Hoppelplatte-for orthodontics

The renewal relates to a "double plate for the treatment of 'bite anomalies in orthodontics and has the task ^ an uncomplicated movable connection between the upper and lower jaw plates for the-soJaaffen _? _ Di © to achieve the lowest possible volume of the plates, allows on * d Difficulties in manufacture and use largely termedeto

The desire to reshape the: dental arches and faster and reliable correction of the bite position means that the double plate can be used by children and adults without difficulty can be worn all day * without this Appearance and language of the patient are disturbed more than is absolutely necessary »

Accordingly, it is now proposed according to the invention that angled metal spurs to be attached to one or both sides of the upper plate are provided as guiding lines between the upper and lower plates _? the slanted flaps on the lingual side that are carved out of the material of the lower plate slide. Reduction of the need for piatz and the possibility to readjust the lead .. * _

At the same time, "it has still proven to be two-fold, if the guide elements (spurs and inclined surfaces) in the tooth =? arc direction preferably approximately between the last premblaren and the first molar are arranged «, in this way will namely, tipping of the plates is best avoided and the tongue is best given space

In precision it has also been shown to be advisable if the spurs, when arranged on both sides, are approximately parallel, possibly slightly converging towards the lower jaw, attached to the upper plate *

While the double-disk itself largely industrial prefabrication withdraws because they are adapted to the best possible individual case the need has © s but als'sehr proved conducive to their production if correspondingly shaped Pührungssporn © made available .kSnnenO Pur. this will continue to do so in that the guide knuckle has an approximately oval cross-section. On this quietly - can ' - your guide arm be given the smallest «possible» width with maximum strength · ■.

Furthermore, it is advantageous if the Be'festigungasohenkel "Vor--, recesses _or the like od _e .yerankerungsmlttel for fixing in the material of the upper plate has to reach ma ^ that the acting forces, nieht -to destruction of the plate. Lead könneno

From Abbo 4 it can be seen - that - to remedy - the anomalies described, the plates are approximately symmetrical ,

- the spurs 1 being approximately parallel or "slightly" aum - lower jaw " converging-are to be assigned ”. You also see from this, that the spurs are arranged as widely as possible should be ^ in order not to "unnecessarily narrow" the tongue, - ".".

If only a pure lateral guidance of the lower jaw is intended, a double plate with a spur on that side can be used, after which the displacement should take place. ': · -.

It hardly needs to be mentioned that auxiliary elements (springs, screws, etc.) can be used in the same way as with individual panels _? and that the spurs also have to be added subsequently to already finished plastic panels

Double plates of this type have also proven themselves well in difficult cases ^ like Z ₀ Bo in older working people, in crippled teeth with collapse of the support zone and distal occlusion of more than a premolar width, as well as in progeny in the development stage ₀ In this case, the additional The use of a chin cap with vertical bars and elastic bands to the upper plate is recommended _o But also in other cases, for example after operations or jaw fractures, the use of the new double plate can be advantageous
