Definitions

  • the present invention relates generally to devices for cleaning orthodontic brackets.
  • the present invention is directed to an apparatus for removing adhesive residues from the surface of brackets, palatal buttons and orthodontic tubes used.
  • brackets At the beginning of the orthodontics, the procedure used for the placement of brackets consisted of welding brackets to a band that was cemented around the tooth. With the passage of time and the development of adhesives for dental use, it was possible to eliminate this band to directly cement the brackets to the teeth. These adhesives have a high adherent force that allows them to work well in the adhesive-enamel and adhesive-bracket joint. The common failures in said adhesives are related to the contamination of the surfaces where the adhesive is applied, bad manipulation of the brackets or lack of contact area of the joint. In order to keep the brackets in position for a longer time, a wire mesh was placed on the brackets to increase the contact area in the adhesive-bracket joint and create an improved mechanical retention.
  • the cemented brackets still have failures in the adherent force and consequently detach.
  • a bracket detaches from its bracket - adhesive - enamel joint, it causes a delay in orthodontic treatment as is known by those skilled in the art.
  • the dentist has two options to solve this * problem: i) replace the detached bracket with a new one, but this raises the cost of treatment; or ii) try to recover the detached bracket by removing in all the adhesive residues that are still adhered to the bracket in order to be able to place it again.
  • Bracket cleaning Although this form of cleaning is the most viable because it does not degrade the hardness of the metal, does not reduce the contact area and allows the elimination of adhesive residues between the wire mesh, it still has some drawbacks.
  • the bracket with adhesive residue is inserted into a cleaning booth with sandblasting where a pressure sand bath is applied directly on the surface of! bracket that presents adhesive residue.
  • a pressure sand bath is applied directly on the surface of! bracket that presents adhesive residue.
  • due to the dimensions of the bracket it is very difficult to manipulate it inside the cabin, regardless that the vision that can be had inside the cabin is very limited. Consequently, it is not possible to obtain a control of the sandblasting and therefore the sand in addition to removing the remains of adhesive, strikes the vestibular face of the bracket that produces a rough surface.
  • a rough surface on the vestibular face of the bracket translates into an increase in the frictional force that prevents the sliding of the bracket on the wire, which results in less movement of the tooth to which this cleaned bracket is placed compared to the rest of the teeth prolonging the treatment in this way.
  • the principle of cleaning or treatment with sandblasting or sandblast consists in mixing particles or abrasive bodies (for example, sand) with a flow of gas or air, which will accelerate these particles by impacting them against a surface, causing erosion or abrasion. on the impacted surface.
  • This principle has been widely used in the industry in general such as, for example, for surface cleaning, coating of materials, providing finishes, cutting of materials, etc.
  • any of the devices described in the previous patents would be useful for removing adhesive residues and cleaning a bracket.
  • One of the disadvantages that these devices have is the difficulty in holding and retaining a bracket contaminated with adhesive in position since it is so small that it is difficult to manipulate and it is likely that the abrasive attack the vestibular surface of the bracket, eliminating the polished finish that You must have this face.
  • a second drawback is that none of these devices have a container or reservoir to collect the abrasive already used.
  • the mixture of abrasive with gas leaves the nozzle of the device, then hits the bracket and the abrasive bounces, but since there is no container or deposit that receives the abrasive used, it will be dispersed in the environment.
  • the abrasive dispersed in the environment implies that, on the one hand, both the dentist and the patient will be breathing this abrasive and, on the other hand, the abrasive will be deposited on all surfaces of the office or work area.

  • These devices do not have the disadvantage of spreading the abrasive towards the environment since all the abrasive is confined inside the cabinet.
  • this class of devices still has the disadvantage of not properly manipulating the bracket during cleaning and, in this case, its handling has a greater difficulty because the cabinets have two holes through which the operator inserts the hands, which subtract mobility.
  • these cabins have a window or peephole where you can see inside the cabinet but being made of glass or some transparent non-impact resistant plastic is easily scratched by the action of the abrasive, which makes vision difficult by raising the risk of attacking the vestibular bracket face in such a way that it is very difficult to clean a bracket in these devices.
