Definitions

  • the invention relates to a connection device between a dental appliance, such as an expander, and its anchorage to dental pieces, usually to molars or premolars.
  • This device comprises a connector which in turn comprises an appropriate channel to accommodate in the interior thereof the clamping wire or branch of the dental appliance.
  • This wire which we refer to as branch, will act as the axis on which the connector and therefore the anchorage to the dental pieces will pivot.
  • this connector allows the articulated connection between the expanders, normally a fixed jack type, and the anchorage elements thereof in dental braces.
  • This invention falls within the dental sector, more specifically in the field of orthodontics.
  • the expansion force is usually applied by means of a fixed jack mechanism anchored to some upper teeth (usually molars and premolars) by means of braces to which the fixed jack mechanism is welded.
  • braces fully encircle the teeth they are fixed to.
  • the Minn expander which includes a spring to soften the application of the force.
  • This type of appliance is also used in the lower jaw to cause expansion.
  • the connection between the jack system (Hyrax, Haas ) and the teeth has commonly been carried out through metal braces to which the appliance is welded by silver or laser welding, silver welding being the most common type.
  • This welded anchorage system also generates other problems and thus, for example, damages the braces because they become weakened through heating and this makes it easier for them to break again.
  • a system is preferred in which it is not necessary to heat and therefore cause the loss of properties of the expander or the anchorage braces, and in which an additional metal such as silver need not be applied.
  • the present invention focuses on providing a solution to all these adverse aspects of the current art.
  • This lingual cleat system does not allow the free rotation of the wire inside the band and in order to insert the wire into the lingual cleat, the wire needs to be bent over itself, which often causes breakage.
  • Patent US2002106604 discloses a connection element between an orthodontic appliance and the dental pieces, this element consisting of a laminar-shaped surface that binds to the tooth and whose opposite part presents a retaining element of the appliance with a channel in its interior and a protrusion, but in no case presents a pivoting connection to an anchorage.
  • patent US2013034822 refers to a device for the connection of an orthodontic appliance to a dental piece, said device being a laminar-shaped piece whose anchorage element is a protrusion on its outer side, also without the characteristic pivotal movement.
  • Fitting and adjustment thereof are facilitated without a need to oversize the anchorage braces and thus avoiding the need for fillers.
  • the position of the anchorage brace adjusts to the position of the dental pieces in the event of a change in their inclination, avoiding dysfunctions or unwanted effects.
  • the invention relates to a connection device between a dental appliance such as an expander and its brace for anchorage to the dental pieces, this connection being mobile and, in particular, having a pivoting movement allowing a hinge like movement of the anchorage brace relative to the branch.
  • the invention refers to a connection device between the dental appliance and its pivoting anchorage which comprises: Means for clamping onto and retaining the branch.
  • the means for attachment to the anchorage brace comprise a suitable base to be attached to the braces. This base is connected to the braces by any means that allow permanent connection thereof.
  • the means for clamping onto and retaining the branch comprise:
  • a mooring element such as a through hole or a protrusion such as a sphere.
  • the latter In order to prevent the branch from coming out of the main channel, the latter has at least one narrowing area where its mouth has an opening smaller than the diameter of the lodged branch avoiding the accidental exit thereof, or an area of full closure of the channel.
  • the device may comprise a groove in its support that runs parallel to the main channel and facilitates the entry and exit of the branch in and out of this channel.
  • the end of the narrowing area may present a preferably rounded profile.
  • the device may optionally comprise mooring elements.
  • the possible mooring elements include protrusions, notches or holes on the outer wall of the main channel.
  • the device which is the object of the present invention in addition to serving for skeletal expansion, may also collaborate in the traction of the dental pieces and to this end a secondary channel is provided, on the outer side of the wall of the main channel, which runs in parallel thereto and is suitable to accommodate the elastic elements that cause the traction.
  • a through tunnel is provided at the connection between the main channel and the support.
  • the repair can be performed on the spot at the dentist's clinic by replacing the broken brace with another one of the same number with the built-in connection device, thus avoiding recurrence and more appointments with the patient.

  • the same device allows its use as an element for dental traction.
  • Another of the advantages of the device described is that since it is a device that allows rotation on an axis, it also allows control of the molar torque during all phases of the treatment.
  • a device such as the one described allows easy housing in the patient's mouth by facilitating the adjustment of the braces (4) to the dental pieces and, on the other hand, in case of breakage or if for any other reason it is necessary to replace any part of the dental appliance, separating the braces from the rest of the appliance is carried out by simply removing the branch (2) from the main channel (8).

Abstract

L'invention concerne un dispositif de raccordement entre un appareil dentaire, tel qu'un extenseur, et son ancrage sur les pièces dentaires, habituellement sur des molaires ou des prémolaires. Ce dispositif comprend un raccord (5) qui, à son tour, comprend un canal principal approprié (8) pour recevoir à l'intérieur le fil ou la branche de serrage (2) de l'appareil dentaire, de sorte que ce fil, que nous désignons branche (2), agit comme l'axe sur lequel le connecteur et par conséquent l'attache pour l'ancrage sur les pièces dentaires pivote, permettant la liaison articulée entre les extenseurs, habituellement un type de vérin fixe, et ses attaches d'ancrage dans des appareils dentaires.
