Cone-beam CT study reveals optimal sites for mini-screw placement in mandibular symphysis, suggesting age-related changes.
An age-related increase in mandibular symphysis height and depth was observed. With respect to the ideal MS dimensions and the optimal site for orthodontic skeletal anchorage, MSs with a length of 20-28 mm may be placed vertically and deep in the lower vestibule of the mandibular symphysis, in the region of the lateral incisor and canine.
