Purpose To study the viscosities of eight interocclusal registration materials at 30 seconds after the start of mixing and to compare the time (Tcv) required for various interocclusal registration materials to reach a proposed critical viscosity of 5,000 poise. Materials and Methods One zinc‐oxide eugenol, one polyether, and six vinyl‐polysiloxane interocclusal registration materials were studied. The viscosities of the polymerizing materials were monitored with a cone and plate viscometer. Results One‐way analysis of variance showed significant difference in the viscosity at 30 seconds and in the Tcv among the materials. A zinc oxide eugenol interocclusal registration material was found to possess the lowest viscosity at 30 seconds and the longest Tcv. Conclusions The criteria for the selection of an interocclusal registration material should include its viscous properties because all materials behaved differently.
