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.
