目的研究自锁矫治与传统矫治体系治疗错畸形的初始疼痛及溃疡发生情况。方法将错畸形患者纳入研究,随机分为给予自锁矫治体系治疗的观察组和给予传统矫治体系治疗的对照组,观察治疗后的疼痛程度及溃疡发生例数。结果 (1)治疗后1、3、5及7d时,观察组的NRS评分低于对照组,差异有统计学意义(P<0.05);(2)治疗后7d内,观察组患者发生溃疡的例数少于对照组,差异有统计学意义(P<0.05)。结论自锁矫治体系有助于缓解疼痛、控制溃疡,在错畸形的治疗中具有积极价值。
Objective To study the initial pain and the occurrence of ulcer with self-locking orthodontic treatment and traditional orthodontic treatment. Methods The patients with malformations were included in the study and were randomly divided into observation group treated with self-locking treatment system and control group treated with traditional orthodontic treatment system. The degree of pain after treatment and the number of cases of ulcer were observed. Results (1) At 1, 3, 5 and 7 days after treatment, the NRS score of the observation group was lower than that of the control group (P <0.05). (2) Within 7 days after treatment, the ulcer The number of cases was less than the control group, the difference was statistically significant (P <0.05). Conclusion Self-locking correction system can help relieve pain and control ulcer and has positive value in the treatment of malformation.
