1. A device for implanting an artificial endosseous element containing:
- an implant screw pin, said pin being of a radio opaque ceramic and having an external threading, said pin including a portion to be threaded into a bone structure and a protruded portion to be protruded from the upper surface of said bone structure when said pin is threaded into the bone structure, said pin being provided with a tool-attaching portion at the top of said protrusion, anda nut element made of ceramic, said nut element being substantially larger in diameter than said pin, said nut element being threaded onto said protruded portion of said pin until the underside of said nut element engages with the upper surface of said bone structure thereby tightly holding said pin in said bone structure.

Abstract
This invention is directed to a device for implanting an artificial endosseous element of ceramics in the fields of dentistry, oral surgery and orthopedics, comprising an implant screw pin and more than one nut element in combination with said screw pin primarily for securely holding said screw pin in a bone structure after implantation thereof. This invention is also directed to an implant method for use of such device.

9. A method of implanting an artificial endosseous element into a bone structure of a human body for restoring said bone structure to its original configuration containing the steps of:
-
forming a tapped hole in said bone structure; screwing into said tapped hole an externally threaded implant screw pin of ceramics until the upper portion of said pin is below the top surface of the gingival tissue and protrudes from said bone structure and until the bottom of said pin is in hard tissue at the lower side of said bone structure; and screwing a nut element of ceramics onto said protruded portion of said pin until the underside of said nut element engages with the upper surface of said bone structure to tightly hold said pin in said bone structure. - View Dependent Claims (10)

11. A method of implanting artificial dental endosseous element into a bone structure of a human jaw for restoring said bone structure to its original configuration containing the steps of:
-
forming a tapped hole in said bone structure; screwing into said tapped hole an externally threaded implant screw pin of ceramics until the upper portion of said pin is below the top surface of the gingival tissue and protrudes from said bone structure and until the bottom of said pin is in hard tissue at the lower side of said bone structure; screwing a nut element of ceramics onto said protruded portion of said pin until the underside of said nut element engages with the upper surface of said bone structure to tightly hold said pin in said bone structure; and securely fixing an artificial tooth to said nut element through an adhesive compound.

12. A device for implanting an artificial endosseous element containing:
-
an implant screw pin, said pin being of ceramics and having an external threading, said pin including a portion to be threaded in a bone structure in an upper and lower protruded portion to protrude from the upper and lower surfaces of said bone structure when said pin is screwed into said bone structure, said pin being provided with a tool attaching portion at the bottom thereof, a first nut element, said first nut element being screwed onto the lower protruded portion of said screw, a second nut element, said second nut element being substantially larger in diameter than said pin, said second nut element being screwed onto the upper protruded portion until the underside of said nut element engages with the upper surface of said bone structure thereby holding said pin in said bone structure. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A method of implanting an artificial endosseous element into a bone structure of a human body for restoring said bone structure to its original configuration containing the steps of
forming a single tapped hole penetrating throughout said bone structure; -
screwing into said tapped hole an externally threaded implant screw pin of ceramics so as to permit an upper and lower portion of said screw of the pin to be upwardly and downwardly protruded from said bone structure; screwing a first nut element of ceramics onto said lower protruded portion; and screwing a second nut element of ceramics onto said upper protruded portion of said pin until said lower surface of said second nut element engages with the upper surface of said bone structure thereby tightly holding said pin in said bone structure. - View Dependent Claims (21)

22. A method of implanting an artificial dental endosseous element into a bone structure of a human jaw for restoring said bone structure to its original configuration comprising:
-
forming a tapped hole penetrating through said bone structure; screwing into said tapped hole an externally threaded implant screw pin of ceramics so as to permit an upper and lower portion of said threading of said pin respectively to be upwardly and downwardly protruded from said bone structure; screwing a first nut element of ceramics onto said lower protruded portion;
screwing a second nut element of ceramics onto said upper protruded portion of said pin until the lower surface of said second nut element engages with the upper surface of said bone structure thereby tightly holding said pin in said bone structure; andsecurely fixing an artificial tooth to said upper nut element through an adhesive compound.
