ABSTRACT:
An improved orthodontic dental bracket with glue openings in the form of notches in the edges of the base plate or apertures in the interior of the base plate of the bracket. The openings can have outwardly diverging side walls. During application of the bracket the glue openings serve to direct dental adhesive to flow into the openings and induce the adhesive to form an enlarged head toward the outer surface of the bracket's base plate. Once the glue has cured, the column of glue and enlarged head provides a positive mechanical lock to further secure the dental bracket to the glue layer.
