Abstract:

BACKGROUND: Because of good performance, beautiful and permanent color, and certain compressive strength, light-cured composite resin has been widely used in dental restoration. But there are less reports about its usage in adult crown restoration during orthodontic treatment.

OBJECTIVE: To explore the feasibility of light-cured composite resin in the adult crown restoration during orthodontic treatment.
METHODS: 300 adult cases of crown defects scheduled for orthodontic treatment were enrolled, including 160 males and 140 females, aged from 16 to 41 years. All the crown defects were filled with light-cured composite resins. After 36-month follow-up, the gross appearances of repaired teeth, repairing effect and adverse reactions were statistically recorded and analyzed.

RESULTS AND CONCLUSION: After restoration, patients exhibited normal occlusion, and the filled crowns were fixed stably and firmly whose appearance was symmetric with that of the contralateral isonym tooth of the adjacent tooth. In addition, patients complained of no percussion pain, and no apical shade was shown by X-ray examination. At the end of the follow-up, crown restoration was successful in 268 of 300 cases, with a success rate of 89.33%, and the filled crowns fell out in the other 32 cases; 271 of 300 cases were satisfied with the repairing effect, and the satisfaction rate was 90.33%. Besides, there were no serious adverse reactions in all the patients. These results show that light-cured composite resin for adult crown restoration during orthodontic treatment obtains a higher repair success rate and satisfaction rate, with no serious adverse reactions.
