When incomplete dislocation of the tooth under conduction anesthesia should be carefully reponirovat it. At the same time his fingers have not only dislocated the tooth, but necessarily on neighboring and alveolar bone. It is necessary to prevent accidental breakdowns it in the opposite direction. The pressure on the tooth should be developed gradually and moderately, to not further damage the neurovascular bundle at the site of its entry in the apical hole. Proper conduct of repositioning can be defined by the absence of contact with the antagonist only reponiruemogo of the tooth.

When dislocation occurs dive impacted tooth root into the bone of the alveolar process and body of the mandible and a partial or complete displacement of tooth crown in the alveoli, which is possible when struck on the cutting edge of the tooth. Impacted dislocation often accompanied by a complete rupture of periodontal fibers. Neurovascular bundle, as a rule is broken. Due to the introduction of a wide part of the tooth into a narrow part of the alveolus bone ravine its walls are deformed, compressed and break down.

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.

 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.
