A cross‐sectional analysis of Wits and Riedel in adults with skeletal III malocclusion: How informative are they?

Abstract

There is a positive relationship between ANB and Wits; however, neither correlated well with a purer antero-posterior assessment (AF-BF). Furthermore, variations in the vertical skeletal measurements affect the strength of agreement. Caution is advised in the interpretation of antero-posterior analysis especially in the presence of vertical discrepancy.

The Likelihood of Orthognathic Surgery After Orofacial Cleft Repair

“…33,[50][51][52][53] Harvold unit difference is more consistent with clinical impressions of maxillary and mandibular positioning compared to Steiner cephalometric analysis and Wits appraisal, which may explain why surgeons prefer obtaining multiple measurements to guide decision making. [54][55][56] Despite the availability of objective measures, however, there is still a wide degree of subjectivity in determining satisfactory facial aesthetics for the surgeon and patient. Furthermore, normal variation of facial contour among races can affect the objectivity of these measurements.…”

“…Steiner cephalometric measurement standards were based on Caucasian patients; however facial morphology standards are different for different ethnic groups and gender 33,50–53 . Harvold unit difference is more consistent with clinical impressions of maxillary and mandibular positioning compared to Steiner cephalometric analysis and Wits appraisal, which may explain why surgeons prefer obtaining multiple measurements to guide decision making 54–56 . Despite the availability of objective measures, however, there is still a wide degree of subjectivity in determining satisfactory facial aesthetics for the surgeon and patient.…”
