The Department of Biomedical Materials Science offices and laboratories occupy nearly 5,000 square feet within the School of Dentistry. These facilities permit research and characterization of a diverse range of materials (metals, polymers, ceramics, composites), of a wide range of properties (physical, mechanical, electrochemical, biological, etc.), and at all levels of interest - from atomistic to macroscopic.
In light of the fact that the equipment available in our laboratories represents the state of the art in material testing and characterization, and a variety of industries and other universities have requested access to this equipment, the Department of Biomedical Materials Science has formalized a Shared Equipment Facility This facility provides access to equipment used to perform materials processing, characterization and certification.
These services are now available to users within and outside the academic community on a fee-for-service basis. Users may become trained in the use of the equipment and be allowed independent operation or testing may be performed by departmental personnel at an additional cost.
For more information, refer to the Shared Equipment Facility Catalog.
The ceramic processing laboratory contains the equipment typically found in a dental laboratory and allows the fabrication of a variety of all-ceramic prostheses (powder porcelain, pressable, glass-infiltrated, CAD-CAM, and sintered). Some of the techniques, such as lost wax method and air abrasion, are also useful in preparation or surface treatment of metallic and other materials for a variety of applications.

Our Dell Precision T7400 graphics workstation (dual quad-core processors, 32GB RAM, 2TB HD, 512MB graphics accelerator) is a powerful platform for several finite element modeling packages. Mimics software can convert 3D models captured by our micro-CT scanner, as well as a variety of medical scanners into finite element models suitable for export to Abacus or ANSYS. Abacus software can predict the mechanically and thermally induced stress and microstrain distributions in a component or surrounding an implant. The necessary material elasticity constants are determined using our ultrasonic pulse apparatus and analytical balance. Fe-safe software works in conjunction with Abacus to predict fatigue lifetimes of components.
ALTA Pro software can analyze accelerated lifetime test data to predict product reliability and can perform Monte Carlo simulations to design more efficient fatigue tests.
