Sažetak
The practical procedure w ith HM and Ex-3-N materials is presented and ali phases of the positional, functional impression and the lining of the prosthetic base are described. Particular emphasis is placed on delicate and im po rtan t interventions. Apart fro m theoretical instruction these materials require a course of object dem onstration. These instructions are therefore only a reminder for the prosthodontists who were previously acquainted w ith this method. In the chapter »Critical Review« some specificities of this method are mentioned in the form of a discussion. Particular importance is ascribed to the systematical recording of the positional, functional impression and also to the recordings made on the positional and working model. Correctm arking is essential fo r the individual impression spoon which is the key problem in the manufacture of the total prosthetic base since the way in which the edges o f the prosthesis behave towards active and passive tissues depend on it.
The folds o f the mucosa must be assessed according to their dynamics in relation to the edges of the prosthetic base. But the dynamic value of the folds is very different. The destabilization effect
of the fold cannot be assessed visuaIly but shows on the positional impression made w ith the HM substance. It ought to be emphasized that good results depend m ostly on careful w o rk in the laboratory.
The en tire work is the result of great practical experience and confirms the belief that these materials make possible a higher percentage of successful interventions.
