Zirconium Oxide Post and Core System

Restoration of an Endodontically Treated Incisor

Irfan Ahmad, BDS

Due to their enhanced optical properties (eg, translucency, value, chroma), ceramic systems can provide natural aesthetics for restorations placed in the anterior segment. In endodontically treated teeth with stained dentin, however, the use of translucent ceramic materials may be contraindicated unless the underlying discoloration can be masked. This video describes the use of a zirconium oxide post and core system with an all0ceramic crown for the restorations of an endodontically treated anterior tooth. This system allows optical and mechanical requisites to be resolved simultaneously.

*Private practice, North harrow, United Kingdom

 

Learning Objectives:

This video describes a technique for the restoration of an endodontically treated anterior tooth utilizing a zirconium oxide post and core system with an all-ceramic crown. Upon completing this video, the viewer should have:

  • An understanding of the five individual requisites necessary for the adequate restoration of an endodontically treated tooth.
  • A comprehensive overview of the indications and preparation parameters for the utilization of a zirconium oxide post and core system.
