Table 1.
Details of craniofacial assessment.
| Extra-oral | ||
|---|---|---|
| The profile view | Convex / straight / concave | Convex when a line dropped from the forehead to the base of the upper lip and a second line extending from that point downward to the soft-tissue pogonion formed an acute angle; straight when the angle was a nearly straight line and concave when the angle was obtuse |
| The Frontal view | Short / normal / long lower face | Short lower face when the lower third of the face was shorter than average; normal lower face when the lower third was almost equal to the average and long lower face when the lower third was longer than average. The mid-third of the face was used as a reference |
| The mandiular plane angle | Flat / normal / steep | Visualized by placing a mirror handle along the border of the mandible, classified as flat, normal or steep. |
| Intra-oral soft tissue | ||
| Tonsil size | Normal / hyprtrophic | Normal or hypertrophic when the tonsils caused a greater than 50% obstruction, according to the Brodsky grade |
| Relative tongue size | Normal / large | Normal or large when imprints of the teeth were seen on the lateral margins of the tongue, which is relative tongue size in realtion to the dental arch, rather than a macroglossia |
| Intra-oral dentition | ||
| Shape of upper arch | Tapered / ovoid / square | According to the MBT system |
| Shape of lower arch | Tapered / ovoid / square | According to the MBT system |
| Height of palatal vault | High / Normal | The palatal vault was classied as high (deep, constricted, V-shaped palatal arch) and normal (Shallow, U-shaped palatal arch) |
| Molar relationship | Class I / Class II / Class II subdivison / Class III / Class III subdivision | According to the Angle classification, in which the subdivision is the unilateral molar relationship of either Class II or Class III |
| Incisor relationship | Class I / Class II subdivison 1 / Class II subdivison 2 / Class III | According to the British standard incisor classification |
| Vertical occlusion | Reduced overbite / normal / deepbite / reverse overbie | A visual occlusion assessment |
| Amout of overjet | A linear measurement with a ruler |
