Embodiment
[0035] Such as Figures 1 to 4 shown. The invention discloses an indirect manufacture of a self-locking denture body, which comprises a denture implant 1 and a threaded rod 2 installed therein;
[0036] The implant 1 is a cylindrical structure, its internal diameter gradually decreases from top to bottom, the internal cross-section is in the shape of an inverted cone with a large top and a small bottom, and the inner peripheral wall is an internal thread structure, and the outer wall is distributed with A plurality of protruding structures; the lower part of the cylinder structure is provided with several slits 3 formed by incisions along its axial direction, and the slits 3 cut the lower part of the cylinder structure into a plurality of vanes 5 that can extend radially.
[0037] The threaded rod 2 is a cylindrical structure with equal radius, wherein the lower part has an external thread structure matching the internal thread of the cylindrical structure. When the threaded...

The invention discloses an indirectly-manufactured self-locking type artificial tooth and a method. The indirectly-manufactured self-locking type artificial tooth comprises an artificial tooth implant of a tubular structure and a threaded rod mounted therein, the internal diameter of the tubular structure decreases from top to bottom gradually, the internal section of the tubular structure is in the shape of an inverted taper, the internal circumferential wall of the tubular structure is of an internal thread structure, a plurality of projecting structures are distributed on the surface of the external wall of the tubular structure, and a plurality of slits are formed in the lower portion of the tubular structure and divide the tubular structure into a plurality of valves capable of extending and expanding radially. The indirectly-manufactured self-locking type artificial tooth has the advantages that alveolar bone data and tooth factors are obtained by scanning of an oral cavity of a patient, the individualized implant is designed through three-dimensional modeling software and then is designed secondarily, the threaded rod is designed according to an implant threaded hole, and accordingly the indirectly-manufactured self-locking type artificial tooth with the expanding self-locking function can be mounted inside an alveolar bone firmly. The method is unaffected by complicated shapes of parts and capable of manufacturing individualized fusible patterns in complicated shapes and can be directly used without a traditional machining process.
Description
technical field [0001] The invention relates to the technical field of oral artificial dental implant manufacturing, in particular to an indirect manufacturing self-locking denture body and method. Background technique [0002] Artificial tooth implant is a common treatment for tooth loss at present. It mainly implants a biocompatible metal artificial tooth root into the alveolar bone at the tooth loss, and through the close integration of artificial tooth root and alveolar bone, The artificial tooth root is used as the base for the implant dental model. Since the adjacent teeth are not ground away like fixed dentures, there is no damage to adjacent teeth, and there is no factor for secondary tooth decay, so it is a more stable method than fixed dentures. When a person uses a removable denture due to missing multiple teeth, the periodontal tissue (gum) will be exerted force, so the gum will feel uncomfortable, and the foreign body sensation in the mouth will be severe due t...
