Sh. Beckmann et al., ALVEOLAR AND SKELETAL DIMENSIONS ASSOCIATED WITH LOWER FACE HEIGHT, American journal of orthodontics and dentofacial orthopedics, 113(5), 1998, pp. 498-506
In this study, the relationships between the lower face height and the
structure of the frontal alveolar and basal bone were investigated. T
he areas and the dimensions of the anterior alveolar and basal midsagi
ttal cross-sectional bone from the maxilla and the mandible were recor
ded on lateral cephalograms from 460 untreated adults. An index was ca
lculated dividing the sagittal by the vertical dimension of the midsag
ittal cross-sectional area. The subjects with a normal overbite betwee
n 0.5 and 4 mm (N = 165) were divided into three groups according to t
he lower face height. A larger lower face height coincided with a larg
er maxillary alveolar and basal area and with a smaller mandibular alv
eolar index. Correlations between the lower face height and the maxill
ary alveolar index and the mandibular alveolar and basal area were low
. It is concluded that long-faced subjects have a large mandibular alv
eolar height, which is more associated with a narrowed shape than with
a large volume of the symphysis.
