| 520 | 3 | |a STATEMENT OF PROBLEM The use of Morse taper connections is increasing, but little is known about the biomechanical use of abutments and their use in fixed prostheses. PURPOSE This study evaluated the transmission of load on the bone implant-supported dentures, varying the type of prosthetic connection and abutment. MATERIAL AND METHODS Using 4 polyurethane models, 3 implants were inserted into each block, establishing the following groups: (a) external hexagon and Micro-Unit abutments; (b) external hexagon and UCLA abutment; (c) Morse taper and Micro-Unit abutments; and (d) Morse taper and UCLA abutments. The prosthetic structures were cast, and in a universal testing machine, load was applied midway between the implants, with cantilever intervals of 5, 10, 15, 20, and 25 mm. Data were analyzed by Mann-Whitney, Friedman, and Kruskal-Wallis tests (P < 0.05). RESULTS Regarding the prosthetic connection, there was no difference in the use of hexagonal or Morse taper, but the use of Micro-Unit abutment showed lower deformation values than UCLA for the 2 connections. CONCLUSIONS The use of intermediate abutments affects the distribution of masticatory loads: the greater the length of the cantilever, the greater the surface deformation of the bone around the distal implant. | |
