【摘要】：目的： 在臨床檢查中,經(jīng)�？梢钥吹藉e(?)畸形患者中存在舌系帶異常的情況,而舌系帶異常在不同錯(?)中有所差別,如舌系帶較短在反(?)患者中比較常見,而深覆蓋患者中卻比較少見,舌系帶長度是否與錯(?)畸形的發(fā)生有關系及有何關系值得研究。本研究對舌系帶的長度與矢狀骨面型間的相關性進行了分析,以期為臨床骨性畸形的防治提供參考。 方法： 研究對象均為山東大學口腔醫(yī)院就診的成年患者,共分為3組,骨性Ⅰ類患者(0°≤ANB角≤5°)23人,骨性Ⅱ類患者(ANB角5°)19人,骨性Ⅲ類患者(ANB角0°)22人。本研究采用間接測量法來測量舌系帶的長度,并對每位患者的頭顱側位片進行測量,計算相應的指標。實驗采用t檢驗分析來比較每組內舌系帶長度的性別差異,Scheffe檢驗比較組間舌系帶長度的差異性,Pearson相關性分析來檢驗舌系帶的長度與頭顱側位片分析結果中的所有變量之間的相關關系。 結果： 舌系帶長度在每組內無明顯性別差異(P0.05)。骨性Ⅲ類患者的舌系帶長度較骨性Ⅱ類和骨性Ⅰ類患者的顯著減少(P0.01)。骨性Ⅱ類患者的舌系帶長度與骨性Ⅰ類患者的舌系帶長度間無明顯差異(P0.05)。舌系帶長度與SNB角(P0.01)、下頜骨長度(P0.01)及上下中切牙夾角(P0.05)呈顯著負相關關系。舌系帶長度與ANB角、Wits值呈顯著正相關關系(P0.01)。 結論： 1.相同矢狀骨面型的人群內,舌系帶長度無明顯性別差異。 2.骨性Ⅲ類患者的舌系帶長度較骨性Ⅱ類和骨性Ⅰ類患者舌系帶長度顯著減少,提示舌系帶過短可能是造成骨性Ⅲ類錯(?)畸形的病因之一,故在臨床檢查中應注意舌系帶長度的檢查。 3.舌系帶長度與SNB角、ANB角、Wits值、下頜骨長度及上下中切牙夾角有相關性。舌系帶越短,SNB角、下頜骨長度及上下中切牙夾角越大,而ANB和Wits值越小。
[Abstract]:Objective: in clinical examination, we can often see mistakes (?) Abnormal tongue bands were found in patients with malformation, and abnormal tongue bands were found in different errors (?) There is a difference, such as a shorter tongue band in the opposite direction (?) It is more common in patients, but rare in patients with deep coverage. Is the length of the tongue tied to the error (?) The relationship between the occurrence of malformation and its relationship is worth studying. This study analyzed the correlation between the length of the tongue mesenchyma and the sagittal bone type in order to provide reference for the prevention and treatment of clinical bone deformities. Methods: all the adult patients in the Stomatology Hospital of Shandong University were divided into 3 groups: 23 patients with bone type 鈪，
