Since the mandible can go through a vast number of different movement paths, Posselt decided to start by studying the "border movements", a term he uses to denote the mandible's capacity for movement. Then he compared these with the habitual movements of the mandible. From the investigation, he concluded that:
Computerised cephalometrics is the process of entering cephalometric data in digital format into a computer for cephalometric analysis. Digitization (of radiographs) is the conversion of landmarks on a radiograph or tracing to numerical values on a two- (or three-) dimensional coordinate system, usually for the purpose of computerized ...
The terms alveolar border, alveolar crest, and alveolar margin describe the extreme rim of the bone nearest to the crowns of the teeth. [ 7 ] [ 8 ] [ 9 ] The portion of alveolar bone between two adjacent teeth is known as the interdental septum (or interdental bone).
The mylohyoid line is a bony ridge on the internal surface of the body of the mandible. The mylohyoid line extends posterosuperiorly. The mylohyoid line continues as the mylohyoid groove on the internal surface of the ramus. The mylohyoid muscle originates from the anterior (front) part of the mylohyoid line. [1]
In human anatomy, the facial skeleton of the skull the external surface of the mandible is marked in the median line by a faint ridge, indicating the mandibular symphysis (Latin: symphysis menti) or line of junction where the two lateral halves of the mandible typically fuse in the first year of life (6–9 months after birth).

Moyer's mixed dentition analysis was created in 1971 by Robert Moyers.This an analysis that is used in dentistry to predict the size of the permanent premolars and canines by measuring the width of the permanent incisors.
This nerve runs inside the mandible, within the inferior alveolar canal below the mandibular teeth, giving off branches to all the lower teeth (inferior dental plexus). [ 5 ] [ 6 ] The oral mucosa of the gingiva (gums) on the facial (labial) aspect of the maxillary incisors , canines and premolar teeth is innervated by the superior labial ...
In head and neck cancer, Ohngren's line is a line that connects the medial canthus of the eye to the angle of the mandible. [1]The line defines a plane orthogonal to a sagittal plane that divides the maxillary sinus into (1) an anterior-inferior part, and (2) a superior-posterior part.
