Table 2.

Width dental, gingival-alveolar, skeletal-basal (transverse plane). Widths (in mm) in the anterior (54–64 and 14–24) and posterior (16–26) regions at five different levels of the maxilla. The dental width, the gingival/alveolar width, the width 2 mm and 4 mm cranial to the gingival/alveolar level and the skeletal/basal width are shown. M Mean, SD standard deviation, GM gingival margin, patient groups PG 1(early) and PG 2 (late)
