The micro thread implant includes one conic top with larger upper part and smaller lower part, one conic hole including one octagonal middle part and one lower screw hole part and surface coating of hydroxyapatite. It features the neck with fine thread, the root part with self-tapping straight thread and the conic end, with both the fine thread and the straight thread being saw tooth threads. Thepresent invention has high neck strength, capacity of preventing microbes from invading, easy integrating with bone, easy screwing into the jaw bone and self locking, and may be used in repair dentaldefection, especially false tooth implanting operation.

The invention discloses an oral implant device, comprising alveolar bone, a screw-in body is fixedly installed in the bottom groove of the alveolar bone cavity, and a base is arranged in the alveolar bone cavity on the upper side of the screw-in body, One end of the base away from the screw-in body is provided with a threaded groove, and the inner groove wall of the threaded groove is threadedly connected with a threaded seat. In the device, the bottom end of the implant is fixed on the screw-in body screwed into the alveolar bone through a screw that penetrates deep into the alveolar bone, and hydroxyapatite is filled in the filling cavity provided with the screw at the base of the implant. The connection port is connected with the filling cavity and the alveolar bone cavity, so as to ensure the stable installation of the implant in the alveolar cavity cavity and avoid loosening; the device flexibly clamps the clamping plate on the installation seat with the denture Between the lifting plate and the clamping plate, it can flexibly install and replace the denture without moving the lower part of the implant denture, avoid secondary injury to the patient, and improve the work efficiency of medical staff.

The invention discloses an implant denture individual abutment design method based on a healing abutment dental model, and belongs to the field of computer auxiliary design. The method comprises the following four steps: acquiring and preprocessing data; establishing an implant system model base; positioning a healing abutment and an implant body; and designing an individual abutment. The implantdenture individual abutment design method is high in automation, not only ensures that the operation steps of manufacturing a wax pattern or casting a model, and transferring the implant body on clinic and the like can be omitted, but also can be used for improving the shape of gingival margin of the restored implant denture, greatly reducing the operation time and cost of a doctor and a skilled work, and improving the restoration efficiency and beautiful appearance; the implant denture individual abutment design method based on the healing abutment dental model has important application value in a computer auxiliary dental implant field.

The invention relates to an automatic CAD / CAM / 3D processing method of dental prostheses. The method comprises the step of processing dental prostheses by employing a composite system composed of an optical scanner and a computer aided design system, a CAD / CAM aided system, a selective laser cladding machine and a numerical control cutting machine tool, wherein prostheses such as removable partial dentures, fixed dentures, complete dentures and implant dentures can be rapidly manufactured. The method is characterized in that numerical control cutting (subtractive manufacturing called as subtraction) and the 3D printing technology (additive manufacturing called as addition) are organically combined and highly unified. Two aspects of the unity and opposites are merged into one uniform aspect; the automatic production efficiency of the dental prostheses, especially complex prostheses, can be greatly improved, complicated procedures of a conventional handmade dental prosthesis are eliminated, the manufacturing quality and stability of the prostheses are improved, the purposes of quickness, accuracy and individualized manufacturing are achieved, and the dental prostheses meet the urgent demands of most agomphosis patients.

The invention discloses a detachable implant denture and a utilization method thereof. The denture comprises an outer denture, an inner mesh and a film, the film sleeves the inner mesh which is provided with side wall holes, the bottom of the inner mesh is provided with reinforcing ribs, and the back face of the inner mesh is provided with convex points. An outer shell is provided with inner meshclamping fasteners, the side wall of the outer shell of the outer denture is formed by a closed structure, the bottom of the outer denture is additionally provided with concave pits peripherally, theinner wall of the outer denture is additionally provided with clamping fasteners, and the bottom of the outer denture is provided with reinforcing ribs. A method for making artificial teeth by use ofthe denture mainly includes steps: connecting the film, the inner mesh and the outer denture, coating the film with a modeling material, and allowing a patient to bite the denture, wherein in occlusion, an implant of the patient needs to penetrate the film to leave an evident mark on the inner mesh; making matched artificial teeth according to occlusion images of the inner mesh film in the denture. The implant denture is convenient to demount, an implant base is capable of penetrating the film in operation, and accuracy and cleanness in denture removal are achieved while material overflowing is avoided; high universality is realized, and repeated denture wearing times of the patient can be reduced in operation of a dentist so as to make the patient comfortable.
