材料和方法该技术涉及将速凝液体缓慢注入果冻或选定的组织中。在该工艺开发的早期阶段，熟石膏被注入果冻中，但当需要研究将此类材料注入动物组织的效果时，需要在强酸或碱性溶液中煮沸样本以去除组织，因此有必要使用速凝牙科塑料。该装置由一个装有果冻的烧杯组成，烧杯上支撑着一个装有熟石膏的大型皮下注射器（图 1）。将牙科塑料注射到组织中是用较小的一次性注射器以正常方式进行的。
MATERIALS AND METHODSThe technique involves the slow injection of a quick-setting fluid into a jelly or into the selected tissue. In the early stages of the development of the process, plaster of Paris was injected into table jellies, but when it was desired to study the effect of injecting such materials into animal tissue the need to boil the specimen in strong acid or alkaline solutions to remove the tissue made it necessary to use quick-setting dental plastics instead. The apparatus consists of a beaker that contains the jelly over which is supported a large hypodermic syringe that contains the plaster of Paris (fig. 1). The injections of dental plastic into tissue were made from smaller disposable syringes in the normal manner.
