Description

Technical Field

[0001] This utility model relates to the field of implant technology, specifically a lateral fixation implant. Background Technology

[0002] Implant-supported dentures are currently the best option for restoring missing teeth. However, when a patient has insufficient maxillary bone, it may be impossible to implant an implant at the site of the missing tooth, or even if an implant is implanted, its length may be insufficient, leading to instability and inability to properly support the superstructure. Another method is to anchor the implant into the bone outside the alveolar bone, such as transapical, transzygomatic, or transnasal implants. While these methods can achieve the required implant stability, they are more complex to perform and can easily damage surrounding tissues. For example, in transnasal implants, part of the implant enters the nasal cavity, affecting normal nasal function and potentially damaging the soft tissues within the nasal cavity. Utility Model Content

[0003] The purpose of this invention is to provide a lateral fixation implant to solve the problem in the prior art that when patients have insufficient maxillary bone, it is impossible to implant an implant in the edentulous area, or even if an implant is implanted, its length is insufficient, resulting in insufficient stability of the implant and inability to support the superstructure.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a lateral fixation implant, comprising an implant body, a fixing cavity provided at the top of the implant body, a fixing needle provided in the fixing cavity, the fixing cavity comprising a conical shape, an anti-rotation structure, a threaded hole, a first hole, a second hole and a third hole arranged sequentially from top to bottom, the outer surface of the implant body being provided with a first thread, and the outer wall of the implant body located on the first thread being formed with a fourth hole, the fourth hole being arranged in communication with the third hole, the fixing needle comprising a cap, a rod, an anti-retraction thorn and a tip arranged sequentially from top to bottom, the anti-rotation structure having a hexagonal cavity in its horizontal cross section.

[0005] Preferably, the top of the cap is formed with a second thread.

[0006] Preferably, the fixing pin is made of a highly elastic material.

[0007] Preferably, the cap head fits into the first hole cavity, and the lateral width of the cap head is greater than the diameter of the second hole, while the diameter of the second hole is smaller than the diameter of the first hole.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] 1. This application effectively enhances the stability of the implant through the double fixation of the lateral fixation pin, avoiding the shortcomings of insufficient implant retention and complex transapical and zygomatic implantation methods. Furthermore, the lateral fixation implant can be used when there is insufficient alveolar bone volume in the maxilla.

[0010] 2. This application uses 3D printing to process the internal curved holes, and then uses conventional machining methods to complete the conventional machining, which greatly reduces the processing difficulty. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figure 1 - Figure 7 As shown, this utility model provides a technical solution for lateral fixation of an implant, including an implant body 1, a fixing cavity at the top of the implant body 1, a fixing needle 2 in the fixing cavity, the fixing cavity including a conical shape 12, an anti-rotation structure 13, a threaded hole 14, a first hole 15, a second hole 16 and a third hole 18 arranged sequentially from top to bottom, the outer surface of the implant body 1 is provided with a first thread 11, and the outer wall of the implant body 1 located on the first thread 11 is formed with a fourth hole 17, the fourth hole 17 and the third hole 18 are arranged in a through manner, the fixing needle 2 including a cap 21, a rod 22, an anti-retraction spur 23 and a tip 24 arranged sequentially from top to bottom;

[0021] Currently, machining cannot produce curved holes like the third hole 18, so 3D printing is used.

[0022] The implant body 1 is manufactured entirely using 3D printing. The manufacturing method is as follows: First, a cylindrical blank is manufactured using 3D printing. The cylindrical blank contains the second hole 16, the third hole 18, and the fourth hole 17 of the implant body 1. Then, conventional machining methods are used to process the cylinder into... Figure 2 The implant body 1 is shown;

[0023] The anti-retraction spike 23 prevents the retaining pin 2 from being accidentally withdrawn. The tip 24 facilitates the anchoring of the retaining pin 2. The second thread 25 facilitates the removal of the threaded rod and other components, thus making it easier to pull out the retaining pin 2.

[0024] like Figure 6 As shown, the top of the cap 21 is formed with a second thread 25.

[0025] like Figure 1 As shown, the fixing pin 2 is made of a highly elastic material;

[0026] The material of the fixing pin 2 can be nickel-titanium alloy, pure titanium, titanium alloy, etc.

[0027] like Figure 2 , Figure 3 and Figure 5 As shown, the cap 21 is cavity-fitted with the first hole 15, and the lateral width of the cap 21 is greater than the diameter of the second hole 16, while the diameter of the second hole 16 is smaller than the diameter of the first hole 15.

[0028] Instructions for use: First, screw the implant body 1 into the alveolar bone, making sure to adjust the fourth hole 17 to the direction of the lateral bone where the fixation pin 2 is expected to anchor. Then, insert the fixation pin 2 into the fixation cavity of the implant body 1 and tap it until it is anchored into the lateral bone. If you need to remove the fixation pin 2, you can use a threaded rod to screw into the second thread 25 and pull out the fixation pin 2. The conical shape 12, the anti-rotation structure 13, and the threaded hole 14 are used to connect with the superstructure abutment.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
