An In Vitro Study of Retention and Marginal Adaptation of Endocrowns With Different Intracoronal Depths.

Within the limitations of this study, we found that different materials and intracoronal depths can indeed influence the retention of CAD/CAM fabricated endocrowns. Based on the controlled setting findings, PICN was found to have better retention and better marginal adaptation than similar lithium disilicate premolar endocrowns.
