Effect of Bleaching Agent on Interfacial Fracture Toughness of Resin Composite-dentin Interfaces
The effect of bleaching on fracture toughness (Kic) of existing composite-dentin interfaces was assessed using the notchless triangular prism (NTP) specimen fracture toughness test. Human molars and premolars (<6 months old) were wet ground on 600 SiC to obtain 4x4x4x4mm triangular prisms with buccal or lingual exposed for bonding. Buccal or lingual dentin surfaces, ground on 600 grit sandpaper...
متن کاملTensile bond strength of indirect composites luted with three new self-adhesive resin cements to dentin
OBJECTIVE The aims of this study were to evaluate the tensile bond strengths between indirect composites and dentin of 3 recently developed self-adhesive resin cements and to determine mode of failure by SEM. MATERIAL AND METHODS Exposed dentin surfaces of 70 mandibular third molars were used. Teeth were randomly divided into 7 groups: Group 1 (control group): direct composite resin restorati...
متن کاملSTRENGTH AND FRACTURE TOUGHNESS OF WHISKER REINFORCED DENTAL RESIN-BASED COMPOSITES
Enhancing the properties of dental resin composites is of interest to researchers. The objective of the present investigation was to improve the strength and fracture toughness of dental composites via addition of silicon carbide whiskers and substitution of commonly used filler materials with stabilized zirconia ceramic powder. It was also intended to study the effect of powder- to- whisker ra...
متن کاملReconstruction of frontal bone using specific implant polyether-ether-ketone.
Defects on the craniofacial complex may result in aesthetic defects, functional damage, and psychologic consequences. Previously, surgeons showed no interest in reconstructing the operated area, but in the treatment of the problem, leaving bone contour is a secondary issue. Nowadays, area reconstruction with post-reestablishment of contour and local shape has become one of the surgeon's priorit...
متن کاملLocal deformation behavior of surface porous polyether-ether-ketone.
Surface porous polyether-ether-ketone has the ability to maintain the tensile monotonic and cyclic strength necessary for many load bearing orthopedic applications while providing a surface that facilitates bone ingrowth; however, the relevant deformation behavior of the pore architecture in response to various loading conditions is not yet fully characterized or understood. The focus of this s...
