| 目的探讨直丝弓矫治器和Invisalign矫治器在拔牙患者排齐阶段的支抗需求及其应用效果。 方法选择需拔除4个前磨牙的双颌前突正畸患者100例,随机均分为对照组(直丝弓矫治器)和观察组(Invisalign矫治器)。比较两组矫治效果、正畸时间、牙周健康情况[牙龈指数、菌斑指数(PLI)、牙龈沟出血指数、牙龈沟探测深度及临床附着丧失程度]及支抗需求(牙齿移动速度、非期望牙齿移动率)。 结果观察组总有效率、牙齿移动速度、VAS评分低于对照组,矫正时间长于对照组,非期望牙齿移动率、美观总满意度高于对照组(P＜0.05)。与矫治前比较,矫治后对照组各牙周指标均升高,观察组PLI升高；且矫治后观察组各牙周指标均低于对照组(P＜0.05)。 结论与直丝弓矫治器相比,Invisalign矫治器佩戴美观,在牙周健康和疼痛方面表现更佳,但其支抗需求、矫治效果相对较弱,且治疗时间更长。 |

| AimTo investigate the anchorage requirements and clinical efficacy of straight wire appliance (SWA) and Invisalign in the alignment stage of extraction patients. MethodsA total of 100 patients with bimaxillary protrusion requiring extraction of four premolars were randomly divided into control group (SWA) and observation group (Invisalign), with 50 cases in each group. The treatment efficacy, orthodontic duration, periodontal health indicators [gingival index (GI), plaque index (PLI), sulcus bleeding index (SBI), probing depth (PD), and clinical attachment loss (CAL)], and anchorage requirements (tooth movement rate and undesired tooth movement rate) were compared between the two groups. ResultsThe observation group showed lower total efficacy, tooth movement rate, and visual analog scale (VAS) scores, but longer treatment duration and higher undesired tooth movement rate and aesthetic satisfaction compared to the control group (P＜0.05). Compared with pre-treatment, all periodontal indicators increased in the control group, while only PLI increased in the observation group. Post-treatment periodontal indicators in the observation group were lower than those in the control group (P＜0.05). ConclusionCompared with SWA, Invisalign offers better aesthetics, periodontal health, and pain control, but requires higher anchorage, exhibits weaker treatment efficacy, and has a longer treatment duration. |
