Clinical Survival of Reduced-Thickness Monolithic Lithium-Disilicate Crowns: A 3-Year Randomized Controlled Trial.

Objectives: The aim of this randomized controlled trial was to see if the minimally invasive approach (reduced restoration thickness) would result in good clinical success of monolithic ceramic crowns compared to conventional layered all-ceramic crowns, and thus be an alternative to conventional tooth preparation.

Materials And Methods: The ceramic that was investigated was IPS e.max lithium-disilicate ceramic produced using two different processing methods.

New Knowledge about Zirconium-Ceramic as a Structural Material in Fixed Prosthodontics.

Dental ceramics represents a major structural material in fixed prosthodontics. Increasing demands for esthetics led to development of new ceramic materials in order to eliminate the use of metal framework and for all ceramic restorations with mechanical properties to withstand high occlusal forces. Out of all the present ceramic materials, zirconium-ceramic has the best mechanical properties, and is the only material that can be used for longer span fixed dental restorations.
