Thickness, strength, and plastic deformation of occlusal registration strips.

T he selection of an appropriate occlusal registration strip enables the dentist to work with precision and provides valuable information on occlusion. There are significant differences in the thickness, strength, and plastic deformation of the various articulating papers and occlusal registration strips. The patient’s perception of occlusal thickness ranges from 12.5 to 100 prn.“‘j The thickness of an occlusal registration strip should be below the patient’s perception. The purpose of this study was to determine the thickness, strength, and plastic deformation of selected occlusal registration strips and to list those registration strips that meet desirable standards.
