This book was released on 2016 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: All-ceramic restorations have excellent esthetic outcomes compared with other restorative materials. Lithium disilicate is classified as one of many silica-based all-ceramic materials. Currently, companies have provided single-step adhesives, known as universal adhesives, compatible with different restorative materials including lithium disilicate. Many studies have reported greater bond strengths when using a silane to treat the lithium disilicate before applying the bonding agent. Moreover, few studies were published comparing the bond strength when using the universal adhesive alone. Purpose: The objective of this study was to evaluate and compare shear bond strength of three universal adhesives to lithium disilicate ceramic restorative material. Materials and Methods: Three universal adhesive bonding agents were selected from commercially available adhesives. 408 IPS e.max CAD ceramic discs were processed, fired, and etched for 20s. The specimens were divided into six groups. The first three groups used the universal adhesive directly. The remaining three groups were treated with silane. Then, a composite resin cylinder was placed on top of the adhesive using a bonding jig. Each group was subdivided into four equal subgroups (n = 17), subjected to different aging simulation procedures: 24 h, one month with 5000 thermocycles, two months with 5000 cycles, and three months with 5000 cycles. Then, specimens were debonded using shear force by a universal testing machine (MTS). Results: Shear bond strength was greater with silane than without silane (p

Available in PDF, EPUB and Kindle. Book excerpt: The evolution of orthodontic materials in the past 5 decades has been a unique progress curve characterized by periods of intense activity with many developments followed by long quiescent intervals. An example of the delay in adopting the advances in dentistry might well be illustrated by the acid-etching technique, which was introduced in the mid 1950s1 and became universally accepted in the 1960s. It took more than a decade for this practice to become standard procedure in orthodontics on a large scale. Infact, orthodontic bonding has advanced more in last 10 years than previous 25. In the past decade, we have witnessed unprecedented progress in bonding to enamel with various materials techniques and auxiliaries involving glass ionomer bonding, self-etching primers, and new, powerful light-curing sources, along with self-ligating brackets and a different treatment concept, the Invisalign technique.

This book was released on 2024-10-09 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Teeth and bones are typical hard tissues in vertebrates. Due to hierarchical structural characteristics and excellent mechanical properties, hard tissues play important roles in the human body, such as health protection, movement support, and food mastication. Once hard tissue defect occurs, our living quality will be seriously affected. In general, hard tissues lack the ability to self-repair, except for the regeneration ability of bone for small-scale defects. As a result, the past few decades have witnessed great progress in the field of biomaterials for hard tissue repair. Actually, both teeth and bone are masterpieces of biomineralization in nature, the repair and regeneration of hard tissues should be performed in a biomimetic way, either by using a biomimetic mineralization strategy or biomimetic materials.

Whitlock and published by . This book was released on 1992 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to compare the bond strengths of three adhesive systems (two-paste, no-mix, and one light-activated) when used alone and combined with a porcelain priming agent to bond ceramic brackets to porcelain surfaces. Sixty porcelain specimens were randomly assigned to the six different treatment groups. One half of the groups were bonded with the porcelain priming agent and one of the adhesive systems and the other half with one of the adhesive systems without the priming agent. The shear bond strengths, expressed in megapascals (MPa), of all specimens were tested, using an Instron testing machine, 10 minutes after being bonded. The surface of the porcelain and the bracket base were examined, using the scanning electron microscope (SEM), to determine the bond failure patterns and check the prcelain surface for the presence of cracks and fractures. Across the three different adhesive systems, mean shear bond strength measurements ranged from 6.3-7.5 MPa when the porcelain primer was used and from 1.8-3.8 when the porcelain primer was not used. There was a statistically significant difference within each adhesive between those samples with the priming agent (mean shear bond strength of 6.5 ± 0.8, 7.5 ± 1.0, and 6.3 ± 1.2) and those without the priming agent (mean shear bond strength of 3.8 ± 0.4, 1.8 ± 1.8, nad 2.6 ± 1.3) (p ≤ 0.5). Differences between the three adhesives were not statistically significant (p ≤ .05). Evaluation of the bond failure sites, using the SEM, revealed failures at the porcelain-adhesive interface, within the adhesive and at the bracket-adhseive interface for the porcelain primer samples. The samples that were bonded with the different adhesives only displayed a failure exclusively at the porcelain-adhesive interface. The failure patterns were verified by qualitative energy dispersive x-ray analysis (EDS). It can be concluded from this study that using any of the three adhesive systems combined with the porcelain priming agent will provide sufficient bond strength to withstand normal orthodontic forces and not damage the surface of the porcelain when debonded.
