All-ceramic crowns are composed entirely of porcelain and do not contain any metal. Aesthetics is the biggest advantage of all-ceramic crowns, while all-ceramic crowns are also highly biocompatible and do not interfere with magnetic resonance imaging. All-ceramic crown materials can be divided into glass ceramic, aluminum oxide, zirconium oxide, aluminum oxide all-ceramic crown costs$1,000, glass ceramic all-ceramic crowns for$1,500. At present, the main choice of all-ceramic crown material is zirconium dioxide, according to the different processing technology, the cost of domestic zirconium dioxide is 1,000 yuan, imported zirconium dioxide costs 2,000 yuan, and zirconium dioxide with automated-assisted design and fabrication costs more than 3,000 yuan.
