The denture body 1 can be replaced individually during use without the need for simultaneous removal and replacement of the tooth root body 6. At the bottom port of the connecting groove 2 and at the bottom of the denture body 1, there is a tooth root sleeve 4 for external protection and positioning of the tooth root connecting block 3. The tooth root sleeve 4 is located at the bottom of the connecting groove 2 and can provide positioning and protection for the tooth root connecting block 3 after it is connected to the denture body 1. The tooth root sleeve 4 is externally provided with an outer sheath 5 for protecting the outer surface of the tooth root sleeve 4 after denture implantation. The outer sheath 5 is located outside the tooth root sleeve 4 to protect the tooth root connecting block 3 and prevent friction between it and the gums. The tooth root connecting block 3 is positioned and connected to the tooth root body 6 with an external threaded surface at its bottom, so that the denture body 1 can be implanted on the tooth root in the oral cavity, and the tooth root body 6 does not need to be disassembled when the denture body 1 is removed and replaced.

[0023] The tooth root body 6 has a dental groove 7 with an internal hexagonal structure at the center of its end, which fixes the tooth root connecting block 3 to the tooth root body 6. The bottom of the outer sleeve 5 has an anti-loosening ring 8 that fits onto the tooth root body 6, so that the anti-loosening ring 8 is positioned and fitted onto the outside of the tooth root body 6. The inner side of the anti-loosening ring 8 has an anti-loosening locking ring 9 with internal threads. The anti-loosening locking ring 9 is screwed onto the tooth root body 6 at the same time as the dental prosthesis body 1 and the tooth root connecting block 3 are screwed together to prevent loosening and lock it in place, thereby strengthening the connection stability between the two.

[0024] The tooth root connecting block 3 has a threaded connection part 10 on its upper outer side, which allows the denture body 1 to be screwed to one end of the tooth root connecting block 3, so as to facilitate the removal and replacement of the denture body 1 later. The tooth root connecting block 3 is threadedly fixed in the connecting groove 2 at the bottom of the denture body 1 through the threaded connection part 10, thereby fixing the denture body 1 and the tooth root connecting block 3. The bottom center of the tooth root connecting block 3 is provided with an anti-loosening positioning post 11 to enhance the anti-loosening stability between the tooth root connecting block 3 and the tooth root body 6. The anti-loosening positioning post 11 has an external hexagonal structure.
