Embodiment Construction

[0019] Such as Figure 1-Figure 5 As shown, the easy-to-access oral impression transfer device includes an impression transfer rod 1, an impression transfer body 2, an elastic wire 4, and a bolt 5. The bottom of the impression transfer body 2 is provided with a positioning boss, and the impression transfer body 2 has a rod hole inside, and a threaded hole is opened on one side of the impression transfer body 2. One end of the elastic metal wire 4 is fixed on the impression transfer rod 1. It can be a metal wire fixing hole on the impression transfer rod 1, elastic metal One end of the wire 4 passes through the wire fixing hole and is wound and fixed on the impression transfer rod 1. Alternatively, one end of the elastic metal wire 4 is welded to the impression transfer rod 1, and the elastic metal wire 4 is wound around the impression transfer rod 1. Wrap several times in the radial direction, the impression transfer rod 1 is placed in the rod hole of the impression transfer bo...

Abstract

The invention discloses an easily-extracting type oral impression transfer device. A positioning lug boss is arranged at the bottom of an impression transfer body; one head of an elastic metal wire is fixed on an impression transfer rod, the elastic metal wire is radially wound for a plurality of circles along the impression transfer rod, the impression transfer rod is arranged in a rod hole of the impression transfer body, and the other head of the elastic metal wire is fixed on the inner wall of the impression transfer body; and a bolt is in threaded connection with a threaded hole of the impression transfer body, and the end part of the bolt supports against the outer wall of the impression transfer rod. The easily-extracting type oral impression transfer device disclosed by the invention can be used for effectively solving the problems of low opening degree, difficult rotation of the impression transfer rod in a vertical direction, inconvenience for doctor operation and inaccuracy in impression extraction by adopting a structure on which two heads of the elastic metal wire are respectively fixed on the impression transfer rod and the impression transfer body and the impression transfer rod is fixed through the bolt, is low in manufacturing cost, and can be used for greatly improving the operation efficiency of a doctor, preventing the doctor-patient dispute caused by inconvenience for operation, reducing the pain of a patient and impelling the development of an oral implanting technology.

Description

Technical field [0001] The invention relates to the technical field of oral implantation, and in particular to an easy-to-take oral impression transfer device and a mounting and taking method thereof. Background technique [0002] Implant denture restoration includes a series of processes such as the formulation of implant plan, implant placement, implant transfer impression, denture production, try-on and insertion and maintenance after implant restoration. Obtaining accurate impressions and working models of implant relationship transfer is the basis of denture production. [0003] Dental implant surgery is particularly important to make the restoration according to the tooth shape of the surgical object and to locate the restoration in an accurate position. Therefore, the shape of the tooth of the surgical object is printed with the impression material to make an accurate tooth model, and the most accurate restoration is made with this model To perform the actual surgery.
