Abstract Objectives Mismatch in thermal expansion properties between veneering ceramic and metallic or high-strength ceramic cores can induce residual stresses and initiate cracks when combined with functional stresses. Knowledge of…
Abstract Aim To analyze the distribution of stresses at the bond interface of Molloplast-B soft-liner attached to PMMA acrylic surface of different geometries (smooth and rough) and at different load-application…
Abstract Objectives This study evaluated the risk of failure for an endodontically treated premolar with MOD preparation and three CEREC ceramic restoration configurations. Methods Simulations were performed based on three…
Abstract Objective In restored teeth, stresses at the tooth–restoration interface during masticatory processes may fracture the teeth or the restoration and cracks may grow and propagate. The aim was to…
Abstract Objectives To review the current status and understanding of Portland cement-like endodontic materials commonly referred to by the trade designation “MTA” (alias “Mineral Trioxide Aggregate”), and to present an…
Abstract Objective The aim of this paper is to validate the use of a finite-element (FE) based continuum damage mechanics (CDM) failure model to simulate the debonding and fracture of…
Abstract Objectives This study demonstrates the effects of nano-scale prepolymer particles as additives to model dental monomer and composite formulations. Methods Discrete nanogel particles were prepared by solution photopolymerization of…
Abstract Objective To investigate the contributions of BisGMA:TEGDMA and filler content on polymerization stress, along with the influence of variables associated with stress development, namely, degree of conversion, reaction rate,…
Abstract Objectives Piston-on-three-ball tests have been selected by the International Organization for Standardization to establish ISO 6872 for the evaluation of the biaxial strength of dentistry–ceramic materials. However, the formula…
