This in vitro study compared the shear bond strength (SBS) and adhesive remnant index (ARI) of two systems for bonding orthodontic brackets to enamel. The first system involved a self-etching primer (Beauty Ortho Bond, BO) containing surface pre-reacted glass filler. The second involved a primer applied with phosphoric acid etching (Transbond XT, TX). Ninety-six extracted human premolars were d...

We investigate TMMF photopolymer as a cost-efficient alternative to glass for the leak-tight sealing of high-density silicon microchannels. TMMF enables low temperature sealing and access to structures underneath via lamination and standard UV-lithography instead of costly glass machining and anodic bonding. TMMF is highly transparent and has a low autofluorescence for wavelengths larger than 4...

Photoactivated bis-diazopyruvamide-N,N'-bis(3-diazopyruvoyl)-2,2'-(ethylenedioxy)bis-(ethylamine), (DPD)-was previously shown to bond materials containing type I collagen. However, tensile strength of bonded collagenous tissue ( approximately 78% water) was low compared with that of dehydrated collagenous gelatin ( approximately 14% water). Here we investigated the role of water in corneal tiss...

The purpose of this study was to compare the clinical performance of a resin-modified, self-cured glass ionomer adhesive for bonding cast splint Herbst appliances to that of a conventional composite resin in a split-mouth design. Ten patients (six females and four males) with cast splint Herbst appliances were followed for a mean period of 791 months. The performance of 40 cobalt-chromium cast ...

As powder bed based additive manufacturing (AM) is gaining more traction in the research and industry, significant efforts are made to expand capability of AM combining different materials. Conventionally, multiple materials, sealants processes necessary order join metal glasses assemblies. The development a single-step process for vacuum-tight strong bonding between glass could drastically red...

This paper presents the study of gold/gold thermocompression bonding at silicon wafer level. The first samples contains sealing rings and electrical pads, and are characterized on pull, and shear test showing bond strength similar to silicon/glass anodic bonding (10MPa-80MPa). A sealed cavity and a piezoresistor on a 30μm-thick silicon membrane are added in the second samples. Helium test, memb...

Introduction: The aim of the present study was to evaluate the effect of glass ceramic insert in the sandwich technique to reduce microleakage in class II composite resin restorations. Methods: Sixty sound human upper second premolars were selected and randomly divided into six groups (n=10). Class II boxonly cavities were prepared in distal aspects of each tooth with gingival margin located ap...
