The effect of coping/veneer thickness on the fracture toughness and residual stress of implant supported, cement retained zirconia and metal–ceramic crowns
Abstract Objectives The aim of the work was to assess the influence of coping and veneer thickness on the fracture resistance of porcelain–metal and porcelain–zirconia crowns in a clinically representative…
Cytocompatibility of polymer-based periodontal bone substitutes in gingival fibroblast and MC3T3 osteoblast cell cultures
Abstract Objectives Inflammatory periodontal diseases are accompanied by destruction of periodontal tissue and alveolar bone. Infrabony lesions can be regenerated with adequate bone substitutes, which require high biocompatibility of the…
Comparative mechanical behavior of dentin enamel and dentin ceramic junctions assessed by speckle interferometry (SI)
Abstract Objective The dentin–enamel junction (DEJ) plays a crucial role in dental biomechanics; however, little is known about its structure and mechanical behavior. Nevertheless, natural teeth are a necessary model…
Biomechanical evaluation of internal and external hexagon platform switched implant-abutment connections: An in vitro laboratory and three-dimensional finite element analysis
Abstract Objectives The aim of this study was to assess the effect of abutment’s diameter shifting on reliability and stress distribution within the implant-abutment connection for internal and external hexagon…
Development of strength in dental silver amalgam
Abstract Objectives To characterize the development of strength during the setting process of dental silver amalgam in the context of ‘early strength’ measurements for standards compliance testing in relation to…
Diametral compression test with composite disk for dentin bond strength measurement – Finite element analysis
Abstract Objective A novel technique using a composite disk under diametral compression was presented in a previous study for measuring the bond strength between intracanal posts and dentin. This study…
The interaction of various liquids with long-term denture soft lining materials
Abstract Objectives To study the uptake of liquids, representative of those encountered orally, by long-term denture soft lining materials, and analyze the data in terms of appropriate theories. Methods Four…
Sorption and solubility characteristics of self-adhesive resin cements
Abstract Objective The aim of this in vitro study was to evaluate some sorption characteristics [sorption ( S ), solubility ( SL ) and the percentages of mass change (M…
Interfacial nanoleakage and internal cement thickness of three esthetic crown systems
Abstract Objectives To evaluate interfacial nanoleakage expression of the combination of different cementation procedures and different crown systems. Methods Forty-five human premolars prepared to receive single crowns were randomly divided…
