[Comparative experimental studies on reconstructive miniplates].

Abstract

In an experimental study reconstructive miniplates consisting of 1.0 mm thick stainless steel and 1.27 mm thick pure titanium were comparatively examined. Plate stress trials showed better results for stainless steel in tension, and at the same time better results for titanium plates in bending trials over the edge and the plane. In lever trials of second order titanium plates showed equal or better results when used for reconstructing lower jaw specimens and plastic models. Our experimental results lead to the conclusion, that the plates tested can guarantee exercise stability of lower jaw reconstructions during the primary healing phase. Considering their more favorable E-modulus and better biocompatibility the new titanium miniplates with the dimensions mentioned are superior the stainless steel miniplates in the fixation of lower jaw grafts.
