A lack of bony support for the soft tissues in this region will subsequently produce the depression, known as paranasal hollowing. This indicates a low level antero-posterior maxillary deficiency. Maxillary deficiency usually manifests as an increased naso-labial angle, although this is not a credible indication due to factors such as a short upper lip and/or proclined incisors. Another method to predict if a patient has maxillary deficiency is by the ‘scleral show and eyelid shape.’ The lower eyelid normally rests at the inferior border of the iris, without any sclera showing. If there is any sclera showing, then this is a good sign of infraorbital rim deficiency and maxillary antero-posterior deficiency, two manifestations that are usually seen in Class III patients. Orientation
When a jaw is abnormally oriented, malrotations occur. These malrotations are classified according to the axis on which the abnormal rotation occurs. When a jaw is malrotated around the transverse facial axis, it is said to have abnormal pitch. When malrotated around the anteroposterior axis, the jaw has an abnormal roll, a condition also known as cant. Finally, when a jaw is malrotated around the vertical axis, it has abnormal yaw. It can occur in maxilla and/or mandible and could result due to abnormal growth of the jaws in itself or as compensatory growth. Shape
Shape refers to figure, the geometric characteristic of an object that is not size, position, or orientation 5. A jaw with abnormal shape is said be distorted. Completeness
Completeness means the wholeness of the jaw.
Microgenia can be presented when there is inadequate bone depth at the apex of lower anteriors or the base of mandible and vice versa. Position
TransverseA transverse jaw position is known as Laterognathia. This term describes a lateral bite in the lower jaw  and is often associated with a unilateral crossbite at an early age  This can lead to bone development of an asymmetrical mandibular ramus resulting in asymmetry in the whole of the lower face. Treatment of laterognathism is either possible with orthodontic tooth movement or a surgical relocation of the lower jaw. VerticalOne of the ways in which a jaw can develop abnormally is in the vertical dimension. Abnormal growth can occur in the maxilla and the mandible. The jaw is usually loosely used to refer to the mandible (considered the lower jaw). However, the maxilla is also a jaw and should thus be referred to in this respect as well. The vertical jaw abnormalities relating to the mandible are in relation to excessive vertical growth and excessive horizontal growth, measured by the maxillary-mandibular plane angle (MMPA). The vertical jaw abnormalities relating to the maxilla are in relation to excessive downward displacement (EDD) and insufficient downward displacement (IDD). These terms used to previously be known as vertical maxillary excess and deficiency. This nomenclature changed because excess and deficiency typically refer to size. Whereas when assessing this clinically, one would measure the distance between the central incisors and the upper lip, which, in fact, denotes position rather than size.
