1. A dental system comprising:
an implant abutment having threads;
a definitive screw having an axis with a length measured along the axis and a width measured perpendicular to the axis, the definitive screw having a proximal head end having a tool interface and a distal post portion having threads configured to engage the threads of the implant abutment;
a coping having a proximal end with an aperture, wherein the aperture is larger than the distal post portion of the definitive screw and smaller than the proximal head end of the definitive screw; and
a temporary screw having an axis with a length measured along the axis and a width measured perpendicular to the axis, the temporary screw comprising:
a proximal head portion with a width larger than the aperture of the coping; and
a distal shaft portion with threads in a pattern that is shaped differently from a pattern of the threads of the definitive screw,
wherein the temporary screw is rotatable in a distal direction whereby the distal shaft portion of the temporary screw engages the threads of the implant abutment to a predetermined torque which causes the proximal head portion of the temporary screw to hold the coping in alignment with the implant abutment, and wherein an axial force in a proximal direction from pick-up processing releases the coping and the temporary screw from the implant abutment.
