Customized single piece dental implant
A partially customizable single-piece dental implant includes a preformed bone-anchorage component and an abutment component that is custom milled from a block either preoperatively, (i.e., Process A) or intraoperatively, (i.e., Process B). In Process A, the planned abutment shape is designed by a computer-aided design (CAD) software based on a computerized tomographic scan and other patient data. Alternatively, under Process B, the position of the planned implant with respect to the alveolus is digitally captured (e.g., by an optical impression device or an intraoperative computerized tomographic scan). In both Process A and Process B, a blank implant having the millable block is held to allow a computer-aided manufacturing (CAM) machine to customize the abutment component, as well as part of the bone-anchorage component. The resultant dental implant is then inserted in the alveolus and either a provisional or permanent prosthesis can then be immediately loaded on the implant.
1. A customizable single-piece dental implant comprising:
a one-piece implant blank comprising:
a bone-anchorage component having external threads and an external surface texture;
a millable block on a top end of the bone-anchorage component, and the millable block and bone-anchorage component defining a unitary, one-piece body, and the millable block being structured and disposed to be milled by a computer-aided manufacturing machine to form a custom milled abutment component that is integral with the bone-anchorage component, and the millable block is configured to be milled by the computer-aided manufacturing machine (CAM) to provide a shoulderless margin slippage area at a base of the custom milled abutment component to allow for gingival recession; and
a CAM insert member extending from a top end of the millable block, and the CAM insert member is configured to be held by the computer-aided manufacturing machine during milling of the millable block to form the custom milled abutment component, wherein the millable block includes a plurality of threaded channels extending at least partially therethrough and at various angles relative to one another.
2. The customizable single-piece dental implant as recited in claim 1 further comprising:
a healing cap blank comprising:
a millable block structured and disposed to be milled by a computer-aided manufacturing machine to form a milled healing cap for congruent receipt of the custom milled abutment component therein; and
a CAM insert member extending from a top end of the millable block, and the CAM insert member is configured to be held by the computer-aided manufacturing machine during milling of the millable block to form the milled healing cap.
3. The customizable single-piece dental implant as recited in claim 1 wherein the millable block is configured to be milled by the computer-aided manufacturing machine to provide a gingival component below the milled shoulderless margin slippage area.
4. The customizable single-piece dental implant as recited in claim 3 wherein the millable block is configured to be milled by the computer-aided manufacturing machine to provide a milled intra-bony component below the gingival component.
