Abstract
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. 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.

Method of manufacturing a dental abutment to assure a desired in situ alignment of the dental abutment with a dental implant, the method comprising the steps of: (a) providing a workpiece having therein a threaded recess corresponding to the length, diameter, pitch and material density of a coupling surface of the dental implant to be used in a dental procedure said recess having a mouth; (b) rotating into said recess a coupling surface of said dental abutment to be secured in situ to said dental implant said abutment having a non-threaded surface; (c) tightening said coupling surface of said dental abutment into said recess to a torque in the range of about 25 to about 35 newtons per centimeter; and (d) providing a surface of radial reference upon, and common to, both said non-threaded area of said abutment and a location, proximal to said mouth of said recess of said workpiece, whereby a desired degree of rotation and alignment of said abutment relative to said implant will be assured upon mutual alignment in situ of said surface radial of reference of said abutment and a dental implant provided with a reference corresponding to said radial reference of said workpiece.
Claim 3
Independent Claim
206 words
A method of manufacturing a dental abutment to assure desired in situ alignment of the dental abutment with the dental implant, the method comprising the steps of: (a) providing a workpiece having a material density of the dental implant to be used in a dental procedure and providing within said workpiece a threaded recess corresponding in length, diameter and pitch to that of a coupling surface of said dental implant; (b) providing upon said workpiece a radial reference relative to the longitudinal axis of said recess; (c) rotating into said recess a coupling surface of said dental abutment to be secured in situ to said dental implant; (d) tightening said coupling surface of said dental abutment into said recess to a torque in the range of about 25 to about 35 newtons per centimeter; and (e) providing a surface of radial reference upon a non-threaded area of said abutment which is radially aligned with said radial reference on said workpiece, whereby a desired degree of rotational alignment of said abutment relative to said implant will be assured upon mutual alignment in situ of said surface of reference of said abutment and a dental implant provided with a reference corresponding to said radial reference upon said workpiece.
Claim 4
Independent Claim
206 words
A method of manufacturing a dental abutment to assure desired in situ alignment of the dental abutment with the dental implant, the method comprising the steps of: (a) providing a workpiece having a material density of the dental implant to be used in a dental procedure and providing within said workpiece a threaded recess corresponding in length, diameter and pitch to that of a coupling surface of said dental implant; (b) providing upon said workpiece a radial reference relative to the longitudinal axis of said recess; (c) rotating into said recess a coupling surface of said dental abutment to be secured in situ to said dental implant; (d) tightening said coupling surface of said dental abutment into said recess to a torque in the range of about 25 to about 35 newtons per centimeter; and (e) providing a surface of radial reference upon a non-threaded area of said abutment which is radially aligned with said radial reference on said workpiece, whereby a desired degree of rotational alignment of said abutment relative to said implant will be assured upon mutual alignment in situ of said surface of reference of said abutment and a dental implant provided with a reference corresponding to said radial reference upon said workpiece.
Claim 5
Dependent Claim
