Which outcome was observed with the application of 60 Hz frequency vibration in orthodontic treatment?

The application of 60 Hz frequency vibration in orthodontic treatment has been found to increase the speed of tooth movement. This phenomenon can be attributed to the way vibrational forces influence the biological processes involved in tooth movement. When vibrations are applied at this frequency, they stimulate the periodontal ligament, enhancing the remodeling of alveolar bone and facilitating more efficient tooth movement.

Research indicates that these vibrations can increase the rate of osteoclast and osteoblast activity, which are critical for bone resorption and formation around the tooth roots. As a result, orthodontic forces can lead to accelerated tooth movement when accompanied by this type of vibrational stimulation.

While reduced pain, improved patient compliance, and decreased treatment duration are important factors in orthodontic treatment, the primary mechanism of action observed specifically with 60 Hz vibrational frequency is the enhanced speed of tooth movement. This understanding is crucial for orthodontists considering adjunct therapies to optimize treatment outcomes for their patients.
