摘要
目的探讨骨性Ⅱ类面型与正常面型的颅面形态三维测量数据差异。方法选取2019年10月-2021年4月我院口腔正畸科收治的30例骨性Ⅱ类面型患者,设为研究组;另选取同期体检的20例正常面型志愿者作为对照组。对2组对象进行面部激光表面三维扫描,计算并比较2组颅面形态的面部比例指数。结果颅面形态三维测量显示,研究组前额-面宽指数、鼻根-眶间宽指数、鼻-下面高指数、上面-全面高指数和上唇-下颌高指数均大于对照组(P<0.05),下颌宽-面宽指数、前额-颅底基底宽指数、面宽-颅底基底宽指数、口宽-上唇弧长指数、下唇-上唇弧长指数、下面-全面高指数、下唇-上唇高指数、下颌-下面高指数显著小于对照组(P<0.05)。结论骨性Ⅱ类面型的颅面形态三维测量值与正常面型存在明显区别,主要表现为下颌发育不足、面型较凸、鼻根较宽、上唇较高、下唇较上唇弧长短等方面,临床正畸矫治时需引起重视。
Objective To investigate the difference of three-dimensional measurement data of craniofacial morphology between skeletal Class Ⅱ facial form and normal facial form.Methods 30 patients with skeletal Class Ⅱ facial form treated in the Department of orthodontics of our hospital from October 2019 to April 2021 were selected as the study group.ln addition,20 normal facial volunteers who underwent physical examination in the same period were selected as the control group.The facial laser surface three-dimensional scanning was performed on the two groups,and the facial proportion index of craniofacial morphology was calculated and compared between the two groups.ResultsThe three-dimensional measurement of craniofacial morphology showed that the forehead face width index,nasal root orbital width index,nose lower height index,upper overall height index and upper lip mandibular height index in the study group were higher than those in the control group(P<0.05).The mandibular width face width index,forehead Skull base width index,face width skull base width index,mouth width upper lip arc length index,lower lip upper lip arc length index The lower overall high index,lower lip upper lip high index and lower jaw lower high index were significantly lower than those in the control group(P<0.05).Conclusion The three-dimensional measurement of craniofacial morphology of skeletal Class Ⅱ face type is significantly different from that of normal face type,mainly in the aspects of insufficient mandibular development,convex face type,wide nasal root,higher upper lip,lower lip and upper lip arc length,which should be paid attention to in clinical orthodontic treatment.
