Double Monolithic Protocol: The Solution to Fluorescence Limitations

Abstract

Objective: The present paper aims to demonstrate the incorporation of the double monolithic protocol (DMP) into a chairside digital workflow to reproduce the fluorescence properties of natural teeth with chairside monolithic restorations when exposed to different light sources. Clinical Considerations: A female patient reporting dissatisfaction with her upper anterior teeth was rehabilitated using seven veneers and a three-element bridge. The DMP was applied to the bridge, which consisted of a primary lithium disilicate framework to which leucite-reinforced glass ceramic veneers were cemented. The fluorescence of the different substrates and ceramic restorations was evaluated throughout the rehabilitation process, under 365 and 405 nm light. Conclusions: The DMP allows chairside procedures to be optimized by achieving predictable, mechanically resistant, and esthetic restorations. Clinical Significance: The DMP is a new chairside solution for developing ceramic restorations with optimal esthetics and combined mechanical properties, eliminating the need for sintering or glazing procedures.
