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. Conclusion: Carefully protecting periodontal membranes, keeping good fixation, preventing from infection and avoiding occlusal injuries are important factors for successful implantation of the dislocated teeth.
