TS2
TS2 is a new improved device for the Rapid Open Bite Correction in about 4-6 months.
The TS2s main features are:- Nine rounded reminder protrusions prevent tongue thrusting.
- 80-gauge mesh bonding pad for increased shear bond strength.
- Six Undercuts for cross bite elastics in lateral open bite treatment that commonly requires maxillary expansion.
- Very small tongue inhibitor for good oral hygiene.
How it works
The basic mechanism of action is that the TS2s produces a negative conditioning reflex response for anterior tongue positioning, like a so-called “hot-stove effect”.
However, due to the rounded ends of the 9 protrusions the tongue is not lacerated, nor is the operator’s glove or skin.
The feeling against the finger is one of a coarse sandpaper, acting simply as a reminder for the tongue to stay retracted away from the open bite.
This permits the TS2s to work effectively in conjunction with the anterior box elastics (5/16”, 4.5oz) for rapid open bite closure (ROC).
In lateral open bite patients, with lateral open bite, where the TS2s are placed at the premolars and molars, it is possible to apply crossbite elastics, generally heavy 1/4”, 4.5oz, to further prevent lateral tongue positioning while maxillary expansion is completed simultaneously.
It is fundamental that the patient is instructed, from the day of TS2 placement, to exercise swallowing with the tongue in the roof of the mouth.
When to use it
TS2s are recommended at all ages including for both early interceptive treatment in children and in adults.
The ideal recommended time of placement is at the time of placement of active self-ligating brackets (that are regularly positioned on the labial aspects).
TS2s and active self-ligating brackets work ideally and synergistically with specialized i-Arch wires that have a higher vertical dimension than horizontal dimension to be closer to the center of resistance for earlier incisor moments of torque and control required for open bite correction.
The archwires incorporate:
- curve of Spee for the lower arches
- reverse compensating curve on the upper arches
to further facilitate incisor re-intrusion.
TS2 incisor re-extrusion is further facilitated by the alignment of the anterior teeth, where a labial box elastic can be placed that also restrains the tongue.
With the use of this light force system, No clinically significant root resorption was found that reduces the unnatural and multi-directional anterior, superior, inferior and lateral tongue forces.
Small Dimensions
The miniaturized size improves patient comfort and facilitates acceptance.
