DE2744740C2 - Adjustment device for orthodontic adjustments with inner arch - Google Patents

Description

, The subject of claim 1 of the main patent is an adjustment device for orthodontic regulations marked with inner bend for setting connected tooth wraps or tooth sleeves by means of a clamping sleeve with a wedge-shaped longitudinal groove that can be pushed over at the inner end of the curve, which is the clamping sleeve with wedge expansion on the Dn. curved end shifting and can be clamped when relaxed.

It is now the task of the present development for this clamping device to open up a further possible application in the inner arch clinic. For this purpose, the aforementioned adjusting device is characterized in that on inner bends with guides tooth sleeves on both sides and associated regulating

spring bends such clamping sleeves are switched on as a stop to readjust the spring tension.

Furthermore, according to another thought, the

ίο Invention of the clamping device as a coupling or expansion piece for regulating bends and finally serve as adjusting hooks for drawstrings.

Embodiments of the invention are based on FIGS. 1 to 8 explained. It shows

F i g. 1 and 2 each show the plan view of inner arch arrangements with adjusting devices according to the invention.

F i g. 3 and 4 look at a particular detail about this,

F i g. 4 to 6 the top views of further inner arch arrangements,

7 the top view of a jaw expansion arrangement and

Fig. 8 the view of a particular detail For this.

In the drawing, FIG. 1 and 2, for example, show a top view of a dental arch 21 with an inner arch technique used in each case for setting up the front teeth in the direction A. For this purpose, in each case

jo an inner arch, ie an arch wire 22 held on both sides by means of guide tubes 23 on toothed belts 24. These archwires 22 are then assigned regulating spring arcs 25, which apply their spring pressure A to the front teeth and should be adjustable according to the treatment position, in order to simplify the cumbersome adjustment that was previously necessary. For this purpose, two clamping sleeves 26 of the type described above are provided between the guide tube 23 and the end 27 or 27a of the regulating spring arcs 25 in tandem for distance adjustment B and thus 'readjustment of the spring tension'.

While in the first embodiment of FIG. 1, the spring ends of the regulating spring bow 25 at * 27 around the arch wire 22 with clamping sleeve 26 as Stop are looped, are in the second embodiment according to F i g. 2 the spring ends of the regulating spring bow 25 received at 27a in plug-in tubes 28 on the clamping sleeves 26. Furthermore you can according to FIG. 3 the guides on the toothed sleeves 24 also as a clip 23a for laterally engaging and disengaging the ends of the archwires 22 can be formed, allowing installation and removal without removing the toothed belts much simplified.

Furthermore, in FIG. 4 again shows an inner arch arrangement 22 // for the dental arch 21, the a clamping sleeve 26 continue to serve as a stop on the guide tube 23 from the toothed belt 24, while the second clamping sleeves in elongated form as a coupling piece 29 for the regulating bend, an inner bend , 22 can be used to attach extension parts 30. The clamping sleeves can also be used as coupling pieces 29 for assembling inner bends 22a and 226 are used.

Furthermore, according to FIG. 5 with inner bend arrangement 22 // the clamping sleeves in elongated form as expansion pieces 31 for inner bends 22a, 22b with crossbars 32a, 326, which are placed on clamping sleeves 26 for displacement and are provided for expansion.

Air gap 33 are used, activation being achieved in the transverse direction. They can also Clamping lugs 26 according to Fig. 6 with Veistellhaken 34 in conjunction with elastic tension straps 35 to form stationary tooth hooks 36 for tooth regulation.

Finally, FIG. 7 nor the twisting of Clamping sleeves in connection with an expansion screw 37 for tensioning the jaw sutures (pallatinal split) when the seams are too narrow Jaw. The way a screw can travel is limited because it is a closely spaced jaw handeil and therefore no screw can be used, which has a «» extremely large elongation with correspondingly long screw is required. This pallatal split must also take place very quickly, i. H. within a Week to prevent them from growing together too early.

In the illustration according to FIG. 7, a transverse clasp is now aube 37 in conjunction with the stretchable slide consisting of four angled guide pins 38 secured by means of a clamping sleeve 26. Here are for Formation of the transverse clasp the four guide pins 33 inserted on the one hand at 39 on the expansion screw 37 and on the other hand connected to tooth sleeves 24 by means of angled portion 40 by means of clip guide 41. The clip guide 4J is for this purpose according to FIG. 8 as a one-sided plastic spring hook 42 for easy insertion and Disengagement of the transverse brace bracket 40 is formed. Thus, installation and removal becomes an activation adjustment and the replacement of longer expansion screws 37 is considerably simplified.
