An intra-oral vibrating device with improved patient comfort is capable of shortening the duration and increasing the effectiveness of the orthodontic treatment.
Background:
Traditional braces and retainers (”fixed orthodontics”) apply a constant and stagnant force and 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. Dental researchers have postulated that a pulsating/non-static force might move teeth more rapidly and ease the discomfort of traditional orthodontics. Several studies with pulsating devices have demonstrated that this is the case. The leading marketed pulsating device utilizes an external control and power source that is inconvenient and uncomfortable for the patient.
Technology Overview:
University at Buffalo researchers have developed an intra-oral (not visible) vibrating device that works in conjunction with braces or aligners to accelerate movement of teeth. The device compromises 1) a harmonic function generator and micro-chip vibrators fitted over the teeth and aligner (or braces). The device is capable of delivering targeted and adjustable (frequency and duration) vibration to teeth. It is anticipated that this design may be more comfortable for patients and improve treatment compliance, without requiring a bulky power supply protruding from a patient's mouth.
