How often should the expansion screw be turned for optimal results in treatment?

Turning the expansion screw twice a week is the recommended frequency for optimal results in orthodontic treatment involving palatal expansion. This schedule allows for a steady and controlled movement of the teeth and bone tissue, facilitating effective and safe expansion of the dental arch.

Turning the screw too frequently, such as daily, can potentially lead to discomfort and excessive force on the teeth and supporting structures, which may not provide optimal outcomes. Similarly, turning the screw on a less frequent basis, such as weekly or monthly, could slow down the desired expansion and prolong the duration of treatment. Therefore, the twice-a-week schedule strikes a balance between achieving effective expansion and minimizing any adverse effects on the patient.
