Guidelines for Endocrown Placement
The guidelines for Endocrown placement are as follows:
- The endocrown is indicated for the endodontic restoration of severely damaged molars 1
- The preparation technique requires a cervical margin in the form of a butt joint and a preparation of the pulp chamber that does not extend into the root canals 1
- The remaining tooth substance should be preserved to increase longevity 1
- A composite resin base can be used to fill undercuts and ensure a correct design of the preparations, contributing to significant tissue preservation 2
- The decision to omit a post is dictated by the amount of remaining coronal substance 2
- A rigorous adhesion protocol must be respected 3
- Lithium disilicate glass-ceramic and nanofilled composite resin are suitable materials for fabricating endocrowns 3
- Specific guidelines with minimal alterations should be followed for an endocrown restoration to be successful 4
- The use of computer-aided design/computer-aided manufacturing (CAD/CAM) manufactured restorations is a viable option 4
- A careful selection of cases should be applied due to limited evidence regarding the long-term evaluation of this restorative technique 4
Key Considerations
- The endocrown serves as a suitable alternative to the conventional post-core restoration and full-coverage restoration 5
- The endocrown promotes the stability and retention of the indirect restoration without the need for a cast metal core or reconstruction with intracanal post 5
- The endocrown is a reliable alternative to post-retained restorations for molars and seems promising for premolars 3
- The clinical performance of endocrown restorations can be satisfactory with the use of resin composite or glass ceramic and hybrid materials 4
