Which restoration is indicated for an endodontically treated tooth with adequate supporting structure?

A complete crown is indicated for an endodontically treated tooth with adequate supporting structure because it provides comprehensive coverage and protection for the remaining tooth structure. After endodontic treatment, the tooth often loses vitality, and several factors can contribute to its increased susceptibility to fracture. A complete crown fully encapsulates the tooth, distributing functional forces more evenly and significantly enhancing its structural integrity.

This type of restoration is particularly beneficial when there is sufficient remaining tooth structure to support the crown. It helps maintain both the function and esthetics of the tooth, making it a preferred choice in cases where the tooth has a history of extensive restoration or decay.

In contrast, veneers and overlays are generally more conservative options and may not provide the necessary durability for an endodontically treated tooth, which often requires more extensive coverage. Intracoronal restorations may not offer adequate protection if the tooth has substantial loss of structure, as they are typically used in cases where only minor restorations are required. Therefore, the complete crown is the most suitable choice in this scenario due to its ability to restore strength and function effectively.
