Socket preservation or alveolar ridge preservation (ARP) [1] 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) [ 2 ] membrane containing bone growth enhancing elements can be stitched over the wound or a graft material or scaffold is placed ...
The alveolar process is also called the alveolar bone or alveolar ridge. [3] In phonetics , the term refers more specifically to the ridges on the inside of the mouth which can be felt with the tongue , either on roof of the mouth between the upper teeth and the hard palate or on the bottom of the mouth behind the lower teeth.
The PDL also undergoes drastic changes with chronic periodontal disease that involves the deeper structures of the periodontium with periodontitis. The fibers of the PDL become disorganized, and their attachments to either the alveolar bone proper or cementum through Sharpey fibers are lost because of the resorption of these two hard dental tissue.
"The oral region comprises 1% of the total body area, yet it accounts for 5% of all bodily injuries. In preschool children, oral injuries make up as much as 17% of all bodily injuries. The incidence of traumatic dental injuries is 1–3%, and the prevalence is steady at 20–30%." [49]
Dental abscess; Other names: Dentoalveolar abscess, Periapical abscess, tooth abscess, root abscess: A decayed, broken down tooth, which has undergone pulpal necrosis.A periapical abscess (i.e. around the apex of the tooth root) has then formed and pus is draining into the mouth via an intraoral sinus ().
[1] [page needed] In French, the contact that is the farthest back is alveolar or sometimes slightly pre-alveolar. In Spanish, /t/ and /d/ are laminal denti-alveolar, [2] and /l/ and /n/ are alveolar but assimilate to a following /t/ or /d/. Similarly, in Italian, /t/, /d/, /t͡s/, /d͡z/ are denti-alveolar, and /l/ and /n/ are alveolar. [3]
Tooth development begins at week 6 in utero, in the oral epithelium. The process is divided into three stages: Initiation; Morphogenesis and; Histogenesis [2]; At the end of week 7 i.u., localised proliferations of cells in the dental laminae form round and oval swellings known as tooth buds, which will eventually develop into mesenchymal cells and surround the enamel organ.
Division 1 – the upper central incisors are proclined or of average inclination and there is an increase in overjet; Division 2 – The upper central incisors are retroclined. The overjet is usually minimal or may be increased. Class III: The lower incisor edges lie anterior to the cingulum plateau of the upper incisors.
