The present invention provides devices, systems and methods for orthodontic treatment using elastic repositioning appliances while concurrently providing dental and periodontal therapies. Such therapies are traditionally provided with the use of a variety of accessories and devices which are applied
The present invention provides devices, systems and methods for orthodontic treatment using elastic repositioning appliances while concurrently providing dental and periodontal therapies. Such therapies are traditionally provided with the use of a variety of accessories and devices which are applied when the repositioning appliance is removed from the patient's mouth. The present invention eliminates the need for such removal and additional devices by incorporating these therapies into the repositioning appliance.
