Figures & data
Table 1. Basic data and occlusal characteristics of Osteogenesis imperfecta (OI) patient sample and healthy age- and gender-matched controls.
Figure 1. Dental arch measurements. 1. Upper arch length from the extreme labial surfaces of the incisors perpendicular to a line connecting the extreme mesial points of the first permanent molars. 2. Upper inter-canine width, between the crown tips. 3. Upper inter-premolar widths, between the palatal cusp tips of both first and second premolars. 4. Upper inter-molar width, between the mesiopalatal cusp tips of first permanent molars. Similarly: 5. Lower arch length, 6. Lower inter-canine width, 7. Lower inter-premolar widths, 8. Lower inter-molar width.
Figure 2. Palatal height measurements. (A) The black line marked B indicates the cross-section level in (B), and the white line marked C indicates the cross-section level in (C). B) Anterior palatal height measured from the mid-palate (1) to two reference lines: a line (2) drawn at the gingival margin level of the first premolars, and a line (3) on their palatal cusp tips. C) Posterior palatal height measured from the mid-palate (4) to two reference lines: a line (5) drawn at the gingival margin level of the first permanent molars, and a line (6) on their mesiopalatal cusp tips.
