A prefabricated endodontic rod designed for insertion into the root canal of a patient to support and retain a crown prosthesis. It is typically a solid, cylindrical, metal (e.g., stainless steel, gold alloy) piece with a proximal end appropriate to support the crown on top; it is, however, available in a variety of shapes, dimensions, and materials (e.g., ceramics, fibre-reinforced polymers). In addition, it is available in a variety of types (e.g., non-threaded, pre-threaded, or self-tapping; straight or tapered). This is a single-use device.
