An analysis of 58 traumatically intruded and surgically extruded permanent teeth.
Fifty-eight traumatically intruded and mainly surgically extruded permanent teeth were followed up for 3 years and 4 months (mid-term results: 29 teeth) and 9 months (short-term results: 29 teeth) on average. Statistically, the mid-term results showed more cases of severe crown discoloration (54%) than the short-term results (9%), but no difference in pulpal and periodontal healing. Three teeth (5%) were lost. Factors which positively influenced pulpal healing were shallow intrusion depth, intact crown and immaturity of the root. Factors which positively influenced periodontal healing were shallow intrusion depth and minimal surgical manipulation. Alveolar bone healing was positively influenced only by shallow intrusion depth.
