The Bonding of Orthodontic Attachments Using a Visible Light Cured Adhesive

Abstract

The bonding of orthodontic attachments using a visible-light cured adhesive is described. The material is a Urethane Dimethacrylate resin with a glass filler which sets when exposed to visible light. This gives the material the advantage that the operator can decide when the material should set. This command setting at the appropriate moment gives increased working time and improves the accuracy of bracket positioning. These properties have been used in the development of a new technique for the direct placing of bonded retainers.
