[Cyanoacrylates as a cementation material in fixed prosthodontics]

The purpose of this study was to examine and compare, in the same experimental conditions, the effects and the behaviour of two different materials, using them for cementation of a prosthetic reconstruction: a cianoacrilic compound (B20 cianoacrilate 3M); a traditional cement of zinc phosphate (Harvard Cement). The comparative study with the optical microscope between butilcianoacrilate and traditional cement has shown minimum levels of marginal discrepancy for both materials examinated (about 13 microns). The high resistance of cianoacrilate to traction, compared with the other fixing cement, makes us conclude this study in the hope that further research could confirm and introduce this materials in the practice of prosthetic dentistry.
