Abstract

The invention relates to an assembled dental implant, and belongs to the technical field of dental implantation. The assembled dental implant is applicable to patients who suffer tooth decay, snaggletooth and periodontal disease, need to be surgically treated, and need tooth implantation after teeth are absent. The assembled dental implant comprises an implanting screw and an assembled base platform, and is assembled by the implanting screw and the assembled base platform; a conical threaded section is formed outside the implanting screw, and the end surface of a cylinder is provided with a plurality of dentiform protuberances or grooves of the implanting screw; the assembled base platform comprises a base platform body, a connecting screw and a thread bushing, the upper part of the base platform body is provided with an artificial tooth connection part, the middle part of the base platform body is provided with a transgingival part, the lower part of the base platform body is provided with an implanting screw connection part, and the assembled base platform is arranged in the implanting screw; the lower end surface of the transgingival part is provided with a plurality of dentiform grooves or protuberances of the base platform body which are matched with the dentiform protuberances or grooves of the implanting screw; and the thread bushing is matched with an internal thread of the implanting screw and is used for connecting the assembled base platform with the implanting screw.

Description

technical field [0001] The invention relates to an assembled dental implant, belonging to the technical field of dental implants. It is suitable for patients with tooth decay, broken teeth, periodontal disease, surgical treatment, and dental implants after tooth loss. Background technique [0002] Modern dental implant technology has developed into an independent research category in mature stomatology supported by multi-disciplinary cutting-edge technologies, and has established a new concept and method that is more scientific, reasonable and perfect. The traditional way of filling teeth is to make braces, which also have a certain image on both sides of the teeth. The current dental implants repair and repair the loss of the patient's natural tooth root, and play a very good role in restoring function. Therefore, it is necessary to provide a good base for tooth implantation. The outside of the implant is a helical structure, which is fixed in the alveolar bone throug...
