摘要
腭扩展是正畸常用的矫治上颌横向发育不足及上颌牙弓狭窄的固定矫治技术。腭扩展分为快速腭扩展和慢速腭扩展,由于快速腭扩展矫治力较大,存在副作用,而慢速腭扩展可提供更接近生理性的力,严格掌握适应证,可取得较好的临床效果。本文就慢速腭扩展的矫治器类型、骨性和牙性改变以及与快速腭扩展的比较作一综述。
Palatal expansion is frequently applied in correction of maxillary transverse deficiency and upper dental arch constriction. Palatal expansion includes rapid palatal expansion and slow palatal expansion. Slow palatal expansion generated physiological expansion force compared to strong forces by rapid palatal expansion with some side effects. Satisfied clinical results will be achieved in selected cases. This paper reviews the types of appliance, skeletal and dental changes, and comparison with rapid palatal expansion.
