Description

Technical Field

[0001] The utility model belongs to the field of dental implantation, in particular to a special installation tool for a composite base. Background Art

[0002] When installing the composite abutment for the second-stage dental implant surgery, since the central through hole of the composite abutment is not concentric with the screw hole on its head but at a certain angle, when connecting the abutment and the implant with the central screw, first ensure that the central screw hole is concentric with the threaded hole of the implant. Considering the extremely small size of the composite abutment itself, a metal rod needs to be screwed into the open thread of the composite abutment head during the transfer process. The metal rod is held to clamp the hexagon of the composite abutment into the corresponding hexagonal groove of the implant. After the hexagonal groove is clamped, the central screw is screwed in. Since the effective connection length between the composite abutment and the implant is short, the installation of the composite abutment on the implant is not yet tightened. The composite abutment is prone to loosening and falling off during operation. To avoid this phenomenon, when screwing in the central screw with a screwdriver, the other hand needs to participate in the whole process to press the composite abutment tightly to prevent movement, so that the composite abutment fits tightly on the implant until the composite abutment is installed.

[0003] The existing technology is limited by the small oral environment, resulting in insufficient operating space, the target object (central screw) to be screwed in is too small, and the screw is inconvenient to position. In addition, since the operation process requires both hands to apply force at a certain angle, the phenomenon of uneven force cannot be avoided, which can easily cause the composite base to swing back and forth in the hexagonal slot. The screwing in of the screws during operation is relatively blind, which is time-consuming, and the long-term operation with both arms suspended in the air causes arm soreness, which gives doctors and patients a poor experience. Utility Model Content

[0004] In view of this, the utility model aims to propose a special installation tool for a composite abutment, which allows the doctor to screw in the central screw with one hand. The operation is much more convenient and provides a better experience for doctors and patients than before the improvement. After the composite abutment and the installation tool are fixed on the implant as a whole, only the screwdriver and the central screw are in a state of being movable up and down. The central screw can be screwed into the thread inside the implant by pinching the tail of the screwdriver with one hand, and the overall operation difficulty is greatly reduced.

[0005] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0006] The special installation tool for the composite base has a cone-shaped structure as a whole. The top of the installation tool is provided with a No. 1 port, and the bottom is provided with a No. 2 port. The No. 1 port is set at the large round end, and the No. 2 port is set at the small round end.

[0007] The first port and the second port are connected via a mounting through hole; the second port is used for fixing the composite base;

[0008] The installation tool is also provided with a No. 1 through hole, a No. 2 through hole and a safety through hole which do not interfere with each other;

[0009] The No. 1 through hole and the No. 2 through hole are used to insert screwdrivers, and the No. 1 through hole and the No. 2 through hole correspond to the central through hole of the composite base; the central screw can enter the central through hole of the composite base through the No. 1 through hole or the No. 2 through hole; the mounting through hole corresponds to the threaded hole on the head of the composite base and is used to insert the metal rod.

[0010] Furthermore, the angle between the No. 1 through hole and the axis of the installation tool is 17°, and the angle between the No. 2 through hole and the axis of the installation tool is 30°.

[0011] Furthermore, the safety through hole is used to set a safety rope to prevent it from falling off.

[0012] Furthermore, the second opening is trumpet-shaped, which fits with the head of the composite base and can fix the head of the composite base.

[0013] Compared with the prior art, the composite base installation tool described in the utility model has the following advantages:

[0014] The utility model of the special installation tool for the composite abutment is intended to improve the problem of difficulty in screwing in the central screw or even the falling off of the composite abutment due to the uneven force caused by two-handed operation. The two-handed operation is largely limited by the small oral environment and is not convenient enough. While the right hand is screwing in the central screw, the left hand also needs to keep exerting force. Long-term operation in the air causes arm soreness, which greatly reduces the experience of both doctors and patients. With the improved structure, the doctor can screw in the central screw with one hand. Compared with the operation before the improvement, the convenience and experience of doctors and patients are greatly enhanced. After the composite abutment and the installation tool are fixed on the implant as a whole, only the screwdriver and the central screw are in a movable state. You can pinch the tail of the screwdriver with one hand to screw the central screw into the thread inside the implant, and the overall difficulty of operation is greatly reduced.

[0026] The special installation tool for the composite base has a cone-shaped structure as a whole. The top of the installation tool 1 is provided with a No. 1 opening 2, and the bottom is provided with a No. 2 opening 3. The No. 1 opening 2 is set at the large round end, and the No. 2 opening 3 is set at the small round end;

[0027] The first opening 2 and the second opening 3 are connected via a mounting through hole 4; the second opening 3 is used to fix the composite base 10;

[0028] The installation tool 1 is also provided with a first through hole 5, a second through hole 6 and a safety through hole 7 which do not interfere with each other;

[0029] Through hole No. 1 5 and through hole No. 2 6 are used to insert the screwdriver 8, and through hole No. 1 5 and through hole No. 2 6 correspond to the central through hole 102 of the composite base 10; the central screw 12 can enter the central through hole 102 of the composite base 10 through through hole No. 1 5 or through hole No. 2 6; the mounting through hole 4 corresponds to the head threaded hole 101 of the composite base 10, and is used to insert the metal rod 9.

[0030] Preferably, the angle between the No. 1 through hole 5 and the axis of the installation tool 1 is 17°, and the angle between the No. 2 through hole 6 and the axis of the installation tool 1 is 30°;

[0031] The angles between the threaded hole 101 on the head of the composite base 10 and the central through hole 102 are generally 17° and 30°. In order to adapt to two different base specifications at the same time, through holes with angles of 17° and 30° are respectively opened on the opposite sides of the installation tool 1; according to the angle type of the installed composite base 10, the corresponding through hole is selected to insert the screwdriver 8.

[0032] Preferably, the safety through hole 7 is used to set a safety rope to prevent it from falling off. The safety rope is passed through the hole before operation to prevent the installation tool 1 from falling into the deep of the patient's mouth due to careless operation.

[0033] Preferably, the second opening 3 is trumpet-shaped, which fits with the head of the composite base 10 and can fix the head of the composite base 10 .

[0034] Method of use: before the composite abutment 10 is installed on the implant 11, take out the composite abutment 10 installation tool 1 and insert the head of the composite abutment 10 into the No. 2 opening 3 at the end of the installation tool 1, rotate the installation tool 1 so that the installation through hole 4 of the No. 1 through hole or the No. 2 through hole of the installation tool 1 is in a concentric state with the central through hole 102 of the composite abutment 10, and the central screw 12 passes through the installation tool 1 and the composite abutment 10 at the same time, and then the screwdriver 8 is also inserted into the hole of the central screw 12;
