Description

Technical Field

[0001] The utility model relates to the technical field of dental implants, in particular to an oral implant component. Background Art

[0002] A dental implant refers to a tooth defect restoration method that uses the lower structure implanted in bone tissue to support and retain the upper dental restoration; it includes two parts: the lower support implant and the upper dental restoration; it uses artificial materials to make the implant, which is implanted into the tissue through a surgical method and obtains firm retention and support from bone tissue, and is connected to support the upper dental restoration through special devices and methods; dental implants can obtain a restoration effect very similar to that of natural teeth in terms of function, structure, and aesthetic effect, and have become the preferred restoration method for more and more toothless patients.

[0003] Due to the small gap between teeth, when implanting teeth, the artificial dental crown usually can only be fixed by bolts through a slot at the top, and the slot at the top of the artificial dental crown is filled with resin. Since the resin is relatively fragile compared to the artificial dental crown and is at the contact point of the teeth, the pressure is relatively large, which affects the service life of the dental implant. Moreover, after the resin is filled, it affects the alveolar shape at the top of the artificial dental crown, resulting in an impact on the speed of subsequent teeth grinding food. Therefore, an oral implant component is proposed to solve the above problems. Summary of the Utility Model

[0004] The utility model provides an oral implant component, which solves the above technical problems.

[0005] To solve the above technical problems, an oral implant component provided by the utility model includes a connecting body, a implant is fixed at the upper end of the connecting body, a connecting column is rotationally connected to the inner surface of the implant through threads, a lower connecting box is fixed at the upper end of the connecting column, an upper connecting box is rotationally connected to the upper end of the lower connecting box, a positioning block is fixed on the surface of the upper connecting box, a limiting plate is rotationally connected to the lower end of the positioning block, a helical gear is fixed on the inner surface of the lower connecting box, and the limiting plate is unidirectionally clamped with the helical gear. An artificial dental crown is connected to the upper end of the upper connecting box.

[0006] Preferably, a locking block is fixed on the surface of the lower connecting box, and a spring is fixed on the surface of the locking block.

[0007] Preferably, the other end of the spring relative to the locking block is fixedly connected to the limiting plate.

[0008] Preferably, a base post is arranged between the upper connecting box and the artificial dental crown, and a slot is arranged on the surface of the artificial dental crown, and the base post is clamped with the slot.

[0009] Preferably, a tooth groove is arranged at the upper end of the artificial dental crown, and the tooth groove is recessed lowest at the middle position of the artificial dental crown.

[0010] Preferably, the helical teeth are inclined teeth, and the limiting plate is inclined relative to the helical teeth.

[0011] Compared with the related art, an oral implant component provided by the present utility model has the following beneficial effects:

[0012] With the ratchet structure of the present utility model, the artificial dental crown can drive the connecting column to continuously rotate in one direction when rotating back and forth within a small range, thus facilitating the installation of the artificial dental crown, avoiding the reduction of the service life caused by fixing the top of the artificial dental crown with resin. At the same time, the shape of the top of the original artificial dental crown is better, which speeds up the grinding speed of food. By applying resin at the joint of the lower connection box and the upper connection box, it can ensure that the artificial dental crown will not shake after installation, ensuring the normal use of the teeth.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] An embodiment is given by Figure 1-6 The present utility model includes an oral implant component, which includes a connector 3. The upper end of the connector 3 is fixed with an implant 2. The inner surface of the implant 2 is rotationally connected with a connecting column 5 through a thread. The upper end of the connecting column 5 is fixed with a lower connection box 6. The upper end of the lower connection box 6 is rotationally connected with an upper connection box 7. The surface of the upper connection box 7 is fixed with a positioning block 11. The lower end of the positioning block 11 is rotationally connected with a limiting plate 8. The inner surface of the lower connection box 6 is fixed with helical teeth 12. The limiting plate 8 is unidirectionally engaged with the helical teeth 12. The upper end of the upper connection box 7 is connected with an artificial dental crown 1.

[0021] A locking block 10 is fixed on the surface of the lower connecting box 6, and a spring 9 is fixed on the surface of the locking block 10.

[0022] The other end of the spring 9 relative to the locking block 10 is fixedly connected to the limiting plate 8.

[0023] A dental implant 4 is arranged between the upper connecting box 7 and the artificial dental crown 1, and a slot is arranged on the surface of the artificial dental crown 1, and the dental implant 4 is clamped with the slot.

[0024] A tooth groove is arranged at the upper end of the artificial dental crown 1, and the tooth groove is recessed lowest at the middle position of the artificial dental crown 1.

[0025] The helical tooth 12 is an inclined tooth, and the limiting plate 8 is arranged obliquely relative to the helical tooth 12.

[0026] Install the implant 2 into the surface of the alveolar bone, align the connecting column 5 with the implant 2, and rotate the artificial dental crown 1 so that the connecting column 5 is connected to the implant 2. When the gap between adjacent teeth is small and the artificial dental crown 1 cannot be rotated widely, rotate the artificial dental crown 1. The artificial dental crown 1 drives the upper connecting box 7 to rotate through the dental implant 4, the upper connecting box 7 drives the limiting plate 8 to rotate through the positioning block 11, and the limiting plate 8 pushes the helical tooth 12, thereby driving the lower connecting box 6 to rotate, then the connecting column 5 is connected to the implant 2. Rotate the artificial dental crown 1 in the reverse direction. Since the limiting plate 8 and the helical tooth 12 are unidirectionally clamped, the spring 9 deforms during reverse rotation, the limiting plate 8 moves relative to the helical tooth 12, and the artificial dental crown 1 returns to the position before rotation, thereby driving the connecting column 5 to rotate again.
