【摘要】：目的 探討三種舌側(cè)托槽分別和四種弓絲組合時，在兩種不同的結(jié)扎方式下，后牙段摩擦力的差異。 方法 在干燥、室溫的條件下，采用2種結(jié)扎方式：實驗一組，結(jié)扎絲結(jié)扎；實驗二組，彈性結(jié)扎圈結(jié)扎，分別測試3種不同的舌側(cè)托槽：e-brace個性化舌側(cè)托槽、STb舌側(cè)托槽、普特舌側(cè)托槽，和四種不同弓絲：0.016英寸鎳鉬合金圓絲（β鈦絲，簡稱以下TMA絲）、0.016英寸不銹鋼（stainless steel wire,以下簡稱SS絲）圓絲、0.016×0.022英寸鎳鉬合金方絲、0.016×0.022英寸不銹鋼方絲，結(jié)扎時，在后牙弓段所產(chǎn)生的最大靜摩擦力及平均動摩擦力。 結(jié)果 1.實驗一組與實驗二組，即結(jié)扎絲結(jié)扎與彈性結(jié)扎圈結(jié)扎，，無論是最大靜摩擦力還是平均動摩擦力，在同種弓絲和同種托槽的條件下的摩擦力大小差異都有統(tǒng)計學(xué)意義，結(jié)扎絲結(jié)扎時產(chǎn)生的摩擦力小于彈性結(jié)扎圈結(jié)扎； 2.無論是最大靜摩擦力還是平均動摩擦力，用相同的結(jié)扎方式和相同尺寸、相同材質(zhì)的弓絲組合時，兩實驗組中e-brace個性化舌側(cè)托槽的摩擦力，均比STb舌側(cè)托槽以及普特舌側(cè)托槽大，且有統(tǒng)計學(xué)意義（P0.01）,但是STb舌側(cè)托槽與普特舌側(cè)托槽間摩擦力的差異大多并無統(tǒng)計學(xué)意義； 3.四種弓絲間的摩擦力比較：在同種托槽時，同尺寸的方型弓絲，SS絲的摩擦力相對TMA絲小，且有統(tǒng)計學(xué)意義（P0.05）； 4.通過多元線性回歸分析，在影響摩擦力的因素中，對摩擦力影響大小的因素依次為：托槽的種類、弓絲、結(jié)扎方式。 結(jié)論 1.在相同狀態(tài)下，即同種弓絲同種結(jié)扎方式時，3種舌側(cè)托槽的最大靜摩擦力均大于平均動摩擦力； 2.相同條件下彈性結(jié)扎圈結(jié)扎比結(jié)扎絲結(jié)扎的摩擦力大； 3. e-brace個性化舌側(cè)托槽的摩擦力明顯大于STb、普特舌側(cè)托槽； 4.方型弓絲的摩擦力大于圓形弓絲； 5.托槽的種類、弓絲和結(jié)扎方式都是影響舌側(cè)矯治系統(tǒng)摩擦力的影響因素。其中，托槽種類對摩擦力的的影響最大。
[Abstract]:Objective to explore the difference of friction in posterior teeth under two different ligation modes when three lingual brackets and four arch wires were combined. Methods under the condition of drying and room temperature, two kinds of ligation methods were adopted: experimental group 1, ligation of silk, experimental group 2, elastic ligation ring ligation, Three kinds of tongue side brackets: 1: e-brace, 3 different tongue side brackets: STB, Putt tongue side brackets, and 4 different bow wires: 0. 016 inch nickel molybdenum alloy round wire (尾-titanium wire) were tested. The circular wire of 0.016 脳 0.022 inch Ni-Mo alloy square wire is 0.016 脳 0.022 inch stainless steel square wire. The maximum static friction force and the average dynamic friction force in the posterior arch are obtained during ligation. Result 1. The maximum static friction force and average dynamic friction force of experiment group one and experimental group two, that is, ligation of wire ligation and elastic ligation ring, have statistical significance under the same arch wire and the same bracket. The friction produced by ligation is less than that by elastic ligation; 2. No matter the maximum static friction force or the average dynamic friction force, with the same ligation mode, the same size and the same material of bow wire combination, the friction force of the tongue side bracket in the two experimental groups was individualized. Both of them were larger than those of STB and Putt, but there was no significant difference in friction between STB and Putt. 3. Comparison of friction between four kinds of bow wires: in the same bracket, the friction force of the same size square arch wire SS wire is smaller than that of TMA wire, and has statistical significance (P 0.05); 4. By multivariate linear regression analysis, among the factors affecting friction, the order of factors affecting friction is: the type of bracket, bow wire, ligation mode. Conclusion 1. Under the same condition, that is, the maximum static friction force of the three tongue side brackets is higher than the average dynamic friction force when the same arch wire is ligated in the same way; 2. Under the same condition, the friction force of elastic ligation ring is greater than that of ligation wire. 3. The friction force of e-brace individualized tongue side bracket is obviously higher than that of STB, Putt tongue side bracket; 4. The friction force of square arch wire is greater than that of circular arch wire; 5. The types of brackets, arch wire and ligation are the factors that affect the friction of lingual orthodontic system. Among them, the type of bracket has the greatest effect on friction.
