商品簡介
Endodontically treated teeth (ETT) require restoration to restore form, function, and strength after loss of tooth structure. They are more susceptible to fracture due to reduced dentin, loss of structural integrity, and altered moisture content. The choice of restoration depends on remaining tooth structure, functional load, and esthetic demand.When minimal tooth structure is lost, direct composite restorations may be sufficient. If substantial structure is missing, a post and core is indicated to retain the final crown, though posts do not strengthen the tooth; they only provide retention. Prefabricated fiber posts are preferred due to their elastic modulus similar to dentin, offering better stress distribution. Cast metal posts are used when canals are flared or oval. A full-coverage crown is recommended in posterior teeth to resist occlusal forces and prevent cusp fracture. In anterior teeth, composite or ceramic crowns may be used based on esthetic needs.Overall, the aim is to preserve remaining tooth structure, ensure coronal seal, restore function, and prevent fracture.
