Modifications in implant placement at the initial surgery can pose significant rehabilitation problems at second-stage surgery, and the selection of an inappropriate abutment at this time can further complicate the situation. In spite of the significant evolution of a number of implant systems, implant design and features, those related to the mechanical behavior of implant-supported prostheses should be given utmost importance. From an engineering point of view, the internal hexed implant with a Morse taper is definitely a better connection than an external hex implant that absolutely depends on the screw to hold the abutment in place. Morse taper connection has shown promising results in terms of stronger connection, better load transfer and reduced micro-movement.
