Fracture-resistant monolithic dental crowns [PDF]
Dental Materials, 2016 To quantify the splitting resistance of monolithic zirconia, lithium disilicate and nanoparticle-composite dental crowns.Fracture experiments were conducted on anatomically-correct monolithic crown structures cemented to standard dental composite dies, by axial loading of a hard sphere placed between the cusps.

Fracture Resistance of Reattached Hydrated Fragment of Fractured Incisors
International Journal of Clinical Pediatric Dentistry, 2020 Fragment reattachment procedure provides conservative treatment option when an intact fractured fragment is available. Rewetting of fractured fragment before reattaching has shown better bond strength of attached fragment. Therefore, fracture resistance of reattached fractured fragment with hydration and without hydration was evaluated and compared ...

Toughening materials: enhancing resistance to fracture [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2021 It has been said that ‘God invented plasticity, but the Devil invented fracture!’ Both mechanisms represent the two prime modes of structural failure, respectively, plastic collapse and the rupture/breaking of a component, but the concept of developing materials with enhanced resistance to fracture can be difficult.
