摘要： 目的:探讨FRⅢ矫治器治疗前后患者颌面软、硬组织变化及矢状向软硬组织变化间的相关性。方法:纳入安氏Ⅲ类错牙合患者22例为观察组,在初诊时纳入38例年龄与观察组匹配,且错牙合类型及骨骼形态与观察组接近的患者为对照A组,纳入42例年龄与观察组治疗12个月时相匹配,且错牙合类型及骨骼形态与观察组接近的患者为对照B组。分别于观察组初诊时及治疗12个月时、对照组入院时,拍摄头颅定位侧位片,观察3组硬组织、软组织及矢状向软硬组织相关性指标变化情况。结果:与对照A组相比,观察组在初诊时各指标对比,差异无统计学意义;与对照B组相比,观察组在治疗12个月时下颌体长明显更短、后面高明显更低、ANB角明显更高、SNB角明显更低、MP/SN明显更高、OP/SN明显更高、上唇紧张度指标明显更高、鼻唇角明显更高、颏唇角明显更高、Z角明显更低,上述指标对比,差异均有统计学意义(P＜0.05)。观察组治疗前后上颌骨基骨位置及上切牙切缘位置的变化量与鼻底点位置、上及下唇突点位置、软组织颏前点位置变化量正相关,下切牙切缘位置的变化量与软组织颏前点位置变化量正相关(P＜0.05)。结论:FRⅢ矫治器对下颌生长有抑制作用,可促进下颌后下旋转,能够增加鼻唇角、颏唇角,减少Z角;其所引起的软硬组织变化有一定相关性。

Abstract: Objective: To investigate the changes in dental, skeletal, and soft tissue of maxillofacial region after 12 months of FRⅢ treatment, and to analyze the correlation between the movement of hard and soft tissues. Methods: Twenty-two patients with functional Class Ⅲ malocclusions were included in the observation group. Thirty-eight cases with similar occlusal and skeletal characters whose age matched with the observation group at the time of diagnosis were included in the control group A. Forty-two cases with similar occlusal and skeletal characters whose age matched with the observation group after 12 months of treatment were included in the control group B. The cephalograms of patients in the observation group were taken before and 12 months after treatment, the cephalograms of patients in the control group were taken when entering hospital. The changes in indexes of hard tissue, soft tissue, and correlation between sagittal soft and hard tissues were compared. Results: Compared with the control group A, all indexes in the observation group at the time of diagnosis were not significant different. Compared with the control group B, in the observation group after 12 months of treatment, the mandible length were shorter, posterior facial height were lower, ABN were wider, SNB were narrower, MP/SN and OP/SN were wider, the index of upper lip tension were higher, nasolabial angle were wider, chin angle were wider, Z angle were narrower, and the differences above were statistical significant different (P＜0.05). In the observation group, the changes of position of upper jaw bone and upper incisors were positively correlated with the changes of position of nose bottom point, upper lip protrusion point, lower lip protrusion point and soft tissue chin point (P＜0.05). The changes of position of lower incisors were positively correlated with the changes of position of soft tissue chin point (P＜0.05). Conclusion: FRⅢ appliance can restrain the growth of mandible, promote the mandibular rotation, increase the nasolabial angle, chin angle, and reduce Z angle. The changes of soft and hard tissues have certain correlation.
