product include high strength, high durability, and esthetic appeal all in one. For more information visit our crown service page or ask about it when you come to visit us.
