A Preliminary Study on the Accuracy of Cast Metal Removable Partial Denture Frameworks Produced from Wax, Printed, and Milled Patterns.

Purpose: To compare the accuracy of two digital workflows for producing resin patterns to be cast into metal frameworks compared to an identical framework manufactured conventionally from a wax pattern.

Materials And Methods: Nine casts were duplicated from a maxillary master cast of a partially edentulous arch. Their accuracy was determined by measuring the same points in two and three dimensions using a reflex microscope, which was also used to measure all frameworks to an accuracy of 4 μm.

Viability of Candida albicans in Denture Base Resin After Disinfection: A Preliminary Study.

Purpose: To quantify the depth of penetration of Candida albicans (C albicans) into a denture base resin and to investigate its viability after disinfection.

Materials And Methods: Heat-polymerizing polymethyl methacrylate plates were contaminated with C albicans, then washed, dried, and prepared for scanning electron microscopy (SEM). Vertical surfaces were cut, and the depth of any penetration was measured.
