Treatment & Care
The spring must be reactivated after the tooth has retracted approximately 1.5 – 2 mm: the operator activates the distal screw as required so that it compresses the spring again (after distalization has begun, activation should be carried out, on average, every 30 – 45 days). The springs can be reactivated each month through the expansion screws integrated into the device. The pre-welded tube on the molar band enables the screw arm to slide smoothly with total control of the direction of distalization. Once the desired amount of distalization is achieved, an eyelet is available on the end of the slider to tie a ligature wire from the band to the appliance to hold the movement.
Distalization Using the FAST BACK Expansor
This appliance should be cleaned every day with toothpaste and a soft toothbrush, morning and night. Encourage the patient to give sufficient time to clean thoroughly around the appliance, gums, teeth, and bands to maintain proper hygiene and prevent inflammation. 3 minutes is recommended.
