Introduction A great number of techniques have been used for bonding orthodontic brackets to the tooth surfaces. Glass ionomer cements are frequently used material for this purpose. The aim of this study was to measure the shear bond strength of orthodontic brackets bonded with glass ionomer cement Ortho Fuji LC and remained adhesive on the enamel surface after brackets debonding. Material and ...

This paper presents a simple, low-cost, and reliable process for the fabrication of a microfluidic Fabry–Pérot cavity in a Pyrex glass substrate. The microfluidic channels were etched in HF solution on a glass substrate using a Cr/Au/photoresist etching mask resulting in a channel bottom roughness of 1.309 nm. An effective thermocompressive gold–gold bonding technique was used to bond the photo...

We prepared a prosthesis for the replacement of the lumbar vertebrae of sheep, using apatite- and wollastonite-containing glass-ceramic. The material is stronger than human cortical bone and has the special feature of chemical bonding to bone. Ten sheep underwent replacement of L3 and L4 vertebrae, without bone grafting. The animals were killed at intervals from three months to 27 months after ...

The study of wafer level hermetic bonding using sub-micron gold particles with the mean diameter of 0.3_m was conducted at bonding temperature of 150 – 300 °C with varying bonding pressure in the range of 50 – 100 MPa. 4.5 mm-square, 10 μm – 100 μm-wide seal line patterns of sub-micron Au particles were formed on Si or glass wafers by means of wafer level processing using photolithography and s...

Apatite-wollastonite (A-W)-phlogopite glass-ceramic is considered to be difficult to resorb, but often, it has been incorporated in particulate form to create new bioactive composites for potential maxillofacial applications. With various compositions, the present work has attempted to prepare apatite-wollastonite (A-W)-phlogopite glass ceramic composites, by applying sintering. Here, three-poi...
