Turn the SDDA screws from outside to inside 1 turn every 3 days (unless otherwise instructed) with the key provided. It is recommended to do turns at bedtime, since teeth do most of their moving immediately following the activation.
Once the molars are moved, brackets will be added to start retracting the second bicuspid teeth into the corrected positions. When the first bicuspids are ready to be moved into the corrected position, the appliance will be converted to a holding appliance. The holding appliance will stay in place until the rest of the teeth are ready for braces.
Patients occasionally experience tooth sensitivity while wearing the SDDA. This is normal since the function of the appliance is moving the molar teeth to correct the malocclusion. Treat discomfort with over the counter pain medication if needed. If patient experiences severe pain, contact our office.
Initially the bands on the SDDA may cause sores by rubbing against the inside of the cheeks. Use Peroxyl or warm salt water rinses (1tspn per 8oz water) three times daily to sooth. Place wax over the offending bracket. Eventually calluses will form.
Patients will often notice that their “bite” feels different. This is normal and will end once distalization is complete. The patient will quickly adapt to their new bite.
Make sure the SDDA is kept clean. Brushing and flossing the banded molars and bicuspids is important! It is recommended to use a Water-Pik to aid in cleaning the appliance. If the gum tissues begin to swell around the appliance because of poor hygiene, contact our office.
If the appliance should become loose, usually from a broken band, call our office immediately. DO not continue to turn the appliance if any looseness is visible.
If the patient feels no tightening in the mouth after the expander is turned, stop turns and contact our office during normal office hours to be checked.
Any questions regarding your SDDA should be directed to the orthodontic staff.
