TECHNOLOGY ASSESSMENT & TRANSFER, INC — Department of Health and Human Services SBIR Phase I: 100

Description

DESCRIPTION provided by applicant In this Phase I SBIR project Technology Assessment andamp Transfer Inc TAandamp T and their collaborator propose development of ceramic additive manufacturing aka D printing for production of high performance ceramic dental restorations in the dental laboratory environment A ceramic additive manufacturing approach to fabricating dental restorations has the potential to lower material and processing costs as well as improve restoration aesthetics and performance resulting from the D spatial control of material deposition The two aims for this Phase I program are to demonstrate that material properties comparable to commercial restoration material can be achieved using ceramic additive manufacturing and to demonstrate dimensional accuracy and fit comparable to current restorations These aims will be achieved by engineering ceramic particle size distribution and developing firing protocols to achieve desired material properties and to optimize additive manufacturing process parameters to achieve dimensional accuracy as verified by D scanning and fit testing PUBLIC HEALTH RELEVANCE Technology Assessment andamp Transfer Inc TAandamp T proposes development of a ceramic additive manufacturing aka D printing process for production of high performance ceramic dental restorations Compared to CAD CAM technology currently in use an additive manufacturing approach enables lower material costs and processing costs less material wastage batch processing is possible and improved aesthetics and mechanical properties through D spatial control during fabrication
