The teeth will be molded with a solidifying material. Through this impression, gypsum models can then be produced.

Diagnostic initial materials

We take the necessary photos, x-rays and impressions before the beginning of treatment in order to plan a therapy and to apply to the health insurance company.

ASR / Stripping

If teeth are very close or overlapping, it can be helpful to polish the surface of the tooth at the point of contact with the neighboring teeth to make it easier the movement of the teeth. In individual cases, by repeating this procedure several times, more space can be created for the teeth.

Bands / Rings

Bands are 0.1mm thick metal rings with elements for holding an arch wire.

Banding of the fixed braces

The fixed braces will be inserted. For this, the surface of the teeth is cleaned, pretreated and then the brackets are individually glued on. Individually adapted bands are glued to the molars. The last step is to use an arch wire that ties the brackets and the bands.

Arch wire

Wire settled along brackets and bands. It is available in different metals, cross sections, shapes and dimensions.


Brackets are part of a fixed brace appliance. They are glued to the teeth after preparing the tooth surface and are used to tie the arch. Brackets can be made of metal or ceramic.

Teeth Sealing

The greatest risk of damaging the teeth during the treatment with fixed braces is in the small surface surrounding the brackets. You can prevent the risk of damaging the enamel by sealing this area with a special sealing lack, whose protective effect lasts for up to one year.

Fixed braces

Consists of arches, brackets, bands and ligatures. The teeth are covered with brackets that are only removed at the end of the treatment, therefore the term “fixed”.


Abbreviation for cephalometric imaging. It is an X-ray of the entire cranium, which provides diagnostic information about the maturation model and the position of the jaws in relation to each other.


Abbreviation for rapid maxillary expansion appliance. This appliance is used to expand the upper jaw and consists of a special screw that is attached to the teeth using four bands.


is also called wrist root x-ray (HWA). This x-ray image is used to determine the skeletal age and therefore provides information about the expected growth.

Removable appliance

This device consists of plastic and various active elements. The patient can wear and remove it himself, which means that the success of the treatment depends heavily on the patient’s cooperation.


Thin, partially stranded wires will be fixed to the inside surface of the front teeth with special cement, in order to stabilize the treatment result.


Ligatures can be made of wire or highly elastic, synthetic material. They are used to fix the arch in the brackets.


Plaster models are duplicates of the individual jaw and tooth position. They are indispensable for orthodontic diagnostics and therapy. Models are important for diagnosis, documentation, treatment, appliance planning and appliance manufacture.

Panoramic X-ray (OPG)

It is used to determine the number of teeth, the location, mineralization, shape and size of the tooth germs as well as of the roots.

Removable retention appliance

Removable appliances without active elements to stabilize the treatment result.


A relapse means a reversion in the direction of the original tooth position after completion of an orthodontic treatment.

Separating/ sep. appointment

Before adapting the bands on the molars, it is necessary to create a little space between the molars. For this purpose, a small rubber ring is clamped into the interdental space 2-4 days before cementing the bands, moving in this way the teeth very slightly apart.
