They also exhibit excellent aesthetic outcomes, and life-like translucency. Moreover, glass ceramics can provide better adhesion to the underlying tooth preparation, compared with metal-bonded ceramics and oxide ceramics. This is achieved by application of HF etching and silanization, followed by bonding with resin cement. The resin cement is applied as the means to provide a seal, adhesion and 'filler' in the small space that exists between a restoration and prepared tooth. These unique properties have given rise to expanded restoration designs for glass ceramics in comparison to other ceramics, e.g., veneers, inlays or onlays. Hence, durable and stable adhesion is strongly required for the long-term success of these restorations. The aim of this project was to evaluate the durability of adhesion between CAD/CAM ceramics and resin cements as well as the effect of different factors on long-term ceramic adhesion. In the first experiment, two bonding models were compared and contrasted using a microtensile bond strength test. Two surface treatments and two resin cements were also examined. Ceramic to ceramic, as a bonding model, was found to be better than a ceramic to resin composite model. Surface treatments and resin cements had a significant effect on the microtensile bond strength. The second experiment aimed to evaluate the stability of long-term adhesion using six resin luting cements when bonded to three different CAD/CAM ceramics in water over 12 months. According to the outcomes of this study, VITA Suprinity(R) and VITA Enamic(R) demonstrated better long-term adhesion compared to IPS e.max(R) CAD. Furthermore, the microtensile bond strengths of ceramic and resin cement decreased up to 3 months but thereafter became relatively stable. Different resin cements showed different bonding behaviour during prolonged storage time. The third study examined the effect of two etching times on long-term ceramic adhesion and the effect of six resin luting cements on durability of adhesion. This study indicated that prolonged etching time could increase the microtensile bond strength of glass ceramics in the short-term, however, different etching times did not have an obvious influence on the long-term adhesion. In the fourth experiment, an evaluation of sorption, solubility and dimensional change of six resin luting cements immersed in various storage media was undertaken. Significant differences were observed in the sorption, solubility and dimensional change of the cements when exposed to the different storage media over time. The objective of the last experiment was to evaluate the effect of immersion time and media on fracture toughness of six resin cements. It was concluded that fracture toughness varied among the cements and the value decreased over time. Furthermore, the three storage media evaluated in this study seemed to not have had a significant effect on the fracture toughness. It was concluded that, in general, lower sorption, solubility and dimensional change in resin cements seems to produce a higher fracture toughness and microtensile bond strength to glass ceramics.

This book was released on 2014 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective: To assess the effects of ceramic opacity and thickness on delivered radiant exposure and degree of conversion and microhardness of the light-cured resin cement. Materials and Methods: IPS e-Max ceramic discs (Ivoclar Vivadent) were fabricated in 3 thicknesses (0.5, 1.0, and 1.5mm) and 4 opacities (HT, LT, MO, HO) (n=3/per group). Light-cured resin cement (Variolink Veneer Luting Cement - shade MVO, Ivoclar Vivadent) 50μm thick was cured through these ceramics disks using a quartz tungsten halogen curing light unit (Optilux 501, Kerr) with its radiant exposure measured by MARC from a fixed distance (1.5mm). Knoop microhardness was used to evaluate the bottom degree of cure and was correlated with the radiant exposure deliverd. Descriptive statistics were conducted. One- and two-way ANOVA with post-hoc Tukey's HSD test, Pearson correlation test, the simple linear regression analysis were used for the statistical analyses (alpha=0.05). Results: Significant interaction was found between ceramic thickness and opacity on radiant exposure (p=0.0078). Subsequent analyses demonstrated that there was a significant simple effect for opacity and for thickness on radiant exposure under different conditions of thickness and opacity. A significant relationship was found between resin cement microhardness and radiant exposure (p=0.0001) below 4.5 J/cm2. Moreover, the Pearson correlation coefficient of 0.93 indicated a strong correlation between the two variables below 4.5 J/cm2 of radiant exposure delivered. Conclusion: Ceramic opacity and thickness affect the polymerization of light-cured resin cements and need to be considered and compensated for when bonding indirect restorations. Based upon the findings of this preliminary study, the final study is ongoing.

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective: The purpose of this research project is to evaluate and compare the effect of different surface treatments on surface properties. Also the effect of different surface treatments with silane coupling agents on the bond strengths between resin cement and four CAD/CAM lithium disilicate-based glass ceramics (LDGC). Materials and methods: This study had three levels of analyses. Part I: The physicochemical analyses of four CAD/CAM LDGC surfaces. The surface physicochemical compositions of the four LDGC products (e.max CAD, Vita Suprinity, Celtra Duo, n!ce) were analyzed using X-ray photoelectron spectroscopy (XPS). In addition, scanning electron microscopy (SEM) was used to analyze the microstructure of LDGC. Part II: The effect of different surface treatments on the micromorphology and the roughness of four CAD/CAM lithium disilicate- based glass ceramics Atomic force microscopy (AFM) was used to measure the surface roughness and scanning electron microscopy (SEM) was used to analyze the changes in the surface micromorphology. Part III: The effect of an experimental silane coupling agent (TEOS) with different surface treatments on bond strength of four CAD /CAM lithium disilicate-based glass-ceramics. The shear bond strength between the ceramic surface and resin cement was tested using shear bond testing after a 30 day storage in distilled water. Results: The chemical composition percentage on the nano surfaces of the LGGC changed after hydrofluoric acid treatment. Different surface treatments produced different values of roughness. The highest shear bond strength values were found with the use of hydrofluoric acid treatment and the combination of both hydrofluoric acid and sandblasting followed by manufacturer's recommendation of silane coupling application. Conclusion: Surface treatments and silane coupling agents play a significant role to obtain reliable bond strengths between resin cement and LDGC restorations.

Available in PDF, EPUB and Kindle. Book excerpt: This book covers both basic scientific and clinically relevant aspects of dental composite materials with a view to meeting the needs of researchers and practitioners. Following an introduction on their development, the composition of contemporary composites is analyzed. A chapter on polymerization explains the setting reactions and light sources available for light-cured composites. The quality of monomer-to-polymer conversion is a key factor for material properties. Polymerization shrinkage along with the associated stress remains among the most challenging issues regarding composite restorations. A new classification of dental composites is proposed to offer more clinically relevant ways of differentiating between commercially available materials. A review of specific types of composites provides an insight into their key issues. The potential biological issues of dental composites are reviewed in chapters on elution of leachable substances and cariogenicity of resin monomers. Clinical sections focus on material placement, finishing procedures, and the esthetics and clinical longevity of composite restorations. Bonding to tooth tissues is addressed in a separate chapter, as is the efficiency of various composite repair methods. The final chapter discusses future perspectives on dental composite materials.
