What is the alveolar process?

The alveolar process, also called the alveolar bone, includes the thick ridge of bone containing the sockets of the tooth on the jaw bones which hold the teeth. The bones which contain teeth are the maxilla and the mandible. The curved portion of each alveolar process on the jaw is referred to as the alveolar arch.

What is the alveolar bone function?

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. 1.149).

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. The alveolar bone proper is hard, compact bone and not soft, spongy bone.

How alveolar bone is 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.

How is mineralized alveolar bone?

As in cellular cementum, Sharpey fibers in bone are generally mineralized only partially at their periphery. The alveolar crest is the most cervical rim of the alveolar bone proper. In a healthy situation, the alveolar crest is slightly apical to the cementoenamel junction (CEJ) by approximately 1.5 to 2 mm.

What happens to alveolar bone after extraction?

Most of the bone loss occurs during the first six months after the procedure. Afterward, the resorption rate increases at a pace of 0.5–1% on average annually [3,6,7]. Moreover, an estimated 50% of the alveolar bone width is lost within 12 months after the extraction, 30% of which occurs within the first 12 weeks.

What does alveolar mean?

Alveolar: Pertaining to the alveoli, the tiny air sacs in the lungs. The exchange of oxygen and carbon dioxide takes place in the alveoli which look like cells in a honeycomb. The word comes from the Latin diminutive of “alveus” meaning a cavity or hollow = a little cavity or hollow.

Which bone has alveolar process?

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.

What is the alveolar margin?

Periodontium. 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.

How is alveolar bone removed?

About the Surgery Bone is typically taken from the iliac crest (hip bone). The surgeon makes a small incision in the hip area, then removes some of the spongy bone from the inside of the hip bone. Incisions are then made in the gums at the cleft site, and the spongy bone is placed into the alveolar cleft.

What is alveolar and give the examples?

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.

What is the alveolar process and what does it do?

The alveolar process is the thick ridge of bone in the jaw that holds the dental alveoli, or tooth sockets. The dental alveoli hold the roots of the teeth in place, and in case of a dental implant, the alveolar process holds implant hardware in place.

What kind of bone is the alveolar bone made of?

Your alveolar process (also known as the alveolar bone) is the structure that holds the roots of your teeth in place. You have an alveolar process made of thick bone for both your top and bottom rows of teeth.

What happens to the alveolar bone with loss of a tooth?

Alveolar bone(process) Alveolar process is defined as the parts of the maxilla and mandible that form and support the tooth sockets. Forms with eruption of tooth to provide osseous attachment to forming pdl. Disappears with loss of tooth Because the alveolar processes develop and undergo remodeling with tooth

How are the alveoli related to the dental roots?

In adults, the inferior surface of the alveolar process has the inlets for eight alveoli which are divided from one another by interalveolar septa. The shape of the alveoli corresponds to the embedded dental roots: The alveoli for the incisors end in a convex bony margin corresponding to the concave enamel borders of the homonymous teeth.
