[0023] The instruments, reagents, materials, etc. involved in the following embodiments, unless otherwise specified, are all conventional instruments, reagents, materials, etc. in the prior art and can be obtained through regular commercial channels. The experimental methods, detection methods, etc. involved in the following embodiments, unless otherwise specified, are all conventional experimental methods, detection methods, etc. in the prior art.

[0024] Embodiment 1:

[0025] This example uses a detachable group device support component, including an implant screw 1 and a positioning seat.

[0026] The implant pin 1 is used to be placed in the gums of edentulous patients. One end of the implant pin 1 is provided with a conical tip 2, and the other end is provided with a circular mounting end surface 3. After being implanted in the gums, the mounting end surface 3 does not exceed the height of the gum mucosa and does not affect the patient's mouth closing and chewing.

[0027] The implant nail 1 is provided with external threads all around, which is used to facilitate the operation during the implantation operation and to cooperate more firmly with the gums.

[0028] A matching groove 4 is centrally disposed on the installation end surface 3 . The matching groove 4 is a sunken groove coaxially centered with the implant nail 1 . The matching groove 4 has a circular notch on the installation end surface 3 .

[0029] The positioning seat includes a cylindrical cap head 5, and the top end surface of the cap head 5 is provided with an arc chamfered corner. The more rounded structure reduces the irritation to the mucous membrane. A plug post 6 integrally formed with it is fixed in the center of the bottom surface of the cap head 5, and the plug post 6 is movably plugged into the matching groove 4.

[0030] This assembly uses a detachable and combinable implant structure to first place an implant pin 1 in the edentulous jaw corresponding to the gums to achieve positioning of the raised position, and then the guide plate is positioned through the cap head 5 of the positioning seat through the anchor pin. This does not affect the matching accuracy, nor does it affect the patient's oral health during the waiting period.

[0031] Embodiment 2:

[0032] This example uses a detachable group device support component, including an implant screw 1 and a positioning seat.

[0033] The implant nail 1 is used to be placed in the gums of edentulous patients. One end of the implant nail 1 is provided with a conical tip 2, and the other end is provided with a circular mounting end surface 3.

[0034] The implant nail 1 is provided with external threads all around, which is used to facilitate the operation during the implantation operation and to cooperate more firmly with the gums.

[0035] A matching groove 4 is provided in the center of the installation end surface 3, and the matching groove 4 is a sunken groove coaxially centered with the implant nail 1. The matching groove 4 has a circular notch on the installation end surface 3, and the matching groove 4 includes a guide opening 7 and a thread groove 8 from the notch to the bottom of the groove. The notch is located at the top of the guide opening 7, and the guide opening 7 is a conical structure with a larger top and a smaller bottom, which can facilitate assembly and insertion, and quickly guide the threaded matching below. The bottom end of the guide opening 7 is smoothly connected with the thread groove 8 through an arc chamfer, and an internal thread is provided in the thread groove 8.

[0036] The positioning seat includes a cylindrical cap head 5, and the top end surface of the cap head 5 is provided with an arc chamfered circumferential side. The relatively rounded structure reduces the stimulation to the mucosa. A plug post 6 integrally formed therewith is fixed in the center of the bottom surface of the cap head 5. The upper part of the plug post 6 is adapted to the guide port 7, and is a conical structure with a larger upper part and a smaller lower part. The lower part of the plug post 6 is a straight column and is threadedly connected to the threaded groove 8. By inserting the plug post 6 into the matching groove 4 and rotating and tightening it, the positioning seat can be tightly and precisely fixed on the implant pin 1, thereby achieving the matching with the corresponding card slot of the guide plate. The threaded connection at the bottom can fix the positioning seat well. For patients with soft gums, thick soft tissues, or poor self-control, this structure can ensure accurate positioning during the use and shooting of the guide plate.

[0037] Through the detachable and combinable implant structure, the implant pin 1 is first placed in the edentulous jaw gum, and the installation end surface 3 is placed below the gum height near the implant position. When positioning with the guide plate is required, the positioning seat is installed on the top of the implant pin 1. This will not affect the matching accuracy, nor will it affect the patient's oral health during the waiting period.

[0038] Embodiment 3:

[0039] Based on the design of the combined support assembly, when one side is exposed in the oral cavity, food debris or other oral secretions may accumulate in the matching groove 4, which can be rinsed with a water flosser, but it is a bit troublesome. If the matching groove 4 structure based on embodiment 2 has a threaded part at the bottom, it is difficult to clean thoroughly.

[0040] This example further includes a covering member based on the implant nail 1 and the mounting seat in Example 2;

[0041] The covering member is made of silicone rubber and includes a plug 9. The plug 9 is adapted to the guide port 7 and is a truncated cone of the same shape. A cover sheet 10 formed integrally therewith is provided on the top of the plug 9. The cover sheet 10 is circular and has a diameter larger than the diameter of the slot, so that the cover sheet 10 can cover the slot. The size of the cover sheet 10 is adapted to the size of the mounting end face 3 and can be slightly smaller than the mounting end face 3, so that the cover sheet 10 is mainly exposed in the oral cavity. Since the cover sheet 10 is made of silicone, it is soft and elastic, has low allergenicity, and is more comfortable for the oral mucosa to contact with it, greatly reducing irritation.

[0042] Based on the characteristics of the silicone component, after the cover is inserted into the matching groove 4, it can be firmly buckled in the groove, and covered on the installation end surface 3 through the cover sheet 10, thereby improving the comfort of the patient.

[0043] Embodiment 4:

[0044] In order to facilitate the removal or replacement of the cover, an independent component - nail removal is also included;

[0045] The nail removal device can be used specifically for removing the cover. A straight slit 11 is provided in the center of the cover to penetrate the cover sheet 10 and the plug 9. The nail removal device includes a straight rod 13 that is longer than the thickness of the cover. A T-shaped handle 14 is provided at the top of the straight rod 13 and vertically connected thereto. A nail plate 12 is provided at the bottom of the straight rod 13. The side of the nail plate 12 is provided with a chamfered structure so that the side gradually becomes thinner to facilitate insertion into the slit 11. The width of the nail plate 12 is adapted to the slit 11.

[0046] The specific method of use is to insert the nail plate 12 from the slit 11 to the matching groove 4 below the plug 9, rotate the straight rod 13 90 degrees so that the nail plate 12 no longer corresponds to the slit 11, and preferably in a vertical state, and then lift the handle 14 to bring out the entire cover. When the cover is inserted into the matching groove 4, the plug 9 expands and fits in the matching groove 4, and through biting and daily movements, it will only increase the tightness of the insertion and will not come out by itself. And the straight slit 11 is in a tightly closed state when the plug 9 is inserted, unless the nail plate 12 is inserted downward, no residue or other stolen goods will enter.
