TECHNICAL FIELD

[0001] The present application relates to the technical field of dental implants, and particularly to a denture with a locking structure and a mounting method. BACKGROUND

[0002] The denture is also a dental implant, which generally comprises an implant, an abutment and a crown. During artificial tooth implantation, the implant is first fixed in the alveolar bone, and then the abutment is installed after the implant is tightly combined with the alveolar bone. Finally, the crown is installed on the abutment. Once the implant in the alveolar bone is tightly combined with the alveolar bone, the implantable dental implant can withstand the occlusal force of mastication like a real tooth.

[0003] However, once the implant and the abutment are loose, it is necessary to re-adhere or re-implant, which causes great inconvenience to the patient. SUMMARY

[0004] In order to solve the problem of loose denture, the present application provides a denture with a locking structure and a mounting method.

The first thread 21 is connected with the implant 1, and the second thread 22 is connected with the abutment 3. Since the first thread 21 and the second thread 22 are opposite in rotation direction, after installation, the abutment 3 and the implant 1 can be restricted from each other, so as to avoid loosening of the connection between the abutment 3 and the implant 1 as much as possible. The inner wall of the locking ring 2 is fixed with a filling sheet 23, the filling sheet 23 is arranged between the first thread 21 and the second thread 22, the outer wall of the filling sheet 23 is attached to the inner wall of the locking ring 2, and the middle part of the filling sheet 23 is provided with a through hole 24 for the connecting pipe 33 to pass through.

[0047] With reference to Figure 4 and Figure 5 , four groups of locking assemblies 5 are fixed in the locking groove 11, and the locking assemblies 5 are arranged at intervals around the axis of the locking ring 2.
