a) Avulsion – tooth completely removed from alveolus, luxation – tooth still has contact with the alveolus.
Luxation can be into the alveolar socket (intrusive luxation), out of the alveolar socket (extrusive luxation), or laterally.
The latter is the most common presentation seen..
Luxation is the loosening of the tooth in the socket by progressive severing of the periodontal ligament fibres.
A Couplands elevator of the appropriate size, or a similar instrument is used.
The elevator is inserted behind the gingiva at an acute angle to the tooth root until it hits crestal bone..
Luxation injuries may be classified as concussion, subluxation, intrusion, extrusion, lateral luxation, or avulsion injuries..
A joint luxation is a dislocation or complete separation between the bones that normally articulate (move back and forth) to form a joint.
Subluxation refers to a partial separation of the joint..
If you have pain when chewing, your dentist may splint your luxated tooth to the surrounding teeth to help stabilize the tooth.
Your dentist will regularly monitor your tooth with X-rays and exams.
They will check the condition of your pulp for at least a year.
Extrusive luxation:
Symptoms may include:
Immediate care is often required to prevent complications or tooth loss.
Tooth luxation refers to the displacement of a tooth from its original position in the socket.
Unlike avulsion, where the tooth is completely knocked out of the socket, luxation involves a partial displacement.
Tooth luxation is the dislodgement of a tooth, sometimes invisibly, from an injury to the ligaments and tissues holding the tooth in place.
