When developing an information system, organisations are faced with a fundamental choice: to buy a pre-developed package (potentially customise it or redesign/reengineer the business processes of the company concerned to fit the package), or to build the system in-house. Past literature has indicated the importance of the buy vs build decision to the organisation even suggesting that correctly ...

The aims of this study were to examine the ultimate strength of the restored maxillary incisors with composite resin, dental amalgam and glassionomer cement as a transitional restoration. Fifty-six extracted human maxillary central incisors with intact and carious dentin were used. The control group consisted of eight unrestored teeth with intact dentin. Artificial defect in dentin was up to th...

Teeth that have been endodontically treated often have little coronal tooth tissue remaining and, as such, require a post to retain the core and restoration, and need to be restored by crowns1,5,9. Metal posts are most commonly used due to their favourable physical properties and excellent biocompatibility4,8. With recent advances in ceramic technology, the all-ceramic crown has become more pop...

AIM To investigate the load capability of root filled teeth restored with glass fibre posts when the same self-adhesive composite resin cement was used as post cement and core build-up material. METHODOLOGY Human maxillary central incisors were divided into four groups (n=10). Teeth were root filled, decoronated and restored using glass fibre posts luted with different cements and composite r...

OBJECTIVE Depth of cure of composite material is restricted and it depends on many parameters such as thickness. The aim of this in-vitro study was to evaluate the depth of cure of two light-cured core build-up composites (Quixfil and Photocore) in different thicknesses, when cured for 60 seconds. MATERIALS AND METHODS The Vickers microhardness measurements were made for each side of the top ...

OBJECTIVE This study aimed to evaluate and compare the mechanical properties of five commercial core materials using fracture toughness (FT), Knoop hardness number (KHN), diametral tensile strength (DTS), and dynamic elastic moduli (DEM). METHODS Composite material specimens were produced (Rock Core, CosmeCore, ParaCore, MultiCore Flow, and Filtek Supreme Plus). The FT test (n = 15) was perfo...

Takeuchi Mfg.'s core products are compact excavators, track loaders, and other compact construction equipment used to build homes and other buildings. Internet of Things (IoT) utilization has recently become a major topic in the manufacturing industry, and Takeuchi Mfg. has set its sights on leveraging IoT as it continues to push reforms, implement a wide variety of IT systems, and build new fa...
