What does the alveolar process support?

The alveolar bone, also called the alveolar process, is the part of the jaw that holds the teeth. The bone here supports the roots of the teeth and keeps them in place.

Where is the alveolar process on the skull?

maxilla The alveolar process (alveolar bone) is the thickened ridge of bone that contains the tooth sockets on bones that bear teeth (maxilla and mandible). On the maxilla, the alveolar process is a ridge on the inferior surface. It makes up the thickest part of the maxilla.

How many alveolar processes are located on the mandible?

The coronoid process is anterior and the condyloid process is posterior; the two are separated by the mandibular notch. The ramus is bound by two surfaces and four borders and contains two processes.

What is alveolus in tooth?

Dental alveoli are sockets in the jaws in which the roots of teeth are held in the alveolar process of maxilla with theperiodontal ligament. The lay term for dental alveoli is tooth sockets. A joint that connects the roots of the teeth and the alveolus is called gomphosis.

What is the alveolar process composed of?

compact bone Although the alveolar process is composed of compact bone, it may be called the cribriform plate because it contains numerous holes where Volkmann’s canals pass from the alveolar bone into the PDL. The alveolar bone proper is also called bundle bone because Sharpey’s fibres, part of the PDL, are inserted there.

How is alveolar bone formed?

The alveolar bone begins to first form by an intramembranous ossification with in the ectomesenchyme surrounding the developing tooth. This first formed bone is called as woven bone is less organized and is replaced with more organized lamellar one. When a deciduous tooth is shed, its alveolar bone is resorbed.

Where is the gingiva?

oral cavity The gingiva (gums) are found in the oral cavity of humans surrounding part of their teeth. They are comprised of mucosal tissue which covers the alveolar processes of the mandible and maxilla and finish at each tooth’s neck.

Where is the alveolar ridge located?

The alveolar ridge is a small protuberance just behind the upper front teeth that can easily be felt with the tongue.

What is fenestration and dehiscence?

Fenestration is the condition, in which the bony coverage of the root surface is lost, and the root surface is only covered by the periosteum and gingiva. In such lesions, marginal bone is intact. When this bone defect spreads toward the marginal bone, it is called dehiscence.[1]

What is alveolar resorption?

Alveolar ridge resorption following tooth extraction is an extremely common and generally inevitable side effect of removing a tooth from its socket in the alveolar ridge.

What is alveolar margin?

The alveolar ridge (/ælˈviːələr, ˌælviˈoʊlər, ˈælviələr/; also known as the alveolar margin) is one of the two jaw ridges, extensions of the mandible or maxilla, either on the roof of the mouth between the upper teeth and the hard palate or on the bottom of the mouth behind the lower teeth.

What is Gomphoses?

A gomphosis is a fibrous mobile peg-and-socket joint. The roots of the teeth (the pegs) fit into their sockets in the mandible and maxilla and are the only examples of this type of joint.

What is the frontal process of maxilla?

The frontal process of maxilla is a strong plate, which projects upward, medialward, and backward from the maxilla, forming part of the lateral boundary of the nose.

What cells are found in the periosteum?

The inner layer of the periosteum contains osteoblasts (bone-producing cells) and is most prominent in fetal life and early childhood, when bone formation is at its peak.

When is cellular cementum formed?

Formation of the matrix for cellular cementum appears to be induced by exposure of the inner layer of the epithelial root sheath to the mesenchymal cells in the dental follicle.

What is gingiva made of?

The gingiva is part of the masticatory mucosa that provides an internal defense mechanism against pathogens and mechanical stress. It is composed of a dense, vascular fibrous tissue with a keratinized stratified squamous epithelium.

What are parts of gingiva?

Gingiva comprises part of the masticatory oral mucosa that covers alveolar bone surrounding the tooth and is divided in three anatomical areas: marginal gingiva comprises the free edge of gingiva surrounding the tooth and covers the internal walls of gingival sulcus, attached gingiva is firmly bonded to the underlying

What is alveolar membrane?

The alveolar membrane is the gas exchange surface, surrounded by a network of capillaries. Across the membrane oxygen is diffused into the capillaries and carbon dioxide released from the capillaries into the alveoli to be breathed out. Alveoli are particular to mammalian lungs.

What are Hemiseptal defects?

Hemiseptal defects i.e., vertical defects in the presence of adjacent roots and where half of a septum remains on the tooth, represents a special case of one-wall defects and the treatment is always a challenge despite the various periodontal regenerative therapies.

What does Abfraction mean?

Abfraction (AF) is the pathological loss of tooth substance caused by biomechanical loading forces that result in flexure and failure of enamel and dentin at a location away from the loading.

What is dehiscence in perio?

18-8) A dehiscence is loss of alveolar bone on the facial (rarely lingual) aspect of a tooth that leaves a characteristic oval, root-exposed defect from the cementoenamel junction apically. The defect may be one or two millimeters long or extend the full length of the root.

What causes alveolar bone?

Although most premature tooth loss from non-systemic disease results from trauma or caries, the cause of advanced alveolar bone loss is often not readily apparent. Local factors (periodontitis, trauma, and infection secondary to caries) account for the majority of cases of premature bone loss.

What is a periodontist?

A periodontist is a dentist who specializes in the prevention, diagnosis, and treatment of periodontal disease, and in the placement of dental implants. Periodontists are also experts in the treatment of oral inflammation.

What causes alveolar resorption?

Loss of teeth results in irreversible alveolar bone resorption, and untreated dental disease causes alveolar bone lysis that ultimately leads to loss of teeth.
