    Author(s): Alaa H Abbas* and Zainab M Abdulameer

    Purpose: The aim of this in vitro study was to evaluate the effect of different restoration designs on fracture strength and failure mode of endodontically treated upper first premolar with mesio-occluso-distal (MOD) cavity. Material and methods: Forty sound maxillary first premolars were divided into 5 groups (n=8): GA (intact group), GB-E (test groups). In tested groups, all the teeth were received MOD cavities and endodontically treated. GB: Endodontically treated teeth (ETT) restored with direct composite resins (Filtek™ Bulk Fill Posterior Restorative, 3M ESPE). While teeth in groups (C, D and E) were prepared to receive indirect ceramic restorations made from lithium disilicate material (IPS E-max CAD, Ivoclar-Vivadent). GC: ETT restored with overlays. GD: ETT restored with conventional crowns. GE: ETT restored with endocrowns. The indirect restorations were made by CAD/CA.. Read More»
