Dentists use elastics (rubbers) to complement the displacement of teeth. They are classified as follows:
Elastics type 1: they are placed on the arc for closing spaces an helping the elastomer chains.
Elastics type 2: they are used for the lower molars to upper canine tooth.
Elastics type 3: they are used from the upper molars to lower canine tooth
Elastics can be used in vertical direction to close the frontal open bites or to descend dental pieces that are moved outside.
Elastomer chains are used to close spaces; they are places o e ach braces, generally from molar to molar. There is also placed a chain link on each brace.
Coil Spring
These springs are placed inside an arc, just 2 mm more from the space they should be put on. They are used to separate pieces or to keep the space for the piece that should be placed there.
Bottoms Bottom-shaped metallic pieces used to displace outside teeth get adhered as well as braces. The dentist makes traction with elastics and later places a brace to align the piece. Mostly there are included pieces like the canines, on which there must be made fenestration; a space like a “little window” to place the bottom right there, or the dentist might put surgical cement on the wound to avoid cicatrisation. Nowadays is demonstrated than better than a fenestration is better leave flaps for lateral and top reposition.
