A method of manufacturing a dental abutment to assure a desired in situ alignment of the dental abutment with a dental implant includes the steps of, firstly, providing a workpiece having a threaded recess corresponding to the length, diameter, pitch and material density of a coupling surface of an implant to be used in a dental procedure, this step followed by the step of rotating into the recess a coupling surface of the dental abutment to be secured in situ to the dental implant. The third step of the inventive method includes the tightening of the coupling surface of the abutment into the recess to a torque in the range of about 25 to about 35 newtons per centimeter which step is followed by the step of providing a radial surface of reference upon, and common to, both a non-threaded area of the abutment and a location proximal to the mouth of the recess of the workpiece. Resultingly, a desired degree of rotation and alignment of the abutment relative to said implant will be assured upon mutual alignment in situ of the radial surface of reference of the abutment and a dental implant provided with a reference corresponding to the radial reference on the workpiece.
