Apparatus for precisely locating an orthodontic bracket at a predetermined position on a surface of a tooth

Claim 1

An apparatus for transferring an orthodontic bracket to a precisely predetermined position on a surface of a tooth, said apparatus comprising: a first means for suspending the orthodontic bracket, wherein said first means is configured for engaging a holding member of the orthodontic bracket that is to be ligated; a second means for securing the orthodontic bracket with said first means, said orthodontic bracket being capable of being separated from said first means by said second means; and a third means adapted for fitted placement on an upper area of the tooth and for stably supporting said first means so as to enable the orthodontic bracket assembled with said first means to be precisely located at the predetermined position on the surface of the tooth.

Claim 2

An apparatus for transferring an orthodontic bracket to a precisely predetermined position on a surface of a tooth, said apparatus comprising: a first means for suspending the orthodontic bracket, wherein said first means is configured for engaging a holding member of the orthodontic bracket that is to be ligated; a second means for securing the orthodontic bracket with said first means, said orthodontic bracket being capable of being separated from said first means by said second means; and a third means adapted for fitted placement on an upper area of the tooth and for stably supporting said first means so as to enable the orthodontic bracket assembled with said first means to be precisely located at the predetermined position on the surface of the tooth.

Claim 18

An apparatus for transferring an orthodontic bracket to a precisely predetermined position on a surface of a tooth, the orthodontic bracket including a base member having an adhesion surface to be adhered to the surface of the tooth, and a holding member and a hook respectively integrated with the base member, the holding member holding an orthodontic wire to be ligated by the orthodontic wire for correcting irregular set of teeth, said apparatus comprising: a suspension body adapted to extend in parallel with the tooth from an apex toward a dental not of the tooth with a predetermined gap, said suspension body having an inner surface, at a lower end of which a filling recess is formed, and an outer surface, on a lower portion of which a groove is formed, said fitting recess having a contour complementary to a contour of the holding member for filled insertment of the holding member in said filling recess; a ring inserted in said groove and hooked around the hook after the holding member has been inserted in said fitting recess, to thereby tightly assemble said suspension body and the orthodontic bracket together; and a molding spacer disposed between said suspension body and the tooth, which has first and second surfaces respectively facing the tooth and said suspension body, said first surface of said molding spacer having a contour complementary to a contour of the upper area of the tooth, said contour of said first surface of said molding spacer for fitted placement of said molding spacer on the upper area of the tooth, which includes an apex and upper portions of a labial surface and a lingual surface of the tooth, said second surface of said molding spacer having a contour complementary to a contour of said inner surface of said suspension body, said contour of said second surface of said molding spacer for fined engagement of said molding spacer with said suspension body.

Claim 19

An apparatus for transferring an orthodontic bracket to a precisely predetermined position on a surface of a tooth, the orthodontic bracket including a base member having an adhesion surface to be adhered to the surface of the tooth, and a holding member and a hook respectively integrated with the base member, the holding member holding an orthodontic wire to be ligated by the orthodontic wire for correcting irregular set of teeth, said apparatus comprising: a suspension body adapted to extend in parallel with the tooth from an apex toward a dental not of the tooth with a predetermined gap, said suspension body having an inner surface, at a lower end of which a filling recess is formed, and an outer surface, on a lower portion of which a groove is formed, said fitting recess having a contour complementary to a contour of the holding member for filled insertment of the holding member in said filling recess; a ring inserted in said groove and hooked around the hook after the holding member has been inserted in said fitting recess, to thereby tightly assemble said suspension body and the orthodontic bracket together; and a molding spacer disposed between said suspension body and the tooth, which has first and second surfaces respectively facing the tooth and said suspension body, said first surface of said molding spacer having a contour complementary to a contour of the upper area of the tooth, said contour of said first surface of said molding spacer for fitted placement of said molding spacer on the upper area of the tooth, which includes an apex and upper portions of a labial surface and a lingual surface of the tooth, said second surface of said molding spacer having a contour complementary to a contour of said inner surface of said suspension body, said contour of said second surface of said molding spacer for fined engagement of said molding spacer with said suspension body.
