Abstract (EN): The use of adhesives as an auxiliary way of prosthesis' retention has increased over the years. This can be explained by the functional implications that arise from poor retention/stability of total removable dentures and by the improvement of adhesive proprieties of this kind of materials. The main aims of this study were: to test the use of an intra-oral transducer in evaluation of the strength of desinsertion of total maxillary prosthesis; to evaluate the effect of adhesives on retention of these prostheses and to compare the results of different adhesives tested. The evaluation was done by quantifying the strength of the prosthesis desinsertion when subjected to vertical tensile tests, using, for this purpose, an intra-oral resistive transducer with 4 extensometers (120 Omega), forming a Wheatstone's bridge. All adhesives improved retention of complete upper dentures. The intra-oral transducer used has proved to be an appropriate instrument for the aims of this study.
