The use of rapid palatal expansion (RPE) escalates greatly in routine clinical practice. The most commonly recognized indication for rapid palatal expansion is the correction of a posterior crossbite. RPE is produced by applying a lateral force against the posterior maxillary dentition, producing a separation of the midpalatal suture and its remodeling. The clinical consequence of such a change is an increase in total arch length. That will allow the accommodation of impacted, rotated or displaced teeth into the dental arch. This additional arch length may lead to an overall reduction in the number of patients who undergo extraction due to tooth size-arch size discrepancies. RPE also can be used for preparation for functional jaw orthopedics or orthognathic surgery. Generally, RPE appliances are fixed and there are two types of expanders: the Haas-type and the Hyrax-type rapid palatal expanders. This clinical article presents three cases of rapid palatal expansion and their results.
在常规临床实践中，快速腭扩展（RPE）的应用大幅增加。快速腭扩展最常见的公认适应证是纠正后牙反合。快速腭扩展是通过对上颌后牙施加侧向力来实现的，从而导致腭中缝分离并重塑。这种变化的临床后果是牙弓总长度增加。这将使阻生、旋转或移位的牙齿能够排入牙弓。这种额外的牙弓长度可能会导致因牙量-骨量不调而接受拔牙的患者总数总体减少。快速腭扩展还可用于功能性颌骨矫形或正颌外科手术的术前准备。一般来说，快速腭扩展矫治器是固定的，有两种类型的扩弓器：哈斯型和Hyrax型快速腭扩弓器。本文介绍了三例快速腭扩展病例及其结果。
