The Stafne defect (also termed Stafne's idiopathic bone cavity, Stafne bone cavity, Stafne bone cyst (misnomer), lingual mandibular salivary gland depression, lingual mandibular cortical defect, latent bone cyst, or static bone cyst) is a depression of the mandible, most commonly located on the lingual surface (the side nearest the tongue).
The articular disk of the temporomandibular joint is a thin, oval plate made of non-vascular fibrous connective tissue located between the mandible's condyloid process and the cranium's mandibular fossa. Its upper surface is concavo-convex from before backward, to accommodate itself to the form of the mandibular fossa and the articular tubercle ...
Cephalometric analysis depends on cephalometric radiography to study relationships between bony and soft tissue landmarks and can be used to diagnose facial growth abnormalities prior to treatment, in the middle of treatment to evaluate progress, or at the conclusion of treatment to ascertain that the goals of treatment have been met.

A panoramic radiograph is a panoramic scanning dental X-ray of the upper and lower jaw.It shows a two-dimensional view of a half-circle from ear to ear. Panoramic radiography is a form of focal plane tomography; thus, images of multiple planes are taken to make up the composite panoramic image, where the maxilla and mandible are in the focal trough and the structures that are superficial and ...
Rarely, the mylohyoid muscle may originate partially from other surfaces of the mandible. [2] The posterior (back) part of this line, near the alveolar margin , gives attachment to a small part of the superior pharyngeal constrictor muscle , and to the pterygomandibular raphe .
Problems with morphogenesis during embryonic development can lead to the mandibular fossa not forming. [2] This may be caused by mutations to SOX9 or ALK2. [2] If the mandibular fossa is very shallow, this can cause problems with the strength of the temporomandibular joint. [5] This can lead to easy subluxation of the joint and trismus (lock ...
The mandible in particular has the most differential typical growth anomalies than any other bone in the human skeleton. This is due to variants in the complex symmetrical growth pattern which formulates the mandible. [1] The mandible in particular plays a significant role in appearance as it is the only moving part of the facial skeleton.
It is suggested that the temporomandibular joints (TMJ) limit the border movements of the mandible. In 1957, [3] [4] he used a gnatho-thesiometer to analyse the areas of movement for three points on the mandible in three main planes. Five experimental subjects with practically all their teeth present had their mandibular movements analysed.
