Abstract

Anchoring apparatus for erecting palatinal displaced upper canines, characterized in that the apparatus consists of one or two loop bows (1) and a plastic button attached to the palate (5).

Description

The adjustment of a palatally displaced upper canine is a demanding task, for which a suitable apparatus is required.

In a patient, the right or left or both upper canine teeth may be displaced. First, the displaced canines must be exposed and a pull chain adhesively attached to the canine crown. After exposing and attaching the pull chain, the canine is moved by an appropriate force transmitted from an anchoring device to the pull chain attached to the canine crown.

The movement of the canine is initially palatinal to distal, to erect the canine around the center of rotation. After erection, the canine is transferred to the vestibular via the occlusion of the lower teeth.

For the power transmission suitable force application points are required on the anchoring device, on the one hand allow a train in the desired direction and on the other hand prevent the tilting or Mesialwandern the so-called anchoring teeth.

The planning and execution of the treatment is the task of the orthodontist. When orthodontic treatment should be taken to make the apparatus as simple as possible and the entire duration of treatment and especially the duration of a multi-band apparatus as short as possible.

1. a) Verankerung durch eine eingesetzte Multibandapparatur (Brackets mit Bogen), wobei ein hochdimensionierter slotfüllender Bogen durch die vestibulär liegenden Slots der Brackets genutzt wird. Der Kraftansatz ist von der Zugkette auf den eingesetzten Bogen bzw. auf ein Bracket gerichtet.
2. b) Verankerung transpalatinal durch eine gelötete Apparatur: Dafür werden konfektionierte Bänder rechts und links auf die oberen ersten Molaren gegebenenfalls auch auf die ersten Prämolaren gesetzt und diese Bänder intramaxillär-transpalatinal (über den Gaumen) und gegebenenfalls zusätzlich intramaxillär von Molar zu Prämolar miteinander verlötet. Zusätzlich wird ein Teilbogen angebracht, um die Kraft auf den freigelegten Eckzahn zu übertragen.
3. c) Verankerung durch am Gaumen gesetzte Miniimplantate: Die Miniimplantate werden durch einen zusätzlichen chirurgischen Eingriff in den Gaumen eingebracht. Auf diese Implantate wird eine Apparatur gefertigt, die die Kraft aufnimmt.

Anchoring devices for adjusting palatally displaced maxillary canines have been designed as follows:

1. a) Anchoring by a used multi-band apparatus (brackets with bow), whereby a high-dimensioned slot-filling arch is used by the vestibular slots of the brackets. The force approach is directed by the pull chain on the inserted bow or on a bracket.
2. b) Anchoring transpalately through a brazed device: For this purpose, prefabricated ligaments are placed on the upper first molars on the first premolars, and these ligaments are intramaxillarly-transpalatinal (via the palate) and optionally additionally intramaxillarly soldered together from molar to premolar. In addition, a partial arc is applied to transfer the force to the exposed canine.
3. c) Anchored by mini-implants placed on the palate: The mini-implants are inserted into the palate through an additional surgical procedure. On these implants, an apparatus is manufactured, which absorbs the force.

1. a) Bei einer Verankerung an der eingesetzten Multibandapparatur ist zunächst eine etwa 6-8 monatige Tragezeit der Multibandapparatur erforderlich um die Verankerung durch einen slotfüllenden Bogen zu erreichen. Erst nach dieser Zeit kann mit der Bewegung des Eckzahnes begonnen werden. Hierbei wird die gesamte Multibandtragezeit um die Zeit der Vorbereitung (6-8 Monate) und die Zeit der Einordnung des Eckzahnes, die im Durchschnitt 6-12 Monate beträgt, also insgesamt um durchschnittlich 12-18 Monate verlängert.
2. b) Mit einer transpalatinalen Verankerung, wie sie bisher beschrieben ist, müssen die eingesetzten Teilbögen gewechselt werden, um den Kraftangriffspunkt variieren zu können. Eine ausreichende Abstützung gegen Kippen und Mesialwandern der Verankerungszähne ist nur begrenzt vorhanden.
3. c) Eine Verankerung durch am Gaumen gesetzte Miniimplantate erfordert einen zusätzlichen chirurgischen Eingriff zum Einbringen und einen weiteren chirurgischen Eingriff zum Entfernen der Implantate. Eine Einheilphase muss abgewartet werden. In seltenen Fällen gehen die Implantate verloren. Die Implantatverankerung gibt zwar einen guten Schutz gegen Mesialkippung und Wanderung der Seitenzähne, die Behandlung wird aber durch die Einheilzeiten verlängert und zusätzliche chirurgische Eingriffe sind erforderlich. Der Kraftangriffspunkt ist nicht vorgegeben. Durch eine Laborarbeit muss eine Apparatur für die Kraftaufnahme erstellt werden und diese bei Bedarf erneuert werden.

The apparatuses described so far have the following disadvantages:

1. a) When anchoring to the multi-band apparatus used, an approximately 6-8 month wearing time of the multi-band apparatus is initially required in order to achieve anchorage through a slot-filling arch. Only after this time can the movement of the canine be started. In this case, the total multibandage time is increased by the time of preparation (6-8 months) and the time of the cuspidation, which is on average 6-12 months, ie an average of 12-18 months.
2. b) With a transpalatal anchorage, as described so far, the inserted partial arches must be changed in order to vary the force application point. Sufficient support against tilting and Mesialwandern the anchoring teeth is limited.
3. c) An implantation of mini-implants placed on the palate requires an additional surgical procedure for insertion and a further surgical procedure for removing the implants. A healing phase must be awaited. In rare cases, the implants are lost. Although the implant anchor provides good protection against mesial tilting and posterior migration, treatment is prolonged by healing times and additional surgical procedures are required. The force application point is not specified. Laboratory work requires the creation of force-sensing equipment and renewal if necessary.

In the three methods described above, it is often necessary that after the canine is erected palatally for the movement of the tooth to vestibularly via the occlusion to the lower teeth, a bite block must be applied by attaching bites. Often, additional elastic bands have to be inserted between the upper and lower teeth.

An embodiment of the invention will be described with reference to 1 to 3 explained. Show it:

• 1 : The anchoring device for setting palatally displaced upper canines in occlusal view
• 2 : The anchoring device for the adjustment of palatally displaced upper canines from vestibular
• 3 The anchoring device for setting palatally displaced upper canines in oblique palatal view

The claims 1-4 describe by which innovative elements this apparatus allows an erection and transfer of palatal displaced canines.

In protection claim 1 it is shown that the apparatus contains both a device for applying the force, as well as the anchoring against mesial forces.

The protection specified in claim 2 and Schutzanpruch 3 invention is based on the problem to provide an apparatus that allows both the erection of the palatally displaced canine to the distal, as well as the transfer of the canine tip after vestibular. The apparatus contains a loop bow ( 1 , (1)), which runs from palatal to vestibular. Due to the location of the loops palatinal ( 1 , (2) and 3 (2)), the palatal force application to erect the canine is possible. Once the canine tip is centered between the lateral incisor and the first premolar, the force applied to the rendition loop ( 1 (3) and 2 (3)), which lies vestibularly slightly apical to the gingival course between the lateral incisor and the first premolar.

Since, as explained in protection claim 3, the rendition loop ( 1 (3) and 2 (3)) and so that the force application for the transfer of the canine tip apical Ginigvaverlaufes occurs, there is no collision of the canine tip to the opposing teeth of the lower jaw, therefore, for the transfer of the canine to vestibular no Bisssperrung by additional bites or intermaxillary elastics required.

The vestibular loops are attached at the level of the first and second premolars ( 1 (4) and 2 (4)) and facilitate a force application, which may be necessary in the further course of the canine setting, towards vestibular-dorsal.

In canine erection and adjustment, maximum anchoring against tilting and mesial migration of the anchoring teeth is required. This problem is caused by the plastic button ( 1 (5) and 3 (5)), as described in protection claim 4 is solved. Force application from the canine to the anchoring apparatus for setting palatally displaced maxillary canines places forces on the molars, which are mesially directed and induce mesial tilting or migration. These forces are controlled by the plastic button ( 1 (5) and 3 (5)), which rests on the palate and neutralized. The recess on the plastic button ( 1 (6) and 3 (6)) in the area of the displaced canine allows unimpeded movement of the canine.

The protection described in claim 2 and protection claim 3 loop arc ( 1 (1)) can be used both for the right and mirrored for the left upper row of teeth, so shifted in the right right upper canine right loop loop, relocated left upper canine left of the loop bow and in both right and left shifted upper canines are attached to the right and left loop bows.
