The application of adjustable intermaxillary forces
- for Class II correction ("internal headgear")
- to create space or anchorage in the upper jaw and
- (also unilateral) closure of gaps in the mandible (aplasia) has always been the wish of every practitioner
In contrast to elastics, where the force development becomes greater and more vertical with increasing mouth opening (undesirable), the FD develops its horizontal force a few millimetres before mouth closure. When the mouth is opened, it slides passively, powerlessly and completely backwards.
As the Flex spring rod can be shortened to any required length, there is no need to purchase graduated assortment sizes.
As well as being able to be adjusted to any desired size, this spring rod can also be thinned to any diameter.
This means that forces between 50 and 1000 grams (0.5-10 N) can be freely adjusted. Even after several months of uninterrupted treatment, the loss of force is less than 5%.
Let yourself and your patient be impressed by this ingenious technology. Up to 1 mm of physical tooth movement per month is standard with the FD.
Ideal even with little patient co-operation or only one-sided application.
Plasma welding guarantees robustness as well as durable and inert quality without soldering.
The prefabricated sliding bow, the unique measuring gauge and the openable locking piece make installation child's play.
