چکیده
ABSTRACT Objective: This study assessed whether the use of a silane coupling agent influence bond strength two universal adhesives to ceramic or resin CAD/CAM blocks. Methods: Forty-eight samples were obtained from each nano-ceramic hybrid block (RCBs) and lithium disilicate blocks (LD). Samples treated with MDP (Monobond - S-MDP), without (Prosil PS), no application (Control Ctr) followed by adhesive (UAS) (UA) (n=8). Three polyurethane tubes (1.5 mm internal diameter) positioned in sample surface filled dual cured cement. Bond was microshear test failure analysis performed for all samples. Results: For RCBs, UAS presented highest values (p=0.004). Silane not significant (p=0.444). LD, (p<0.001), but (p=0.066). Failure showed high prevalence failures both substrates. Conclusion: A silane-containing promoted best results block. bonding glass-ceramic material, additional (without MDP) results.

Performance of universal adhesives on bonding to leucite-reinforced ceramic
BACKGROUND This study aimed to investigate the microshear bond strength of universal bonding adhesives to leucite-reinforced glass-ceramic. METHODS Leucite-reinforced glass-ceramic blocks were polished and etched with 9.5% hydrofluoric acid for 1 min. The specimens were assigned to one of four groups based on their surface conditioning (n = 16): 1) NC: negative control with no further treatme...

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
15 صفحه اولHigh-Performance Temporary Adhesives for Wafer Bonding Applications
Myriad structures for stacking chips, power devices, smart cards, and thin substrates for processors have one thing in common: thin silicon. Wafer thinning will soon be an essential process step for most of the devices fabricated and packaged henceforth. The key driving forces for thinned wafers are improved heat dissipation, three-dimensional stacking, reduced electrical resistance, and substr...

In vitro tensile bond strengths were determined for three adhesive cements and two resin-bonded bridge cements to two alloys, each prepared by two methods: sandblasted Ni-Cr-Be alloy (I), electro-etched Ni-Cr-Be alloy (II), sandblasted Type IV gold alloy (III), and tin-plated Type IV gold alloy (IV). Storage conditions of 24 hours at 37 degrees C and 30 days at 70 degrees C were evaluated. The ...
