舌栅联合[牙合]垫式矫治器矫治乳牙期前牙反[牙合]的疗效分析

Efficacy analysis of patients with anterior crossbite malocclusion following treatment through tongue crib combined with occlusal pad

目的:研究舌栅联合[牙合]垫式矫治器早期矫治乳前牙反[牙合]的临床疗效。方法:选择乳牙期前牙反[牙合]病例80例,实验组和对照组各40例,实验组采用舌栅联合[牙合]垫式矫治器,对照组采用传统[牙合]垫式矫治器。通过X线头影测量技术,对比分析两组病例治疗前后颌骨、牙齿、软组织及舌骨位置的变化。结果:实验组与对照组比较,ANB及UI-SN角、上唇突度(UL-SnPos)增大,鼻唇角(Cm-Sn-UL)减小,舌栅联合[牙合]垫式矫治器对患者上下颌[牙合]关系不调及面型改善更明显;H-RGn、H-S、H-FH距离增大,H-C3距离减小,舌栅联合[牙合]垫式矫治器使舌骨向后下移位明显。结论:舌栅联合[牙合]垫式矫治器能有效地矫治乳牙期反[牙合],对患者的舌骨位置影响尤为显著,可以应用于临床。

Objective:This study aims to study the clinical effect of tongue crib combined with occlusal pad appliance in the early treatment of primary anterior crossbite.Methods:There were 80 cases of anterior crossbite in deciduous teeth selected,40 cases in experimental group were treated with tongue crib combined with occlusal pad appliance,and 40 cases in control group were treated with traditional occlusal pad appliance.The changes of jaw,teeth,soft tissue and hyoid in the two groups before and after treatment were analyzed by cephalometric technique.Results:Compared with the control group,ANB,UI-SN,UL-SnPos increased in experimental group,Cm-Sn-UL decreased in experimental group,the tongue crib combined with occlusal pad appliance was effective in the treatment of malocclusion of the upper and lower teeth and the facial form of the patients significantly,H-RGn,H-S,H-FH increased,H-C3 decreased,and the tongue crib combined with occlusal pad appliance made the hyoid move backward and downward.Conclusion:Tongue crib combined with occlusal pad appliance can effectively treat deciduous crossbite,especially for the position of hyoid bone,and can be used in clinical practice.
