Comparative Study of Microleakage of Full Crown Resterations Luted with Ariadent and Harward Zinc Phosphate Cements
Film thickness, strength, solubility and microleakage of dental cements are essential factors in cement selection by dentist. Since failure of metal ceramic restorations is mostly due to their marginal leakage and provious studies have shown that microleakage of Resin, Glassionomer and Zincphosphate cements are different, this study was done to compare the rate of microleakage between Ariadent ...
متن کاملComposite resin vs resin cement for luting of indirect restorations: comparison of solubility and shrinkage behavior.
The aim of this study was to evaluate relationship between shrinkage development and early solubility of two commonly used luting materials, a self-adhesive cement (GCem chemical and light cured) and composite resin (Tetric). Linear displacement, shrinkage forces and leaching of UDMA from specimens immersed in 75% ethanol/25% water were measured. The least amount of linear shrinkage (33.0±2.9 µ...
متن کاملEffect of adhesive luting on the fracture resistance of zirconia compared to that of composite resin and lithium disilicate glass ceramic
OBJECTIVES The purpose of this study was to evaluate the effect of adhesive luting on the fracture resistance of zirconia compared to that of a composite resin and a lithium disilicate glass ceramic. MATERIALS AND METHODS The specimens (dimension: 2 mm × 2 mm × 25 mm) of the composite resin, lithium disilicate glass ceramic, and yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) were p...
متن کاملEffect of thermocycling on the bond strength of a glass-infiltrated ceramic and a resin luting cement.
The aim of the present study was to evaluate the effect of thermocycling on the bond strength between the surface of the glass-infiltrated alumina ceramic In-Ceram (VITA) and the Panavia F resin cement (Kuraray CO.). Four 5x6x6mm In-Ceram blocks were obtained. One of the 6x6mm faces of each block was conditioned with Cojet - System (tribochemical silica coating, ESPE-3M) and then luted under a ...
متن کاملRetentiveness of dental cements used with metallic implant components.
There is limited dental literature evaluating the retentive capabilities of luting agents when used between metal components, such as cast metal restorations cemented onto machined metal implant abutments. This study compared the retentive strengths of 5 different classes of luting agents used to cement cast noble metal alloy crowns to 8-degree machined titanium cementable implant abutments fro...
متن کاملIn vitro tensile strength of luting cements on metallic substrate.
The aim of this study was to determine the tensile strength of crowns cemented on metallic substrate with four different types of luting agents. Twenty human maxillary molars with similar diameters were selected and prepared to receive metallic core castings (Cu-Al). After cementation and preparation the cores were measured and the area of crown's portion was calculated. The teeth were divided ...
