Abstract

OBJECTIVE: To observe the clinical effect on the treatment of traumatic intrusion of upper anterior teeth using orthodontic extrusion combined with fixation. METHODS: 24 cases, 27 teeth included, were treated by means of orthodontic extrusion combined with composite-resin split fixation. The clinical effect of 2-year-period was recorded. RESULTS: After the treatment of 27 selected teeth (16 immature teeth,11 mature teeth),11 teeth achieved the standard of success,16 teeth achieved the standard of efficiency, none of them was failing. CONCLUSION: Orthodontic extrusion combined with composite-resin split fixation is an active and atraumatic method in the treatment of traumatic intrusion of upper anterior teeth, and the effect is ideal.
