AIM To assess the influence of silane evaporation procedures on bond strength between a dental ceramic and a chemically activated resin cement. MATERIALS AND METHODS Eighteen blocks (6 mm Chi 14 mm Chi 14 mm) of ceramic IPS Empress 2 were cemented (C and B) to composite resin (InTen-S) blocks using a chemical adhesive system (Lok). Six groups were analyzed, each with three blocks divided acco...

statement of problem: mechanical failure of ceramic materials is controlled by brittle fracture, mostly occurred in tension. in 3-unit all-ceramic fpds the connector area is considered to be at fracture risk because of tensile stress concentrations. purpose: the aim of this fe analysis was to evaluate the effect of taper on stress distribution in all-ceramic fpds. materials and methods: in this...

Thermotherapy and chemotherapy in vitro were applied to eliminate Apple chlorotic leaf spot virus (ACLSV) and Prunus necrotic ring spot virus (PNRSV) from myrobalan (Prunus cerasifera var. divaricata Borgh.), PNRSV from ‘Empress’ plum (Prunus domestica L.) and Prune dwarf virus (PDV) from ‘Early Rivers’ sweet cherry (Cerasus avium (L.) Moench.) plants. ELISA assays conducted one year after ther...

The aim of the study was to evaluate effect self-etching silane primer on long-term bonding strength feldspathic ceramic. Ceramic blocks (IPS Empress CAD, Ivoclar Vivadent) were cut with a low-speed diamond disk (Isomet 1000, Buehler) into 40 12x7x6mm, under water cooling, and randomly divided two groups (n=20), according surface conditioning: hydrofluoric acid (HF) (Condac, FGM) or (MEP) (Mono...

Background: The quest for newer and stronger materials replacing teeth has resulted in Zirconium oxide's introduction, which possesses excellent mechanical strength toughness. However, uncertainty exists the relationship between its bond surface treatment method adopted mode of failure at interface. Aim - study aimed to evaluate comparison micro-tensile zirconia core all-ceramic layering with d...
