Olivier Tric, MDT, addresses his criteria for material selection and focuses particularly on the advantages and the application of LiSi ceramic and its ingots. Through a variety of clinical cases, he illustrates how to control the physical properties of the material in both simple and complex situations; such techniques offer optimal strength while protecting the opposing natural dentition. Tric also demonstrates how to control the optical properties of restorations through intricate layering resulting in highly esthetic outcomes to mimic the beauty of nature.
