Complete dislocation of the tooth
03-09-2009
At full dislocation is a complete rupture of the tissues of the tooth and a circular bundle. This is accompanied by precipitation of a tooth from the alveolus under the applied force or its own weight. Neurovascular bundle is torn, can be determined by fracture edge alveoli, dislocated tooth. Sometimes the tooth is retained in the alveoli as a result of adhesive properties of the two wet surfaces. Often dislocating frontal teeth of the upper jaw, at least - the bottom. Central incisors dislocate more often than the side. Less prone to complete dislocation of other canines.
Luxated tooth patients sometimes bring a doctor. Most common complaints of pain in the hole of the missing tooth. Medical history without singularities: a blow to the teeth, falling, etc. The external examination of the changes are more pronounced than in incomplete dislocation, because of the impact of greater strength. Hole dislocated tooth immediately after the injury is bleeding, after a while running a blood clot. The mucous membrane of the gums sometimes broken, that is more common in the fracture edge of the alveoli dislocated tooth. Palpation of its painful. Survey walls of the hole required, as the subsequent treatment (replantation) dislocated tooth will give positive results only, while maintaining the integrity of bone structures of the hole.
At X-ray determined free from tooth alveolus with clear contours. Possible violation of the integrity of the compact inner layer, and sometimes the spongy substance on a particular section of the wall holes or edges.

A partial dislocation is characterized by rupture of the periodontal fibers. Unexploded fibers, usually spread over a greater or lesser extent.
Incomplete dislocation often Esego changing situation in the dental crown of the tooth row and the root relative to the walls of the alveoli. Depending on the direction of space applications and the gravity of the tooth may shift toward the occlusal plane, the adjacent tooth and a lip or oral side, to turn around the axis. All this leads to the violation forms dentition.

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.
