What's the difference between 3y, 4y, and 5y Zirconia?
The terms 3Y,4Y, and 5Y zirconia are becoming more prevalent in today's dental world.
The Y in the descriptor refers to "Yitria" which is part of what zirconia consists of.
In laymen's terms, the more Yitria the zirconia contains, the more translucent the crown will be. Adversely, the more Yitria the crown contains, the less flexural strength the crown has. Below are Great Impressions Dental Lab's 3y, 4y, and 5y options:
