An investigation was carried out to examine the potential utilise densified wood dowels as a reinforcement for timber subjected compression loading perpendicular grain. While has high strength-to-weight ratio parallel grain, it demonstrates poor strength grain and in recent years there been significant number of studies examining use steel screws bonded-in rods this area. This is becoming more ...

Thin-walled roots restored using conventional cast metal post-cores are at risk of fracture. Placing a thick intermediate layer of resin-based composite (RBC), sandwiched between the root dentine and a small-diameter metal post or dowel, may improve the fracture resistance of such roots. In this initial laboratory study, two similar groups each of six decoronated maxillary central incisor teeth...

PURPOSE This study aimed to develop a copper-aluminium-nickel alloy which has properties comparable to that of dental alloys used for dental post and core applications with the reasonable cost. MATERIALS AND METHODS Sixteen groups of experimental copper alloys with variants of 3, 6, 9, 12 wt% Al and 0, 2, 4, 6 wt% Ni were prepared and casted. Their properties were tested and evaluated. The da...
