NYU College of Dentistry's Dr. Yu Zhang receives $3.7M in grants: 5 things to know

New York City-based NYU College of Dentistry's Yu Zhang, PhD, received two grants from the National Institute of Dental and Craniofacial Research, totally $3.7 million.

Here are five things to know:

1. The grants will support research to develop improved materials for restorative dentistry that are both resilient and aesthetically pleasing. Dr. Zhang, a professor of biomaterials, will lead the two projects.

2. One of the five year grants will focus on developing zirconia-based ceramics that are strong and translucent. Zirconia-based ceramics are often strong, but have poor translucency.

3. Dr. Zhang is dedicating $1.8 million to help develop translucent and strong ceramics for better performing restorative materials. The research aims to extend clinical indications for zirconia to the aesthetic realm and has applications for minimally invasive treatments.

4. The second grant will focus on improving the fracture resistance of porcelain-veneered dental prostheses, including crowns and bridges. Dental crowns and bridges are usually constructed by applying an aesthetic porcelain veneer, which makes it look more natural, to a strong core. However, this process leads to chipping and fractures.

5. Dr. Zhang aims to improve the fracture resistance of porcelain-veneered prostheses through reducing residual tensile stresses in conjunction with designing a veneer interface that is continuously graded rather than two separated layers.
