Development of Dental Glass Polyakenoate Cements suitable as Restorative in stress Bearing Areas based on identification of Material Properties

Objective



In the last years, a public debate has arisen on the health hazard of amalgam as a tooth filling. In turn, the demand for substitutes has increased, and new dental composites are being developed. However, during the polymerization process, these materials are shrinking, which may lead to crack growth. The consequence is a bad adhesion to the tooth, so that the filling cannot accomplish its purpose. Up to now, the suitability of new filling materials has to be examined in expensive and extensive clinica1 tests. The aim of this research project is to develop procedures to evaluate the suitability at an earlier stage, so that the immense expenses for clinical tests can be decreased greatly. For this purpose, the material behaviour during the polymerization process has to be modelled, so that simulative studies can be performed. Simultaneously, sophistiicated experimental investigations have to be performed, in order to determine the characteristic material parameters correctly.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Call for proposal

Procedure for inviting applicants to submit project proposals, with the aim of receiving EU funding.
