The influence of undercut depths on the accuracy of casts poured from irreversible hydrocolloid impression materials

Objectives: To evaluate the elastic recovery of a typical irreversible hydrocolloid impression material in terms of the amount of undercut identified and additional thickness of spacer provided before custom tray fabrication. Methods: This study surveyed the undercut depths of the teeth surfaces and...
