From: 3D assessment of mandibular skeletal effects produced by the Herbst appliance
Statistical analysis of the additional skeletal effect. The left column indicates that approximately 85–100% of cases in the Herbst group have 0.5 mm additional condylar changes compared to the normative group from T1-T2 and that these changes are statistically significant. The right column indicates that only 40–50% of cases in the Herbst group have 1.5 mm additional condylar changes compared to the normative group from T1 to T2, and that these changes are not statistically significant. The additional changes at the chin are not statistically significant at both 0.5 mm and 1.5 mm cut-off values
