【摘要】：目的:通過測(cè)量上頜尖牙在不同時(shí)間內(nèi)不同正畸力值作用下牙齒移動(dòng)的距離,探索牙齒移動(dòng)和最適力的關(guān)系。方法:選取32例處于生長(zhǎng)發(fā)育期的患者為研究對(duì)象,隨機(jī)分成4組。依組別分別對(duì)其上頜右側(cè)的尖牙給予50、100、150、250g的遠(yuǎn)中移動(dòng)的初始力。對(duì)側(cè)尖牙不加力,為對(duì)照組。測(cè)量不同時(shí)間內(nèi)全部樣本左右側(cè)尖牙移動(dòng)的距離。結(jié)果:尖牙受力后不同時(shí)間內(nèi)牙齒移動(dòng)速率不同,有統(tǒng)計(jì)學(xué)意義(P0.01),不同力值作用下的各組牙齒移動(dòng)速率也不同(P0.01),二者有交互作用。結(jié)論:對(duì)于上頜尖牙,當(dāng)正畸加載力小于100g時(shí),移動(dòng)速率隨著力值的增大而不斷增加。但當(dāng)超過100g后,隨著力值的增加,牙齒移動(dòng)速率增加不明顯。
[Abstract]:Objective: to study the relationship between tooth movement and optimal force by measuring the distance of tooth movement under different orthodontic force in different time. Methods: 32 patients were randomly divided into 4 groups. The right canine teeth of the maxilla were given an initial force of 50,150,250g of distal movement by group. The contralateral canine teeth did not add force, as the control group. The distance between left and right canine movement of all samples was measured at different times. Results: the rate of tooth movement was different in different time after force, which had statistical significance (P 0.01). The rate of tooth movement was also different in each group under different force values, and there was interaction between the two groups. Conclusion: for maxillary canine, when the orthodontic loading force is less than 100 g, the moving rate increases with the increase of force. But when more than 100 g, with the increase of force, the rate of tooth movement is not obvious.
