Definitions

  • the band of the present invention has relatively thin interproximal portions as compared with the thickness of the remainder of the band.
  • the interproximal portions of the band are thinned, for example, by a grinding action which is accompanied by a simultaneous hardening of the metal in the band, so that no loss of strength is encountered.
  • the thinned interproximal portions of the band facilitates the fitting of the band over the tooth, since unlike the prior art tooth bands, no substantial tooth separation is required.
  • the interpoximal or mesal and distal sides of the band are thinned, this being achieved by a mild grinding action, for example, by the machine described in the copending application Ser. No. 751,555, filed Aug. 9, 1968.
  • the resulting thinning of the band in these areas is accompanied by a simultaneous hardening of the metal in the band at the areas being ground, so that no loss in strength is encountered.
  • This work-hardening effect is particularly pronounced when stainless steel is used as the material to constitute the band.
  • the remaining portions which are unaffected by the grinding action provide the required ductility so as to permit the band to be fitted onto the tooth of the patient.
  • the upper or occlusal edge of the thinned parts of the band is usually left in its original dimensions, so as to provide the orthodonist with a strong non-cutting edge to permit him to push the band down over the tooth without crumpling or bending the edge.
  • Other bands, such as anterior bands may have the thinned areas extending from edge to edge. Alternately, the thinned areas may be limited to the central parts of the band, as will be described.
  • the bands of the present invention having their interproximal portions thinned, are advantageous in United States Patent that there is less total space between the teeth to close after the bands have been removed. Moreover, the application of the bands of the invention is less painful since there is less initial separation of the teeth required. This latter factor often results in less work for the orthodontist since, in many instances, the initial tooth separation step may be eliminated. Also, the use of the bands of the invention results in fewer problems of tooth relapse and rotation, as well as in greater patient comfort.
  • FIG. 1 is a perspective view of a typical pre-formed molar band which may be treated in accordance with the concepts of the invention
  • FIG. 2 is a top view of the pre-formed molar band of FIG. 1;
  • FIG. 3 is a side view, partly in section, showing the band thinned across part of its interproximal portions in accordance with the concepts of the invention
  • FIG. 4 is a top view of a typical pre-formed anterior band treated in accordance with the concepts of the invention, with thinning in the interproximal portions extending from the lower edge to the upper edge of the band;
  • FIG. 5 is a side view of the band of FIG. 4, partly in section, and showing the band treated in accordance with the concepts of the invention with its interpoximal portions thinned;
  • FIG. 6 is a side View, partly in section, of an anterior band similar to the band of FIG. 5, but thinned in an area in the center of the proximal portions leaving the incisal and gingival edges of the band with their original thicknesses for maximum resistance to ciumpling.
  • the tooth band shown in FIGS. 1-3 is a pre-formed molar band.
  • the band is designated 10, for example, and, as shown, includes a distal side, a mesal side, a buccal side, and a lingual side.
  • the buccal side is to the outside and the lingual side is to the inside.
  • the distal and mesal sides constitute the interproximal portions of the band.
  • the tooth band also includes an upper edge, designated the occlusal edge, and a lower edge designated the gingival edge.
  • the mesal and distal sides are thinned by an abrading action.
  • the occlusal edge is not thinned, so as to provide a surface for the orthodontist to force the band down over the tooth and having sui'licient edge strength to resist crumpling or bending.
  • a grinding action such as described in the aforementioned copending application, produces a simultaneous hardening of the metal in the band in the affected areas, especially when a material such as stainless steel is used, so that there is no overall loss in strength of the band.
  • the ductility of the remainder of the band is sulicient so that the bands may be fitted onto the tooth, as easily as the prior art bands, and with the aforesaid advantages due to the thinning in the interproximal portions.
  • this thinning of the interproximal portions of the band are advantageous Abecause the fitting of the bands to the teeth of the patient is less painful and requires less work for the orthodontist. Also, the use of the lbands of the invention results in less total space between the teeth to close after the bands have been removed, and fewer problems of tooth relapse and tooth rotation.
  • the anterior tooth band shown in FIGS. 4 and 5 is designated '12, and, as shown, includes a distal side, a mesial side, a labial side and a lingual side.
  • the labial side is to the front and the lingual side is to the rear, and the distal and mesial sides form the interproximal portions of the band.
  • the tooth band of FIGS. 4 and 5 also includes an upper edge, designated the incisal edge and a lower edge designated the gingival edge.
  • the mesial and distal sides, that is the interproximal portions are thinned by an abrading or grinding action; with the thinning extending approximately one-third the entire width of the band from the incisal edge to the gingival edge, its center being positioned such as to provide the thinnest point at the interproximal contact.
  • the metal used in the band is one, such as stainless steel, which becomes work-hardened during the grinding action. Therefore, the grinding action which thins the band at the designated places simultaneously produces a hardening of the metal in the band in the affected areas. This assures that there is no overall loss in the strength of the band. Moreover, and as mentioned above, the ductility of the remainder of the band is suf ficient so that the band may be fitted onto the tooh, as easily as the prior art bands.
  • an anterior band is shown in a view similar to the view of FIG. 5, the latter band being designated 14.
  • the thinning action is limited to an area at the interproximal contact points of the band, leaving the incisal and gingival edges with their original thickness.
  • the band of FIG. 6 is particularly configured so as to exhibit sufiicient edge strength to resist bending of the sides of the band when it is moved into place down over the tooth of the patient.
  • An orthodontic tooth band for encircling a tooth formed of a ductile metallic material and having buccal, distal, lingual and mesial sides, and having occlusal and gingival edges, at least parts of the distal and mesial sides of said band being thinner than the lingual and buccal sides thereof.
  • An orthodontic band for encircling a tooth having a proximal portion, and configured so that at least part of said proximal portion of said band is thinner than the remaining portions thereof.
  • An orthodontic tooth band for encircling a tooth said band being formed of a ductile metallic material having buccal, distal, lingual and mesial sides, and having occlusal and gingival edges, in which the thickness of said occlusal edge of said band is essentially uniform around the periphery thereof and is substantially that of said buccal and lingual sides thereof, and parts of said distal and mesial sides of said band displaced down from said occlusal edge thereof being thinner than the lingual and buccal sides thereof.
  • An orthodontic band for encircling a tooth having a proximal portion, said band being configured so that at least a part of said proximal portion thereof is thinner than the remaining portion thereof, and in which said thinner proximal portion of said band has an increased thickness adjacent the upper edge of said band corresponding to the thickness of the remaining portions of said band.
