Long-term retention with fixed retainers with a high success rate seems to be a reasonable solution to minimize or prohibit relapse of orthodontic treatment. Two hundred sixty patients between 13 and 30 years old were recruited for this study. The 0.0175 stainless steel twisted wire (G&H Orthodontics, USA) was compared with a single-strand ribbon titanium lingual retainer wire (Retainium, Reliance orthodontics, USA) was used. When treatment was completed, the retainers were bonded from canine to canine in the mandibular arch of the participants. In the follow-up visits, the patients were recalled every 3 months during the 24 months. Detachments, the time of debonding, and side effects were recorded. Statistical analysis was performed by a blinded statistician using a statistical package for Social Science (SPSS, Version20). After descriptive statistics, Kaplan-Meier analysis was performed to measure the survival rates of each retainer. P value < 0.05 was considered as significant. Finally, 138 patients who received twisted wire splint and 112 patients who received ribbon wire were included in the analysis. The average duration of success was about 23 months for twisted wire and ribbon wire, according to the Kaplan-Meier estimates. The analysis showed no significant overall difference between the treatments (p = 0.13). Failure rates in terms of detachments in all groups occurred at the enamel junction, and it was 25 in twisted retainer group (18.1%) and was 10 in ribbon retainer group (8.9%); the Kaplan-Meier analysis test detected a significant difference in the failure rates between the groups (p = 0/006). Although the conventional twisted stainless steel wire and single-strand titanium flat metal ribbon wire as fixed orthodontic retainers have the same clinical effects, it was shown that the ribbon wire has less failure in terms of detachments.

用于舌固定固定器的多股钢丝和单股带状钢丝的临床比较。

使用固定保持器以高成功率长期保留似乎是减少或禁止正畸治疗复发的合理解决方案。本研究招募了160名年龄在13至30岁之间的患者。将0.0175不锈钢双绞线（美国G＆H Orthodontics）与单股带状钛钛舌固定线（Retainium，Reliance Orthodontics，美国）进行了比较。治疗完成后，将固定器从参与者的下颌弓中的各个犬类粘合在一起。在随访中，患者在24个月中每3个月被召回一次。记录剥离，剥离时间和副作用。盲人统计学家使用社会科学统计软件包（SPSS，版本20）进行统计分析。经过描述性统计后，进行Kaplan-Meier分析以测量每个固定器的存活率。P值＜0.05被认为是显着的。最后，将138例接受双绞线夹板的患者和112例接受带状钢丝的患者纳入分析。根据Kaplan-Meier的估计，双绞线和带状线的平均成功时间约为23个月。分析显示治疗之间没有显着的总体差异（p = 0.13）。所有组的剥离失败率均发生在牙釉质连接处，扭位固定器组为25（18.1％），色带固定器组为10（8.9％）。Kaplan-Meier分析测试发现两组之间的失败率存在显着差异（p = 0/006）。
