PH, vertical distance from the cementoenamel junction to the center of the miniplate anchoring screw (MPAS) at position 1; PD, distance from the outer surface of the labial cortical bone to the tip of the MPASs at positions 1 (PD1) and 2 (PD2); PA, angle of the miniplate placed on the mandibular symphysis; MA, angle made by the two tangents, with one from the most prominent midpoint of the chin and the other from the prominent point on the buccal root surface; CI, confidence interval.
