  • Patent number: 5820374
    Abstract: An integral dental implant includes an upper end having an upper surface including an abutment attachment recess extending axially inwardly from the upper surface. The implant also includes an apical end including a lower surface opposite to the upper surface. The implant further includes a substantially cylindrical surface extending between the upper and lower surfaces, the cylindrical surface including a large number of linear grooves which define a substantially diamond-like pattern upon the cylindrical surface. The diamond-like pattern is defined by a combination of substantially circumferential grooves, substantially longitudinal groove, and substantially diagonal grooves.

  • Patent number: 5622499
    Abstract: 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.
