Abstract

The interest of dental research in metal-free restorations has been increasing in the past 20 years following the introduction of innovative all-ceramic materials into daily practice. In particular, high-strength ceramics have widely increased the clinical indications of metal-free prostheses, showing more favorable mechanical characteristics compared to the early ceramic materials (Zarone et al., 2011). During the past decade, new dental ceramic materials, such as glass ceramics, polycrystalline alumina, and zirconia-based ceramics, have been successfully introduced into the clinic, along with new processing technology, ...
