Abstract: An osteointegrated implant comprises a shank formed with external threads at one end receivable in a bone formed in the jawbone; a cap at the opposite end of the shank and formed with an apertured end wall, to which cap a crown, bridge or denture is securable; a threaded pin threadable into the opposite end of the shank through the apertured end wall of the cap and having an enlarged head for removably securing the cap to the shank; and a shock-absorber spring interposed between the cap and the opposite end of the shank to absorb mastication forces applied to the crown, bridge or denture when secured to the cap.
