Abstract Objective Quaternary amine charge density is important because when the negatively charged bacteria contact the positive quaternary amine charge, the electric balance is disturbed and the bacterium could be…
Abstract Objective Evaluate the effect of implant connection designs on reliability and failure modes of screw-retained all-ceramic crowns. Methods Central incisor ceramic crowns in zirconia abutments were screwed and torqued…
Abstract Objective The applicability of the edge chipping method to denture tooth materials was assessed. These are softer materials than those usually tested by edge chipping. The edge chipping fracture…
Abstract Objective The major aim of this study was to prove the capability of the optical coherence tomography (OCT) method in visualizing the integrity of the adhesive fillings and of…
Abstract Objectives To analyse the marginal fit of 4-unit fixed dental prostheses (FDPs) and the accuracy of three-dimensional cast-datasets using both approaches to Computer Aided Design (CAD)/Computer Aided Manufacturing (CAM):…
Abstract Objectives To evaluate the effects of chlorhexidine (CHX) addition in different concentrations into simplified etch-and-rinse adhesives on the ultimate tensile strength (UTS), water sorption (WS), solubility (SO) and the…
Abstract Objective The aim of this study was to measure the linear elastic material properties of direct dental resin composites and correlate them with their fatigue strength under cyclic loading….
Abstract Objective The edge chipping test was used to measure the fracture resistance of CAD/CAM dental restoration ceramics and resin composites. Methods An edge chipping machine was used to evaluate…
Abstract The edge chipping resistances of six CAD/CAM dental restoration materials are analyzed and correlated to other mechanical properties. A new quadratic relationship that is based on a phenomenological model…
Abstract Objectives To test the null hypotheses that photoactive resin composites containing a Type I photoinitiator would exhibit reduced DC or increased monomer elution at substantially short curing times compared…
Abstract Objectives To examine effects of shrinkage and modulus on the dynamic development of shrinkage stress as a function of methacrylate conversion and filler loading in a model photocurable dimethacrylate-based…
Abstract Objectives To evaluate the effect of infrastructure (IS) material on the fracture behavior of prosthetic crowns. Methods Restorations were fabricated using a metal die simulating a prepared tooth. Four…

Abstract Objectives To assess transient and residual stresses within the porcelain of veneered restorations (zirconia and metal) as a result of cooling rate and porcelain thickness. Methods Porcelain-on-zirconia (PZ) and…
Abstract Objectives To characterize the microstructure and determine some mechanical properties of a polymer-infiltrated ceramic-network (PICN) material (Vita Enamic, Vita Zahnfabrik) available for CAD–CAM systems. Methods Specimens were fabricated to…
Abstract Objective To study the effect of compositional variables and temperature (25 °C and 37 °C) on the rheological properties of contemporary resin composites. Methods Fourteen commercial resin composites with…
Abstract Objectives Calcium phosphate cement (CPC) is promising for dental and craniofacial repairs. Vascularization in bone tissue engineering constructs is currently a major challenge. The objectives of this study were…
Abstract Objective Selective laser melting (SLM) is increasingly used for the fabrication of customized dental components made of metal alloys such as CoCrMo. The main aim of the present study…
Abstract Objectives The degree and rate of photopolymerization in resin-based dental composites will significantly affect polymer network formation and resultant material properties that may determine their clinical success. This study…
Abstract Objective The purpose of this study was to compare the use of different variables to measure the clinical wear of two denture tooth materials in two analysis centers. Methods…
