The dental prosthetic device of claim 1 wherein the means connecting the end portions of the rods includes a portion forming an upwardly facing surface disposed within the open space between the plate lower face and the connected end portions of the rods, the hard and soft tissue ingrowth within the open space engaging the upwardly facing surface formed on a portion of the means connecting the end portions of the rods resisting the removal of the plate and the rods from the socket opening formed at the extraction site. 3. The dental prosthetic device of claim 1 wherein the base is defined further as being disposed in a portion of the open space defined via the rods and having a recess formed in a portion thereof intersecting the upper end and forming an upwardly facing surface extending circumferentially about the base between the upper and the lower ends thereof, the upwardly facing surface on the base being spaced a distance below the lower face of the plate, the hard and soft tissue ingrowth within the open space and about the recess portion of the base engaging the upwardly facing surface formed on the base for resisting removal of the plate and the rods connected thereto from the socket opening formed at the extraction site. 4. The dental prosthetic device of claim 3 wherein the base is defined further to include portions connected to a portion of each rod, generally between the ends of the rod connected to the plate and the means connecting the ends of the rods, thereby enhancing the structural integrity of the rods extending from the plate. 5. The dental prosthetic device of claim 1 wherein the rods are connected to the lower face of the plate and extend a distance therefrom toward the means connecting the end portions of the rods generally along a slightly curved path providing an overall conical shape to the plate and the rods connected thereto, the rods being spaced circumferentially about the plate and each rod being spaced from adjacent rods, the spacing between the rods providing communication with the open space defined via the rods. 6. A prosthetic dentistry method for installing a dental prosthetic device including an implant and a crown, comprising the steps of: preparing the socket opening at a predetermined extraction site for receiving the implant; inserting the implant into the socket opening; removable securing a threaded fastener to the implant, a portion of the fastener extending above the implant; inserting a cap over the portion of fastener extending above the implant; disposing a temporary crown on the implant, a portion of the temporary crown being disposed over the cap; securing the temporary crown in a relatively stationary position to hold the implant in a substantially stationary position during a predetermined healing period allowing hard and soft tissue ingrowth about the implant; removing the temporary crown after the healing period; making an impression over and about the implant to obtain the spacial disposition between the implant and adjacent teeth; making a crown utilizing the impression to determine the required spacial disposition of the crown; and securing the crown to implant. 7. A prosthetic dentistry method for installing a dental prosthetic device including an implant and a crown, comprising the steps of: preparing the socket opening at a predetermined extraction site for receiving the implant; inserting the implant into the socket opening; disposing a temporary crown on the implant and connecting the temporary crown to the implant; securing the temporary crown to the adjacent teeth for holding the temporary crown in a relatively stationary position with respect to the adjacent teeth, thereby securing the implant in a relatively stationary position with respect to the adjacent teeth during a predetermined healing period allowing hard and soft tissue ingrowth about the implant; and securing the crown to the implant via a removable fastener extending through a portion of the crown and a portion of the implant removably securing the crown to the implant. 8. A dental prosthetic device having a portion insertable within a socket opening formed at an oral extraction site, comprising: a plate having an upper face, a lower face and protrusions formed on the upper face thereof and extending a distance thereform; at least two rods, one end of each rod connected to the plate and each rod extending a distance from the lower face of the plate; means connecting the end portions of the rods, opposite the ends of the rods connected to the plates, the rods defining an open space between the plate and the means connecting the end portions of the rods, the rods and the means connecting the end portions of the rods being insertable within the socket opening formed at the extraction site and shaped to facilitate hard and soft tissue ingrowth within a portion of the open space and about the rods for forming a mechanical interlock; a crown, having an upper end and a lower end, disposable on the upper face of the plate in one position of the dental prosthetic device, depressions formed in the lower end of the crown and each of the protrusions on the plate being in one of the depressions in the crown and engaging adjacent portions of the crown for substantially preventing rotational movement of the crown on the plate in the one position of the crown secured to the plate; and 9. A dental prosthetic device having a portion insertable within a socket opening formed at an oral extraction site and utilizing a temporary crown or the like comprising; a plate having an upper face, a lower face and a single opening extending through a portion thereof; means connected to the plate and extending a distance from the lower face of the plate and defining an open space between the plate and said means connected to the plate, said means being insertable within the socket opening formed site and shaped to facilitate hard and soft tissue ingrowth during a healing period within a portion of the open space and about said means for forming a mechanical interlock; a base, having an upper end, a lower end, and a threaded opening intersecting the upper end and extending a distance through a portion of the base, the upper end of the base connected to the lower face of the plate and the threaded opening in the base being alignable with the opening in the plate, the connection between the base and the plate sealing the threaded opening in the base from the open space defined via the rods whereby the temporary crown is removably securable to the plate for holding the base, the plate and the means connected to the plate in a relatively stationary position during the healing period; and a crown, having an upper end and a lower end, the lower end of the crown being disposable on the upper face of the plate in one position of the dental prosthetic device and an opening extending through a portion of the crown intersecting the lower end thereof, the opening in the crown being alignable with the opening in the plate in the position of the dental prosthetic device of the crown connected to the plate; and a fastener having a portion insertable through the opening in the crown and through the opening in the implant, a portion of the fastener threadedly engaging the threaded opening in the implant and a portion of the fastener engaging a portion of the crown, the fastener removably securing the crown to the plate. 10.
