SpaceDent Exhibit Now Part of the Permanent Exhibition at the Noordung Center

The exhibit showcases a research module simulating a simplified dental clinic environment, equipped with specially adapted dental instruments, a dental manikin, and purpose-built filtration and electrical systems specifically engineered to function reliably under conditions of microgravity and hypergravity. The project marks a significant milestone in the development of space dentistry, addressing the challenges of long-duration missions to the Moon and Mars.

The SpaceDent project, designed and carried out by students of dental medicine, mechanical engineering, and electrical engineering at the University of Ljubljana, tested how to safely perform dental procedures in microgravity during the 83rd ESA parabolic flight campaign. During 90 parabolas with 22-second microgravity intervals, two dentistry students performed the first simulated caries preparation and composite restoration procedures in weightlessness. These procedures were performed on a dental manikin’s artificial teeth. The procedures were conducted in a specially designed enclosed environment that contained waste particles and prevented interference with other experiments on board the aircraft. The results of the study showed that, in microgravity, sufficient control can be maintained for the safe execution of dental procedures, opening the door to expanding the scope of medical and surgical interventions feasible in space.

"The members of the SpaceDent project team are deeply honored and sincerely grateful that our exhibit has become part of the permanent exhibition at the Herman Potočnik Noordung Space Technology Center. Being featured in such a significant national institution sends an encouraging message to all Slovenian students – to boldly embark on the path of space exploration, knowing that their contributions are recognized, valued, and an important part of both Slovenian and European space progress. We extend our gratitude to the Noordung Center team for their kindness and the opportunity to preserve our story in the home of Slovenian space heritage." said project members Tine Šefic and Hana Prtenjak. 

"The SpaceDent exhibit is an outstanding example of Slovenian innovation, expertise, and interdisciplinary collaboration. By including it in our permanent exhibition, we aim to bring the realities of space missions closer to our visitors and highlight the importance of preparing for medical care in space. At the same time, we hope to inspire young people to boldly shape the future of space exploration," said Neža Pavlič Brečko, Director of the Noordung Center

The permanent installation of the SpaceDent exhibit at the Noordung Center offers visitors a compelling insight into a major achievement by Slovenian students, featuring a research structure specifically designed for experiments conducted during parabolic flight. It also underscores the value of interdisciplinary collaboration between medical and technical sciences. At the same time, the exhibit helps raise awareness about the need to prepare for the medical realities of future space missions and supports the development of solutions that can enhance healthcare delivery on Earth – particularly in remote environments.
