隐形功能矫治在青少年骨性Ⅱ类下颌后缩患者治疗中的研究进展

Research progress in functional clear aligners to treat teenagers with skeletal classⅡmandibular retraction patients

青少年骨性Ⅱ类错畸形在正畸临床中常见,其发病率高,对美观和功能影响较大。骨性Ⅱ类患者在临床中常表现为上颌前突、下颌后缩等矢状向发育异常,大部分学者认为矫治下颌后缩的最佳时机是在生长发育高峰期。随着隐形矫治技术的快速发展,隐形功能矫治技术应运而生,该技术将传统的双期矫治合二为一,在前导下颌的同时排齐牙列、协调牙弓,提高了矫治效率,扩大了隐形矫治的适应范围。本文就青少年骨性Ⅱ类患者生长发育特征和隐形功能矫治技术治疗青春期骨性Ⅱ类患者特点进行讨论,以便正畸医师更好地为此类患者进行诊疗。

Adolescents with skeletal classⅡmalocclusion are frequently seen in orthodontic departments,with a high occurrence rate and significant effects on both appearance and function.Maxillary protrusion and mandibular retrusion are frequently demonstrated in skeletal classⅡmalocclusion.Most experts agree that the ideal period to correct mandibular retraction is an adolescent growth spurt.With the rapid development of clear aligner technology,functional clear aligner technology has emerged,which combines the traditional two-stage orthodontic corrections into one,and helps expand the scope of Invisalign.It can align the teeth and coordinate dental arches while guiding the mandible forward,reduce orthodontic time,and greatly improve orthodontic efficiency.This article aimed to explore the growth and development characteristics as well as the features of clear aligners in the treatment of teenagers with skeletal classⅡmalocclusion.
