These elastics are used for bite closure, occlusion detailing etc. This type of elastic must be worn 24 hours a day
and must be replaced every 12 hours due to memory and elasticity. The force can vary from 2 to 6.5 ounces (1
ounce=28.35 g) and they can be placed in many configurations (box, trapezoid, delta, spaghetti, etc.). It all depends
on the required vector. The size of the elastic can vary from 1/8" to 5/16'.
