What are the materials for crown restoration?

Prosthetic crown materials are as follows:

All-zirconia porcelain, all-zirconia crown, all-alumina porcelain, all-cast porcelain, gold alloy porcelain, gold alloy casting, nickel-chromium alloy porcelain, nickel-chromium alloy casting.

It should be noted that the following prices do not include the post-core restoration costs of some teeth with large defects (ranging from 750- 1500).

Zirconia all-ceramic (6200 yuan): Zirconia is the hardest material among oral nonmetals at present. The advantages of this all-ceramic crown are that the inner crown contains no free metal components and has little stimulation to soft tissue; The processing technology is computer-aided cutting, which has high precision and good crown edge tightness; It has strong shading ability when it is used to repair some discolored anterior teeth and large area anterior teeth defects with metal post and core. The disadvantage is that the cost is higher.

All-zirconia crown (6200 yuan): When all-zirconia porcelain crown is applied to posterior teeth, the strength of surface decorative porcelain is relatively low, and there is a risk of porcelain collapse. At this time, you can choose a full zirconia crown, which can give consideration to strength and tissue compatibility, but the disadvantage is that the surface color is worse than that of ordinary decorative porcelain crowns, and the color is even, but at least it is white.

Alumina all-ceramic (5,400 yuan): The anterior teeth can be made of alumina all-ceramic material, which is not as irritating to soft tissues as 1, but it has worse shading ability than zirconia all-ceramic and cannot be applied to the anterior teeth of metal posts and cores. The machining process is also computer-aided cutting. But at present, it can only be sent to Sweden for internal crown processing, which takes a long time and can be used for more than a month at a time.

All-ceramic cast porcelain (5400 yuan): choose the crown material with the best aesthetic effect of the front teeth, with the best color matching and transparency. There is basically no stimulation to soft tissue. The first choice for cosmetic restoration of anterior teeth. But the color masking ability is poor, so it can not be applied to the anterior teeth of metal post and core.

Gold alloy porcelain (about 3800 yuan): it is a kind of metal porcelain crown, the inner crown is gold alloy and the outer crown is decorative porcelain. Can be used for any full crown restoration.

Gold alloy casting (about 2500 yuan): All-metal casting crown, this material is very suitable for teeth that cannot be seen by posterior teeth. All-metal crown has a small number of molars, and its hardness is closest to natural enamel. Long-term use will not cause wear of the opposite teeth. At the same time, gold alloy has little stimulation to soft tissue and high adhesion. Sturdy and durable, it is the first choice for the unsightly area of posterior teeth, with the highest cost performance.

Nickel-chromium alloy porcelain (840 yuan): It is a kind of metal porcelain crown. The inner crown is nickel-chromium alloy and the outer crown is decorative porcelain. It should be noted that this substance has a certain stimulating and staining effect on gums. It is reported in foreign literature that 10% people are allergic to nickel, which has been eliminated in foreign medical institutions and domestic clinics. The advantage is obvious: cheap.

Nickel-chromium alloy casting (460 yuan): Nickel-chromium alloy all-metal casting full crown is much harder than gold alloy full crown, which is not recommended when economic conditions permit.
