Universal dental implant abutment system

An implant abutment system for securing a prosthesis to a bone, comprising:

• an implant body implantable in a bone, said implant body including a reception end portion having coaxially disposed internal threads;
• an abutment collar including a proximal end portion adapted to receive the prosthesis and a distal end portion engageable with said implant body, said abutment collar having a axial, longitudinal bore extending therethrough;
• a fixation screw receivable in said longitudinal bore through a proximal opening in said abutment collar, said fixation screw including a threaded distal end portion engageable with said coaxially disposed internal threads of said implant body when received in said longitudinal bore, the bore of said fixation screw further including a section having internal threads therein for threaded engagement with a retention fastener of the prosthesis;
• and
• tapered means on said abutment collar proximal end and said implant body reception end providing frictional engagement between said abutment collar and said implant body.

An implant abutment system for securing a prosthesis to a bone, comprising:

• an implant body implantable in a bone said implant body including a reception end portion having coaxially disposed internal threads;
• an abutment collar including a proximal opening for receiving a fixation screw and a distal end portion engageable with said implant body, said abutment collar having a longitudinal bore extending from the proximal end to the distal end,
• a fixation screw receivable in said longitudinal bore through the proximal opening in said abutment collar, said fixation screw including an externally threaded distal end portion engageable with said coaxially disposed internal threads of said implant body when received in said longitudinal bore;
• and
• a means for frictional attachment of said abutment collar to said implant body wherein a portion of the implant body is inserted into an opening in the abutment collar and an extension portion of the abutment collar is inserted into an opening in the implant body.

An implant abutment system for securing a prosthesis to a bone, comprising:

• an implant body implantable in a bone said implant body including a reception end portion having coaxially disposed internal threads;
• an abutment collar including a proximal end portion for fixably receiving a prosthesis and a distal end portion engageable with said implant body, said abutment collar having a longitudinal bore extending therethrough;
• a fixation screw receivable in said longitudinal bore of said abutment collar, through a proximal opening thereof, said fixation screw including a threaded distal end portion engageable with said coaxially disposed internal threads of said implant body when received in said longitudinal bore;
• and
• means for frictional attachment of said abutment collar to said implant body wherein a portion of the implant body is inserted into a like-sized opening in the abutment collar and an extension portion of the abutment collar is inserted in to a like-sized opening in the implant body.

An implant abutment system for securing a dental prosthesis to a jawbone, comprising:

• an implant body implantable in the jawbone below a gumline, said implant body including a reception end portion having coaxially disposed internal threads;
• an abutment collar including a proximal end portion for fixably receiving the dental prosthesis and a distal end portion frictionally engageable with said implant body, said abutment collar having a longitudinal bore extending therethrough, the abutment collar adapted to reside within the gum line with at least a part of the proximal end portion extending above the gum line;
• a fixation screw receivable in said longitudinal bore through a proximal opening therein, said fixation screw including a threaded distal end portion engageable with said coaxially disposed internal threads of said implant body when received in said longitudinal bore;
• and
• means for preventing rotation between said abutment collar and said implant body.
