| Abstract Scope |
With rapid advances in material development and digital technology, time efficiency of dental workflow and fit accuracy of ceramic restorations are ever improving. Zirconia and lithia glass–ceramics are at the forefront of this advance. The trend in fabrication is to move from CAD/CAM grinding partially sintered/crystallized blocks to fully sintered/crystallized materials, thereby circumventing the need for post-machining heat treatment; or to drastically reduce the ceramic sintering time. In these endeavors, a better understanding of ceramic properties and innovative ductile-regime grinding (shaping) and ultrafast sintering (densification) technologies is paramount. Examples of enhancing ceramic fracture resistance through novel biomimetic designs are also given. Challenges facing the implementation of new technologies in the efficient development and production of high quality dental ceramic prostheses will be addressed. |
