• Effect of Irradiation Time on Bond Strength of Metal Brackets Bonded with Light-cured Resin.

抄録

When orthodontic metal brackets are bonded to tooth surface with light-curing resin in direct-bonding technique, the light irradiated from the photo-curing unit could not reach directly to the resin under the bracket due to the opacity of metal bracket. Then, to clarify its influence, the author investigated the effects of irradiation time on the degree of conversion of the resin cured under the metal bracket and already reported. The purpose of this study was to evaluate the effect of degree of conversion of bonding resin to bond strength of metal brackets.<BR>The bond strength of metal brackets bonded to bovine enamel with light-curing resin were determined with increase of irradiation time. The bond strength increased proportionally with increase of irradiation time up to 40sec, but did not vary remarkably beyond 40 sec. This result was similar to the variation of degree of conversion of resin cured under metal bracket with increase of irradiation time. There was a strong positive correlation between the bond strength and the degree of conversion of bonding resin.
