Dislocation of the tooth

03-09-2009

Damage to the upper jaw, according to the literature, up 64.4%, lower – 22,1%, both jaws simultaneously – 13,5%. Thus, traumatic injuries of the upper jaw there are 3 times more frequently than the teeth of the mandible.

The cause of dislocation of the tooth – the force applied to the crown of the tooth: blow, nibble hard food, getting to the tooth of a foreign body in a lump of chewed food, bad habits (opening beer bottles with his teeth). In case of incorrect or careless use of dental forceps or elevators for the removal of teeth (shtykovidnogo) or roots (direct, angular) can occur dislocation located near a tooth. Due to the applied force the entire tooth moves in a certain direction, which is accompanied by a change in the relationship of the root of the tooth with the walls of the alveoli. Thus there is a partial or complete breakdown of the periodontal fibers, various degrees of damage to the neurovascular bundle of the tooth. Clinically it can manifest partial or complete dislocation of the tooth from the alveoli. It depends on the direction and intensity of the current force, place of its applications, age-structure of bone tissue. There are part-time, full of quirks and impacted teeth. Dislocation can be isolated, accompanied by a fracture of crown or root of the tooth, fractured alveolar bone or jaw.
