摘要
目的 :比较FRⅢ型矫治器矫治功能性和早期骨性安氏Ⅲ类错前、后软组织的变化。方法 :选择30例功能性和早期骨性安氏Ⅲ类错患者,利用FRⅢ型矫治器矫治,采用SPSS22.0软件包对矫治前、后的X线头影测量项目进行t检验。结果:FRⅢ型矫治器矫治前、后,面型角、鼻唇角、颏唇角、上唇-E线距离均显著增大(P<0.05),Z角显著减小(P<0.05),下唇-E线距离显著减少(P<0.01);H角、上唇沟深、颏唇沟深、上唇基厚度、上唇紧张度均无显著改变(P>0.05)。结论:经FRⅢ型矫治器矫治后的安氏Ⅲ类错患者,侧貌突度增大,Ⅲ类凹面型趋于平直,面部侧貌趋于美观;上唇近中移动,下唇远中移动,上唇突度增加。
PURPOSE： To compare the changes of soft tissues before and after treatment of functional and skeletal Angle class Ⅲ malocclusion with FRⅢ appliance. METHODS： Thirty patients with functional and skeletal Angel Class Ⅲ malocclusion were selected and treated with FRⅢ appliance,SPSS 22 software package was used to analyzed soft tissue changes before and after treatment. RESULTS： After treatment, FCA,NLA, Pog labial angle,upper lip to E line were increased significantly （P〈0.05）. Z angle was decreased significantly （P〈0.05）. Lower lip to E line was decreased significantly （P〈0.01）. There was no significant difference in H angle, superior sulcus depth, inferior sulcus to H-line, basic upper lip thickness, upper lip strain measurement （P〉0.05）. CONCLUSIONS： After FRⅢ appliance treatment of Angel Class Ⅲ malocclusion, the convexity of facial profile was increased, type Ⅲ concave profile tends to be flat, the facial profile of patient become more attractive; the protrusion of upper lip was found, the retrusion of lower lip was also present, the convexity of upper lip was increased.
