Early advances in resin-based materials broadened their use to direct posterior restorations. Conventional composite resin restorations (designed to be placed in 2mm increments) are subject to problems associated with polymerization contraction, which may generate microfiltration, air trapped between layers, and cuspal deflection.

Nowadays, photography is becoming more powerful in dentistry and dentists
are trying so hard to take good pictures for different purposes. For that reason a

Zirconia: the Future of Aesthetic Indirect Restorative Dentistry
Current dental all-ceramic systems can be classified into three categories: porcelains, glass ceramics (such as lithium disilicate), and polycrystalline ceramics (such as zirconia and alumina).
Can I sharpen Sharp Diamond instruments?
No, Sharp Diamond instruments cannot be sharpened. The tip’s resistance to wear is based on an extremely durable metal alloy and the micro membrane coating that protects it. Sharpening removes the protective coating and weakens the tip, and thus, the functionality of the instrument is weakened.
