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.
