差动直丝弓矫治技术对打开咬颌过程中不同磨牙后倾弯曲度的影响

Influence of differential straight wire appliance on the bending degree of different molar in the process of open bite

目的:研究差动直丝弓矫治技术对打开咬颌过程中不同磨牙后倾弯曲度的影响效果,分析差动直丝弓矫治技术的临床应用价值。方法:收治打开咬颌行为障碍患者80例,采用差动直丝弓矫治技术,分析治疗后患者打开咬颌过程中不同磨牙倾弯曲度的影响表现及具体情况。结果:总体治疗效果良好,共出现35°32例、40°41例、45°7例3种倾弯曲度,倾弯曲度越小,患者下颌前牙压根、牙周膜所受应力越小,患者打开咬颌配合表现大多好转。结论:差动直丝弓矫治技术可以提高磨牙效果,通过获取患者准确牙后倾弯曲度,配备打开咬颌行为采取治疗,其临床价值很高。

Objective:To study the effect of differential straight wire appliance on the bending degree of different molar in the process of open bite,and to analyze the clinical application value of the differential straight wire appliance.Methods:80 patients with open bite behavior disorder were selected.All patients were treated with differential straight wire appliance.We analyzed the influence of the different molar inclination of the patients after the treatment and the specific situation.Results:The overall treatment effect is good.There were three kinds of bending,32 cases of 35 °,41 cases of 40 °,7 cases of 45 °.The smaller the bending degrees,patients with mandibular anterior teeth,periodontal membrane by the stress at the smaller.Patients with open bite with the most improved performance.Conclusion:Differential straight wire appliance technique can improve the effect of molar teeth.The clinical value is very high by obtaining the right degree of inclination of the tooth,combined with open bite behavior for treatment.
