A patient came to my clinic with previously broken teeth but one of them was very controversial. 
Is it restorable or not?.  After a thorough diagnosis,  I decided to restore it with an all-ceramic post and core that can be used in combination with all-ceramic crowns to prevent the unesthetic metal display if a cast-metal post and core was used in such case.  

  • It is highly biocompatible 
  • increases the translucency of an all-ceramic restoration
  • with good modulus of elasticity.



Preoperative situation

Occlusal view

Diagnostic wax-up

Esthetic pre-evaluative temporaries

Caries removal 

Post space reparation immediately before taking impreesion

Pressed lithium disilicate post & core


Poreclain etchant application

Resin cement

Inserted under gentle pressure to allow escapement of excess cement 

Application of glycerin gel to complete light-curing

Esthetic crown lengthening




Temporization two days after the surgical procedure with the margins short of the gingiva

Two months recall after surgery

Intial teeth preparation then the final impression was delayed 

Tissues maturation .. 4 months recall

Preparation just before registering the final impression


Final restorations
Layered lithium disilicate crowns 

Absolute isolation to start the procedure of adhesive cementation 

Two different types of etchants; the red one is porcelain etchant for the ceramic core part
the blue is phophoric acid 37%

The phosphoric acid was applied for an extended time to achieve good etching for this part of sclerotic dentin.

Ethed substrate

Bonding agent application


Glycerin gel to complete light-curing


Final cementation after 6 months.



Finally it was survived.. New tooth, new life
