Metal-resin bonding mediated by epoxy monolith layer

Spark erosion as a metal-resin bonding system.

PURPOSE Resin to metal bond strength of two commercial and one experimental metal-resin bonding system for crown and bridge veneer composites was evaluated. MATERIALS AND METHODS All specimens were prepared and tested according to ISO 10477 Amendment 1. A high precious alloy (HPA), a Co/Cr-alloy (Co/Cr) and pure titanium (Ti) were wet-ground to a final surface finish of 800 grit and air-dried...

Cellulose whisker/epoxy resin nanocomposites.

New nanocomposites composed of cellulose nanofibers or "whiskers" and an epoxy resin were prepared. Cellulose whiskers with aspect ratios of approximately 10 and approximately 84 were isolated from cotton and sea animals called tunicates, respectively. Suspensions of these whiskers in dimethylformamide were combined with an oligomeric difunctional diglycidyl ether of bisphenol A with an epoxide...

AMTS-SWP-0021-A-Bonding and filling using Laminating Epoxy Resin

Clinical experince with an epoxy resin adhesive for direct bonding of orthodontic attachments.

An epoxy resin formulation developed in the Dental Research Unit has been subjected to further clini­ cal trials. Six patients, were used in the study. They were divided into two age groups and all the teeth, including the first molars, bonded. Rubber dam was used to keep the crowns dry during the setting period o f the resin. In the younger group the mean failure rates were 27 per cent fo r an...

Assessment of cross-reactivity of new less sensitizing epoxy resin monomers in epoxy resin-allergic individuals.

BACKGROUND Measures to prevent occupational exposure to epoxy resins, including education, medical examination, and voluntary agreements between employers and workers, have not been effective enough to protect against skin sensitization. Therefore, alternatives to the major epoxy resin haptens that have been found to be less sensitizing in the local lymph node assay have been developed. OBJEC...
