In esthetic areas, using a composite core usually does not create an esthetic problem. However, if a cast post and core has been used, there is a possibility of a gray shadow appearing from under the crown.
To counter this issue, special composites called opaquers can be used. These composites have an opaque white color and, by applying a metal-bonding protocol, can be bonded to the metal core and mask the color of the metal. This method helps resolve the gray-tint problem and improves the final esthetics of the restoration.
Clinical explanation
In treatments of anterior teeth that require a post, core, and ceramic crown, recreating the color is one of the key and challenging points.
There are several options for choosing the post and core, including prefabricated posts and fiber posts, and cores are also available in a variety of materials.
