Dental inlays are divided into ordinary inlays and high inlays, they are not charged according to the shape, but mainly according to the inlay material, for resin inlays, the charge is usually around$900. Polymer porcelain inlays, which are a type of porcelain, but are actually a type of resin, are charged at around$1500. There are also glass-ceramic inlays, which cost around$2500-3000. For zirconium dioxide inlays, the cost may be slightly higher, at$3600 or more. For inlays we have to choose the right material for ourselves, like resin inlays or polymeric porcelain inlays, which generally have a life span of about 3-5 years and are not as wear resistant. For glass-ceramic inlays, it is very wear-resistant and strong enough, but when used for posterior teeth, it is likely to be unable to withstand too much biting force, which will easily lead to the chipping of the inlay. Zirconia inlays are expected to be in the mouth for a long time, because the bonding technology is not too good, which can easily lead to the loss of zirconia inlays.
