Metal blanks: the classic foundation of power in dental restoration

In the field of dental restoration that pursues high strength and durability, metal blanks, as traditional and reliable base materials, continue to play an irreplaceable role in the production of restorations such as crowns, bridges, and removable denture supports due to their unique mechanical properties and processing characteristics.

The core value of metal blanks lies in their excellent mechanical properties:

Ultra high strength and toughness: Metals such as cobalt chromium alloys, titanium alloys, and precious metal alloys have bending strength (up to 1400 MPa or more) and impact toughness far exceeding ceramics and resins. This endows the restoration with excellent anti fracture ability, especially suitable for thin and sturdy support structures of posterior long bridges, gap bridges, and removable dentures that can withstand tremendous chewing forces.

Excellent wear resistance: The metal surface has high hardness, which can effectively resist the wear caused by daily chewing, maintain the shape and functional integrity of the restoration for a long time, and extend its service life.

It has significant advantages in processing and application:

Precision adaptation and edge closure: Through casting or modern CAD/CAM cutting technology, the metal based crown/bridge can form a highly precise fit with the prepared tooth body, reducing the risk of micro leakage and providing stable support for the upper decorative porcelain or resin.
