Retaining tooth positions after orthodontic space closure in cases with multiple spacing of anterior teeth are illustrated by selected cases with varying degrees of bimaxillary spacing initially (Figs. 1-6). In each case, bonded lingual retainers which allowed physiologic tooth movements were used with encouraging results. A meticulous technique for fabrication and bonding of flexible spiral wire retainers is mandatory for clinical success. Detailed recommendations are presented. If similar trials by others confirm the durability and effectiveness of acid-etched lingual retainers, it is expected that the technique can be recommended for routine clinical application.
通过最初具有不同程度双颌牙间隙的选定病例，展示了前牙多间隙病例正畸关闭间隙后的牙齿位置保持情况（图1 - 6）。在每个病例中，使用了允许生理性牙齿移动的粘结舌侧保持器，结果令人鼓舞。临床成功的关键在于精心制作和粘结柔性螺旋丝保持器的技术。文中给出了详细建议。如果其他人的类似试验证实了酸蚀舌侧保持器的耐用性和有效性，预计该技术可被推荐用于常规临床应用。
