[Application of custom casting separate post-and-core crown restorations of titanium in molar defects with low
Purpose:
To evaluate the clinical effect of custom casting separate post-and-core crown restorations of titanium in residual molar roots and crows with low occlusogingival distance.
Methods:
Twenty-two residual roots and crowns with low occlusogingival distance were involved in the study. The root canals were prepared according to their natural directions without concerning about the common path of insertion and then the preparation of abutment teeth were made following the routine clinical procedure. Accurate impression was taken with silicone to fabricate the custom casting separate post-and-core crown restorations of Ti. The two parts were cemented together with resin cement.
Results:
All the 22 fixed restorations were found to be with good retention and without looseness, falling off or breaking off of the roots.They all used normally for 6-30 months.
Conclusions:
Custom casting separate post-and-core crown of Ti is a better prosthetic restoration for molar residual root and crown with low occlusogingival distance.
