Claim 8:
9. A dental system for attachment of a coping to a threaded implant abutment comprising:
an implant abutment having female threading having an implant abutment thread profile;
a definitive screw having a longitudinal axis and a length measured along the axis and a width measured perpendicular to the axis, the definitive screw comprising:
a shaft with male threading, wherein the male threading has a male threading profile that matably threadably engages and which matches the female threading of the implant abutment; and
a head with a definitive screw drive interface;

a coping having a proximal end with an aperture sized to allow the definitive screw shaft to pass through; and
a temporary screw having a longitudinal axis and a length measured along the axis and a width measured perpendicular to the axis, the temporary screw comprising:
a post comprising male threading, wherein the male threading has a male threading profile that is different from the male threading profile of the shaft of the definitive screw, and wherein the aperture of the coping is sized and configured to allow the post to pass through; and
a head with a temporary screw drive interface, wherein the head is integral to or coupled to the post,

wherein the temporary screw holds the coping in position against the implant abutment for pick-up processing, wherein the male threading of the post of the temporary screw is configured to enter the implant abutment and rotatably engage the the female threading of the implant abutment to a predetermined pick-up processing torque, and wherein threads of the male threading of the post release from threads of the female threading of the implant abutment with a predetermined axial pick-up force in a proximal direction in response to and/or during pick-up processing.
