Birthday Computer Sayings

autumn hinge variants: Jasper Jumper, felx Developer, spacers, SUS, mini scope

The Herbst appliance: A brilliant idea
The Herbst appliance is usually named after its inventor Emil either fall or autumn autumn hinge apparatus. But there are also other names, such as Jasper Jumper, Flex Developer, or spacer (so called the orthodontic practice in Bad Saulgau their version of the autumn hinge). Google search tip: Since the autumn hinge more popular in the U.S. than here, we will find with the English Google search more info. 'Cantilever autumn ' Autumn Appliance ',' Autumn telescoping tube ' or' Hank telescoping tube ': keywords.

Modern autumn hinge
The basic idea of Emil autumn of 1934 is simple and ingenious: With small staffs, the back teeth connected above and below, so that you can not bite down completely and the forces of the mandible are diverted horizontally. Thus, the back teeth are pushed up to the rear and at the same time brought the lower jaw forward. Among adolescents in the growth phase, the autumn hinge also promotes growth in length of the mandible.

tinnitus and temporomandibular joint sounds
Since a reverse shift of the lower jaw not only an aesthetic Problem but also the cause of TMJ sounds (Kaugeräusche), temporomandibular joint pain and tinnitus may be helps the Herbst appliance here.

Late rediscovery in Germany
In Germany, the Herbst appliance only in the late 1970s by H. Pancherz (Uni Giessen) rediscovered. Pancherz failed to show 1997 as the first in many studies that the Herbst appliance promotes bone growth, sparking a surge. Since the 1980 fall of the hinge in Germany in combination with Bracktes is used more often. Almost all orthodontists in Germany (99%) know the Herbst appliance and a third uses it regularly.

( But beware: My orthodontist from Bad Saulgau who have for years specialized in the autumn hinge say that it can happen again and again that patients come to them, somewhere have a Herbst appliance can be installed, which then but always fall out or even worse, by the orthodontist, who has built, could not be removed again -. due to lack of experience )

The telescopic rods
telescopic rod
of three parts
Since the invention of the Herbst appliance by Emil Herbst is an attempt to optimize the apparatus, which allows different variants have been created. A special importance is the telescopic rods and their attachment to the teeth. The telescoping poles are therefore important because they absorb the entire force and redirect. You may not bend, not break and do not block it (like me happened once). They also need to work even in extreme situations, eg when tremor.

existed at the beginning of the bars for two main parts (tube and rod) which were inserted into each other. The disadvantage of this design is that the assembled rods disintegrate in the mouth can, for example, when the mouth is open too far (and in my case happened ). A more modern design was invented by an American, Stephen Hank: He built the telescopic rods from three pods fall apart and can not be open yet far (eg, Hank's Mini Scope telescopic rods from American Orthodontics). Other built a compression spring in the sleeves to make effect more permanent force to the teeth.

Scope Mini-bar
The telescopic rods (English telescoping tube autumn cantilver order) are usually screwed to the fixture attached to the tooth. It is important that the lateral movement of the mandible is not restricted. This is assured either by special screws with long necks or screw with a ball joint. The figure shows the lateral movement of the telescopic rod mini scope. to fix

The holding device on the tooth
To the telescopic rods to the back teeth, teeth with different holding devices are provided. Crowns are common, where there are small threads for the screws of the telescopic rods. But sometimes, the telescopic rods also attached directly to brackets or it is used a metal mold. Rare, but also possible to implant mounting screws. stabilize

for the crown with one another and to use the forces in accordance with the objectives, the holding devices are often connected to each other or with metal rods and sheets.

Depending on telescopic poles, fastening and holding devices are designed to be committed to the goals of the autumn hinge: Move
  • molars back
  • lower jaw forward to get
  • length spur growth

variants of the autumn hinge - Quick Reference

The original: Herbst appliance
is today mainly produced by the company Dentaurum (oldest dental company in the world). Dentaurum holds the rights to the brand name 'Autumn'. As described above, the crowned molar teeth are connected by small telescopic poles. The rods may be attached to brackets or other holding devices.

Herbst appliance from Bad Saulgau: Spacer
The spacer is a patented version of the autumn hinge, in which the crowns are connected to each other movable and additional metal sheets to ensure that the teeth move controlled. The spacer was developed by the orthodontic practice in Bath and came Saulgau with me for 12 months used. Here I have described the patented spacer variant detail ...

Jasper Jumper
springs: Jasper Jumper
The telescopic bars of the hinge will fall by springs (see something like this, as in ball point pens) replaced. The springs are often coated with plastic to protect the springs. Manufacturer: American Orthodontics.

rubber bars: felx Developer
were here replaced the bars of the autumn by small rubber hinge rods (Polamid) that bend like a spring and in this way can a lasting effect.

spring telescopic poles: SUS
Dentaurum next to the Herbst appliance also offers the Sabbagh Universal Spring (SUS) to. This telescopic rods are used where small springs are installed.

My experience with the Herbst appliance
twelve months I have worn the Herbst appliance (or the spacer-variant Bad Saulgau. About my experience with the Herbst appliance / spacer I have written extensively in this blog are. All reports about . the right navigation callable Here is a selection:
