ntroduction: The main consequence of not treating tooth decay in time is the total or partial loss of the tooth. One of the alternatives to replace the lost tooth and return the functions is through fixed prostheses. Today there are 3 generations of yttrium-stabilized zirconium polycrystals (Y-TZP). Seeing that in the third Generation the yttrium content was increased to approximately 5% in moles (5Y), stabilizing the materials approximately 50% of cubic phase and 50% of tetragonal phase, thus giving a translucent zirconium (5Y) with a high aesthetics and greater naturalness to the dental crown. Objective: To identify the different optical and mechanical properties of translucent zirconium compared to other restorative materials used in fixed prostheses. Materials and methods: This narrative review evaluated 115 scientific articles from the Medline information sources (via PubMed), Scien...
