In this perspective, endocrowns can be considered as a feasible alternative for post-core restorations. Objective To evaluate the clinical efficiency of CAD/CAM resin nano ceramic endocrowns in restorating posterior teeth. Case description A 37-year-old man who reported a chief complaint of pain was referred for treatment. After clinical and radiographic examination: three endocrowns was planned for the rehabilitation of the teeth number 14, 25, 26. The endocrowns were scanned and designed by using CEREC 3D software and milled from a CAD/CAM resin nano ceramic block. At one-year follow-up, no cracks, caries or decementation of the endocrowns was seen. Practical implications Endocrowns seems as a successful treatment technique as an alternative to post-core supported crowns in restoring the posterior teeth. CR - Linn J, Messer HH.
