Layers of illusion

Lecture Description: 

Complexity of natural dentition has presented challenges for dental technicians to match the shade, form, surface details, and translucency. Limitations of ceramic materials, space, and capability of manipulating ceramic materials deepen the challenges. This presentation will focus on how to use multilayer porcelain technique to match shade and translucency. Specific attention will be given to building the various layers of ceramic that allow the development of optical properties in the final restorations that mimic natural teeth. Short videos of layering technique will be featured. The finishing techniques including contour, texture, surface colorants, glaze, and polishing are equally critical to the success of recreating a natural appearance and will be presented in details.
