EGA在儿童安氏Ⅱ类错合畸形早期矫治中的应用
|
摘要
目的探讨EGA在儿童安氏Ⅱ类错合畸形早期矫治中的应用价值。方法选择就诊于乌鲁木齐市口腔医院儿童牙病科混合牙列期的安氏Ⅱ类错合畸形患儿46例,男性24例,女性22例,年龄6～9岁,采用自身配对设计,对治疗前后的头影测量数值和模型测量数值进行统计学分析。结果通过EGA治疗后,46例患儿的SNB、FH-MP、MP-SN、L1-MP和LL-E值较治疗前增大,ANB和U1-L1值较治疗前减小,差异均有统计学意义(P <0.05)。上颌拥挤量和下颌拥挤量值较治疗前减少,上下颌拥挤量明显改善,差异均有统计学意义(P <0.05)。结论采用EGA治疗儿童安氏Ⅱ类患者的下颌发育不足,打开咬合,缓解上下颌牙列拥挤,刺激下颌骨向前生长发育,同时也纠正了吐舌、口呼吸等不良习惯,改善患儿覆合、覆盖及咬合关系,为患儿后期的正畸矫治降低了难度。
Objective To explore the application value of Eruptione Guidance Appliance(EGA)in early rectification of class II malocclusion in children.Methods The data of cephalometry and model measurements of 46 children with Angle class Ⅱ malocclusion in mixed dentition stage were collected.The children included 24 males and 22 females,aged 6-9years.The results were compared on the self-matched basis.Results After treatment with EGA appliance,the level of SNB,FH-MP,MP-SN,L1-MP and LL-E increased in 46 children,in which the values of SNB increased about 1degree,while the level of ANB and U1-L1 decreased compared with those before treatment(P <0.05).The maxillary and mandibular crowding volume decreased,and the jaw and mandible crowding volume improved significantly(P <0.05).Conclusion The EGA appliance reduce the difficulty of orthodontics which is used to treat children with mandibular deficiency of ClassⅡ malocclusion,open bite,relieve crowded malalinement,stimulate forward growth and development of mandible,meanwhile correct bad habits of tongue thrust and mouth breathing and improve patients overbite,overjet and occlusal relation.
