Traumatic dislocation of the permanent anterior teeth

[ad_1]

Permanent anterior teeth due to trauma may lead to partial or complete dislocation. Dislocation by the external impact is the most common cause of tooth, teeth previously more common. Part of post-traumatic prolapse teeth tooth socket, clear stretch, known as the tooth part of the prolapse. It is as follows: tooth displacement, deviation from the long axis of the original tooth, teeth may stretch, with the teeth with occlusal trauma, loose teeth, or loose is not obvious. Periodontal Dental Instruments ligament, pulp and alveolar bone may be associated with injury, such as periodontal ligament tear, rupture of blood vessels and nerves, often accompanied by incomplete enamel broken. Dental alveolar bone by the external force as the teeth fully complete prolapse prolapse. This dislocation is common in single young permanent teeth. The main reason is: the young root development of permanent teeth has not been completed, the periodontal ligament flexibility, the horizontal force easily lead to tooth complete prolapse.

Dislocation can occur after dental complications:

(1) pulp hemorrhage: traumatic dental pulp can cause varying degrees of bleeding, can usually return to normal, younger patients recover faster.

(2) pulp necrosis: incidence of pulp necrosis accounted for 52% of tooth dislocation, than the development of mature teeth more susceptible to immature young permanent pulp necrosis.

(3) outside the root absorption: the most common in embedded dislocation, about 2% of patients with teeth in absorption.

(4) canal narrowing or disappearance: dislocation of the complications accounted for 20% of teeth to 50%, crown color darkens, unresponsive or lost pulp vitality.

(5) alveolar absorption edge: with obvious dislocation, the occurrence of marginal alveolar absorption probability. If not reset, periodontal tissue damage will increase.

Post-traumatic dislocation of the tooth, should What is the overdenture be neutered as soon as possible to the hospital or the implementation of a fixed tooth replantation. Replanted within one hour after injury, the higher the survival rate of teeth. Teeth fixed, you can restore occlusion, but also to reduce the displacement of teeth, dental bleeding, and pain and is conducive to the restoration of tooth trauma. Trauma dental bite through the transfer of fixed, may reduce the incidence of pulp necrosis, followed by the prevention of tooth discoloration and maintain the beauty of the teeth, which is very important for young permanent teeth.
