Restoration of Severely Damaged Tooth by Zirconia based Endocrown: Case Series.

Following endodontic (root canal) treatment, teeth loss their mechanical properties, and the teeth become fragile because of the removal of pulp and dentin. Hence, prosthetic restoration of root canal-treated teeth is a challenge. Endocrown is a single restoration, and it is considered an excellent alternative restoration for teeth with large coronal destruction and root canal treatment difficulties. Zirconia endocrowns are reliable materials for root canal-treated molars with extensive loss of crown structure. This case series presents four cases of restoration of severely damaged molars presenting various symptoms and prosthetic restorations were done by zirconia-based endocrown. The prognosis in all patients was good.
