Description

Technical Field

[0001] The utility model relates to the technical field of tooth implantation, in particular to an edentulous jaw implantation impression transfer rod. Background Art

[0002] When implanting in the edentulous jaw, the implant impression technique is used for taking the impression. This technique can be divided into open window impression method and closed window impression method. Both methods use the tray of impression transfer rod and oil-proof silicone impression gear to make the intraoral impression.

[0003] The open window impression method involves fixing the impression post to the implant with a central screw. A tray with a pre-cut hole corresponding to the implant location is then placed on top of the mixed silicone rubber impression material. While the tray is placed in the mouth, the tail end of the central screw is passed through the tray's opening. Once the silicone rubber impression material has hardened, the exposed screw tail is loosened with a screwdriver. The transfer post, along with the hardened impression material and tray, is then removed, completing the impression. The closed window impression method does not require drilling a hole in the tray. The hardened impression material and tray are removed, and the transfer post is then removed and placed back into the hardened impression material.

[0004] In clinical practice, the closed-window impression method is more convenient and is therefore currently the most commonly used method for impression taking. When using the closed-window impression method, the implant must be mounted on a press, a transfer rod must be installed on the implant, and then the impression is taken using a silicone impression tray. However, the transfer rod currently used is prone to rotation during impression taking, and this rotation directly affects the accuracy of the impression.

[0005] In response to the above problems, the present utility model document proposes an edentulous jaw implant impression transfer rod. Utility Model Content

The transfer rod body is a columnar structure with a positioning groove at its bottom end and a mounting hole at its top end. The mounting hole is connected to the bottom of the positioning groove. A connecting rod is provided on the side wall of the transfer rod body near the top end.

[0009] Furthermore, a side wall in the middle of the transfer rod body is provided with an annular anti-rotation groove.

[0010] Furthermore, a slot is provided on the side wall of the transfer rod body, and a block matching the slot is provided on the end of the connecting rod. The connecting rod is connected to the transfer rod body through the block and the slot.

[0011] Furthermore, an annular limiting plate is provided at the opening of the clamping slot, and a limiting slot that matches the limiting plate is provided at the connection between the clamping block and the connecting rod.

[0026] Example:

[0027] Reference Figure 1 、 Figure 2 and Figure 3As shown, a transfer rod for edentulous implant impression taking includes a transfer rod body 1. The transfer rod body 1 is a columnar structure with a positioning groove 101 at the bottom end and a mounting hole 102 at the top end. The mounting hole 102 is connected to the bottom of the positioning groove 101, and a connecting rod 2 is provided on the side wall of the transfer rod body 1 near the top end.

[0028] The transfer rod body 1 is placed on the implant base through the positioning groove 101 at the bottom, and the mounting hole 102 at the top is connected to the positioning groove 101, so that the bolt can pass through the mounting hole 102 and cooperate with the implant base, and the transfer rod body 1 is fixed to the base through the mounting hole 102 at the top with the bolt, and the connecting rod 2 on the side wall of the transfer rod body 1 can be connected to the adjacent connecting rod 2, thereby preventing the transfer rod body 1 from rotating, thereby avoiding the influence of the transfer rod rotation on the silicone mold, and improving the accuracy of the silicone mold.

[0029] An annular anti-rotation groove 103 is provided on the side wall of the middle portion of the transfer rod body 1 .

[0030] The anti-rotation groove 103 further increases the rotational torque between the transfer rod body 1 and the silicone mold, while increasing the adhesion of the silicone to the transfer rod body 1, effectively preventing the transfer rod body 1 from rotating, thereby avoiding the transfer rod body 1 rotating and affecting the accuracy of the silicone mold.

[0031] The side wall of the transfer rod body 1 is provided with a slot 104 , and the end of the connecting rod 2 is provided with a block 201 matching the slot 104 . The connecting rod 2 is connected to the transfer rod body 1 through the block 201 and the slot 104 .

[0032] The connecting rod 2 is installed on the transfer rod body 1 through the card slot 104 and the card block 201, so that the connecting rod 2 can be removed, which is convenient for replacing connecting rods 2 of different lengths according to the distance between adjacent transfer rod bodies 1, ensuring that the connecting rods 2 on adjacent transfer rod bodies 1 can be connected, thereby fixing the transfer rod body 1.

[0033] An annular limiting plate 105 is provided at the opening of the clamping slot 104 , and a limiting slot 203 that matches the limiting plate 105 is provided at the connection between the clamping block 201 and the connecting rod 2 .

[0034] After the block 201 on the connecting rod 2 is inserted into the slot 104, the limiting plate 105 at the opening of the slot 104 is locked in the limiting groove 203, thereby preventing the block 201 from falling off from the slot 104, thereby preventing the connecting rod 2 from falling off from the transfer rod body 1, and ensuring the fixing effect of the connecting rod 2 on the transfer rod body 1.

[0035] The slot 104 is communicated with the mounting hole 102 .

[0036] On the one hand, it is easy to process, and on the other hand, it is also convenient for the card block 201 to fit closely with the card slot 104 , thereby preventing the card block 201 from being unable to be inserted into the card slot 104 due to excessive air pressure in the card slot 104 .

[0037] A liquid storage tank 202 is formed on the outer side wall of the connecting rod along the length direction of the connecting rod.

[0038] Adhesive is stored in the liquid storage tank 202 , and when in use, the sides of adjacent connecting rods are connected and fixed by the adhesive, thereby fixing the transfer rod body 1 , making the length of the connecting rod 2 more flexible to use and improving the adaptability of the connecting rod 2 .

[0039] The outer side wall of the top end of the transfer rod is provided with a plurality of flat surfaces 106 .

[0040] A plurality of planes 106 are provided on the outer side wall of the top end of the transfer rod to improve the adhesion of the silicone to the transfer rod, thereby improving the mold taking accuracy of the silicone.

[0041] During use, the doctor selects a connecting rod 2 of appropriate length according to the distance between adjacent transfer rod bodies 1, clamps the transfer rod body 1 on the implant base through the positioning groove 101 at the bottom end, and then passes the bolt through the mounting hole 102 to thread it with the implant base, thereby fixing the transfer rod body 1 on the implant base, making the sides of the connecting rods 2 on adjacent transfer rods contact, and adding adhesive in the liquid storage tank 202, and connecting and fixing the adjacent connecting rods 2 through the adhesive, so that the connecting rods 2 cannot rotate, thereby making the transfer rod body 1 unable to rotate, and then placing silicone on the position of the implant base on the dental tray, and then placing the dental tray in the patient's mouth, inserting the silicone into the transfer rod body 1, and waiting for the silicone to cool and solidify to form a crown model.

[0042] In actual use, multiple liquid storage grooves 202 are evenly opened on the side wall of the connecting rod 2, which facilitates the connection of the connecting rod 2 from different directions and angles without frequently rotating the connecting rod 2 and affecting the stability of the transfer rod body 1.

[0043] The transfer rod of the utility model can improve the adhesion force between the silicone and the transfer rod while effectively preventing the transfer rod from rotating, thereby improving the accuracy of the crown model formed by the silicone.

[0044] The utility model has the advantages of simple structure, convenient use and suitable for promotion.

[0045] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this utility model should be included in the scope of protection of the present utility model.
