Spring Aligner with Lingual Extensions

This modified version of the spring clip adds .036 lingual extensions to aid in retention.  For this spring aligner where correction is needed, we create a digital version of the dentition and move the teeth into ideal position with the aid of CAD software. We then 3D print out the model and create the appliance providing excellent results.

Treatment & Care

Four-week appointment intervals are recommended. At each appointment, appliance fit should be evaluated and orthodontic correction monitored. Interproximal reduction, as well as appliance adjustment, may be necessary. Patients should wear 22 hours a day and clean daily with toothpaste to prevent the buildup of plaque and odor. Avoid efferdent and other effervescent solutions, as it may erode components on the appliance.  It is recommended to use products like DentaSoak or Retainer Splash.
