520 _aAim: The purpose of this (in vitro) study is to evaluate the fracture resistance of cerasmart and Celtra Duo endocrowns compared to endodontically treated teeth restored with glass fiber post and lithium disilicate crowns. Methodology: eighteen sound maxillary premolars were endemically treated. Group (GE) received fiber post, resin core and (IPS E.max CAD, Ivoclar-Vivadent) crown. Group (GC) received endocrown with butt joint finish line design fabricated from (CERASMART, GC Dental USA). Group (GD) received an endocrown with butt joint finish line design fabricated from zirconia reinforced lithium disilicate (CELTRA DUO, Dentsply Sirona).All restorations were fabricated using (CEREC MC XL SW 4.0) and cemented with self-adhesive dual cure cement Results: Fracture resistance test show that there was statistically significant difference between the three groups (P-value = 0.001, Effect size = 0.603).Conclusion: Conventional post, core and conventional crown treatment option remains the gold standard for treating endodontically treated maxillary premolar, nevertheless endocrown restorations on premolars needs further research for being a viable restoration in this condition
