Intracoronal

Intracoronal refers to a location or position that is within the crown of a tooth. The crown is the part of the tooth that is visible above the gum line. Therefore, intracoronal treatments or restorations are those that are placed entirely within this visible portion of the tooth.

In dentistry, the term intracoronal is frequently used to describe the placement of dental restorations such as fillings, inlays, and onlays. A filling, for instance, is an intracoronal restoration because it is placed into a prepared cavity within the tooth's crown. Similarly, an inlay is a type of restoration that is fabricated outside the mouth and then cemented into a prepared cavity within the tooth. It is also considered intracoronal as it fits within the confines of the tooth's crown. An onlay is similar to an inlay but extends over one or more cusps of the tooth, though it still primarily occupies the intracoronal space.

The distinction between intracoronal and extracoronal restorations is important in dental treatment planning. Extracoronal restorations, such as crowns or veneers, cover the external surfaces of the tooth. Intracoronal restorations, by contrast, are confined to the internal structure of the tooth's crown. This classification helps dentists determine the appropriate materials, techniques, and the extent of tooth preparation required for a given dental procedure. The depth and location of decay or damage within the tooth are key factors in deciding whether an intracoronal approach is suitable.
