Correction of Class II malocclusion by distalization of maxillary molars with intraoral appliances is a non-extraction treatment approach, which has been described as an alternative to Head Gear. From the past few years, the procedures have undergone rectification to achieve treatment objective more precisely. This has been made possible by a better understanding of bone physiology, tooth movement, biomechanics and newer biomaterials. Nowadays newer distalizing appliances, like the Jones Jig, Lokar distalizer and Carrière distalizer, have been developed which have compact designs and cause minimal discomfort to the patient. Refinement in these appliances is concentrated mainly on achieving bodily movement of the molar rather than simple tipping. These appliances are also operator friendly as these are easy to insert and remove. The present case series presents the efficacy of these appliances in Class II malocclusion patients with a mean age of 16 years (age range of 15-17 years) that reported with the chief complaint of irregular upper front teeth, since non-extraction approach in correcting Class II malocclusion is gaining a lot of attention.
使用口内矫治器远中移动上颌磨牙来矫治安氏II类错牙合是一种非拔牙治疗方法,它被描述为头帽的替代方法。在过去几年中,这些治疗程序已经经过改进,以便更精确地实现治疗目标。这得益于对骨生理学、牙齿移动、生物力学和新型生物材料的更深入理解才得以实现。如今,已经开发出了更新型的远中移动矫治器,如琼斯矫治器、洛卡尔远中移动矫治器和卡里尔远中移动矫治器,它们设计紧凑,给患者带来的不适最小。这些矫治器的改进主要集中在实现磨牙的整体移动而非单纯倾斜。这些矫治器对操作者也很友好,因为它们易于插入和取出。本病例系列展示了这些矫治器在平均年龄为16岁(年龄范围为15 - 17岁)、主诉上前牙不齐的安氏II类错牙合患者中的疗效,因为非拔牙方法矫治安氏II类错牙合正受到广泛关注。
