Performance of Composite and Monolithic Prefabricated Vertical Drains
With the increasing use ofprefabricated vertical drains in the improvement of soft clay there are many types of these drains, both composite (with geotextile wrapping) and monolithic (without geotextile wrapping), available in Malaysia. Some engineers have the impression that all drains perform satisfactorily. However, case studies have shown that there are cases where vertical drains failed to...
متن کاملCast anterior bridges utilizing composite resin.
J. he loss of a permanent anterior tooth on a young patient poses unique problems in replacement for the pedodontic practitioner. Full crown coverage of the abutment teeth necessary for conventional fixed bridgework is often contraindicated due to the large size of the pulp chamber and the potential for pulpal damage. Even if possible, this reduction violates the current concepts of good conser...
متن کاملEtched casting acid etch composite bonded posterior bridges.
The development of composite bonded cast posterior bridges is followed through its evolution from the perforated to the electrolytically etched casting for resin retention. The current state of the art in design and preparation for these retainers is reviewed stressing the path of insertion, proximal extensions, occlusal rests and gingival extent. Retainer fabrication and the alloy specific nat...
متن کاملOriented nanomaterial air bridges formed from suspended polymer-composite nanofibers.
In a two-step method, carbon nanotubes, inorganic nanowires, or graphene sheets are connected between two anchor points to form nanomaterial air bridges. First, a recently developed method of forming directionally oriented polymer nanofibers by hand-application is used to form suspended composite polymer-nanomaterial fibers. Then, the polymer is sacrificed by thermally induced depolymerization ...
متن کاملBiomechanical Behaviour of Fiber Reinforced Composite Dental Bridges
The major interest of practitioners for FRC dental restorations derives from the biological traits of this technique. The study concerned the biomechanical behaviour of polyethylene fiber reinforced composites. The experimental determination of the maximum pressure force that can be supported by a FRC fixed prosthetic restoration has also been targeted (Construct Premise Indirect). For this pur...
