title: [Clinical retrospect on autoimplantation of traumatically dislocated teeth].
abstract: OBJECTIVE
  A total of 48 cases with autoimplantation of traumatically dislocated teeth were retro spected as clinical references.
  
  
  METHODS
  Several indexes were recorded in details, for instance, tooth dislocation time, operation and postoperative management and patients were followed up periodically.
  
  
  RESULTS
  Tooth dislocating intervals from trauma to implantation were from 0.5 to 48 hours. Therapeutic effectiveness was graded as perfect in 37 teeth (61.7%), good in 18 (30.0%) and poor in 5 teeth (8.3%), in which 3 teeth were extracted within 1 year. Three-year success rate was 83.0%, and five-year success rate was 61.7%. It was judged 20 teeth being as periodontal membranous healing, 35 bony healing and 5 fibrous healing. Pulpal vitality tests were positive in 23 and negative in 37 teeth. Root canal therapies were conducted in 20 teeth.
  
  
  CONCLUSIONS
  Carefully protecting periodontal membranes, keeping good fixation, preventing from infection and avoiding occlusal injuries are important factors for successful implantation of the dislocated teeth. Periodical examination would be benefit to the long term prognosis. The correct methods for dislocated tooth preservation should be treated as the important part of health education.
