GENEVA, Switzerland: Dental restorations often rely on CAD/CAM resin composites for their precision and reliability. However, ensuring the longevity and durability of these restorations remains a challenge. The integration of bidirectional E-glass fibres beneath the composites offers potential benefits in enhancing fracture resistance and directing crack propagation, thus potentially minimising catastrophic failures. A recent study has delved into understanding these dynamics further, finding that the exact placement of fibre layers under the composites needs consideration in order to balance resistance and risk of catastrophic failure.
