About the Book

Materials & methods. Data was obtained from the Burlington Growth Centre and the Michigan Growth Center. The individuals were un-treated orthodontically, with records available at ages 9-18. Short face height was determined cephalometrically as the ratio of upper face height (N-Sn') to lower face height (Sn'-Me) >0.85. Carey's analysis was used to assess crowding, while arch width was measured as the horizontal distance between the cusp tips of contralateral teeth. Comparisons were conducted using t-tests or Mann-Whitney U tests, followed by multi-variate analysis.Purpose. To determine whether patients with small lower face height have more arch constriction or crowding relative to normal face height individuals.Summary of results & conclusions. Maxillary arch space was less in the overclosed group vs. controls at each age of the permanent dentition, as was mandibular arch space at age 18. The overclosed group also had narrower anterior maxillary and mandibular arch widths at age 18. Longitudinally, the overclosed group developed more crowding and anterior arch constriction over time in both arches vs. controls.
