Thirty charts of orthodontic patients with pretreatmentTMD symptoms were selected at random.Gender, age, sex, ethnicity, SNA, SNB, ANB,Wits, interincisal angle, missing teeth, prior orthodontic treatment, crossbites, Angle's Class and maxillary and mandibular length were tabulated and analyzed for patterns. The results revealed a clear pattern of excessive mandibular length relative to maxillary length.
