Patent 9907626 was granted and assigned to OrthoAccel Technologies on March, 2018 by the United States Patent and Trademark Office.
An improved vibrating orthodontic device is provided wherein motor speed is controlled by capacitive sensor, and thus lacks moving parts that are required by encoder use. The improved device also uses a tungsten offset weight, reducing size by more than 50%, yet still produces the needed force. The device is thus smaller, lighter and more robust.
