[0014] This invention, through the arrangement of a disc, springs, and a connecting seat, allows for adjustment of the rod height according to the implant's position during use. The user can clamp the connecting seat with medical forceps, which moves the fixing post and the moving plate upwards. The moving plate compresses two springs, causing the connecting block to slide within a groove. Once the moving plate reaches the designated position, adjusting the angle of the medical forceps causes the connecting seat, fixing post, moving plate, connecting block, and disc to rotate. The connecting block then rotates within a rotating groove, misaligning with the groove and corresponding to a limiting groove. The medical forceps then release the clamp on the connecting seat, and the spring's return force allows the connecting block to fit tightly against the implant. The height of the moving plate is limited within the limiting groove, and then positioned by the positioning post. The threaded post is then fixed to the implant via threaded connection. Next, the windowed tray is tried on to ensure that the rod and tensioning mechanism can pass through the window. Finally, the tray containing silicone rubber impression material is placed in the oral cavity. After the impression material solidifies, the connecting seat can be rotated with a screwdriver to allow the rod, threaded post, and positioning post to rotate as a whole, releasing the fixation between them and the implant and transfer cap. The windowed tray and transfer cap can then be removed, facilitating height adjustment and avoiding friction or damage to the patient's oral tissues during impression taking due to height issues. The operation is simple, highly flexible, and practical. BRIEF DESCRIPTION OF DRAWINGS
