A one-session technique for preparing a temporary space maintainer has been described. The technique consists of attaching an acrylic resin pontic to etched surfaces of natural adjacent teeth by means of a composite resin. The main advantages of this technique are elimination of premature tooth preparation, good esthetics, fair strength, low cost, and rapid completion of the restoration without the need of a dental laboratory.
一种制备临时间隙保持器的单次就诊技术已被描述。该技术包括通过复合树脂将丙烯酸树脂桥体附着到相邻天然牙的蚀刻表面。此技术的主要优点是无需过早进行牙齿预备、美观性好、强度尚可、成本低，且无需牙科实验室即可快速完成修复。
