This article highlights the use of two new design space regainers--the "lingual arch crossbow" and the "double-banded space regainer." The former may be used for distalizing a mesially migrated mandibular first premolar, if it erupts prior to the canine. The latter may be used in conventional cases of interdental space loss. They both contain assemblies that function through the action of NiTi open coil springs.
本文重点介绍了两种新型间隙保持器——“舌弓十字弓”和“双带环间隙保持器”。如果下颌第一前磨牙在尖牙之前萌出,前者可用于将近中移位的下颌第一前磨牙远中移动。后者可用于牙间隙丧失的常规病例。它们都包含通过镍钛开口螺旋弹簧作用发挥功能的组件。
