Alveolar bone
Alveolar bone (pronunciation: al-vee-uh-lar bone) is a specialized part of the jawbone that forms the bony socket for teeth. It is a critical component of the dental anatomy and plays a significant role in both dental health and procedures such as dental implants.
Etymology
The term "alveolar" is derived from the Latin word "alveolus" meaning "small cavity". This is a reference to the small cavities, or sockets, in the alveolar bone that house the teeth.
Structure
The alveolar bone is composed of two parts: the alveolar bone proper, also known as the cribriform plate, and the supporting alveolar bone. The alveolar bone proper is the thin, compact bone that forms the tooth socket and is perforated by many small holes for the passage of blood vessels and nerves. The supporting alveolar bone consists of both compact and spongy bone and provides support to the alveolar bone proper.
Function
The primary function of the alveolar bone is to support teeth and keep them in place. It also plays a role in the transmission of forces produced during chewing from the teeth to the rest of the skull. The health of the alveolar bone is crucial for maintaining dental health and for the success of procedures such as dental implants.
