Here, the development of an adhesive is reported - generated via free radical polymerization - which can be degraded upon thermal impact within minutes. The degradation is based on a stimuli responsive moiety (SRM) that is incorporated into the network. The selected SRM is a hetero Diels-Alder (HDA) moiety that features three key properties. First, the adhesive can be degraded at relatively low...

PURPOSE The purpose of this study is to report retrospectively the clinical results of cast metal slot-retained resin-bonded fixed dental prostheses (RBFDPs) used in the restoration of single missing second premolar teeth, as this kind of prostheses provides acceptable clinical outcomes in a minimally invasive and esthetic treatment for the average patient requiring cheaper and faster treatment...

A multi-level analysis of skin/stiffener debonding is used to perform the design of fuselage of future aircraft during postbuckling. The “pyramid of test” approach is used both for experimental and numerical analysis (see Fig 1). The analysis begins with nonspecific element (NASA Specimens), then 7 point-bending tests are performed and the approach is finally validated on real panels of an on-g...

Concrete-epoxy interface can be found in many strengthened or retrofitted structures, especially in Hong Kong where concrete structures are the majority. In practice, epoxy is usually used in repairing concrete structures because of its excellent adhesion, chemical and heat resistance, good mechanical properties and electrical insulating properties. The bond between concrete and epoxy has been ...

Peel-and-stick process, or water-assisted transfer printing (WTP), represents an emerging process for transferring fully fabricated thin-film electronic devices with high yield and fidelity from a SiO2/Si wafer to various non-Si based substrates, including papers, plastics and polymers. This study illustrates that the fundamental working principle of the peel-and-stick process is based on the w...

Introduction: Debonding pain is an unpleasant sensation that frequently encountered during debonding procedure.
 Aim of the study: To investigate effectiveness cotton roll-biting on caused by Materials and methods: 102 patients (61 females, 41 males) who were at stage in orthodontic treatment included research. The study was planned using a split-mouth design: one side jaw study, other con...

PURPOSE The objective of the present study is to evaluate the effects of Er:YAG laser debonding of ceramic brackets on the bond strength and the amount of adhesive resin remnant. MATERIALS AND METHODS Twenty human mandibular incisors were randomly divided into two groups of 10 and polycrystalline ceramic brackets (Transcend series 6000, 3M Unitek, Monrovia, CA, USA) were bonded on enamel surf...
