摘要
目的探究广东地区安氏Ⅰ类双牙弓前突错(牙合)畸形拔牙正畸后女性唇部软组织厚度及唇部回收的关系。方法选取2020年1月~2023年12月期间在我院门诊正畸科就诊的成年女性患者120例,所有患者接受头颅侧位片拍摄并测量唇部软组织厚度,依据唇厚度分类标准分为薄唇型、均衡型及厚唇型,分析不同唇型软组织厚度切牙上唇回收比及唇厚度与切牙上唇相关性。结果三组不同唇厚度组在对比△Is-Y、△Ls-Y指标上均存在差异,P<0.05,其中薄唇组唇部回收量大,唇厚组回收量较小;正畸前及正畸治疗后,唇厚组患者软组织厚度高于薄唇组、均衡组,在正畸治疗前后三组软组织厚度均呈现改变,但薄唇组改变情况更为显著,P<0.05;唇部软组织厚度与唇部回收程度呈负相关,当回收程度越高则表明唇部软组织厚度越薄,P<0.05。结论女性错(牙合)人群中在正畸治疗期间上唇软组织厚度会影响到唇部回收程度,且呈负相关,为此需采取针对性措施调整正畸治疗方案,保障正畸效果。
Objective To study the relationships between the female’s lip soft tissue thickness and lip recovery during the orthodontic treatment of Angle Class I protrusion malocclusion patients in Guangdong province.Methods 120 female patients treated from January 2020 to December 2023 in our orthodontics department were selected.The skull lateral projection was used to measure the lip soft tissue thickness.Patients were assigned to thin group,even group and thick group.The correlations of incisor tooth upper lib recovery rates and lip thickness with the incisor tooth upper limb were analyzed.Results△Is-Y and△Ls-Y values among three groups were significantly different(P<0.05);the lip recovery degrees in thin group were high,but low in thick group;before and after the orthodontic treatment,the lip soft tissue thickness in thick group was higher than thin group and even group;the soft tissue thickness for three groups was changed,especially for the thin group(P<0.05);the lip soft tissue thickness was negatively correlated with the lip recovery degrees;the higher the lip recovery degree was,the thinner the lip soft tissue thickness was(P<0.05).Conclusion During the orthodontic treatment of Angle Class I protrusion malocclusion,the female’s lip soft tissue thickness is negatively correlated with the patient’s lip recovery degrees.Therefore,the specific measures shall be taken to ensure the final treatment effects.
