Core Buildup, Including Any Pins - Dental Procedure Code Description

A "core buildup" is a form of dental restoration used to repair an excessively decayed, traumatized or otherwise damaged tooth. The term "core," is used to define the main body of the tooth's structure that excludes the root.  Effectively, it is what remains of the tooth's “crown,” - the portion of the tooth that can be seen above the gumline in a healthy mouth. 
With this dental procedure code, a "white" or "tooth-colored" filling made of composite resin is used to repair the damaged areas of the tooth, typically in preparation for the eventual placement of a prosthetic crown. Such resins are referred to as "tooth-colored" because of their unique ability to mirror the color, texture and luminescence of your own teeth. Resin also bonds more securely with the healthy portions of a tooth than traditional amalgam.
The process for this procedure is identical to that of a common “filling,” except typically a large surface area of the tooth needs to be repaired. This area can include the sides of the tooth as well as the biting surface. Additionally, metal pins are used to further secure the bonding material to the healthy portions of the tooth to enhance its stability and strength.
To prepare for a core buildup with pins, a dentist will first remove any decayed or weakened areas of the tooth. Then, your tooth would be prepared for bonding by etching it with a mild acid solution. After this, self-setting screw pins are screwed into the tooth to act as a framework for the composite filling which is then layered into its new form. Finally, a special light is used to harden these layers and the tooth is shaped and polished to provide the ideal look and biting surface in preparation for later prosthetic crown placement.
