Biomaterials at Nebraska

Our section teaches biomaterials courses in restorative dentistry, conducts biomaterials research, and participates in graduate degree programs affiliated with the UNMC Oral Biology Department and the UN-L College of Engineering and Technology. Including dual-trained faculty housed in the Operative Dentistry and Prosthodontic Sections, the Biomaterials Section is supported by six full-time faculty, one research technologist, one graduate student and part-time student researchers from the UN-L biomedical engineering program. In collaboration with faculty from other departments and universities, our research efforts are focused on the development of various dental and maxillofacial materials, the study of TMJ disc mechanics, and cartilage tissue engineering.

Biomaterials Research

The Biomaterials section oversees the Biomaterials laboratory, which is housed in a recently remodeled research wing and supports both faculty and student research projects. Nearby laboratories include those focusing in biophysics, neuropharmacology and cellular signaling pathways. As a participant in the Biomaterials and Biomechanics Focus Group, research is conducted in collaboration with investigators from the Growth and Development and Oral Biology departments. In addition, dental biomaterials are clinically evaluated in the Cruzan Center, Research is conducted on dental resin-based composites, cements, maxillofacial prosthetic materials, TMJ disc dynamics, cartilage failure mechanisms and cartilage tissue engineering. Recent outside collaborators include scientists from the University of Missouri, Creighton University, Purdue University, Rensselaer Polytechnic Institute and the University of Zurich. Recent corporate sponsors include Cook Biotech, Inc., and G.C. America Corp.
