Rapid Assessment of Dental Polymers Using Gradient Samples



Nancy J. Lin, Peter Drzal, Sheng Lin-Gibson


Dental composites are widely used yet still face challenges including incomplete conversion, polymerization shrinkage, and poor adhesion to tooth structures. High-throughput techniques to quickly assess several material properties in a combinatorial manner would prove useful in selecting candidate materials for further testing in the clinic. The twofold purpose of this study was (1) to fabricate well-controlled polymer substrates with a range of compositions and material properties, and (2) to develop techniques to measure these properties. Samples were prepared with variation in both composition and degree of conversion, and the resulting chemical, mechanical, and biological properties were evaluated. These techniques could easily be applied to novel materials to support dental materials research and accelerate improvements in clinical products.
