the postcanines sit in a longitudinal groove flanked by a lateral edge (the "alveolar margin") the alveolar (upper) margin forms an angle with the ventral (lower) margin (like in archaeocetes) the ventral margin is straight in the posterior half of the mandible; teeth have longitudinal ridges
A profile of a smile, exhibiting a deviated dental midline about 2 mm to the left (the midline is measured as the mandible in relation to the maxilla.Even though the teeth are in an edge-to-edge position, the teeth are in maximum intercuspation; this patient possesses a Class III occlusion.
The anterior margin of sternocleidomastoid Superior boundary (base) The lower border of the body of the mandible, and a line extending from the angle of the mandible to the mastoid process
The facial artery typically crosses the inferior border of the mandible just anterior to the masseter muscle's insertion. In most instances, this crossing occurs at or in close proximity to the antegonial notch. This anatomical association has clinical relevance in various surgical procedures involving the face and mandible.
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).
It is located between the lateral aspect of the mandible and the medial aspect of the masseter muscle and its investing fascia. The term is derived from sub-meaning "under" in Latin and masseteric which refers to the masseter muscle. The submasseteric space is one of the four compartments of the masticator space. [1]
Growth of mandible depends on the normally developing condyles and the muscle function For example, trauma or infection that affect mastoid, middle ear or the joint will result in ankylosis of temporomandibular joint leading to mandibular micrognathia. [31] Macronagthia; Macronagthia is a condition of abnormally large jaws.
The condyloid process or condylar process is the process on the human and other mammalian species' mandibles that ends in a condyle, the mandibular condyle.It is thicker than the coronoid process of the mandible and consists of two portions: the condyle and the constricted portion which supports it, the neck.
