What is alveolar crest?
The alveolar crest is the most cervical rim found in the alveolar bone proper. When it is healthy, the alveolar crest is slightly apical to the cementoenamel junction (CEJ) by about 1.5-2 mm. The alveolar crests of the adjacent teeth are also uniform in height along the jaw when they are healthy.
What is the function of the alveolar bone?
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. The alveolar bone has two parts — the alveolar bone proper and the supporting alveolar bone.
Which is the position of the normal alveolar crest?
The normal alveolar bone crest located at a distance of 1 to 2 mm from CEJ towards the apical. If there is a bone loss, the alveolar bone crest located at 2 mm more to the apical from CEJ. The alveolar bone loss is one characteristic of aggressive periodontitis and the onset of the disease at the age of puberty.
What are the three layers of alveolar bone?
Alveolar bone consists of four layers. In addition to the three layers found in all bones, namely periosteum, dense compact bone and cancellous bone, there is a fourth layer called the cribriform plate, which lines the alveolar sockets.
Why is it called the alveolar ridge?
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 does the word alveolar mean?
1 : of, relating to, resembling, or having alveoli especially : of, relating to, or constituting the part of the jaws where the teeth arise, the air-containing compartments of the lungs, or glands with secretory cells about a central space.
Where is the alveolar margin?
What is the hardest calcified substance in the body?
Enamel is the hardest substance in the human body and contains the highest percentage of minerals, 96%, with water and organic material composing the rest. The primary mineral is hydroxyapatite, which is a crystalline calcium phosphate.
What is the ridge behind your teeth called?
Why is my alveolar ridge swollen?
One of the most common causes of swelling on the roof of the mouth is an injury or trauma. Some of the most common causes of trauma include: eating a hard food that may impact the roof of the mouth. eating or drinking an extremely hot item.
Which are the alveolar sounds?
Alveolar consonants are consonant sounds that are produced with the tongue close to or touching the ridge behind the teeth on the roof of the mouth. The name comes from alveoli – the sockets of the teeth. The consonant sounds /t/, /n/ and /d/ are all alveolar consonants.
