Regaining Bicuspid Space

Gaining Space for a Rotated Bicuspid

 You often need to regain space to fit a rotated lower bicuspid in the mandibular arch. It is possible to distalize the molar and at the same time derotate and fit the bicuspid in the arch. Remember that to move back a molar the occlusion on that molar must be controlled to avoid any interferences, composite molds can be used. The force required to move back a molar is around 150 g, a medium coil delivers around 150 g (may vary slightly from one manufacturer to the other). The coil should be reactivated every 4 weeks to compress the coil using a metal ligature until the desired movement is achieved. The bicuspid will have to be torqued onece in the arch.
