Abstract
The general prognosis of luxational tooth injury and recommendations for treatment are described based on the guideline for management of acute dental trauma which was established by the Japan Association for Dental Traumatology in 2012. The most important points for dentists when starting to consider prosthodontic treatment for a tooth affected by luxational injury are healing of damaged periodontal tissues and prevention and/or treatment of external root resorption. It is not difficult to optimize healing of periodontal tissues. However, the condition and timing at which to start considering prosthodontic treatment for the affected tooth with luxational injury such as intrusion or avulsion are not clear because the pathogenesis of external root resorption has not been elucidated yet. Therefore, prosthodontic treatment can be considered based on informed choice of the patient after he/she is informed of the risk to the outer root resorption of the tooth affected by luxational injury.
