Pressure distribution using tissue conditioners on simplified edentulous ridge models. Part 2: The influence of the powder particle size and ethanol content.

The distribution of pressure changes over time at the denture periphery and the residual ridge crest were measured to evaluate the influence of powder particle size and ethanol content in liquid of tissue conditioners used for a dynamic impression technique. The study suggested that the shrinkage of tissue conditioners over time influenced the adaptation at the denture periphery when the components of tissue conditioners were varied for use as a dynamic impression material.
