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.

Download or read book Bond Strength Evaluation of Two Resin Cements with Two Adhesives and Analysis of Mode of Failure written by Preethi Mohan and published by . This book was released on 2009 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cementing of indirect restorations with resin cements generally requires the pre-treatment of dentin with an adhesive. When dual-cured or chemical-cured resin cements are used with these single-step adhesives, incompatibility issues exist. This has resulted in manufacturers making chemical changes in their products. Kerr Dental markets a new resin cement, Nexus Third generation (NX3), which utilizes a proprietary redox system different from the second generation of composite luting agent (NX2). The aim of this study was to evaluate microtensile bond strength and mode of failure of NX3 and NX2 with two different adhesive systems (total-etch and self-etch) after 1 week and after 3 months of storage. Methods: Sixty-four non-carious teeth were sectioned to expose the dentin using a low-speed saw. Dentin surfaces were ground with 320-grit SiC paper. The adhesives Optibond Solo Plus (SOL), and Optibond All In One (AIO) were applied, and resin cements (NX2, NX3) were used to lute 4-mm composite discs to the treated dentin surfaces. Microtensile bond strength was determined at 1 week (IM) and after 3 months (3MON) of storage using a universal testing machine (MTS). All specimens were examined under the stereomicroscope to determine the mode of failure. Random specimens from each failure group were examined using scanning electron microscopy. Statistical Analysis: Comparisons between the treatment combinations for differences in microtensile bond strength were performed using Weibull-distribution survival analysis. Comparisons between the treatment combinations for differences in the failure mode were performed using Fisher's Exact tests. The group NX3 SOL IM (30.5 MPa) had significantly higher bond strength than NX3 SOL 3MON (13.4 MPa); NX3 AIO IM (11.3MPa); NX3 AIO 3MON (8.2 MPa; NX2 AIO 3MON (5.8 MPa); NX2 SOL IM (6.3 MPa), and NX2 SOL 3MON (3.2 MPa). The group NX2 AIO IM (19.3 MPa) was not significantly different from NX3 SOL IM. The group NX2 SOL 3MON and group NX2 SOL IM had a significantly higher percentage of teeth with mixed failure than all of the other groups. None of the other groups had significantly different failure mode. The group NX3 SOL IM had 90-percent beam survival beyond 17 MPa, and NX2 AIO IM had 50 percent of beams surviving beyond 17 MPa, a better performance. For all the other groups, more than 50 percent of beams failed below 17 MPa. Results show high evidence of degradation for all groups considered in this investigation. The use of these types of cement adhesive combinations in clinical situations should be used with this understanding.

Download or read book Extra Coronal Restorations written by Robert Wassell and published by Springer. This book was released on 2018-07-31 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a state of the art clinical guide to contemporary materials and techniques for the restoration of individual teeth and implants. It fully reflects the important developments in the field over the past 15 years, including in particular the shift away from wholesale use of crowns towards adhesive dentistry and less invasive extra-coronal restorations. The book opens by considering the principles and evidence base relating to the longevity of restorations of teeth and implants. Importantly, it explains how to ensure “a healthy start” and manage future risks. Material choice and aesthetic issues are then discussed, before all aspects of the planning and provision of extra-coronal restorations are examined in depth. The coverage also includes the adaptation of crowns to existing partial dentures. In line with modern dental education, each chapter begins with clinically relevant learning objectives, and helpful clinical tips are highlighted. The book will be of value for senior dental undergraduates, postgraduates, and practicing dentists and its scientific content will be of interest to dental academics.

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.
