COLOR SCHEMES AND BIOCOMPATIBILITY OF EPOXY RESIN/POLYTETRAFLUORETHYLENE COAT ON THE SURFACE OF TINIARTH WIRES

摘要：

In order to avoid the metallic smile appearance of metal wires when undergoing orthodontic treatment, epoxy resin/polytetrafluorethylene coating TiNi arch wires were made by dipping method. TiO2 and FeFe2O4 were chosen as dyes in order to match the color of teeth and the color schemes were fixed by spectrophotometer method. The biocompatibility of coating was also examined. The results showed that the cytotoxicity of the coating was grade I, and without mutagenesis and carcinogenesis. Skin sensitization assay showed no erythema or oedema response and epithelial was integrated according to mucous membrane irritation. Thus, good behavior in clinic can be anticipated.
