Removable dental prostheses are commonly fabricated using polymethylmethacrylate, a material that does not have favorable mechanical properties and needs reinforcement with particles such as graphene. The aim of this study was to evaluate the flexural strength (FS) Vickers microhardness heat-polymerized polymethylmethacrylate coated graphene-doped stannic oxide (SnO2) thin films thermionic vacu...

We study the average velocity of crack fronts during stable interfacial fracture experiments in a heterogeneous quasibrittle material under constant loading rates and during long relaxation tests. The transparency of the material (polymethylmethacrylate) allows continuous tracking of the front position and relation of its evolution to the energy release rate. Despite significant velocity fluctu...

Third generation cementing technique is now commonly used for total hip arthroplasty. The aim of this technique is to sufficiently pressurise the cement and allow maximal penetration of the cement into any remaining trabecular bone to provide a stable fixation of the prosthesis. We report a case where this pressurisation resulted in polymethylmethacrylate retrograde filling of the nutrient vess...

We studied the antiadhesive effect of Poloxamer 407 (P407), together with modifications in the antimicrobial susceptibility of residual adherent staphylococci. Bacterial adherence was markedly inhibited (77% to more than 99.9%) whether polymethylmethacrylate was exposed to P407 before or during the adherence assay. Furthermore, residual adherent staphylococci appeared to be more susceptible to ...

Introduction We have reported the efficacy of continuous hemodiafiltration (CHDF) with a cytokine-adsorbing hemofilter in the treatment of hypercytokinemia, such as severe sepsis, septic shock, using a polymethylmethacrylate (PMMA) membrane dialyzer (BK-2.1P; Toray Medical Co Ltd, Tokyo, Japan) [], []. In 2013, a new PMMA hemofilter (CH-1.8W; Toray Medical Co Ltd, Tokyo, Japan) was released in ...

Many investigators consider the polymethylmethacrylate-bone interface the weakest link in the bone-cement-implant system. Push-out tests, frequently used for in vitro evaluation of the bone-cement interface, produced inconsistent results of shear strength. Therefore, a more reliable model for testing the shear failure of the interface was developed. Better understanding of intrinsic variations ...
