Occlusal rests 0.7 mm spring hard, segmented arch wire for lingual technique out of 0.8 mm rematitan® SPECIAL, single ended pendulum spring with mesially open U-loop, lingual brackets
Function:
Leveling of the incisors through the segmented arch wire with simultaneous anchorage of the appliance
Description:
The placement of the segmented wire in the anterior region makes the extension of the acrylic base wider
The occlusal rests are fixed as usual on the premolars or deciduous molars. The U-loop of the pendulum spring is open mesially and the wire ends simple in the molar bands. These have a double tube. One slot serves for receiving the pendulum spring and the other for the later fixation of a TPA after the distal molar movement.
The segmented wire for the lingual technique is fixed passively into the bracket slots. These can be either already bonded directly in the patient's mouth and be represented well on the working cast, or fixed onto the cast for indirect bonding.
The anterior segmented arch wire should be employed mainly for passive anchorage rather than for leveling the incisors.
