Comparison of Mandibular Arch Expansion by the Schwartz Appliance Using Two Activation Protocols: A Preliminary Retrospective Clinical Study by Vincenzo Quinzi, Stefano Mummolo, Francesca Bertolazzi, Vincenzo Campanella, Giuseppe Marzo, Enrico Marchetti

“…Materials and Methods: We compared two groups of patients treated with different activation’s protocols of the lower Schwartz appliance (Group 1 protocol consisted in turning the expansion screw half a turn twice every two weeks and replacing the device every four months; Group 2 was treated by using the classic activation protocol—1/4 turn every week, never replacing the device). …”

Effect of the saliva biomolecules on the interface zirconia/Ti6Al4V triboactivity by H. Teixeira, A.P Serro, C. G. Figueiredo-Pina

“…AbstractIntroduction In some dental implants zirconia artificial dental crowns are fixed through a custom-built abutment made of a titanium alloy (Ti6Al4V) that, in turn, is tightly screwed to the implant. The rotational misfit at the implant-abutment hexagonal interface can lead to relative motion between the parts, resulting in interfacial wear. …”
