摘　　要：目的评估自锁托槽和传统结扎式托槽非拔牙矫治牙列拥挤患者的临床效果。方法选取2019年1月—2021年2月该院行牙列拥挤治疗的103例患者为研究对象。依据不同治疗方式分为对照组和观察组。对照组予结扎式托槽矫治;观察组予自锁托槽矫治。评估两组疗效、牙弓宽度及面部软组织情况。结果观察组总有效率(96.15%)高于对照组(76.47%),差异有统计学意义(χ^(2)=8.493,P=0.004);经治疗,观察组各牙弓宽度[(43.87±1.52)、(45.18±1.57)、(51.85±1.41)、(33.97±1.51)mm]高于对照组[(41.28±1.47)、(43.27±1.46)、(50.01±1.38)、(32.15±1.47)mm],差异有统计学意义(t=-8.788、-6.391、-6.692、-6.197,P<0.001)。观察组ULP(10.42±0.21)°、Li-E(-2.23±1.04)mm及Ls-E(-1.75±0.93)mm,低于对照组(11.05±0.23)°,(-4.19±1.38)mm、(-3.69±1.25)mm,SnLs-SiL(138.97±10.26)°高于对照组(128.44±12.05)°,差异有统计学意义(t=14.522、-8.151、-8.948、-4.778,P<0.001)。结论相较于传统结扎式托槽非拔牙矫正方式,应用自锁托槽矫正牙列拥挤患者的效果更佳,能有效提高治疗效果,改善牙弓宽度和面部软组织指标,值得进一步应用和推广。Objective To evaluate the clinical effects of self-locking brackets and traditional ligation brackets for non-extraction patients with crowded dentition.Methods Selected 103 patients with crowded dentition treatment in the hospital from January 2019 to February 2021.According to different treatment methods,they were divided into control group and observation group.The control group was treated with ligature brackets;the observation group was treated with self-locking brackets.The curative effect,the width of the dental arch and the condition of the facial soft tissues were evaluated in the two groups.Results The total effective rate(96.15%)of the observation group was higher than that of the control group(76.47%),the difference was statistically significant(χ^(2)=8.493,P=0.004);after treatment,the width of each arch in the observation group was[(43.87±1.52)mm,(45.18±1.57)mm,(51.85±1.41)mm,(33.97±1.51)mm]higher than the control group[(41.28±1.47)mm,(43.27±1.46)mm,(50.01±1.38)mm,(32.15±1.47)mm],the difference was statistically significant(t=-8.788,-6.391,-6.692,-6.197,P<0.001).The ULP(10.42±0.21)°Li-E(-2.23±1.04)mm and Ls-E(-1.75±0.93)mm of observation group was lower than the control group(11.05±0.23)°,(-4.19±1.38)mm,(-3.69±1.25)mm,SnLs-SiL(138.97±10.26)°higher than the control group(128.44±12.05)°,the difference was statistically significant(t=14.522,-8.151,-8.948,-4.778,P<0.001).Conclusion Comparing with the traditional ligation bracket non-extraction method,the application of self-locking brackets is better for patients with crowded dentition.It can effectively improve the treatment effect and improve the width of the dental arch and facial soft tissue indicators.It is worthy of further application and promotion.
