In terms of permeability, all-ceramic crown is the first choice, but in terms of anterior tooth loss, zirconia crown bridge can only be used. The surface view of zirconia crown bridge is better than other crowns and bridges, but it is slightly inferior to all-ceramic crown (alumina).
If economic reasons are considered, the cobalt-chromium porcelain crown of the anterior teeth can also be made. Its comprehensive performance can not be distinguished from the appearance and color, but it is slightly irritating to the gums.
The clinical cost of cobalt-chromium porcelain crown is generally around 800, which is half of that of zirconia porcelain crown, so it can be considered.
