The use of a simple technique with an inexpensive syringe loaded with heavy-body tray material resulted in a savings of preparation time and storage space in the conditioning unit. Only one type of material needs to be liquefied. The use of the heavy-body material in syringe and tray in conjunction with a hydrophilic technique have practically eliminated the annoying problem of tearing of the material in the gingival crevice on removal of the impression. Moisture control is no longer an aggravating problem.
使用一种简单的技术，即使用装有重体托盘材料的廉价注射器，可节省调拌单元中的制备时间和存储空间。只需将一种材料液化。在注射器和托盘中使用重体材料并结合亲水性技术，实际上消除了取下印模时材料在龈沟内撕裂这一恼人的问题。湿度控制也不再是一个棘手的问题。
