“How long do I have to be in braces?” This question ranks right up there with “how much is this going to cost?” when new patients are discussing orthodontic treatment. Your answer to the first question might soon be, “about 38 percent shorter time than in the past,” thanks to the results shown when treatment is enhanced with OrthoAccel’s AcceleDent System. The AcceleDent system has been in use in Europe and Australia since 2009, and received U.S. FDA clearance in November 2011. This article looks at the physics and technology behind the system, and discusses several patient-success stories of three U.S. orthodontic providers.
Static vs. Dynamic Forces
Day-to-day living subjects our bone structures to continuous cycles of deposition and resorption. These cycles go out of balance when bone is damaged due to breakage and might also contribute to osteoporosis. Studies have shown that treatment consisting of non-invasive mechanical intervention, in the form of low-level vibratory forces, not only decreases bone-density loss but also reverses the process. This field is now called micro-pulse therapy and has been investigated and applied to orthodontic treatment.
Traditionally, orthodontic appliances rely on the application of static forces to induce micro-movement of a tooth and the subsequent alveolar bone remodeling. Both osteoblastic (tension) and osteoclastic (compression) activity takes place as the desired movement is accomplished, and the treatment time depends directly on the bone remodeling rate. Many different approaches have been evaluated to increase the speed of movement and thus decrease treatment time, from chemical and biological mediators (whose development takes decades and may have side effects) to surgical intervention and the well-documented use of temporary anchor devices (TADs) for certain cases. However, in recent years clinical studies involving dynamic forces, such as applied through micro-pulse therapy, have
