Which Crown Material Is Better?

After a tooth is missing, we can do a implant restoration.

Dental implants are generally composed of three parts, the implant, the abutment, and the crown.

The vast majority of implants are composed of pure titanium, and a few are titanium alloys. The abutment in the middle is basically titanium.

Crowns located in the upper part are generally made of three materials, all-porcelain, metal and porcelain.

All-ceramic crown is now more popular, its aesthetic effect is the best, color, permeability compared with the other two better looking, CBCT, MRI no interference, for both to pay attention to functional recovery, but also to pay attention to the beautiful front teeth, the general doctor will recommend the use of all-porcelain crown.

Its disadvantage is also obvious, that is, the price is expensive. In addition, there are disadvantages such as poor ductility and large space required.

Metal crowns have better ductility and strength, and are generally used for posterior teeth, especially for posterior teeth when the tooth gap is relatively small and the vertical distance is relatively short, which is not enough to put all-porcelain crowns and porcelain crowns, metal crowns are safer. The downside is that it's not aesthetically pleasing.

The porcelain crown is between the all-porcelain crown and the metal crown, it is divided into two layers, the innermost layer is the metal layer, and the inner shell of the metal is sintered on the porcelain to form the outer porcelain layer. It is better than metal crowns in terms of aesthetics, but not as good as all-porcelain crowns, and cheaper in price than all-porcelain crowns, but more expensive than metal crowns. The difference from all-porcelain teeth is the material, and the metal ions in the metal base of porcelain teeth are easy to cause irritation to the tooth tissue, resulting in bleeding and shrinking gums; Oxidative deposits of metals form black lines of the gums.

When choosing a crown, it is recommended that you choose according to your own situation, and if you have the conditions, it is recommended to choose an all-porcelain crown, which will not be affected by uncontrollable factors in the future. And be sure to go to a regular professional dental hospital for treatment, so that there is a guarantee and no worries.
