Abrasion Properties of Dental Zirconia and Enamel with Two Different Yttrium Oxide Contents

Increasing the amount of yttrium oxide can increase the transparency of zirconia material, improve its aesthetic properties as a restoration material. and whether it will change the microstructure and mechanical properties of zirconia porcelain and affect its friction and abrasion properties. It is worth studying.

The following conclusions can be reached through experiments:

1. The abrasion performance of two kinds of dental zirconia with different yttrium oxide contents are similar. Clinically, zirconia with higher transparency can be selected to increase the aesthetic effect of dental restoration.

2. Select the surface polishing treatment method to avoid abrasion of natural teeth. It is suggested that the grinding treatment of the restoration should be performed in the clinic to avoid abrasion on the natural teeth.
