Dental alveolus
Dental alveoli (singular ''alveolus'') are sockets in the jaws in which the roots of teeth are held in the alveolar process of maxilla 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 ''gomphosis'' (plural ''gomphoses'').Alveolar bone is the bone that surrounds the roots of the teeth forming bone sockets a.k.a. alveolus.
In mammals, tooth sockets are found in the maxilla, the premaxilla and the mandible.
==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 at the time of〔(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 sutured.〔(Extraction socket preservation: The time is now )〕
