摘 要:目的:研究LM-Dental软体早期矫治器在骨性Ⅰ类、Ⅱ类儿童患者治疗的临床疗效及对牙颌面生长发育的影响。方法:选取2018年9月~2020年10月就诊的替牙期错(牙合)畸形15例骨性Ⅰ类和24例骨性Ⅱ类患儿,应用LM-Dental软体早期矫治器进行I期治疗,观察骨性Ⅰ类、骨性Ⅱ类治疗前后骨组织、牙组织和软组织变化。结果:LM-Dental软体早期矫治器I期治疗后,患儿ANB角均趋近于骨性Ⅰ类均值,其中骨性Ⅱ类效果更为显著,与骨性Ⅰ类治疗后相比具有统计学意义(P<0.05)。上下切牙交角达到正常值,有效改善因前牙交角过大造成的面部前突;前上面高、前下面高增加使得面下1/3面容更加饱满,差异均具有统计学意义(P<0.05)。结论:LM-Dental软体早期矫治器治疗骨性Ⅰ类、Ⅱ类患儿能够有效改善前牙覆(牙合)覆盖,适当促进上下颌骨的协调发育,为今后恒牙期青少年综合性矫治打下良好基础。Objective:To investigate the clinical effect of using soft appliances in skeletal Class Ⅰ and Class Ⅱ children and its influence on the dental maxillofacial development.Methods:From September 2018 to October 2020,15 cases of skeletal Class Ⅰ malocclusion and 24 cases of skeletal Class Ⅱ malocclusion in mixed dentition who were selected for comparative observation, application of soft early appliance(LM-Dental)for phase I treatment.The changes of bone tissue, dental tissue and soft tissue before and after treatment in children with skeletal Class Ⅰ and skeletal Class Ⅱ were compared.Results:After the use of LM-Dental(LM-Dental)stage I treatment, the difference in ANB values of the children approached the normal value of skeletal Class Ⅰ.Among them, the effect of skeletal Class Ⅱ children was more notable, which was statistically significant(P<0.05).The angle of the upper and lower anterior teeth reached the normal range after treatment, the increase of the anterior upper and lower anterior height makes the lower third of the face fuller, and the difference was statistically significant(P<0.05).Conclusion:The soft early appliance(LM-Dental)can effectively improve the degree of overjet and overbite of the anterior teeth through the treatment of skeletal Class Ⅰ and Class Ⅱ children, and appropriately promote the coordinated development of the maxilla and mandible.It may provide good foundation for children to enter the stage of permanent dentition.
