Research activity

The activity of the Dental Biomaterials Laboratory (DeBioLab) is one of the main aspects of the teaching & research program of the Dental Clinic of the University of Trieste. The laboratory is equipped with new and innovative instrumentations and technologies to investigate and characterize polymeric-, metal- and ceramic-based biomaterials. This is a very suitable place for all students of the Dental School and of the Dental Hygiene School to prepare the experimental part of their final thesis.

The daily activity of researchers, Post-graduate, Master and graduates students results in the publication of different research studies every year in prestigious peer-reviewed international scientific journals.

The researches conducted in the laboratory represent an important aspect of the curriculum vitae of the students of the Dental School. Important collaboration with prestigious Universities are currently ongoing.

Many consultancies have been done for the major international companies operating in the dental materials field. Collaborations rely on the characterization of innovative materials, before the market incoming.
