This clinical report describes the prosthodontic treatment for an 18-year-old man diagnosed with amelogenesis imperfecta. The aim of treatment was to reduce dental sensitivity and to restore esthetics and masticatory function. Metal-ceramic fixed partial dentures were placed on posterior teeth to modify the occlusion, and porcelain laminate veneers were placed to improve the esthetics of the ma...

Abstract The use of composite materials in structural applications has significantly expanded recent years. transport industry accounts for an increasingly larger share the final weight vehicles, as manufacturers pursue improvements fuel economy, lighter more efficient designs, and reduction emissions. However, delamination adhesively bonded joints causes premature failure bond, inhibiting its ...

In this paper, a new shape memory alloy (SMA) hybrid basalt fibre reinforced polymer (BFRP) composite laminate was fabricated and a new surface modification method with both silane coupling agent KH550 and Al₂O₃ nanoparticles was conducted to enhance the interface performance. The mechanical performance of BFRP composite laminates with and without SMA fibres and the influence of SMA surface mod...

Fully integrated monitoring systems have shown promise in improving confidence in composite materials while reducing lifecycle costs. A distributed optical fibre sensor is embedded in a fibre reinforced composite laminate, to give three sensing regions at different levels through-the-thickness of the plate. This study follows the resin infusion process during fabrication of the composite, monit...

Abstract Shape morphing is an attractive functionality for fibre reinforced composites. composites can adopt various shapes and undergo different shape morphologies in response to a set of external stimuli. One the approaches attain materials through fabrication multi-layered asymmetric where stems from structural anisotropy. In this work, hybrid carbon fibre/glass fibre/epoxy are manufactured ...

AIM To compare the fracture resistance of thin-walled roots after restoration with different types of post systems. METHODOLOGY One hundred and sixty-five decoronated maxillary central incisors were root filled and randomly assigned to three groups with respect to the remaining dentine thickness of root (1.0 mm, 1.5 mm, 2.0 mm). Each group was randomly divided into five equal subgroups. The s...

A micro-mechanical model for fibre bundle failure is formulated following a phase-field approach and embedded in semi-analytical homogenisation scheme. In particular mesh-independence consistency of energy release rate bundles matrix phase are ensured dominated failure. Besides, the cracking fibre-matrix interface debonding modelled through evolution damage variable framed an implicit non-local...
