Objective: To study the therapeutic effects of orthodontic-repair combined therapy on the correction of single incisors in adult anterior teeth. Methods: 24 cases were selected according to certain criteria. To achieve the best aesthetic effect, enamel was removed through the adjacent surface to relieve crowding. An orthodontic appliance was used to lift the single tooth of the anterior teeth and repaired with a ceramic crown . After 6 months to 3 years of follow-up, investigate the appearance of prosthesis, gum health, patient satisfaction and so on. Results: After investigation, in 24 clinical cases, the orthodontic and repair treatments were carried out according to the above design. The finished porcelain crowns were successfully put in place. All cases were lifted anti-, was shallow , shallow cover, reached the aesthetic and functional requirements of the anterior teeth, retention is good. According to the revised standard of American Public Health Association, follow-up ranged from 6 months to 3 years, reaching 100% grade A within 3 years follow-up; 95% follow-up 3 years to reach grade A; Follow-up 3 years food impaction A grade can reach 97%. CONCLUSION: The orthodontic-repair combination therapy used in this study has obvious therapeutic effect on the single tooth reflex in adult anterior teeth, which can make up for the deficiencies caused by single orthodontic or repair treatment and achieve satisfactory therapeutic effect.
