A team of orthodontists at the University of Texas Health Science Center at San Antonio hopes to speed up and improve orthodontic treatment using a new device called the AcceleDent. The device is being incorporated in an investigational study at the university, which involves 34 patients between the ages of 12 to 40 who need braces. Patients re-ceive standard orthodontic treatment including any necessary tooth extractions, and are fitted for braces. Once their braces are placed, patients are provided with an AcceleDent device, which stands about 4 inches high and features a wafer-thin mouthpiece attached to a small, sleek battery-operated handle. Patients are instructed to place the device in their mouth and bite down for 20 minutes a day during orthodontic treatment. While in the mouth, the device delivers a low-frequency pulsating vibration to the teeth that is not uncomfortable and barely noticeable. The researchers believe the vibratory forces, in combination with standard orthodontic treatment, will enhance the metabolism in bone tissue surrounding the teeth, thus allowing the teeth to move and straighten faster and more effectively. Scientists across the world have documented positive results using vibration therapy in patients with osteoporosis, muscle loss, and joint pain. The researchers of this study believe the application of cyclic loading (controlled vibrations) will not only increase the rate of tooth movement, but will also create a solid foundation of bone and adjacent tissues in the mouth and result in more stable outcomes for orthodontic treatment. It is estimated that the AcceleDent will be marketed in the United States in late 2010.
