Description

Technical Field

[0001] The utility model relates to the technical field of artificial teeth, in particular to an oral implant repair artificial tooth. Background Art

[0002] Patients with missing teeth in their mouths will have dental implants implanted in the missing tooth area to improve their chewing function. Dental implants, also known as implant dentures, are implants (artificial tooth roots) that are implanted in the alveolar bone in the missing tooth area of ​​the mouth. After the implant takes effect, a restoration is made on its upper end to complete the restoration of the implant denture.

[0003] Common implant dentures now include implants, abutments and crowns. The implant is a cylinder with threads on the outer wall. The implant is installed on the alveolar bone of the patient's mouth where there are missing teeth. The abutment is threadedly connected to the implant, and the crown is set on the abutment.

[0004] Regarding the above technical conditions, there is still a defect that the implant and the base of the implant denture are fixed by a threaded connection, and the base and the implant are prone to loosening, which is not stable enough.

[0005] Based on this, the utility model designs an oral implant restoration denture to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide an oral implant restoration denture to solve the above technical problems.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an oral implant restoration denture, comprising an implant, an abutment and a crown, the crown being arranged on the abutment, the abutment being fixedly connected with a threaded rod, the threaded rod being integrally formed with the abutment, the implant being provided with a fixing hole, the fixing hole being provided with threads, a spring gasket being placed in the fixing hole, the threaded rod being threadedly connected in the fixing hole, the spring gasket being between the fixing hole and the threaded rod, the threaded rod being pressed against the spring gasket, and the spring gasket being pressed against the fixing hole.

[0008] Preferably, the dental crown is fixedly provided with a reinforcement plate.

[0009] Preferably, an adjustment block is fixedly provided at one end of the base away from the dental crown, and the adjustment block is between the base and the threaded rod.

[0010] Preferably, the adjustment block is hexagonal in shape, the base is a cylindrical column, and the adjustment block and the base are in a circumscribed circle relationship.

[0011] To sum up, the present application has the following beneficial technical effects: when installing an implant denture, the implant is installed on the alveolar bone at the patient's edentulous part, the spring washer is placed in the fixing hole of the implant, and the threaded rod is threadedly connected to the fixing hole. When the threaded rod is completely screwed into the fixing hole, the threaded rod presses against the spring washer, and the spring washer is compressed. The spring washer will generate upward and downward reaction forces, so that the two ends of the spring washer press against the fixing hole and the threaded rod respectively. At this time, the threads on the threaded rod will be in closer contact with the threads in the fixing hole, and are not easy to loosen, thereby achieving the effect of making the connection between the abutment and the implant not easy to loosen.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The following is combined with Figure 1-5This application is described in further detail.

[0022] An oral implant restoration denture comprises an implant 3, a base 4 and a crown 1. The outer wall of the implant 3 is provided with a thread. The implant 3 is installed on the toothless part of the patient's mouth. The implant 3 is provided with a fixing hole 8, and the fixing hole 8 is provided with a thread.

[0023] The crown 1 is set on the base 4, and a reinforcing plate 2 is fixedly set on the outer wall of the crown 1. The reinforcing plate 2 is set on the side of the patient's mouth close to the tongue. The reinforcing plate 2 strengthens the force strength of the crown 1, making it difficult for the crown 1 to be damaged by force.

[0024] A threaded rod 6 is fixedly arranged on one side of the base 4 away from the crown 1, and the threaded rod 6 and the base 4 are integrally formed. A spring washer 7 is installed in the fixing hole 8, and the spring washer 7 is installed at the bottom of the fixing hole 8. The threaded hole is threadedly connected to the fixing hole 8, and the spring washer 7 is between the fixing hole 8 and the threaded rod 6. As the threaded rod 6 is continuously tightened downward, the threaded rod 6 presses against the spring washer 7, the spring washer 7 is compressed, and the spring washer 7 presses against the fixing hole 8.

[0025] An adjusting block 5 is fixedly arranged on one side of the base 4 away from the crown 1. The adjusting block 5 is between the base 4 and the threaded rod 6. The adjusting block 5 and the base 4 are integrally formed, and the adjusting block 5 facilitates the threaded rod 6 to be screwed into the fixing hole 8. The adjusting block 5 is hexagonal in shape, and the base 4 is a cylindrical main body. The adjusting block 5 and the base 4 are in a circumscribed circle relationship, so as to prevent the adjusting block 5 from affecting the installation of the crown 1 on the base 4.

[0026] The implementation principle of this embodiment is: when installing the implant denture, the implant 3 is installed on the alveolar bone of the patient's toothless part, the spring gasket 7 is placed in the fixing hole 8 of the implant 3, and the threaded rod 6 is threadedly connected to the fixing hole 8. When the threaded rod 6 is completely screwed into the fixing hole 8, the threaded rod 6 presses against the spring gasket 7, and the spring gasket 7 is compressed. The spring gasket 7 will generate upward and downward reaction forces, so that the two ends of the spring gasket 7 press against the fixing hole 8 and the threaded rod 6 respectively. At this time, the thread on the threaded rod 6 will be in closer contact with the thread in the fixing hole 8, and it is not easy to loosen, so as to achieve the effect of making the connection between the base 4 and the implant 3 not easy to loosen.
