Russell A. Giordano II

Research Interests

Fabrication of multiple phase interpenetrating ceramic composites.This research involves the infusion of various types porous ceramic matrices with resins, glasses and metals to fabricate materials for CAD-CAM machining systems as well as novel medical and dental implant devices.

Effects of machining and polishing conditions on ceramic materials. Research has involved the analysis of residual stress development as well as strength alteration due to machining and polishing. Milling devices such as the CEREC 2 (CAD-CAM device) as well as the Celay (manual copy milling) have been used to fabricate test specimens from a variety of ceramic materials. These conditions have been compared to controlled sequential machining and polishing to analyze the effects of milling tools, load, solutions, and devices on ceramics.

New Materials Analysis. Many new materials are introduced to the dental community each year. A number of our projects involve characterization and analysis of mechanical, physical and chemical properties of ceramic, composite resin and metal restorative systems.

About Dr. Giordano

Dr. Giordano is currently Professor, Director, and Assistant Dean of Biomaterials and Biomaterials Research with a joint appointment as a Professor in the Division of Materials Science and Engineering. His research has been focused on solving clinical needs and is thus primarily applied or translational research. He has been the primary mentor for over 200 students in various research projects including composite resins, ceramics, adhesives, endodontic and orthodontic materials, tissue matrix devices, machining materials and devices, polymer and ceramic 3D printing, and remineralization. Dr. Giordano developed an interpenetrating phase ceramic combining a ceramic matrix with a polymer second phase that was licensed from Boston University and commercially developed into a dental product called Enamic for single-visit machined restorations.

Dr. Giordano is active in the development of US and International standards for dental materials. He serves as the chair of the ADA CAD/CAM Consensus Body for machinable materials, chair of working group 2.2 on ceramic materials, and the associate chairman for prosthodontic materials. On the International level, he has served as the Head of the Delegation on Prosthodontic Materials as well as the U.S. expert on dental ceramics and polymer restorations to the International Standards Organization TC 106.
