Double-sided fusion connected dental implant assembly

Abstract

The invention discloses a double-sided fusion connected dental implant assembly, which comprises: an implant, wherein the top of implant is provided with a mounting hole, the inner wall of the top end of the mounting hole is provided with a first inner conical surface, and the implant is provided with a threaded hole; a base table, wherein a first outer conical surface is arranged on the outer wall of the base table, the first outer conical surface is attached to the first inner conical surface, an assembly hole is formed in the base table, a second inner conical surface is arranged on the inner wall of the assembly hole, and the conical angle of the second inner conical surface is equal to that of the first inner conical surface; and a central screw, wherein a screw rod is arranged at the bottom end of the central screw, the screw rod is connected with the threaded hole in a matched mode, a second outer conical surface is arranged on the outer wall of the central screw, and the second outer conical surface is attached to the second inner conical surface. According to the double-sided fusion connected dental implant assembly, cold pressure welding is ensured to be formed between the second outer conical surface and the second inner conical surface, so that double-sided fusion connection is formed among the implant, the abutment and the central screw, and the sealing performance of the dental implant assembly is favorably improved. The dental implant assembly can be applied to tooth implantation.

Description

technical field [0001] The invention relates to the field of dental implants, in particular to a double-sided fusion-connected dental implant assembly. Background technique [0002] The dental implant component includes an implant, an abutment, and a central screw. The implant is implanted in the alveolar bone of the oral cavity, and the abutment is locked to the implant by the central screw. At present, there is a sealed fit connection between the implant and the abutment, and a sealed fit connection between the central screw and the abutment, so as to prevent microorganisms or liquids in the oral cavity from entering the interior of the dental implant. [0003] Usually, the abutment and the implant are fitted with a conical surface, and the central screw locks the abutment to the implant, exerting pressure to make the abutment and the implant closely contact, and after a long period of action, the abutment and the implant will The contact surface forms a cold pressure wel...

AI Technical Summary

Problems solved by technology

However, due to the large difference between the pressure on the contact surface between the central screw and the abutment and the pressure on the contact surface between the abutment and the implant, the contact surface between the central screw and the abutment cannot form cold pressure welding, making The sealing performance of dental implant components is greatly reduced
