  • Orthodontic appliance adhesive
    Patent number: 5008304
    Abstract: An orthodontic appliance adhesive has a plurality of glass spheres maintained therein. The glass spheres are coated with a release agent which repels the resin of the adhesive, causing the glass spheres to define effective voids within the adhesive when it is cured. These voids facilitate fracture of the adhesive composite. The beads further provide for a uniform spacing between an orthodontal bracket and a tooth when the adhesive is used for such bonding.
