The difference between the three is that:
1. zirconia all-ceramic teeth: among the three kinds of all-ceramic teeth, zirconia all-ceramic teeth are the strongest dental restorations, so they are not easy to break when used in dental restoration. They can be used for single crown restoration of a single tooth or multi-crown restoration.
2, cast porcelain teeth: cast porcelain is not suitable for the restoration of continuous crowns, only suitable for the restoration of single crown teeth, its light transmittance is better, so it is not suitable for the restoration of severely discolored teeth.
3. Alumina all-ceramic teeth: They also have the advantages of all-ceramic teeth, but they are poor in hardness, easy to collapse and short in service life, and have been eliminated (at least the processing factory we cooperate with has stopped making them).
As for the difference between Adit made in China, Willard made in Germany and Lava made in the United States, the compressive strength is mainly about 600- 1000 MPa, Willard1000-1300 MPa and Lava 1600-2000 MPa.
The difference between porcelain teeth and all-ceramic teeth can be understood by a picture:
