Definitions

  • This utility model refers to a bracket positioning instrument, which belongs to the technical field of orthodontics.
  • Orthodontics is a branch of dentistry that studies and corrects irregularities and abnormalities in the position of teeth and jaws.
  • Orthodontic treatments use braces, which are devices that can be cemented to the vestibular surface of the tooth, which is the surface in relation to the lips and cheeks.
  • An archwire is also used, which is the element that joins the braces together and generates the force to mobilize the teeth.
  • brackets There are two types of brackets depending on the way the arch is attached to them, and they are:
  • Self-ligating ones are similar to the previous ones, they have a horizontal slot, but they do not have the vertical slot, instead they contain a cover mechanism to fix the arch on them.
  • Both conventional and self-ligating brackets are normally placed halfway between the mesio-distal distance of the tooth, which is the distance from the point of contact with a neighboring tooth to the point of contact with its other tooth. neighbor. They must also be positioned with an appropriate inclination, since the ideal is that their horizontal slot is perpendicular to the long axis of the tooth. For this reason, it is important to have a visual reference of said axis and of the vestibular surface.
  • the occlusal plane is an imaginary line that passes through the cutting and chewing edges of the teeth of the same jaw.
  • brackets can cause complications during the treatment phases, affecting the leveling of the teeth and leaving some pieces higher than others, and also affecting their alignment, causing some to be rotated. Therefore, precision in the placement of the bracket is one of the most important pillars of the treatment to avoid unwanted movements; and on the other hand, to avoid using clinical time to correct its position after cementation.
  • the positioning portion of the tooth section (155) is only contained on one side of the instrument to place it on the edge of the tooth, and does not extend to the other side, so it does not provide a reference of the occlusal plane.
  • Patent EP4046588 describes an instrument that resembles one of the most commonly used instruments today, and like most positioners, it was only designed to position the bracket according to the height needed; and it has the drawback that when removing it from the bracket, it can be displaced, so its placement must be checked repeatedly and its location constantly modified.
  • both this instrument and the others mentioned do not facilitate the visualization of all the anatomical references that influence the correct position of the bracket, such as: the mesio-distal distance of the tooth, the occlusal plane, and the long axis of the tooth.
  • the solution must be a manual dental instrument that helps to visualize all the anatomical references that determine the adequate position of the bracket on the vestibular surface of the tooth.
  • the present utility model was developed, which consists of an instrument comprised of a gripping body, and at one or both ends it has a neck, which contains a working tip.
  • the working tip has a positioning plate to be inserted into the horizontal slot of the bracket; a support plate that is placed on the edge of the tooth and facilitates the visualization of the occlusal plane when it is aligned with it, so that the bracket is not positioned higher or lower than the required height; and it also has a rod that helps to visualize the long axis of the tooth when it is aligned with it, which allows the horizontal slot of the bracket to be placed perpendicular to said axis, and to position it at an appropriate inclination.
  • the instrument of the invention allows for a good view of the vestibular surface of the tooth while it is being used, which facilitates the placement of the bracket in the mesio-distal distance; it can be positioned without the need to repeatedly check its position, and the cement can be photocured while it is being held, thus eliminating its displacement when the instrument is removed.
  • the working tip has a connecting end that is contained in the connecting end of the neck, and is contained by one or more retaining mechanisms. Such ends may not be permanently attached, therefore, the working tip can be interchanged, it can be chosen according to the height at which the bracket is to be positioned and adjusted within the neck in the most convenient position, which provides versatility to the instrument of the invention compared to other positioners.

  • Fig. 2 is the structural representation of the working tip of the utility model, in a sagittal view.
  • Fig. 3 is the structural representation of the working tip of the utility model, in an oblique view.

  • Fig. 7 is a front view of an application example, showing the working tip contained in the neck and positioning the bracket on the tooth. A portion of the gripping body is also shown.
  • This utility model is an orthodontic bracket positioning instrument.
  • the benefits and advantages over current instruments have been shown and described above; and its features and the way it works are described in more detail below.
  • the bracket positioning instrument comprises a gripping body (1), and at one or both ends it has a neck (2) which has a connecting end (3).
  • the gripping body (1) is elongated so that it can be held by the operator's hand, and is smooth or provided with a non-slip pattern.
  • the neck (2) is straight, curved, has an angle between 80° and 170° in relation to the major axis of the gripping body (1), or has two angles on the same plane, one between 20° and 90° in relation to the major axis of the gripping body (1) and then another between 80° and 120° in relation to the first angle; and in its final extension or after its last angle, it has the connection end (3) which is solid or hollow, and has a shape complementary to the shape of the joining end (5) to allow a precise and stable coupling.

These distances are between 2 mm. and 9 mm., and provide the different heights at which the bracket can be placed on each tooth. To position the self-ligating brackets, the operator can use the working tips (4) whose distances are between 6 mm.
  • the support plate (6) can be made to coincide with the occlusal plane as if it were a continuation of it, and as it protrudes from the vestibular surface of the tooth, the operator will be able to have the reference of said plane to achieve an adequate position in relation to the height.

Abstract

L'invention concerne un instrument de positionnement de brackets, appartenant au domaine technique de l'orthodontie. Les instruments actuels ne facilitent pas la visualisation de toutes les références anatomiques qui déterminent le bon positionnement du bracket sur la dent. L'instrument selon l'invention apporte une solution à ce problème du fait qu'il est composé d'un corps de prise et possède, à une ou deux extrémités, un col contenant une pointe de travail. La pointe de travail est composée des éléments suivants : une lame de position destinée à être introduite dans la rainure horizontale du bracket ; une lame d'appui qui se place sur le bord de la dent et facilite la visualisation du plan d'occlusion lorsqu'on fait coïncider la lame avec celui-ci ; et une tige permettant de visualiser l'axe de la dent lorsque l'on fait coïncider la tige sur celui-ci. De plus, ledit instrument offre une bonne vue de la face vestibulaire lorsqu'il est utilisé ; et les pointes peuvent être interchangeables.
