AIM To achieve retention in severely resorbed mandibular ridges during impression making and to maintain the retention and stability of these dentures during function. BACKGROUND No good method with adequate clinical photographs that will empower the dentist with the necessary skill has been reported in the literature. TECHNIQUE The technique involves making a preliminary impression in algi...

Injection-moulding is one of the most common manufacturing processes used for polymers. In many applications, the mechanical properties of the product is of great importance. Injection-moulding of thin-walled polymer products tends to leave the polymer structure in a state where the mechanical properties are anisotropic, due to alignment of polymer chains along the melt flow direction. The anis...

During the last decade, the development in metallic material additive manufacturing (formerly also known as Rapid Manufacturing, RM or Rapid Tooling, RT) has brought this technology from niche applications and short run tooling to be a competitive method capable of producing complex geometries in industrial grade materials, such as for example injection moulding tool inserts with integrated con...

Polyetheretherketone (PEEK) is a high-performance thermoplastic biomaterial which is currently used in a variety of biomedical orthopaedic applications. It has comparable tensile and compressive strength to cortical bone with favourable biocompatibility. However, natural grade PEEK-OPTIMA has shown insufficient bioactivity and limited bone integration. Bioactive PEEK composites (e.g., PEEK/calc...

Microbial mats have been hypothesized to improve the persistence and the preservation of organic remains during fossilization processes. We test this hypothesis with long-term experiments (up to 5.5 years) using invertebrate and vertebrate corpses. Once placed on mats, the microbial community coats the corpses and forms a three-dimensional sarcophagus composed of microbial cells and exopolymeri...

This research presents a case study of production monitoring on an aerospace composite component: the hinge arm of the droop nose mechanism on the Airbus A380 wing leading edge. A sensor network composed of Fibre Bragg Gratings, capacitive sensors for cure monitoring and thermocouples was embedded in its fibre reinforced lay-up and measurements were acquired throughout its Resin Transfer Mouldi...
