Design of Customized Mouthguards with Superior Protection Using Digital-Based Technologies and Impact Tests

Dominique Pioletti, Naser Nasrollahzadeh Mamaghani, Martin Broome

Background In contact sports, an impact on the jaw can generate destructive stress on the tooth-bone system. Mouthguards can be beneficial in reducing the injury risk by changing the dynamics of the trauma. The material properties of mouthguards and their ...

Hybrid granular hydrogels: combining composites and microgels for extended ranges of material properties

Dominique Pioletti, Pierre-Etienne Bourban, Peyman Karami, Céline Samira Wyss

Developing hydrogels with optimal properties for specific applications is challenging as most of these properties, such as toughness, stiffness, swelling or deformability, are interrelated. The improvement of one property usually comes at the cost of anoth ...
