【摘要】：目的:本研究從正畸醫(yī)生與普通群眾的軟組織美學(xué)評(píng)價(jià)出發(fā),尋找與遼寧地區(qū)人群審美相關(guān)的測(cè)量指標(biāo),為正畸治療的診斷與制定計(jì)劃提供符合公眾審美的美學(xué)指標(biāo)參照。方法:根據(jù)納入標(biāo)準(zhǔn)選擇遼寧地區(qū)年輕女性共30名,均為個(gè)別正常(?),年齡18-30歲,平均年齡24±2.7歲。所有入選對(duì)象均拍攝顱面部CBCT,將所得CBCT數(shù)據(jù)在Invivo5.0軟件中重建后轉(zhuǎn)化為頭顱側(cè)位片;再對(duì)入選對(duì)象拍攝側(cè)貌照片,拍攝采用坐姿鏡面位自然頭位。將CBCT轉(zhuǎn)化的頭顱側(cè)位片與自然頭位下側(cè)貌照片導(dǎo)入Adobe Photoshop CS6軟件,對(duì)頭顱側(cè)位片進(jìn)行旋轉(zhuǎn)、縮放、移動(dòng)等處理,使其與自然頭位下側(cè)貌照片重疊,獲得自然頭位下頭顱側(cè)位片,并在軟件中制作該頭位下的側(cè)貌輪廓剪影。分別由29名正畸醫(yī)生及85名普通群眾對(duì)30例自然頭位下側(cè)貌剪影進(jìn)行審美評(píng)價(jià),數(shù)據(jù)收集采用問卷調(diào)查的形式,評(píng)分使用里克特5級(jí)量表。在WinCeph 8.0軟件中編輯制作個(gè)性化的測(cè)量分析程序,對(duì)所有自然頭位下側(cè)位片進(jìn)行各項(xiàng)面部軟組織美學(xué)指標(biāo)測(cè)量。所有測(cè)量值及評(píng)分?jǐn)?shù)據(jù)核查無誤后,錄入Microsoft Excel 2007軟件建立數(shù)據(jù)庫。本研究數(shù)據(jù)結(jié)果的統(tǒng)計(jì)分析均采用SPSS 22.0軟件進(jìn)行。對(duì)兩次美學(xué)指標(biāo)測(cè)量值進(jìn)行配對(duì)t檢驗(yàn),檢查測(cè)量誤差。對(duì)各剪影兩組評(píng)分取均值,所得兩組剪影評(píng)分均值進(jìn)行配對(duì)t檢驗(yàn),判斷正畸醫(yī)生與普通群眾評(píng)分是否存在統(tǒng)計(jì)學(xué)差異。各組剪影評(píng)分與美學(xué)指標(biāo)測(cè)量值進(jìn)行Pearson相關(guān)分析,篩選出與審美評(píng)價(jià)具有相關(guān)性的軟組織美學(xué)指標(biāo),將其作為自變量,兩組評(píng)分值作為因變量,分別進(jìn)行多重線性逐步回歸分析,并獲得回歸方程。所有統(tǒng)計(jì)方法檢驗(yàn)標(biāo)準(zhǔn)均為α=0.05。結(jié)果:正畸醫(yī)生組評(píng)分均值較普通群眾組高0.05分,兩組人群對(duì)個(gè)別正常(?)的審美評(píng)價(jià)差異具有統(tǒng)計(jì)學(xué)意義。Pearson相關(guān)性檢驗(yàn)結(jié)果顯示,影響正畸醫(yī)生與普通群眾審美評(píng)價(jià)的軟組織測(cè)量指標(biāo)均為TLL-TVIL,B'-TVL,Pos-TVL三項(xiàng)指標(biāo)。分別將正畸醫(yī)生組與普通群眾組評(píng)分作為因變量進(jìn)行多因素逐步線性回歸分析后得到回歸方程:正畸醫(yī)生組評(píng)分Y1=1.949-0.068×X1+0.236×X2+0.115×X3,普通群眾組評(píng)分 Y2=2.055-0.080×X1+0.178×X2+0.070×X3。評(píng)分結(jié)果均與 TLL-TVL 呈負(fù)相關(guān),與B'-TVL、Pos-TVL呈正相關(guān),其中B'-TVL的相關(guān)系數(shù)絕對(duì)值最大。隨自變量改變兩組因變量變化趨勢(shì)一致,B'點(diǎn)位置同為對(duì)評(píng)分影響最大的因素。結(jié)論:本研究結(jié)果表明,正畸醫(yī)生與普通群眾對(duì)軟組織側(cè)貌的審美評(píng)價(jià)存在統(tǒng)計(jì)學(xué)差異。其中正畸醫(yī)生打分平均值略高于普通人群,離散度更大,表明正畸醫(yī)生對(duì)側(cè)貌的美學(xué)評(píng)價(jià)更加清晰具體,偏好較明顯,而普通群眾對(duì)軟組織側(cè)貌無一致的審美標(biāo)準(zhǔn),其評(píng)分主要集中于中間段。影響正畸醫(yī)生與普通人群審美評(píng)價(jià)的軟組織測(cè)量指標(biāo)均為TLL-TVL,B'-TVL,Pos-TVL三項(xiàng)指標(biāo),均與自然頭位下真實(shí)垂線相關(guān),表明頭位對(duì)女性軟組織側(cè)貌的審美評(píng)價(jià)存在影響。在考慮軟組織側(cè)貌美學(xué)時(shí)不應(yīng)僅關(guān)注鼻-唇-頦三者的相對(duì)位置關(guān)系,也應(yīng)將頭位因素考慮在內(nèi)。根據(jù)本研究得出的回歸方程可以看出,無論正畸醫(yī)生組還是普通群眾組,TLL-TVL值均與評(píng)分成負(fù)相關(guān),而B'-TVL值和Pos-TVL值均與評(píng)分成正相關(guān),其中B'-TVL值對(duì)審美評(píng)價(jià)影響最顯著。這一結(jié)果提示在一定取值范圍內(nèi),正畸醫(yī)生與普通人群的審美偏好均傾向于在自然頭位下下唇相對(duì)后縮、軟組織頦部較為突出的側(cè)貌,B'點(diǎn)與自然頭位下鉛垂線的距離應(yīng)著重考慮。研究中所得回歸方程可用于比較矯治前后的軟組織側(cè)貌美觀程度,矯治前計(jì)算所得評(píng)分可作為確定臨床矯治計(jì)劃的參考。
[Abstract]:Objective : Based on the soft tissue aesthetics evaluation of orthodontist and common people , this paper finds out the measurement index related to the aesthetics of the population in Liaoning , and provides the aesthetic index reference for the diagnosis and development of orthodontic treatment . The method includes selecting 30 young women in Liaoning area according to the inclusion criteria , all of them are normal ( ? All selected subjects were examined and evaluated by using SPSS 10.0 software . The results showed that the average scores of the two groups were measured by SPSS software . The results showed that the average values of the two groups were measured by SPSS software . The results showed that the average scores of the two groups were measured by SPSS software . The results showed that the average scores of the two groups were measured by SPSS software . The results suggest that the aesthetic preference of the orthodontist and the general population is related to the true vertical line under the natural head position , and the B ' - TVL value and the Pos - TVL value are all positively correlated with the score . The regression equation in the study suggests that the regression equation can be used to compare the aesthetic degree of soft tissue side before and after treatment . The score obtained before treatment can be used as a reference for determining clinical treatment plan .
