Problems solved by technology

However, the screw-fixed connection method is prone to shortcomings such as screw loosening, breaking, unsightly appearance, poor tread shape, and micro-gap between the abutment and the restoration crown.
The cemented fixed connection method has requirements on the application method and amount of cement. It is necessary to coat the contact surface of the abutment and the restoration crown with cement. If the amount of cement is insufficient, the use of the restoration crown will be shortened. life, if the amount of cement is too much, it will overflow and cause pollution

Abstract

The invention discloses a zirconia base station comprising a gum piercing section, a neck section and a connecting section, and the neck section is located between the gum piercing section and the connecting section, and has a platform for supporting a peripheral repaired crown. The connecting section is a cylinder, the side of the connecting section is provided with an automatic locking device, the automatic locking device comprises a circular arc-shaped sliding passage and a locking member, openings at the two ends of the sliding passage are located on the same vertical line on the side of the connecting section, the locking member is slidably coupled to the sliding passage, the arc length of the locking member is greater than the arc length of the sliding passage, and the bottom end ofthe locking member is a streamlined curved surface. The zirconia base station can automatically deform and expand, can tension the repaired crown from the inside without using screws to achieve stableconnection of dental implants when sleeving the repaired crown by additional arrangement of the automatic locking device.

Description

technical field [0001] The invention relates to the technical field of dental implants, in particular to a zirconia abutment. Background technique [0002] Existing dental implants mainly include implants, abutments and restoration crowns. Abutments provide retention, support and stability for a prosthetic crown. There are two existing abutment connection methods, which are ①Screw-fixed connection of the abutment: that is, the connection between the abutment and the restoration crown is fixed and repaired by screws; The joints are repaired with cement fixation. However, the screw-fixed connection method is prone to shortcomings such as screw loosening, breaking, unsightly appearance, poor tread shape, and micro-gap between the abutment and the restoration crown. The cemented fixed connection method has requirements on the application method and amount of cement. It is necessary to coat the contact surface of the abutment and the restoration crown with cement. If the amoun...
