One Year Clinical Evaluation of E-max CAD Versus Cerasmart Endocrowns in Anterior Endodontically Treated Teeth

Nowadays Endocrowns are classified as conservative treatment modality for restoration of Endodontically treated teeth in which pulp chamber is used as a retentive resource. With the advancement in technology in the field of adhesive dentistry its use is increasing day by day in clinical practice. Acid Etchable ceramics such as lithium Disilicate based ceramics are the gold standard ceramic material used for Endocrowns. The Etchable property and the translucent character of lithium Disilicate enhance strength and esthetic property. A new material CERASMART (Force Absorbing Flexible nano ceramic CAD/CAM block) contain high density of ultrafine glass particles with 71 wt% filled nano-composite. It combines high strength and unique aesthetics. full homogeneous and even distribution of nano ceramic network lead to unique physical properties for cerasmart . Uniform scuttle (very short inter-particle distance) of silanated and bonded particles is key to delivering CERASMART's™ with high strength and acceptable level of marginal adaptation. So, it can perfectly use in posterior, anterior, inlay, onlay, and implant restorations and also enables minimum tooth reduction for more conservative restoration. Awad et al (1) found that Cerasmart showed significantly higher flexural strength and modulus of elasticity, with lower flexural modulus values compared to other groups. Also, result in smoother margins compared with other types of ceramic. So, present research will evaluate patient satisfaction, bonding properties and marginal adaptation
