Description

Healing screw curette

This creation relates to a healing screw curette, and in particular to a related device for removing a healing screw.

In dental medicine, for dental implants, an implant is implanted into the alveolar bone of the tooth, and a base is fixed on the implant, and the artificial crown is fixed on the outer side of the abutment to restore the tooth. The function and expect to be used permanently. In the above-mentioned dental implant surgery, a hole is drilled into the alveolar bone by using a drill to serve as a screwing position of the implant, and the implant is implanted and integrated with the alveolar bone to perform the tooth again. The meat is turned over and the artificial crown is placed on the implant.

In the current stage of planting two-stage implants, in order to improve the success rate of the operation, the method of burying is often used to connect the abutments in the second stage; in this process, the gingiva is cut by local anesthesia. Remove the healing screw and replace it with a healing abutment; in this process, if the minimally invasive method is used, it will cause difficulty in removing the healing screw. At present, the solution to the above problems generally adopts three methods: 1 using a gingival ring cutter, directly removing the gingival tissue at the top of the implant, and screwing out the healing screw under direct vision, and replacing it with a healing abutment. 2 The same incision method as the implant surgery is used to separate the gums, replace the healing screws as the healing abutment, and then suture the wound. 3 cut directly above the screw hole and the diameter of the healing abutment A similar incision is made to detect the healing screw and then unscrewed, and then screwed into the healing abutment according to the original channel, and the gingival dent is formed. However, there are some problems in the above-mentioned schemes. For example, the use of a gingival ring cutter will lose some of the keratinized gingiva, and the risk of gingival tissue deficiency will increase in the non-aesthetic area, causing a black triangle and aggravating the original food impaction. At the same time, in the area of the aesthetic school, keratosis is often insufficient, and the loss will have a certain impact on the reconstruction of red aesthetics in the future; the same method as the implant surgery can be used to remove the healing screw under direct vision. According to the method of re-entering the original surgical incision, the wound is large and needs to be re-stitched, resulting in an increase in cost; the small incision takes the screw, avoiding the disadvantages of the first two. However, because of the blockage of the keratinized tendon, it is difficult to find the healing screw. Moreover, the removal process needs to overcome the resistance of the gums. At present, a small curette is used to hook the edge of the healing screw cap and pull it out of the gingival tissue, but this sharp instrument that is not the same material as the implant is inadvertently used during use, and is easy to produce on the transfer platform of the implant. Injury is not conducive to long-term care of the tissues surrounding the implant.

In view of this, in order to overcome the aforementioned problems, there is an urgent need for a simpler, more accurate and more convenient surgical aids, which will help in the surgical process.

The main purpose of this creation is to improve the problems encountered in the aforementioned dental implant process, and to provide a curette structure. The curette of the present invention comprises a hemispherical working end of the front end, and a neck rod extends vertically upward at a flat end of the hemispherical working end, and the end of the neck rod is extended with a suitable curvature to form a grip end for providing a person's grip.

The curette can be made of titanium alloy, carbon fiber, polymer material, stainless steel.

Shape, size, proportion, or number of components, etc., are a selective design; all words about front, back, left and right, up and down, and horizontal or vertical are used for convenience of description, not limiting the creation, nor Its components are limited to any position or spatial direction;

The creation structure and the efficacies that can be achieved are as follows: First, please refer to the three-dimensional structure diagram of the preferred embodiment of the present invention as illustrated in the first figure. As shown in the figure, the present invention is a curette 10 comprising a hemispherical working end 11 at the front end, and a neck 12 extending upward from the flat end of the hemispherical working end 11, the end of the neck 12 being at an appropriate curvature Extending to form the grip end 13 and providing When the person is holding, the hemispherical working end 11 and the neck rod 12 are in accordance with the angle of the operation. Preferably, all or at least the hemispherical working end 11 and the portion of the neck 12 of the curette 10 may be made of titanium alloy, carbon fiber, polymer material, or stainless steel.

Please refer to the schematic diagram of the use of the present embodiment shown in the second to sixth figures. According to the description of the above-mentioned creation structure, after the small incision probes the healing screw 21 of the implant 20, the healing screw 21 is rotated by the screwdriver A. To dislocate, the hemispherical working end 11 of the front end of the curette 10 is swept from the gingival incision, and the healing screw 21 is caught under the edge of the top of the gum and healing screw 21, and the screw cap is gradually pulled upwards counterclockwise. Pulling, the healing screw 21 can be removed from the gingival incision.

In this way, the creation of the curette 10 can achieve the following gains: the creation is simple and convenient, after the screwdriver A spins the healing screw 21 of the implant 20, the hemisphere of the curette 10 is utilized by the flexibility of the gum tissue. The working end 11 is pressed into the gap between the gum and the top cap of the healing screw 21. Since the hemispherical working end 11 is a titanium hemisphere, there is no damage to the edge of the platform where the combined long epithelium and implant have been formed; the plane bulging using the hemispherical working end 11 is formed below the edge of the healing screw 21 The card is hung, and while the screw is pulled upward, the hemispherical working end 11 is kept in contact with the lower edge of the healing screw 21, and the heel is rotated around the healing screw 21 counterclockwise. Further, since the neck rod 12 slides between the gums and the screw cap, the frictional force is reduced, so that the screw cap is smoothly taken out, the operation time is shortened, the surgical suture is saved, and the pain of the patient is reduced.
