RESUMEN
Objective:To measure the craniofacial soft tissue thickness in female adolescent orthodontic treatment thufferer in Chongqing and to study the craniofacial soft tissue thickness character in female adolescent orthodontic treatment thufferer in Chongqing,analyze the difference of craniofacial soft tissue thickness in Class I,Class II and Class III.Methods:Craniofacial soft tissue thickness at 14 landmarks were measured with DR and statistically analyzed in 60 female adolescent orthodontic treatment thufferers in Chongqing.Results:The measured values were from 5.11?0.52 to 14.18?1.14mm.The craniofacial soft tissue thickness is the thinnest in the root of nose,but the thickest in the lower lip.Conclusions:There is siglificant difference in craniofacial soft tissue thickness among different positions of face in female adolescent orthodontic treatment thufferer in Chongqing.Soft tissue thickness plays the decisive role for individual appearance like the bone tissue.Except for nasal point,lower lip and mentolabial furrow,there are siglificant difference in the basis nasi,upper lip and mental region among Class I,Class II and Class III in female orthodontic treatment thufferer in Chongqing.
RESUMEN
Objective To study the angular characteristics of facial profile in normal Han Chinese adults of Guangdong natives and the value of measurement methods adapted in this project. Methods One hundred and fifty Han Chinese adults (ratio of male to female,1∶1)were randomly chosen and parameters for computer aided angular analysis of facial soft tissues included:lateral angles:∠Ns Prn Pgs;∠Ns Prn GsPgs;∠Ns Prn Sn; As Ns Bs;∠Ns Sn Pgs;∠Gs Ns Prn;∠Cm Sn Ls and ∠Li Bs Pgs. front angles: ∠Zyr Rc Mes; ∠Zyl Lc Mes; ∠Exr Exl Sn; ∠Exl Exr Sn; ∠Exr Sn Exl; ∠Enl Enr Sn; ∠Enr Enl Sn; ∠Enr Sn Enl; ∠Sn Chr Chl; ∠Sn Chl Chr and ∠Chr Sn Chl.Results Lateral angles ∠Ns Prn Sn and ∠Li Bs Pgs,in male were larger significantly than that those in female, but ∠Gs Ns Prn in male was smaller significantly than that in female. Front angles,∠Zyr Rc Mes and ∠Zyl Lc Mes,in male were larger significantly than those in female.Conclusion Angular analysis plays a unique role in the measurement of facial soft tissue profile. There is a difference of facial soft tissue profile between male and female Han Chinese.
