If the tooth has been rotted for a large portion of the tooth, the remaining tooth tissue usually cannot provide sufficient retention and resistance for the filling, so the filling restoration treatment cannot be carried out, and the dental core crown restoration treatment can be chosen.
When restorative dentistry is performed, the remaining tooth is required to provide the restoration with retention to avoid dislocation and resistance to avoid rupture of the remaining tooth and the restoration. Since the commonly used filling materials are composite resin and glass ionomer, which are of low strength, a tooth with a large portion of its body missing cannot provide sufficient retention and resistance, and therefore cannot be filled and restored.
Pile core crown is a full crown restoration that utilizes a pile inserted into the root canal to obtain retention, and is suitable for clinical crowns that are moderately defective or more, and the remaining teeth do not have sufficient retention conditions, making it difficult to provide crown restorations with retention force through direct filling.
It is recommended to go to a regular medical institution for consultation and professional treatment with the help of a doctor.
