Abstract
Abstract A means for fastening a capping on bone tissue or the like over an area of original, locally depressed, chipped or fractured tissue to promote the growth of additional tissue is disclosed, comprising generally, a pin which has, at one end, a bead for attachment of a foil and, at the other end, an external thread for threading into the original tissue or bone. Between the bead and the thread is a smooth-walled segment whose diameter is preferably larger than the diameter of the external thread. The method, unlike previous prior art methods, facilitates growing of the bone between two teeth or between teeth and a denture. The method permits, for example, restoring a jawbone to a larger extent than over areas where there were only slight depressions.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
133 words
A method of securing a cover over an area of original, locally depressed, chipped, or fractured tissue to promote the growth of additional tissue, comprising the steps of: providing a pin having, on one end, external thread and, on another end, internal thread and a bead, wherein said bead has an engagement face for engaging a rotational tool; providing a cylindrical, smooth-walled segment between said bead and the external thread, wherein the diameter of said segment is greater than or equal to the diameter of the external thread; detachably securing said external thread into or near the original tissue; covering said pin and said area with a foil; and threading a cap screw into said internal thread of the pin, wherein said cap screw retains said foil against said bead of the pin.
Claim 2
Independent Claim
133 words
A method of securing a cover over an area of original, locally depressed, chipped, or fractured tissue to promote the growth of additional tissue, comprising the steps of: providing a pin having, on one end, external thread and, on another end, internal thread and a bead, wherein said bead has an engagement face for engaging a rotational tool; providing a cylindrical, smooth-walled segment between said bead and the external thread, wherein the diameter of said segment is greater than or equal to the diameter of the external thread; detachably securing said external thread into or near the original tissue; covering said pin and said area with a foil; and threading a cap screw into said internal thread of the pin, wherein said cap screw retains said foil against said bead of the pin.
