Malocclusion is caused by an incorrect relationship between the teeth and jaws, which leads to an abnormal variation of normal occlusion. Crowding is an increasingly common type of malocclusion caused by a discrepancy in tooth-jaw size that leads to twisted and misaligned teeth. Two methods to treat this malalignment are tooth material reduction and arch width expansion. Of these two treatment options, the latter is preferred because it enables orthodontists to avoid extractions and increase the dental arch perimeter by widening the jaws; this resolves crowding and accommodates existing teeth. This case report describes a unique approach in the treatment of a patient with severe crowding by an orthopaedic widening of the dental arches using a skeletally anchored rapid palatal expander. Under favorable circumstances, this approach can serve as a robust method to treat patients with severe crowding and may be used as an alternative to extraction.
错牙合畸形是由牙齿与颌骨之间的不正确关系引起的，这会导致正常咬合出现异常变化。牙列拥挤是一种越来越常见的错牙合畸形类型，它是由牙颌大小差异导致牙齿扭曲和排列不齐引起的。治疗这种牙齿排列不齐的两种方法是减少牙齿材料和扩大牙弓宽度。在这两种治疗选择中，后者更受青睐，因为它能使正畸医生避免拔牙，并通过扩大颌骨来增加牙弓周长；这解决了牙列拥挤问题并容纳了现有的牙齿。本病例报告描述了一种独特的方法，即使用骨骼锚固快速腭扩展器通过正畸扩大牙弓来治疗严重牙列拥挤的患者。在有利的情况下，这种方法可以作为治疗严重牙列拥挤患者的一种有效方法，并且可以用作拔牙的替代方法。
