Composites based on PLA with the addition of 3, 6 and 10 wt% silica, hydroxyapatite bentonite were obtained by twin-screw extrusion. Maleic anhydride grafted polyethylene was used to enhance interface interactions. The influence fillers Charpy impact strength, Rockwell hardness, tensile properties processing shrinkage investigated. Test samples 3D printing. highest strength hardness for composi...

The information contained in an interim implant-supported fixed acrylic resin complete denture is a starting point for fabricating the definitive restoration. Duplicating this information in an expedient, precise, and sanitary fashion is desirable so that the interim restoration can be returned to the waiting patient. A technique is described to fabricate an accurate definitive polyvinyl siloxa...

This research is conducted to improve the performance of plant fiber-based composites by inserting microcrystalline cellulose (MCC). MCC was incorporated into a mixture recycled high-density polyethylene (rHDPE) and cantala fiber at ratio 1, 2, 3, 4% wt. The rHDPE/cantala fiber/MCC were fabricated via twin screw extruder followed hot press. composite’s mechanical, physical, thermal properties t...

Polypropylene/Multiwall carbon nanotubes/Montmorillonite (PP/MWNTs/MMT) hybrid nanocomposites were prepared by using twin-screw extruder incorporating the polypropylene grafted maleic anhydride (PP-g-mA) as compotibilizer is used for better dispersion of nanoclay in the polymer matrix. The effect of MWNTs and MMT on the polypropylene matrix was investigated in terms of mechanical properties of ...

This case report describes the management of an oblique crown-root fracture of maxillary left lateral incisor. After removal of the fractured fragment, endodontic treatment, the remaining tooth was provisionally restored. The tooth was then orthodontically extruded by 3 mm to raise the defect supraginigivally. Periondonal fibres were cut with a surgical blade. A metallic screw type post was ins...

This paper presents the push-out experimental results of hybrid notch-screw (HNS) connections for timber-concrete composite structures. A total 7 groups specimens were designed and tested. The parameters included loading constraint conditions (i.e., test loaded either in local compression or uniform compression), shapes notches wood, screw number notch, notch width, inclusion a self-tapping rei...

No studies are available that evaluate the retention of disilicate crowns according to different cementation procedures. The purpose of this study was to measure the retention of lithium disilicate crowns cemented using two different cementation systems. Twenty extracted mandibular premolars were prepared. Anatomic crowns were waxed and hot pressed using lithium disilicate ceramic. Teeth were d...

BACKGROUND Screws placed in the distal fibula may not have satisfactory purchase during internal fixation of an osteoporotic ankle fracture. Tibia-pro-fibula screws that extend from the fibula into the distal tibial metaphysis provide additional purchase. The purpose of this study was to investigate if purchase of these screws can be enhanced further by injecting calcium sulfate and calcium pho...

Various applications of nanocomposites were a good motivation to start a study on this wide spreading field of science. Current research is an investigation on incorporating different percentages of TiO2 nanoparticle as reinforcement to a base material which here is poly methyl methacrylate (PMMA). In this study various percentages of TiO2 (0.5, 1 and 2 wt%) were added to pure PMMA and effect o...
