Services of the Research Center

The University of Zagreb School of Dental Medicine plans to offer the following research infrastructure services through its Research, Innovation and Science Center:

Contracted R&D

Our scientists can carry out R&D projects for dental materials on behalf of companies. Our experts are skilled in designing custom composite materials for various purposes and in characterizing physical and chemical changes under conditions similar to the oral cavity, already at the in vitro stage.

Methodology: per the Center's list of methods, as needed for the service
Price: on request
Research and DevelopmentOrder service

Analytical Services

The research infrastructure can be used for data collection, analysis, testing, or professional training for companies.

Methodology: per the Center's list of methods, as needed for the service

Analysis and TestingOrder service

Access to Infrastructure

Certain devices within the infrastructure are highly sophisticated and require experienced, trained users. Access is therefore available at a fixed hourly/daily rate, but only for experienced scientists and under the supervision of trained staff of the Zagreb School of Dental Medicine.

Subject of Scientific Testing

The following products may be subject to scientific testing:

commercial composite restorative materials
experimental/laboratory composite materials
ion-releasing composite materials
pit and fissure sealants
composite cements
orthodontic cements
3D-printed inlays, onlays, overlays, or crowns
orthodontic aligners
dental light-curing units
3D printers
beverages (natural or sweetened juices, etc.)
food products with artificial sweeteners
toothpastes
mouthwashes
dental varnishes, etc.

Processes Studied by Scientists at the School of Dental Medicine

Industrial processes studied by scientists at the School of Dental Medicine include:

idea discovery / front-end innovation
development of new products (composites, cements, 3D-printed materials) at laboratory level
material characterization
degree of conversion and polymerization kinetics
mechanical properties
ion-release measurements
quality control of composites under aging and material degradation protocols
quality control of changes in optical properties (light transmittance, color, color change)
quality control of tooth structure or materials under the influence of food, beverages, toothpaste, mouth rinses, and varnishes
quality control of light-curing units for composite materials
compliance with regulations for composite materials

Methods Used by the School of Dental Medicine

The methods used by the School of Dental Medicine in its work, which it can offer within the scope of the DIGIT project, are:

expertise and proprietary material-mixing procedures (asymmetric centrifugal mixer / vacuum)
real-time Fourier-transform infrared spectrometry
visible-light spectrometry
chemical surface mapping
pH measurements
microhardness measurement
flexural property measurement
in vitro aging simulation
in vitro color change
NIST-referenced real-time light intensity measurements and spectral characterization
real-time temperature changes
database of degree of conversion and mechanical properties for composite materials
clinical trials

Composite materials are the most commonly used dental restorative materials today. There is growing interest in developing bioactive composite materials that prevent secondary caries through ion release. This has been the main focus of experts at the Research, Innovation and Science Center for the past 20 years.
