Dental alveoli (singular alveolus) are sockets in the jaws 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 ...
After extraction of a tooth, the clot in the alveolus fills in with immature bone, which later is remodeled into mature secondary bone. Disturbance of the blood clot can cause alveolar osteitis, commonly referred to as "dry socket". With the partial or total loss of teeth, the alveolar process undergoes resorption.
Dental trauma, such as subluxation, may cause tearing of the PDL and pain during function (eating). [12] The PDL cells of an avulsed tooth are at risk of drying and desiccation if left in dry storage. Wet storage in an isotonic liquid, although a superior method to dry storage, can preserve PDL vitality depending on the medium but not for an ...
They then enter the alveolar canals on the infratemporal surface of the maxilla, and, passing from behind forward in the substance of the bone, communicate with the middle superior alveolar nerve, and give off branches to the lining membrane of the maxillary sinus and gingival and dental branches to each molar tooth from a superior dental ...
Periodontics is the dental specialty that relates specifically to the care and maintenance of these tissues. It provides the support necessary to maintain teeth in function. It consists of four principal components, namely: [1] Gingiva (the gums) Periodontal ligament (PDL) Cementum; Alveolar bone proper
The risk of nerve injury in relation to mandibular dental implants is not known but it is a recognised risk requiring the patient to be warned. [10] If an injury occurs urgent treatment is required. The risk nerve injury in relation deep dental injections has a risk of injury in approximately 1:14,000 with 25% of these remaining persistent.
Vessels and nerves: :25. dental :26. periodontal :27. alveolar through channel In dental anatomy, the apical foramen , literally translated "small opening of the apex," is the tooth's natural opening, found at the root's very tip—that is, the root apex — whereby an artery, vein, and nerve enter the tooth and commingle with the tooth's ...
Diagram of tooth anatomy. Dental anatomy is a field of anatomy dedicated to the study of human tooth structures. The development, appearance, and classification of teeth fall within its purview. (The function of teeth as they contact one another falls elsewhere, under dental occlusion.)
