An intra-oral vibrating device that is contained in the mouth is capable of shortening and increasing the effectiveness of the orthodontic treatment.
Traditional braces and retainers (”fixed orthodontics”) require an extended period of 2-3 years to move teeth into the desired position. Fixed orthodontic treatment also poses high risks of caries, external root resorption, and decreased patient compliance over time. Multiple studies have found a positive correlation between extended treatment duration and the amount of root resorption experienced by a patient. However, even when no radiographic sign of root resorption is visible, it is accepted that most teeth undergoing orthodontic tooth movement will experience some degree of root resorption followed by repair. Dental researchers have postulated that a pulsating/non-static force might move teeth more rapidly and ease the discomfort of traditional orthodontics. The leading marketed pulsating device utilizes an external control and power source that is inconvenient and uncomfortable for the patient.
An intra-oral vibrating device that is contained in the mouth (not visible) has been developed. This device is capable of shortening and increasing the effectiveness of the orthodontic treatment. Embodiments of the device utilize piezoelectric actuators that can be excited by a voltage function generator (signal generator) given a specific frequency and amplitude. The technology harnesses the energy required to produce mechanical vibrations to stimulate tooth movement completely within a patient’s mouth, i.e., without requiring a bulky power supply protruding from a patient’s mouth.
