One of the TADs, the i-station, enables three-dimensional tooth movements such as distalization, mesialization, intrusion, extrusion, expansion, constriction, distal rotation, and mesial rotation. The ability to move teeth in these way makes it possible to treat some cases that were previously cured only by orthognathic surgery, with orthodontic treatment alone.
As mentioned above, the i-station has great potential, but it only works when the screw is stable.
In cases where the bone width is extremely thin, the stability of the screw cannot be obtained, and in cases where a complicated force system is required, the screw is overloaded and the risk of falling off is unavoidable. We need to be able to handle such cases.
To overcome this situation, a new i-station with an upper unit "platform" that can be installed over up to four screws has been developed. Of course, the four screws do not have to be parallel.
Besides, the new superstructure can be freely bent in three dimensions so that it can be placed in the desired position. Therefore, the teeth can be accurately controlled to the target position. No complicated activation is required.
We will unveil the secret story behind the development of the i-station while introducing cases under development as to why such a i-station was developed.
Please take a look at the newly developed i-station.
