摘要： 目的：探讨3D打印树脂夹板和Hawley保持器联合舌侧保持丝对牙周病患者正畸疗效保持效果的差异。方法：选择2021年1月—2022年2月牙周病正畸治疗结束的患者40例,根据随机数表法分为试验组和对照组,每组各20例。试验组采用3D打印树脂夹板保持器;对照组采用Hawley保持器联合舌侧保持丝保持。记录2组椅旁操作时间,正畸治疗结束后1个月和6个月时,分别测量2组患者上、下颌尖牙宽度,磨牙宽度,覆、覆盖及Little 指数。采用SPSS 12.0软件包对数据进行统计学分析。结果：试验组和对照组椅旁操作平均时间分别为8.23、11.17 min。2组保持器戴入1个月和6个月后,上、下颌尖牙宽度,磨牙宽度,覆、覆盖及Little 指数有统计学差异（P<0.05）,6个月时试验组显著大于对照组（P<0.05）。结论：3D打印树脂夹板的椅旁操作时间短,保持效果优于Hawley保持器联合舌侧保持丝,其他方面两者疗效基本一致。

Abstract: PURPOSE: To investigate the difference in the retention effect of 3D printing resin splint and Hawley retainer combined with lingual retention wire in periodontal disease patients after orthodontic treatment. METHODS: Forty patients who finished orthodontic treatment for periodontal disease from January 2021 to February 2022 were selected and divided into experimental group and control group according to the random number table method, with 20 patients in each group. Patients in the experimental group used 3D printing resin splint for retention, while patients in the control group used Hawley retainer combined with a lingual retention wire for retention. The chair-side operation time of the retainers was recorded for both groups. The maxillary and mandibular cuspid width, molar width, overjet, overbite and irregularity index were measured at 1 month and 6 months after orthodontic treatment in both groups. Statistical analysis was performed with SPSS 12.0 software package. RESULTS: The mean time for chair-side manipulation of experimental group and control group was 8.23, 11.17 min, respectively. The difference between the two groups was statistically significant (P<0.05) when comparing the width of the maxillary and mandibular cusps, the width of the molars, overjet, overbite and the irregularity index after 1 month and 6 months of wear of the retainers, which were significantly greater in the experimental group than in the control group at 6 months(P<0.05). CONCLUSIONS: 3D printing resin splint, with short chair-side manipulation time, was more effective than Hawley retainer combined with a lingual retention wire, and the efficacy of both groups was otherwise generally consistent.
