AI Technical Summary
The existing connection structure between dental crowns and implant abutments requires multiple disassembly and assembly with a screwdriver during the fitting process, which is inefficient, cumbersome, prone to thread wear, tool contamination, or screw loss, and makes it difficult to achieve a reliable temporary connection without using screws, resulting in a poor user experience.
The device employs a claw-type connection structure, including a clasp groove on the implant abutment and a claw assembly on the crown sleeve. The claw assembly matches and extends into the clasp groove to achieve a detachable connection between the crown sleeve and the implant abutment. The claws, made of elastic material, are secured within the clasp groove, eliminating the need for screw removal and simplifying the operation.
It improves the efficiency of the trial fitting process, simplifies the operation procedure, ensures positioning accuracy and ease of removal, adapts to the high-frequency desorption requirements in digital processes, and enhances the patient's user experience and repair effect.
