RESUMO

The objective of this study was evaluate through extensometry the response of implant-suported frameworks in cobalt-chromium submitted to a load by the technique of monoblock, that simulate a case of mandibular protocol with 06 implants with a distance of 10 mm between each implant and a bilateral cantlever of 20 mm. In each abutment were pasted 04 strain gauges, making a bridge of Wheatstone, after squeezing all components of the piece of the monoblock, was submitted to a test with mechanical compressive loads with values of 150 N, quantitatively analyzing the data through extensometry, allowing accurate results. The results were obtained using the highest values recorded at each point of force applied, in the points L and R (cantilever bilaterally) for both axial load or 20, showed pure deflection, but when the load was applyed between p1 and p2, P3eP4, P4 eP5, P5eP6 respectively, was obtained a greater degree of compression (deflection) closer to the application of the load and more dstant to the applicarion of load, a little negative deflection was found by going to a positive deflection, suggesting movement of seesaw
