Sequence of the distraction
1. A week after surgery, the activation of the Smile Distractor is started with the patientkey (IT0444). Turn the blocking nut a little backwards so that the module isn’t blocked by the nut. Then turn the distractor open until resistance can be felt on the bone and then turn an additional once or twice.
During the activation period (1 to 2 weeks), the patient must turn the module 1/3 of a rotation twice a day; this is about 0.6 mm opening per day. With each turn, a new colour appears.
2. After the activation period, the blocking nut must be tightened with some force. The easiest way to do this is with 2 patient keys: one on the module; and 1 on the locking nut; and then turn them in opposing directions. Leave the distractor in place for a period of 3 to 6 months.
