Early orthodontic interventions are often initiated in the developing dentition to promote favorable developmental changes. Interceptive orthodontic can eliminate or reduce the severity of a developing malocclusion, the complexity of orthodontic treatment, overall treatment time and cost. Premature loss of deciduous tooth or teeth can often destroy the integrity of normal occlusion. There are many space regaining and maintaining devices mentioned in literature. In this article, I present a simple space regaining method by a piece of nickel titanium (NiTi) wire bonded between the teeth in active loop form, and the unique shape memory property of NiTi wire will upright or move the teeth and the lost space can be regained easily.
早期正畸干预通常在牙列发育阶段开始，以促进有利的发育变化。阻断性正畸可以消除或减轻正在形成的错牙合畸形的严重程度、正畸治疗的复杂性、总体治疗时间和成本。乳牙过早缺失往往会破坏正常咬合的完整性。文献中提到了许多间隙恢复和保持装置。在本文中，我介绍一种简单的间隙恢复方法，即用一段镍钛（NiTi）丝以活动曲的形式粘结在牙齿之间，NiTi丝独特的形状记忆特性会使牙齿直立或移动，从而可以轻松恢复缺失的间隙。
