Dental alveoli (singular alveolus) are sockets in the in which the roots of teeth are held in the alveolar process with the periodontal ligament. The lay term for dental alveoli is tooth sockets. A joint that connects the roots of the teeth and the alveolus is called a gomphosis (plural gomphoses). Alveolar bone is the bone that surrounds the roots of the teeth forming bone sockets.
In , tooth sockets are found in the maxilla, the premaxilla, and the mandible.
Etymology
1706, "a hollow", especially "the socket of a tooth", from Latin alveolus "a tray, trough, basin; bed of a small river; small hollow or cavity", diminutive of alvus "belly, stomach, paunch, bowels; hold of a ship", from PIE root *aulo- "hole, cavity" (source also of Greek aulos "flute, tube, pipe"; Serbo-Croatian, Polish, Russian ulica "street", originally "narrow opening"; Old Church Slavonic uliji, Lithuanian aulys "beehive" (hollow trunk), Armenian yli "pregnant"). The word was extended in 19c. anatomy to other small pits, sockets, or cells.
Socket preservation
Socket preservation or alveolar ridge preservation (ARP)
is a procedure to reduce bone loss after
tooth extraction to preserve the dental alveolus (tooth socket) in the
alveolar bone. A platelet-rich fibrin (PRF)
membrane containing bone growth enhancing elements can be stitched over the wound or a graft material or scaffold is placed in the socket of an extracted tooth.
[ Tassos Irinakis, Rationale for Socket Preservation after Extraction of a Single-Rooted Tooth when Planning for Future Implant Placement, Journal of Canadian Dental Association 2006; 72(10):917–922] The socket is then directly closed with stitches or covered with a non-resorbable or resorbable membrane and
Surgical suture.
Pathology
The swelling of the dental alveoli can result in
Dry socket, causing pain and discomfort to the mouth.
