Technical Field

[0001] The utility model relates to the field of implants, in particular to a stable implant with double thread grooves. Background Art

[0002] Tooth loss is a common and frequently occurring disease in humans. As a revolutionary advancement in tooth loss repair, dental implant technology has completely changed the concept and model of traditional oral restoration and has achieved good clinical treatment results. Dental implants used in dental implants are usually placed in the jawbone to replace extracted or fallen teeth, so that dentures or crowns that function as dentures can be maintained there after a healing period of 3 to 4 months.

[0003] In the prior art, due to the limited contact area between the implant and the inner wall of the socket bone, the initial combination of the implant and the maxillary and mandibular tissues is unstable, which may cause the implant to loosen and fall off after long-term use, leading to implant failure. Utility Model Content

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the problem of low long-term stability caused by insufficient bonding between the device body and the alveolar bone in the prior art, thereby providing a stable implant with double thread grooves.

[0005] In order to solve the above technical problems, the utility model provides a stable implant with double thread grooves, comprising:

[0006] An implant structure, comprising: an implant body, a cutting edge arranged at one end of the implant body, and an implant hole opened at the other end of the implant body;

[0007] The thread structure includes: an external thread opened on the outer wall of the implant body, a first thread groove formed by adjacent external threads and the implant body, and a second thread groove opened on the bottom surface of the first thread groove, wherein the second thread groove has the same spiral direction as the first thread groove, and a transition surface is provided between the second thread groove and the external thread.

[0008] In an embodiment of the present invention, the implant body is further provided with attachment holes, and the attachment holes are arranged along the radial direction of the implant body.

[0009] In one embodiment of the present invention, the attachment hole is opened in the second thread groove along the radial direction of the implant, and the size of the attachment hole is not greater than the width of the second thread groove.

[0010] In one embodiment of the present invention, the spacings between adjacent attachment holes are the same, and the number of the attachment holes gradually decreases from the crown assembly end to the cutting end.

[0011] In one embodiment of the present invention, the second thread groove is provided between adjacent external threads, and the spacing between the second thread groove and the external thread is not less than 0.12 mm, and the transition surface is a rounded transition surface, and the radius of the rounded corner is not less than 0.1 mm.

[0012] In one embodiment of the present invention, the second thread groove is semicircular, and the radius of the second thread groove is not less than 0.1 mm.

[0013] In one embodiment of the present invention, the slopes of the walls on both sides of the first thread groove are different, and the slope of the wall at one end of the first thread groove close to the cutting edge is greater than that at the other end.

[0014] In one embodiment of the present invention, the implant body is a conical structure, and the taper of the implant body is 10 degrees to 15 degrees.

[0015] In an embodiment of the present invention, the external thread is any one of a trapezoidal thread and a triangular thread.

[0016] In an embodiment of the present invention, the curvature of the transition surface is consistent with the curvature of the second thread groove.

[0017] The above technical solution of the utility model has the following advantages compared with the prior art:

The double thread groove structure increases the bone integration speed, and the design of the transition surface enables the implant to disperse stress more evenly when subjected to force, thereby reducing the risk of implant damage. The presence of the second thread groove enables bone cells to grow into the implant surface faster. After the implant is implanted, bone tissue begins to grow into the thread groove on the implant surface to form a biological bond. As the bone integration is gradually completed, a solid bond is formed between the implant and the alveolar bone, thereby realizing long-term stability, shortening the postoperative recovery time and improving the long-term success rate of the implant.

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0025] Example

[0026] Reference Figure 1-Figure 3 As shown, the utility model is a stable implant with double thread grooves, comprising:

[0027] The implant structure comprises: an implant body 1, a cutting edge 4 arranged at one end of the implant body 1, and an implant hole 6 opened at the other end of the implant body 1;

[0028] The thread structure includes: an external thread 2 opened on the outer wall of the implant body 1, a first thread groove 3 formed by adjacent external threads 2 and the implant body 1, and a second thread groove 7 opened on the bottom surface of the first thread groove 3, wherein the second thread groove 7 has the same spiral direction as the first thread groove 3, and a transition surface 8 is provided between the second thread groove 7 and the external thread 2.

[0029] The utility model discloses a stable implant with double thread grooves, wherein the implant hole 6 is used to install a crown denture, and the cutting edge 4 of the implant body 1 makes the implantation process more efficient and minimally invasive. The cutting edge 4 can accurately and quickly penetrate the bone tissue, reducing the operation time and the patient's discomfort, while reducing the damage to the surrounding tissue during the operation, and reducing the risk of postoperative complications. The double thread grooves are provided to enhance the ability of the implant to combine with the surrounding bone tissue. The cooperation of the first thread groove 3 and the second thread groove 7 not only provides a larger contact area, but also realizes a more solid mechanical locking through the interlocking action of the double thread, so that the implant can remain stable when subjected to physiological loads such as chewing force, effectively reducing the risk of loosening or falling off. The double thread groove structure is used to increase the bone integration speed. The design of the transition surface 8 enables the implant to disperse stress more evenly when subjected to force, reducing the risk of implant damage. Due to the presence of the second thread groove 7, bone cells can grow into the implant surface faster. After the implant is implanted, the bone tissue begins to grow into the thread groove on the implant surface to form a biological bond. As time goes by, bone integration is gradually completed, and a strong bond is formed between the implant and the alveolar bone, thus achieving long-term stability and functionality, thereby accelerating the biological integration process between the bone and the implant, shortening the postoperative recovery time and improving the long-term success rate of the implant.

[0030] See also Figure 3 As shown, the implant body 1 is also provided with an attachment hole 5, which is arranged along the radial direction of the implant body 1. The arrangement of the attachment hole 5 enables the implant to better combine with the surrounding bone tissue after implantation. At the second thread groove 7, the attachment hole 5 provides additional growth space for bone cells. The presence of the attachment hole 5 also helps to improve the retention force of the implant. When the bone tissue grows into the attachment hole 5, it will form a closer combination with the implant, thereby increasing the resistance of the implant when subjected to force. During the postoperative recovery period, the bone cells gradually fill the attachment hole 5 and the thread groove to form a biological combination with the implant. This combination is strengthened over time, and eventually the implant and the alveolar bone are integrated to achieve long-term stable retention. In this process, the design of the double thread groove also plays an important role. It enhances the bonding strength and stability of the implant and the alveolar bone through spiral arrangement. The attachment holes 5 are also spirally arranged at the second thread groove 7, so that the bonding force is evenly distributed.

[0031] See also Figure 2 , Figure 3As shown, the attachment hole 5 is opened in the second thread groove 7 along the radial direction of the implant, and the size of the attachment hole 5 is not greater than the width of the second thread groove 7. Since the position of the attachment hole 5 corresponds to the second thread groove 7, bone cells can grow along the direction of the thread groove, further enhancing the bonding force between the implant and the bone tissue. The size of the attachment hole 5 is not greater than the width of the second thread groove 7, ensuring the structural stability and torsion resistance of the implant. The size of the attachment hole 5 matches that of the second thread groove 7, so that the implant can evenly distribute stress when subjected to force, reducing the risk of deformation and damage to the implant.

[0032] See also Figure 1 As shown, the spacing between adjacent attachment holes 5 is the same, and the number of attachment holes 5 gradually decreases from the crown assembly end to the cutting end. At the crown assembly end, that is, the upper part of the implant, more attachment holes 5 help to increase the contact area with the bone, thereby enhancing the initial stability of the implant after implantation. The design of gradually reducing attachment holes 5 helps to optimize stress distribution, avoid excessive stress concentration in a certain area, and reduce the risk of implant damage caused by stress concentration. A reasonably designed number of attachment holes can reduce the use of materials and processing difficulty while ensuring performance, thereby reducing costs. According to different clinical conditions and patient needs, the number and distribution of attachment holes can also be adjusted to adapt to different implantation conditions.

[0033] See also Figure 3 As shown, the second thread groove 7 is opened between adjacent external threads 2, and the spacing between the second thread groove 7 and the external thread 2 is not less than 0.12mm, which is 0.12mm in the present embodiment, and can also be 0.15mm. The transition surface 8 is a rounded transition surface 8, and the radius of the fillet is not less than 0.1mm, which is 0.1mm in the present embodiment, and can also be 0.12mm, 0.15mm, and a spacing above 0.12mm ensures that there is enough space between the second thread groove 7 and the external thread 2 to accommodate bone cells and bone tissue, thereby increasing the stability and compression resistance of the implant. The design of the rounded transition surface 8 reduces the possibility of bacterial growth at sharp edges, as well as the situation where the small connecting cross-sectional area at the hyperplasia leads to lack of supply and thus necrosis, thereby reducing the risk of infection. The design of the rounded transition surface 8 reduces the friction and stimulation between the implant and the surrounding soft tissue, improves the patient's comfort, reduces postoperative discomfort, and is beneficial to the healing and success rate of the implant.

[0034] Continue to see Figure 3 As shown, the second thread groove 7 is semicircular, and the radius of the second thread groove 7 is not less than 0.1 mm, which reduces the friction and stimulation between the implant and the surrounding soft tissue, improves the patient's comfort, and reduces postoperative discomfort. The diameter of the second thread groove 7 is not greater than the distance between adjacent external threads 2.

[0035] The inclinations of the walls on both sides of the first thread groove 3 are different, and the inclination of the wall at one end of the first thread groove 3 near the cutting edge 4 is greater than that at the other end, making it easier for the implant to penetrate bone tissue and improving the implantation effect. The design of the larger inclination of the wall at one end near the cutting edge 4 helps the implant to cut into the bone tissue more smoothly, reducing the operation time and patient discomfort, and improving the tensile strength of the implant. The doctor uses special tools to implant the implant into the patient's jawbone. By setting the first thread grooves with different inclinations, the larger inclination of the wall at one end near the cutting edge can more easily penetrate the bone tissue, ensuring the correct implantation position and stability of the implant, making the implantation operation more precise and effective, and improving the implantation effect and success rate.

[0036] See also Figure 1 As shown, the implant body 1 is a conical structure, and the taper of the implant body 1 is 10 degrees to 15 degrees, and is 13 degrees in the present embodiment. In the alveolar bone with a hole opened, the conical structure of the implant body 1 is designed to help gradually expand the implantation channel during the implantation process and abut against the inner wall of the alveolar bone.

[0037] See also Figure 1 , Figure 2 As shown, the external thread 2 is any one of a trapezoidal thread or a triangular thread, and the curvature of the transition surface 8 is consistent with the curvature of the second thread groove 7, which can reduce the difficulty of processing and reduce the cost of use. The design of the trapezoidal thread or the triangular thread can reduce the space for bacterial growth and reduce the risk of infection, which is beneficial to improving the healing and success rate of the implant.

[0038] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
