【摘要】：目前，對于正畸和正頜外科醫(yī)生而言，X線頭影測量分析是患者診斷、治療的重要依據(jù)，而對于患者來說，特別是年輕成人，他們在功能改善的同時更期望獲得面型的美觀。然而多項研究表明，面部的軟硬組織形態(tài)并非完全一致，軟組織一方面可以掩蓋硬組織的某些缺陷，有時也可以將這部分缺陷進一步放大。因此，軟組織側(cè)貌的研究日漸成為正畸正頜領(lǐng)域的一個重要研究方向。 實驗?zāi)康模鹤匀活^位下拍攝，獲得中國北方正常年輕成人的軟組織側(cè)貌照片，測量各部位的角度值并加以分析，建立一個關(guān)于中國北方正常年輕成人的軟組織側(cè)貌角度值的基本數(shù)據(jù)庫，為正畸和正頜外科醫(yī)師提供臨床參考。 實驗方法：實驗對象的選擇為吉林大學新民校區(qū)將近5000名學生，初篩選由兩名實驗人員進行，選取標準為中國北方人、口內(nèi)咬合關(guān)系良好，前牙覆合、覆蓋基本正常，磨牙關(guān)系為Ⅰ類，中線基本無偏移等，從中選出155名基本符合標準的人，然后再由5名普通人和5名專業(yè)的正畸醫(yī)師組成的評委會篩選出他們認為側(cè)貌比例協(xié)調(diào)者，最終的實驗對象的選擇應(yīng)為至少5人認同，才能被納入。在篩選時，盡量只關(guān)注面部比例是否協(xié)調(diào)，而將影響到評價的主觀因素（如眼睛）去除。按照以上標準，共選取出實驗對象113名（女67名，男46名），年齡范圍是18~30歲，平均年齡為23歲。在嚴格的拍攝標準下，放置鉛垂線和尺度工具來確保照片的放大率為1:1，以最大可能減小照片的變形率，而鉛垂線被認為是真正垂直于水平地平面的線，并以此作為參考線對面部突度進行分析，拍攝自然頭位下的照片。通過Coreldraw軟件，對軟組織側(cè)貌進行定點測量分析，共測量面部角度12項。所得數(shù)據(jù)使用SPSS17.0統(tǒng)計軟件進行處理分析并比較男女之間的性別差異。使用Dahlberg’s公式檢測測量方法的可靠性。 結(jié)果：本次研究得到了中國北方正常年輕成人軟組織側(cè)貌角度的最大值、最小值、平均值及標準差。平均值結(jié)果顯示除垂直鼻角外，女性的角度評價值多數(shù)比男性偏大，說明女性的面部輪廓更顯柔和。鼻唇角，頦唇角的標準差比較大，說明個體之間這些值差異比較大。男女之間的面部角度存在明性別差異的角度有6個，分別是前鼻角（G-N-Prn）、鼻尖角（N-Prn/Sn-Cm）、垂直鼻角（Prn-N/TVL）、頦唇角（Li-Sm-Pg）、面凸角（G-Sn-Pg）、全面凸角（G-Prn-Pg）、上三角（Pg-G-Prn）。 本研究顯示除鼻唇角、頦唇角、下面角外，各角度測量的方法誤差均不大，說明該測量方法是可行的。鼻唇角、頦唇角、下面角的方法誤差較大可能是由于定點各點距離比較接近所致也可能是由于鼻小柱點和頦下點難以定點所致。 結(jié)論：女性角度的平均值多數(shù)比男性偏大。軟組織側(cè)貌有的角度存在明顯性別差異，，在臨床正畸和正頜外科制定診斷治療計劃時需注意性別差異。鼻唇角和頦唇角的標準差和方法誤差均比較大，臨床應(yīng)用時應(yīng)慎重。
[Abstract]:At present, for orthodontics and orthognathic surgeons, cephalometric analysis is an important basis for the diagnosis and treatment of patients, but for patients, especially young adults, While improving their function, they are more likely to get the appearance of the face. However, several studies have shown that the hard and soft tissues of the face are not exactly the same in shape, and on the one hand, the soft tissue can cover up some defects in the hard tissue. Sometimes these defects can be further magnified. Therefore, the study of soft tissue profile is becoming an important research direction in orthodontic orthognathic field. Objective: to obtain the soft tissue profile photos of normal young adults in northern China, and to measure the angle values of different parts and analyze them. To establish a basic database of soft tissue profile angle of normal young adults in North China to provide clinical reference for orthodontics and orthognathic surgeons. Methods: the subjects were selected as nearly 5000 students in Xinmin Campus of Jilin University. The initial screening was carried out by two experimenters. The selection criteria were northern Chinese, with good oral occlusion, close anterior teeth, and normal coverage. The molar relationship was classified as Class I, and there was basically no deviation in the middle line. 155 people who basically met the criteria were selected, and then selected by a jury composed of five ordinary people and five orthodontists who specialized in orthodontics to select those who they thought were in line with the profile ratio. The final selection of subjects should be identified with at least five people to be included. When screening, try to focus only on whether the facial proportion is coordinated, and remove the subjective factors (such as the eyes) that affect the evaluation. In accordance with the above criteria, A total of 113 subjects (67 females and 46 males) were selected. The age range was 1830 years, with an average age of 23 years. Plumb lines and scale tools are placed to ensure a magnification of 1: 1 to minimize the distortion of the photos, which are considered to be truly perpendicular to the horizontal plane and are used as reference lines for the analysis of facial protrusions. The soft tissue profile was measured and analyzed by Coreldraw software. A total of 12 items of facial angle were measured. The data were processed and analyzed by SPSS17.0 statistical software and the gender differences between men and women were compared. The reliability of the measurement method was tested by Dahlberg's formula. Results: in this study, the maximum, minimum, mean and standard deviation of soft tissue profile angle of normal young adults in North China were obtained. It shows that the facial contour of women is softer. The standard deviation of nose-lip angle and genial-labial angle is relatively large, which indicates that there are large differences in these values among individuals. There are six different angles of facial angle between men and women. They are G-N-Prng, N-Prn / Sn-CmN, Prn-N- / TVLV, Li-Sm-PgP, G-Sn-Pg, G-Prn-Pgn, Pg-Pg-Prnn, and Pg-Pg-Prnn, respectively, in the anterior nasal horn, in the tip of the nose, in the vertical-nasal angle, in the upper triangle, in the chin and lip, in the chin lip, in G-Sn-Pg, in the upper triangle, in the upper triangle, and in the upper triangle. This study shows that the errors of all the angles except the nose-lip angle, the genial-labial angle and the lower angle are small, which shows that the measurement method is feasible, the nose-lip angle, the genial-labial angle, the nose-lip angle, the genial-labial angle, The error of the lower angle may be due to the close distance between the different points of the fixed point or the difficulty of fixing the nasal column and the submental point. Conclusion: the average angle of female is larger than that of male. In clinical orthodontics and orthognathic surgery, attention should be paid to gender differences in the diagnosis and treatment plan. The standard deviation and method error of nose-lip angle and genial-labial angle are large, so we should be careful in clinical application.
