This study aims to compare the impact of titanium and stainless steel (SS) retainer wires on lower incisor stability and periodontal health.
Fifty patients between the ages of 14.1 and 29.5 years were recruited for the study. The impact of 0.027x0.011-inch rectangular titanium dead-soft wire retainers was compared with that of 0.0215-inch six-stranded SS wire retainers. The retainers were bonded to the mandibular arch, and 3D models were evaluated after completion of the orthodontic treatment (T1), at the third month (T2), and at the sixth month (T3). Little's irregularity index (LII), the intercanine width, the pocket depth, the plaque index, bleeding on probing, and retainer survival were analyzed. The generalized linear model method was used to compare scores on LII, the intercanine width, the pocket depth, and plaque index values. Cochran's Q test was used to compare intragroup bleeding.
A significant increase was found in the irregularity index parameter according to time (p=0.004) but no statistically significant difference was found between groups in terms of the LII according to material and time (p=0.826). No significant difference was found in intercanine width parameters between the groups according to material and time (p=0.977). No statistically significant difference was found between the groups in terms of pocket depth and plaque index scores, according to material and time. No retainer failure was observed in either group.
Both retainer wires offer successful results in terms of stability parameters and periodontal parameters after six months.
本研究旨在比较钛丝和不锈钢（SS）保持丝对下前牙稳定性和牙周健康的影响。
招募了50名年龄在14.1至29.5岁之间的患者进行该研究。将0.027×0.011英寸的矩形钛超软丝保持器的影响与0.0215英寸的六股SS丝保持器的影响进行比较。将保持器粘结到下颌牙弓上，并在正畸治疗完成后（T1）、第三个月（T2）和第六个月（T3）对三维模型进行评估。分析了Little不规则指数（LII）、尖牙间宽度、牙周袋深度、菌斑指数、探诊出血和保持器存留情况。采用广义线性模型方法比较LII、尖牙间宽度、牙周袋深度和菌斑指数值的得分。采用Cochran's Q检验比较组内出血情况。
根据时间，不规则指数参数有显著增加（p = 0.004），但根据材料和时间，两组在LII方面无统计学显著差异（p = 0.826）。根据材料和时间，两组在尖牙间宽度参数方面无显著差异（p = 0.977）。根据材料和时间，两组在牙周袋深度和菌斑指数得分方面无统计学显著差异。两组均未观察到保持器失败。
六个月后，两种保持丝在稳定性参数和牙周参数方面均取得了成功的结果。
