Zirconia endocrown with intracanal extension and zirconia posts on maxillary molars: in silico study.

Within the limitations of the study, zirconia endocrowns with intracanal extension exhibit more favorable stress distribution in both restoration material and dentin compared to zirconia posts and pulpal extension endocrowns. These findings suggest that endocrown with intracanal extension may be a better restorative option for reducing stress. (Quintessence Int 2025;56:120-129; doi: 10.3290/j.qi.b5798352).
