Screw, head-lock, to abutment of dental implant body

A locking system for screws comprising:

• a) an abutment, said abutment being positioned over a bore hole, said abutment having an upper portion, said upper portion of said abutment having at least one groove formed therein, and a space for receiving a screw head;
• b) a screw being threaded into said bore hole, said screw having a head, the head of said screw being fitted into the space for receiving a screw head in said abutment, said screw head also having at least one groove formed therein, such that when said screw is tightened onto said abutment, said at least one groove formed in said screw head is operatively aligned with said at least one groove formed in said abutment;
• and
• c) a quantity of fill material, placed in said abutment such that the at least one groove in said abutment and the at least one groove in said screw head are filled with said quantity of fill material to create a solid bond between said screw head and said abutment.

A locking system for screws used in securing an abutment to a dental implant comprising:

• a) an abutment, said abutment being positioned over an implant body having a bore hole formed therein, said abutment having an upper portion, said upper portion of said abutment having a plurality of spaced-apart grooves formed therein, and a space for receiving a screw head;
• b) a screw being threaded into said bore hole, said screw having a head, the head of said screw being fitted into the space for receiving a screw head in said abutment, said screw head also having a plurality of spaced-apart grooves formed therein, such that when said screw is tightened into said abutment, at least two of said plurality of spaced-apart grooves formed in said screw head are operatively aligned with at least two of said plurality of spaced-apart grooves formed in said abutment;
• and
• c) a quantity of fill material, placed in said abutment such that the plurality of spaced-apart grooves in said abutment and the plurality of spaced-apart grooves in said screw head are filled with said quantity of adhesive material to create a solid bond between said screw head and said abutment.

A dental implant inserted in a jaw bone having an abutment, a retaining screw and a crown, wherein the improvement comprises:

• a) said abutment having a plurality of spaced-apart grooves formed therein;
• b) said screw having a screw head having a plurality of spaced-apart grooves formed therein;
• c) such that when said screw is in a tightened position, at least two of said plurality of spaced-apart grooves formed in said abutment are in alignment with at least two of said plurality of spaced-apart grooves formed in said screw head;
• and
• d) a quantity of fill material, placed in said plurality of spaced-apart grooves formed in said abutment and said screw head such that when said quantity of fill material is hardened, said screw head and abutment are locked together.

A method of installing a dental implant comprising the steps of:

• a) drilling a hole in a patient's jawbone;
• b) securing an implant body into said patient's jawbone;
• c) placing an abutment, over said implant body, said abutment having an upper portion, said upper portion of said abutment having a plurality of spaced-apart grooves formed therein, and a space for receiving a screw head;
• d) threading a screw into said implant body, said screw having a head, the head of said screw being fitted into the space for receiving a screw head in said abutment, said screw head also having a plurality of spaced-apart grooves formed therein, such that when said screw is tightened into said abutment, at least two of said plurality of spaced-apart grooves formed in said screw head are operatively aligned with at least two of said plurality of spaced-apart grooves formed in said top of said abutment;
• e) placing a quantity of fill material in said abutment such that the plurality of spaced-apart grooves in said abutment and the plurality of spaced-apart grooves in said screw head are filled with said quantity of fill material;
• and
• f) curing said quantity of fill material to create a solid bond between said screw head and said abutment.
