APPLIANCES ARE TOOLS USED TO APPLY

FORCE SYSTEMS

• You can use any imaginable appliance, it can be it fixed, removable,

conventional, lingual or even "invisible".

• The fact is that ALL of them will always be governed by the exact

and immutable laws of physics.

• At the end, our appliances will move teeth by the application of a force

system, which consists in forces, couples, or a combination of

them.
