Don't know much about cases back in China. However, the best option for front teeth would be all porcelain veneers or all porcelain crowns. This way you won't have allergic/toxic reactions to some of the metals in the normal porcealin-fused-to-metal (PFMs) and you won't have a dark/blue shadow along the gum later on.
Good luck.
