BioBiteCorrector® with Multibracketappliance
The BioBiteCorrector versions MS and SP with a screw connector can be easily attached to multibracket wire. This orthodontic combination is used for treatment of Angle Class II Malocclusion.
The BioBiteCorrector MS as a passive-rigid appliance is able to precisely guide the mandible into bilateral Class I occlusion and therefore does not need coil springs.
The BioBiteCorrector SP supports the advancement of the lower jaw with an internal coil spring.
BioBiteCorrector versions MS (without compression spring) and SP (with compression spring) have a screw connector. These versions can be screwed to a square wire.
BioBiteCorrector MS and SP versions are always placed interproximally due to their screw connectors. The screw connector is placed between the canine and the 1st premolar in the lower jaw, and between the 1st molar and the 2nd premolar in the upper jaw.
The BioBiteCorrector® SP supports the advancement of the lower jaw with an internal coil spring. The BBC MS works based on the functional principles of the Herbst-appliance and therefore does not have an internal coil spring.
For the placement of a BioBiteCorrector, there have to be multibracket appliances in the upper and lower jaws, with steel archwires with a minimum size of 0.017″ x 0.025″.
In the lower jaw the steel archwire must have a cinch back distally from the first or second molar.
Tip: For the cinch back we recommend a Twister -Instrument. It helps to bend the arch very easily by 90° without risking removing the bracket from the tooth.
“Standard” is used in non-extraction cases.
Only in extraction cases in the upper jaw, ” Small” is used.
The BBC is supplied completely pre-assembled. Different appliances are available for the left and right sides. The BBC is fixed in place first in the upper jaw and then in the lower jaw.
The upper jaw connecting element is fixed in place between the first molar and the second premolar. The connecting element should not contact the bracket of the first molar. The screwdriver must be secured with dental floss to avoid aspiration or swallowing.
Slide the body on the archwire from the lateral side and then fix the screw.
After fixing in place the upper jaw connecting element, the lower jaw con-necting element is fixed in place between the canine and the first premolar. Slide the body on the archwire and then fix the screw. The connecting ele-ment should be situated as distally as possible and touch the mesial side of the bracket of the first premolar. However, the connecting element must not contact the canine bracket at all. Fix the other side in the same way.
After both sides are fixed in place, the lower jaw is guided back as far as pos-sible. If there still is distal occlusion, the lower jaw can be shifted forward using the spacers. These spacers can be crimped on the appliance, so that the lower jaw can be precisely shifted into bilateral neutral occlusion.
The spacers are attached to the thinnest telescopice tube. Fine corrections can be carried out by shifting the connecting element.
