title: The first cervical vertebra as an indicator of mandibular growth.
abstract: The association between the morphology of the first cervical vertebra, the atlas, and the direction of mandibular growth is studied by analysing two sets of lateral roentgenocephalograms--one comprising 18 non-treated children and another comprising 18 orthodontically treated subjects divided into three groups with regard to mandibular growth rotation. Among the non-treated cases there was a significant correlation between horizontal growth of the mandible during a two-year period and the initial height of the atlas dorsal arch. The treated subjects with forward mandibular rotation during treatment, demonstrated a significantly higher pretreatment dorsal arch than the subjects with either no rotation or a backward mandibular rotation.
