Abstract: An improved prosthetic dentistry method and an improved dental prosthetic device wherein the prosthetic device includes an implant disposable in a fresh extraction site or a surgically produced extraction site as the patient conditions dictate, and a crown removably attachable to the implant. The implant has a configuration shaped to encourage hard tissue and bone ingrowth into and through portions of the implant for increasing the mechanical interlock between the implant and the existing alveolar bone. In practice, the implant is inserted into the socket opening formed at the extraction site and, after a healing period sufficient to assure the required mechanical interlock, the crown is secured to the implant, thereby providing a free-standing dental prosthetic device which does not require the adjacent teeth for support purposes. The crown would preferably be attached immediately in those instances involving the replacement of anterior teeth.
