Pseudo Class III malocclusion is characterized by an anterior crossbite with functional forward mandibular displacement. Various appliances have been devised for early treatment of a pseudo Class III. The aim of this article is to highlight the method of construction and use a simple removable appliance termed as "Modified Hawleys appliance with inverted labial bow" to treat psuedo class III malocclusion in the mixed dentition period. It also emphasizes the importance of differentiating between true Class III and pseudo Class III. This appliance in this type of malocclusion enabled the correction of a dental malocclusion in a few months and therapeutic stability of a mesially positioned mandible encouraging favorable skeletal growth.
假性III类错牙合畸形的特征是前牙反牙合伴功能性下颌前移位。已经设计了各种矫治器用于假性III类错牙合畸形的早期治疗。本文的目的是强调一种简单可摘矫治器“带倒置唇弓的改良霍利矫治器”的制作方法和使用，以治疗混合牙列期的假性III类错牙合畸形。它还强调了区分真性III类错牙合畸形和假性III类错牙合畸形的重要性。这种矫治器在这类错牙合畸形中能够在几个月内矫正牙列不齐，并使近中移位的下颌骨获得治疗稳定性，促进有利的骨骼生长。
