目的 分析三维数字化牙𬌗模型进行成人口腔正畸无托槽隐形矫治过程中牙根移动效率与精准度。方法 选取2023-02至2025-02于空军特色医学中心进行口腔正畸治疗的患者86例,随机分为对照组与试验组,每组43例。对照组予传统无托槽隐形矫治方式,试验组予三维数字化无托槽隐形矫治方式。于治疗前后检测两组牙周指标,包括牙龈指数(GI)、龈沟探诊深度(SPD)、龈沟出血指数(SBI)、菌斑指数(PLI),咬合功能指标(咬合力、咀嚼功能评分),龈沟液中炎症因子(IL-1β、IL-6、TNF-α)及氧化应激指标(SOD、MDA、ROS),记录牙根移动率、精准度情况。结果 试验组牙周指标:GI(0.66±0.31)vs.(0.90±0.21)、SBI(0.15±0.07)vs.(0.46±0.25)、PLI(1.09±0.69)vs.(2.12±0.85)均低于对照组,SPD(3.18±1.22)mm vs.(2.59±1.13)mm高于对照组;炎症及氧化应激水平:IL-1β、IL-6、TNF-α、MDA、ROS 均低于对照组,差异有统计学意义(P＜0.05);三维精度:牙冠顶部、根尖部及牙根深度偏差分别减少 19.2%、18.6%、20.0%,角度偏差降低 19.6%;功能恢复:咬合力提高 22.9%,咀嚼功能评分提升 29.1%;抗氧化能力:SOD 活性增加 25.8%。牙根移动效率呈现明显方向差异:近远中向(46.4%)＞颊向(50.0%)＞压低向(40.3%)＞舌向(38.8%)＞颊舌向(37.5%)＞伸长向(27.7%)。结论 三维数字化能够有效提升成人口腔正畸无托槽隐形矫治过程中牙根移动效率与精准度,具有临床应用价值。
Abstract
Objective To analyze the efficiency and accuracy of tooth root movement during invisible bracketless orthodontic treatment for adults using three-dimensional (3d) digital technique. Methods A total of 86 patients who received orthodontic treatment at Characteristics Medical Center Affiliated to Military Medical University of PLA Air Force from February 2023 to February 2025 were selected and randomly divided into a control group and an experimental group, with 43 patients in each group. The control group received traditional invisible bracketless orthodontic treatment, while the experimental group received the traditional treatment combined with 3d digital technique. Before and after the treatment, periodontal indicators (GI, SBI, PLI, SPD), occlusal function indicators [bite force, chewing function score], inflammatory factors in gingival crevicular fluid (IL-1β, IL-6, TNF-α), oxidative stress indicators (SOD, MDA, ROS), and root movement rate and accuracy were recorded. Results Periodontal indicators of the experimental group: GI (0.66±0.31) vs. (0.90±0.21), SBI (0.15±0.07) vs. (0.46±0.25), PLI (1.09±0.69) vs. (2.12±0.85) were all lower than those of the control group, and SPD (3.18±1.22) mm vs. (2.59±1.13) mm was higher than that of the control group. Inflammatory and Oxidative Stress Levels: IL-1β,IL-6,TNF-α,MDA, and ROS were all lower than those of the control group, and the differences were statistically significant (P<0.05). Three-dimensional accuracy: deviations at crown top, root tip, and root depth decreased by 19.2%, 18.6%, and 20.0%, respectively, with angular deviation reduced by 19.6%.Functional recovery: bite force increased by 22.9%, and chewing function score improved by 29.1%. Antioxidant capacity: SOD activity rose by 25.8%. There was a significant directional difference in tooth root movement efficiency: mesiodistal(46.4%), buccal (50.0%), depressional (40.3%), lingual (38.8%), buccolingual (37.5%), and elongational (27.7%). mesiodistal (46.4%), buccal (50.0%), depressional (40.3%), lingual (38.8%), buccolingual (37.5%), and elongational (27.7%). Conclusions Three-dimensional digital technique can effectively improve the efficiency and accuracy of tooth root movement in the process of adult orthodontic invisible bracketless orthodontic treatment, and has clinical application value.
