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.
