  • the posterior bite blocks 165d and 165e may be formed to have a curved surface corresponding to the occlusal surface of the tooth, rather than having a flat upper surface. In this case, one surface of the tooth may be formed to surround (165d) or may be formed to extend to one side (165e).
  • the pre-byte byte block 160 and the pre-byte byte block 165 may be filled with a filler, or may be formed in an empty form.
  • the portion 161 where the bite block and the transparent brace meet may cover the tooth surface to establish a boundary between the tooth portion and the bite block, or the tooth receiving portion of the device and the internal space of the bite block may be connected without covering the tooth surface.
  • the anterior part byte block 160 and the posterior part byte block 165 may be integrally formed on the transparent calibration base 110, or may be separately manufactured and combined.
  • Figure 10 is an exemplary view showing a modification of the various transparent braces by the input of the auxiliary correction conditions according to the dental condition of the corrector.
  • the transparent braces 100 are formed to cover all of the pure surface l, the occlusal surface o and the lingual surface n of the tooth T, as shown in FIG.
  • the transparent braces 100b may be formed to extend in the form of covering the palate (palate) in the upper jaw, or may be formed in the form of covering the lingual in the lower jaw. That is, as shown in (b) of Figure 10 may be provided with an extended surface 170 extending from the lower portion of the lingual surface (n) of the tooth (T) toward the lingual side.
  • the transparent brace 100c exposes the pure surface l of the tooth T to the outside and only the occlusal surface o and the lingual surface n of the tooth T. It may be formed in a covering form. In this case, the extension surface 170 may be provided to reinforce the corrective force.
  • the anterior portion (front teeth) of the transparent calibrator 100 may be formed in a shape in which a pure surface l is drilled. That is, when viewed from the front, some teeth may be formed in a form in which only the canine and molar parts are wrapped without the transparent braces. As a result, some of the teeth are not accommodated in the transparent calibration base and are formed in a more aesthetic form exposed to the outside. At this time, the occlusal surface o can be removed together with the pure surface l.
  • Figure 12 is a form manufactured by adding only the aesthetic condition to the basic calibration conditions in the manufacture of the transparent calibrator.
  • various tattoos 180 may be attached to the pure surface of the transparent calibrator 100a, an image 181 may be painted, or a decorative member 183 such as cubic may be attached to add aesthetics.
  • the transparent braces 100a may be formed to be different from each other in the color of the tooth accommodation portion.
  • the transparent calibrator 100a may be used to reveal the personality of the corrector, or in some cases, may be used as a one-time use for use in a play or a movie.
  • the method for manufacturing a transparent calibrator according to the present invention and the transparent calibrator manufactured by the present invention assist in improving or improving aesthetics in addition to basic calibration conditions for applying orthodontic force based on the teeth data of the braces. Calibration conditions and aesthetic conditions are further considered and manufactured.
  • the present invention relates to a method for manufacturing a transparent brace, and may be applied to the dental field such as orthodontics and the industrial field for oral treatment.

Abstract

La présente invention concerne un procédé de fabrication d'aligneurs transparents qui comprend les étapes de : acquisition de données dentaires par balayage tridimensionnel des dents d'un utilisateur d'aligneur ; entrée, dans les données dentaires, de conditions d'alignement de base dans lesquelles l'alignement dentaire doit être effectué ; entrée, dans les données dentaires, de conditions esthétiques pour améliorer une sensation de beauté des dents ; et génération d'aligneurs transparents correspondant aux données dentaires dans lesquelles les conditions d'alignement de base et les conditions esthétiques sont reflétées, les conditions d'alignement de base comprenant des conditions de rotation, extrusion, intrusion et d'alignement d'axe de dent des dents, et les conditions esthétiques comprennent une couleur des dents de l'utilisateur, le fait que les dents de l'utilisateur ont été extraites ou non, l'état de dents cassées, les tailles des dents, et un rapport entre des dents voisines.
