| 目的探讨数字化隐形矫治技术治疗成人轻中度骨性Ⅲ类错..畸形的临床效果。方法选取 2019年 8月至 2021年 8月合肥市口腔医院成人轻到中度骨性Ⅲ类错..病人 24例，采用随机数字表法将观察对象分为观察组和对照组，每组各 12例，观察组采用数字化隐形矫治技术，对照组采用固定矫治技术即 MBT矫治技术。测量治疗前后头颅侧位片 16项软硬组织指标，比较两组治疗后软硬组织的变化。结果骨性组织测量项目中，蝶鞍中心点、鼻根点和上牙槽座点的交角(SNA)、下颌平面与前颅底平面的交角(SN-MP)在矫治后较矫治前均增加(P<0.05)，上牙槽座点、鼻根点和下牙槽座点的交角(ANB)变小(P<0.05)；矫治后观察组较对照组 ANB［.0.22±1.47］比［.1.41±0.99］；SN-MP［31.91±5.81］比［37.07±2.56］；下颌平面与眶耳平面的交角(FH-MP)［22.80±4.14］比［26.74±3.56］；..平面与前颅底平面的交角(OP-SN)［10.42± 4.31］比［15.93±2.10］均减小(P<0.05)。牙性测量项目中，上中切牙长轴到前颅底平面的交角(U1-SN)、下中切牙切点至下颌平面的距离(L1-MP)治疗前后均差异有统计学意义；软组织测量指标上唇凸点至 E线距离(UL-EP)、下唇凸点至 E线距离(LL-EP)、眶耳平面和软组织鼻根点与软组织颏前点连线的后下角(FH-N'Pog')、软组织鼻根点、鼻下点和软组织颏前点连线的夹角(N'-Sn-Pog')在治疗前后均差异有统计学意义。结论数字化隐形矫治技术掩饰性治疗骨性Ⅲ类错..在垂直向控制，减轻牙齿代偿方面较固定矫治技术更有优势。 |

| Objective To investigate the clinical effect of digital invisible orthodontic technology in the treatment of adult mild tomoderate bony class Ⅲ malocclusion.Methods A total of 24 adult patients with mild to moderate bony class Ⅲ malocclusion fromAugust 2019 to August 2021 in Hefei Stomatological Hospital were selected, and the observation subjects were divided into observationand control groups, with 12 cases each. The observation group adopted digital invisible orthodontic technology, and the control groupadopted fixed orthodontic technology,ie,MBT orthodontic technology. The 16 soft and hard tissue indicators of the head lateral radio-graphs before and after treatment were measured to compare the differences in soft and hard tissues after treatment between the twogroups.Results For bone tissue measurements, the intersection angles of the butterfly saddle point, nasal root point and upper alveo-lar seat point (SNA) and the intersection angle between the mandibular plane and the anterior cranial base plane (SN-MP) increased af-ter correction compared to before correction (P<0.05). After orthodontic correction, the ANB in the observation group was [.0.22±1.47]compared with the control group [.1.41±0.99]; the SN-MP [31.91±5.81] vs [37.07±2.56]; the angle of intersection between the mandibu-lar plane and the orbito-orbital plane (FH-MP) [22.80±4.14] compared with [26.74±3.56]; and the angle of intersection between the den-tal plane and the anterior cranial base plane (OP-SN) [10.42± 4.31] than [15.93± 2.10] were reduced (P<0.05). Among the dental mea-surements, the intersection angle from the long axis of the upper central incisor to the anterior cranial base plane (U1-SN) and the dis-tance from the incisal point of the lower central incisor to the mandibular plane (L1-MP) differed statistically before and after treatment;the soft tissue measurements of the distance from the upper lip bump to the E line (UL-EP), the distance from the lower lip bump to the E line (LL-EP), the posterior inferior angle of the line connecting the orbito-ear plane and the soft tissue nasal root point to the soft tis-sue anterior chin point (FH-N'Pog'), and the angle between the line connecting the soft tissue nasal root point, the inferior nasal pointand the soft tissue anterior chin point (N'-Sn-Pog') all differed statistically before and after treatment.Conclusion The digital invisi-ble orthodontic technique for masked treatment of bony Class Ⅲ malocclusion has advantages over fixed orthodontic techniques interms of vertical control and reduction of tooth substitution. |
