  • Dental flanges or brackets are small pieces of dental fixation, used in orthodontics for the correct alignment of the dental pieces; they are metallic, ceramic or polymeric elements, which are welded to bands or glued directly on the surface of the tooth, serve to support the active corrective element, which is the arch.

  • the so-called active bracket has a clip or tongue with spring, which enters into the groove, which contains the orthodontic arch, allowing the round and smooth arches to work freely until the alignment and leveling phase is completed. Once this phase is finished, the clip begins to work on all the arches increasing its size according to the wire, which allows the arc to settle on the base of the groove, allowing it to transmit all the programming and response to the bracket.

  • These brackets are provided with fins that serve to engage a circular rubber band, or any elastic polymeric ring that fix the arch inside the slot of the bracket.
  • brackets known so far have the disadvantage of being very rigid due to the large contact areas between the bracket and the arc, generating contact areas between them that do not allow for a sufficiently fast and safe movement as if the bracket has it of our invention.

  • the great technical problem that the self-ligating technology imposes on us is basically the impossibility of its massive application due to the high costs, the difficulty of manufacturing, since it requires very expensive and advanced technology, and the size of the brackets as such increases with respect to that of conventional brackets, which generates additional discomfort to the patient by having them in the mouth and the difficulty for handling by the orthodontist, since the complexity of the existing self-ligating brackets is such that they require special training because part of the orthodontist.
  • This difficulty lends itself to several negative situations, namely: a) so that they are poorly positioned in the teeth, which can generate an unwanted movement b) for difficulties in clinical management at the time of opening and closing the bracket, which can cause very easily a permanent damage of the bracket Io that forces its automatic change, with the consequent monetary and biological costs; c) additionally, in the effort to open or close these brackets erroneously there may be the possibility of slipping instruments and lacerating patient tissues; d) oblige the orthodontist to change their traditional prescriptions or their traditional devices, for which they have been trained, with the consequent difficulties they may face; e) they require an expensive specific and indispensable instrument for its handling; f) the levels of force necessary for opening and closing the existing self-ligating brackets generate additional stress to the patient in addition to excessive force on the tooth with its corresponding biological cost.

Abstract

L'invention concerne un verrou à autoverrouillage comprenant une pince à autoverrouillage se présentant sous forme de structure ouverte, et formé de deux segments horizontaux postérieurs venant en contact avec les orifices et de deux segments verticaux. Dans la partie centrale des segments verticaux est formée une paire de boucles, c'est-à-dire une dans chaque segment vertical. Le segment horizontal complète la structure de la pince. Vers la partie centrale dudit segment se trouve un élément de préhension pouvant présenter une forme semi-circonférentielle. La pince à autoverrouillage et à faible friction est utilisée pour corriger un mauvais positionnement des dents.
