What is the function of the alveolar process?
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.
Why is it called alveolar?
Terminology. The term alveolar (/ælˈviːələr/) (‘hollow’) refers to the cavities of the tooth sockets, known as dental alveoli. The alveolar process is also called the alveolar bone or alveolar ridge. The curved portion is referred to as the alveolar arch.
What is the alveolar process composed of?
compact bone
The alveolar process is the lining of the tooth’s socket and referred to as the alveolus. Although the alveolar process is made up of compact bone, it may also be called the cribriform plate as it contains various holes where Volkmann canals pass from the alveolar bone and into the PDL.
What is the highest point of the alveolar process?

- alveolar crest. highest point of the alveolar ridge.
- alveolar socket. cavity within the alveolar process that surrounds the root of a tooth.
- ameloblasts. cells that form enamel.
- anatomic crown. portion of the tooth that is covered with enamel.

- cementoclasts.
When is alveolar bone formed?
Alveolar bone/ Alveolar process Is the portion of maxilla and mandible that forms and supports the tooth socket (alveoli). It forms when tooth erupts to provide the osseous attachment to the forming PDL; It disappears gradually after tooth is lost.
What is an alveolar?
Medical Definition of alveolar 1 : of, relating to, resembling, or having alveoli. 2 : of, relating to, or constituting the part of the jaws where the teeth arise, the air-containing cells of the lungs, or glands with secretory cells about a central space. More from Merriam-Webster on alveolar.
What are the parts 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. Radiographically, this appears as a fine radiodense line called the lamina dura.
What is alveolar and example?

What is the other name for alveolar?
A pulmonary alveolus (plural: alveoli, from Latin alveolus, “little cavity”), also known as an air sac or air space, is one of millions of hollow, distensible cup-shaped cavities in the lungs where oxygen is exchanged for carbon dioxide.
What causes fenestration?
A naturally occurring fenestration leaves the exposed root surface in direct contact with either the alveolar mucosa or the gingiva. The condition may be caused by a variety of factors including tooth movement due to orthodontics, pathology (both endodontic and periodontal), root apex contours, and occlusal issues.
What is the crest of alveolar bone?
The alveolar crest is the most coronal portion, or the top, of the alveolar process. It is an extension of both the mandible and maxilla and holds the tooth sockets. The alveolar crest is often the first portion of the alveolar process that is damaged by periodontal disease and is therefore the first bone that is lost.
What is called fenestration?
Definition of fenestration 1 : the arrangement, proportioning, and design of windows and doors in a building. 2 : an opening in a surface (such as a wall or membrane) 3 : the operation of cutting an opening in the bony labyrinth between the inner ear and tympanum to replace natural fenestrae that are not functional.
