The coronal margin of the alveolar process, where the cribriform and cortical plates meet, is the alveolar margin. The alveolar margin is typically 1–2 mm apical to the cementoenamel junction so that there is a band of root cementum residing coronal to the alveolus.
What is the alveolar process teeth?
The alveolar process, which is also called the alveolar bone, is the thick ridge of bone which contains the tooth sockets. The alveolar bone is located on the jaw bones which hold the teeth. In humans, these bones that contain the teeth are the maxilla and the mandible.
What is an 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 the difference between the alveolus and the alveolar process?
1. Alveoli are composed of epithelial layers and extracellular matrix enclosed in capillaries while alveolar sacs are the distal ends of alveolar ducts. 2. The alveoli sacs are formed by a group or cluster of alveoli, and it is there where they communicate while the alveoli are made up of collagen and elastic fibers.
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]
Why is alveolar bone called Cribriform plate?
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.

What is the cavity within the alveolar process that holds the tooth?
On the maxilla, the alveolar process is a ridge on the inferior surface, making up the thickest part of the bone. On the mandible it is a ridge on the superior surface. The structures hold the teeth and are encased by gums as part of the oral cavity.
How can you tell Denestration and dehiscence?
The three features of dehiscence include gingival recession, alveolar bone loss and root exposure. A fenestration is a “window” of bone loss on the facial or lingual aspect of a tooth that places the exposed root surface directly in contact with gingiva or alveolar mucosa.
What is marginal gingiva?
The terminal edge of gingiva (gums) that surrounds the teeth is known as the gingival margin (marginal gingiva). The gingival margin lacks the presence of stippling and the tissue is mobile or not attached to the surface of the underlying tooth.
What is the bone between teeth called?
The portion of alveolar bone between two adjacent teeth is known as the interdental septum (or interdental bone). The connected, supporting area of the jaw (delineated by the apexes of the roots of the teeth) is known as the basal bone.
How teeth are supported in the alveolar bone?
Alveolar bone is that part of the maxilla and mandible which supports the teeth by forming the “other” attachment for fibres of the periodontal ligament (Fig. 1.148). It consists of two plates of cortical bone separated by spongy bone (Fig.
What is the alveolar margin of the process?
The coronal margin of the alveolar process, where the cribriform and cortical plates meet, is the alveolar margin. The alveolar margin is typically 1–2 mm apical to the cemento-enamel junction so that there is a band of root cementum residing coronal to the alveolus.11,14–16
What is processus alveolaris?
Alveolar process a.k.a. processus alveolaris protrudes from the inferior surface of the body of the bone under the plane of the palatal process. Alveolar process creates a curved shape, with the alveolar arch, its equivalent of the opposite side, in which the roots of the teeth of the maxilla are rooted within sockets or alveoli.
What is the difference between the alveolar and mandible processes?
On the maxilla, the alveolar process is a ridge on the inferior surface, and on the mandible it is a ridge on the superior surface.
What is an alveolar ridge X-ray?
X-rays can be used to view a damaged alveolar process. The alveolar ridge, sometimes referred as the alveolar margin or process, is a modestly raised prominence of both the upper and lower jaw bones located just behind the teeth in human beings.
