In Part III of our program, Dr. Boksman discusses the rationale for using a technique specific PVS material for dual arch impressions that is extremely stiff. Do you need a PVS adhesive with your impressions? If you refrigerate your PVS to increase the working time you may be introducing variables that affect your final prostheses. The rationale for an all in one impression versus a putty wash is discussed. Putty reduction guides can help refine preparations and a simple method of fabrication is presented. What is critical to all clinicians is the fact that a PVS bite registration material does not fit on a stone model derived from alginate – there is a solution.
