What does the mandible articulates with?

The condylar process has an articular surface (the condyle), via which the mandible articulates with the articular tubercle of the temporal bone to form the temporomandibular joint.

Which is the most common lesion of mandible?

Odontoma is the most common odontogenic tumor of the mandible, accounting for approximately 67% of all cases (,6). The lesion consists of various tooth components, including dentin and enamel, which have developed abnormally to form a “hamartomatous” lesion.

What part of the mandible articulates with the TMJ?

The disc articulates with the mandibular fossa of the temporal bone above and the condyle of the mandible below. The disc divides the joint into two sections, each with its own synovial membrane. The disc is also attached to the condyle medially and laterally by the collateral ligaments.

Which part of the mandible articulates with the cranium?

The lacrimal bone along with the sphenoid, ethmoid, and frontal bones make up the medial wall of the orbit. which region of the mandible articulates with the cranium? The mandibular condyle of the mandible is a knob like projection that articulates with the mandibular fossa of the temporal bone.

What articulates with the maxilla?

[3] The maxilla connects with surrounding facial structures through four processes: alveolar, frontal, zygomatic and palatine. It articulates superiorly with the frontal bone, the zygomatic bone laterally, palatine bone posteriorly and with the upper teeth through the alveolar process inferiorly.

How common are jaw lesions?

Central giant cell granuloma is a relatively common lesion of the jaw and typically occurs in adolescents and young adults (75% of patients are less than 30 years old) (,7).

What is periapical Cemento osseous dysplasia?

Periapical cemento-osseous dysplasia (PCOD) is a rare benign lesion, often asymptomatic, in which fibrous tissue replaces the normal bone tissue, with metaplasic bone and neo-formed cement.

What is the depression in the temporal bone that articulates with mandible?

The mandibular fossa
The mandibular fossa, also known as the glenoid fossa in some dental literature, is the depression in the temporal bone that articulates with the mandible.

What is the Lingula of mandible?

The lingula of the mandible (also known as Spix spine) is a triangular bony projection or ridge on the medial surface of the ramus of the mandible, immediately superior to the mandibular foramen. It provides attachment for the sphenomandibular ligament 1,2.

Do jaw tumors need to be removed?

If the x-ray shows the tumor has grown into the jaw bone, a large part of the jaw will need to be removed in an operation called a segmental mandibulectomy.

Can a jaw cyst be cancerous?

Odontogenic keratocyst: This slow-growing, benign cyst most often develops in the lower jaw near the third molars and can be destructive to nearby areas. It frequently recurs and, rarely, may become malignant.

What is a mandibular lesion?

Mandibular lesions are myriad and common. The presence of teeth results in lesions that are specific to the mandible (and maxilla) and a useful classification that defines them as odontogenic or non-odontogenic.

What is an ovoid lesion on the posterior mandible?

The radiological aspect includes ovoid, well-defined radiolucent cortical defects on the lingual surface of the posterior mandible usually measuring less than 2 cm. This location is typical and the lesion contains fat or salivary gland tissue.

What is the pathophysiology of lesions in the jaw?

Most lesions in the jaws occur in the ramus and posterior body of the mandible. It is important to recognize the hemorrhagic potential of these lesions because extraction of a tooth adjacent to an arteriovenous malformation may result in lethal exsanguination (, 11 ). The clinical features of arteriovenous malformations are variable.

What is the outer surface of the mandible called?

The outer cortical bone of the mandible is known as the buccal surface, and the inner cortex is known as the lingual surface. Between the two cortices, there is trabecular bone and the alveolar canal, which carries the mandibular nerves.
