Description

Technical Field

[0001] This utility model relates to an implant used in dental implant treatment, specifically to a base bone implant structure applied to dental implant treatment for alveolar bone atrophy. Background Technology

[0002] Note: Dental implantation is a treatment that replaces tooth roots with artificial ones to fill missing teeth. The implantation process begins by inserting an artificial metal implant into the alveolar bone as a stable foundation. After the bone grows and covers the artificial implant, and the implant is confirmed to be well integrated with the bone (i.e., osseointegration), a support frame is attached, and then a crown is added, completing the implantation procedure. However, for patients with alveolar bone atrophy, implants cannot be placed in the atrophied alveolar bone. Bone reconstruction treatment must be performed simultaneously on the atrophied alveolar bone to ensure the implant threads are completely covered within the bone tissue, thus ensuring a healthy and durable implant.

[0003] Please refer to the above steps of the dental implant treatment. Figure 6 , 7 As shown, in cases of tooth loss due to alveolar bone atrophy, the gingiva 30 must be incised to expose the alveolar bone 31. An implantation hole is then made in the alveolar bone 31 to allow for the insertion of an implant 40. Traditionally, the implant 40 has only a threaded section 41 on its outer periphery, which is then locked into the implantation hole in the alveolar bone 31. Due to alveolar bone atrophy, the threaded section may extend beyond the implantation hole. Therefore, bone powder 32 needs to be added between the gingiva 30 and the alveolar bone 31 to repair the lost bone in the alveolar bone 31. The gingiva 30 is then sutured to allow the bone powder 32 to induce the alveolar bone 31 to regenerate and form a supplementary tooth. The alveolar bone 311 is used to encapsulate the implant 40, thereby improving the stability of the implant 40 and the alveolar bone 20. However, this method of bone reconstruction using alveolar bone 311 usually requires several bone grafts. Not only is the surgical procedure complicated and the operation time long, but the bone grafts 32 are also inevitably subject to self-absorption after filling, which can cause the threaded segment 41 of the implant 40 to be exposed and come into contact with the soft tissue of the gingiva 30, resulting in inflammation. In severe cases, it can even cause inflammation and suppuration of the gingiva 30 tissue around the implant 40, leading to implant treatment failure.

[0004] In view of this, based on the author's many years of experience in manufacturing, developing and designing related products, and after detailed design and careful evaluation for the above objectives, the author has finally come up with this utility model that is indeed practical. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a basal bone implant structure to address the above-mentioned deficiencies in the existing technology. The implant includes an implant with a threaded section and a smooth section on its outer surface. The diameter of the smooth section is smaller than that of the threaded section, and the length of the smooth section is between 2mm and 7mm. A micro-threaded section is provided on the surface of the smooth section at least 1mm from the top. The width of the micro-threaded section is between 1mm and 2mm. The surface of the smooth section is treated with an anodized coating.

[0006] Preferably, a joint platform is formed at the top of the smooth surface segment, and an internal hexagonal hole is provided inward from the joint platform. An expanding hole is formed upward from the end edge of the internal hexagonal hole. The expanding hole has an outward expansion angle of 11 degrees with the internal hexagonal hole as a reference. A first internal thread segment and a second internal thread segment are provided inward from the internal hexagonal hole. The diameter of the second internal thread segment is smaller than that of the first internal thread segment.

[0007] Preferably, the micro-threaded section is a threaded surface with a pitch width of 70 μm and a thread depth of 20 μm.

[0008] Preferably, a fine thread segment is provided between the threaded segment and the smooth surface segment. The diameter of the fine thread segment is smaller than the diameter of the threaded segment but larger than the diameter of the smooth surface segment, and the width of the fine thread segment is at least 1 mm.

[0009] Preferably, the distance between the fine thread segment and the micro-thread segment is greater than the distance between the micro-thread segment and the engagement platform.

[0010] Preferably, the distance between the fine thread segment and the micro-thread segment is less than the distance between the micro-thread segment and the engagement platform.

[0011] Preferably, the axis of the threaded segment forms a tapered core with a gradually decreasing diameter from top to bottom, and the threaded segment forms a progressive thread that gradually thins and deepens from the tapered core to the root, and a rounded end arc is smoothly designed at the tip of the threaded segment.

[0012] Compared to the effectiveness of previous technologies: The implant of this invention is mainly implanted deep into the basal bone. The threaded segment can be completely implanted into the basal bone and the alveolar bone, while the smooth segment extends out of the alveolar bone to allow for gingival healing and coverage. It is especially suitable for patients with atrophied alveolar bone, eliminating the need for bone grafting for alveolar bone reconstruction, reducing complex bone and tissue grafting procedures, shortening the duration of implant pain, and avoiding contact between bone grafting and the threaded segment and gingival soft tissue during the repair process. This avoids the rough surface of the threaded segment causing inflammation of the soft tissue, significantly improving the implantation success rate and contributing to the health of the gingival tissue.

[0013] Furthermore, the smooth surface segment is treated with an anodized coating, which can effectively reduce plaque buildup and benefit gum health. If inflammation still occurs around the implant, causing gingivitis, the smooth surface segment is easy to treat. In addition, the micro-threaded design of the smooth surface segment promotes tight adhesion of the soft tissue of the gums around the implant, preventing bacteria from invading and causing inflammation of the soft tissue around the implant, thereby improving the health and durability of the soft and hard tissues after the dental implant procedure.

[0022] To further understand and recognize the purpose, features, and effects of this utility model, the following is a detailed description in conjunction with the accompanying drawings: First, please let Figure 1 , 2 As shown, a basal bone implant structure includes an implant 10. The outer surface of the implant 10 has a threaded section 11 and a smooth section 12. The threaded section 11 is roughened by sandblasting and acid etching, and the length of the threaded section 11 is between 7 mm and 9 mm. The diameter of the smooth section 12 is smaller than the diameter of the threaded section 11, and the length of the smooth section 12 is between 2 mm and 7 mm. A micro-threaded section 121 is provided on the surface of the smooth section 12 at least 1 mm from the top. The width of the micro-threaded section 121 is between 1 mm and 2 mm, and the micro-threaded section 121 has a threaded surface with a tooth pitch width of 70 μm and a tooth depth of 20 μm. The surface of the smooth section 12 is treated with an anodized coating to have an anodized coating 122.

[0023] Further explanation of its structural embodiments will follow. Figure 1 , 2 As shown in Figure 4, the axis of the threaded segment 11 forms a tapered core 111 with a gradually decreasing diameter from top to bottom. The threaded segment 11 forms a progressively thinning and deepening thread along the tapered core 111 towards its root. A rounded end arc 112 is smoothly designed at the tip of the threaded segment. A fine threaded segment 13 is provided between the threaded segment 11 and the smooth surface segment 12. The diameter of the fine threaded segment 13 is smaller than the diameter of the threaded segment 11 but larger than the diameter of the smooth surface segment 12. The fine threaded segment 13 is also roughened by sandblasting and acid etching. A mating platform 123 is formed at the top of the smooth surface segment 12. An internal hexagonal hole 14 is provided inward from the mating platform 123. A gradually expanding hole 141 (Morse) is formed upward from the upper edge of the internal hexagonal hole 14. The tapered hole 141 is connected to the internal hexagonal socket 14 and has an outward expansion angle of 11 degrees based on the internal hexagonal socket 14. The internal hexagonal socket 14 has a first internal thread segment 142 and a second internal thread segment 143, the diameter of which is smaller than that of the first internal thread segment 142. For implants with a diameter of 4.5-5.0 mm or more, only the first internal thread segment 142 is present, and its diameter is 2.0 mm.

[0024] Then by Figure 3 As shown in Figure 3-1, the smooth surface segment 12 of the implant 10 has a total length of 2 mm, and a micro-threaded segment 121 with a width of 1 mm is provided 1 mm below the top of the smooth surface segment 12. The distance between the fine threaded segment 13 and the micro-threaded segment 121 is less than the distance between the micro-threaded segment 121 and the joint platform 123. As shown in Figure 3-2, the smooth surface segment 12 of the implant 10 has a total length of 3 mm, and a micro-threaded segment 121 with a width of 1.5 mm is provided 1 mm below the top of the smooth surface segment 12. The distance between the fine threaded segment 13 and the micro-threaded segment 121 is less than the distance between the micro-threaded segment 121 and the joint platform 123. As shown in 3-3, the total length of the smooth surface segment 12 of the implant 10 is 5mm, and a 2mm wide micro-threaded segment 121 is provided 1mm below the top of the smooth surface segment 12. The distance between the fine threaded segment 13 and the micro-threaded segment 121 is greater than the distance between the micro-threaded segment 121 and the joint platform 123. As shown in 3-4, the total length of the smooth surface segment 12 of the implant 10 is 7mm, and a 2mm wide micro-threaded segment 121 is provided 1mm below the top of the smooth surface segment 12. The distance between the fine threaded segment 13 and the micro-threaded segment 121 is greater than the distance between the micro-threaded segment 121 and the joint platform 123. The above dimensions are only embodiments of the implant 10 in this case and are not limited thereto.

[0025] Its actual structural state in use, please refer to [the following text is incomplete and requires further context]. Figure 5 As shown, the implant 10 is designed to be implanted in the base bone 20 of the denser and less resorbable jawbone, rather than in the more resorbable or softer alveolar bone 21, especially in patients whose alveolar bone 21 has severely atrophied, such as... Figure 5The right alveolar bone 21 has atrophied and fallen below the left alveolar bone 21, so alveolar bone reconstruction is not required for dental implant surgery. The implant 10 features a self-tapping threaded section 11, allowing for direct insertion and reducing surgical steps. The progressive design and oblique grooves of the threaded section 11 concentrate bone fragments during insertion, facilitating integration between the basal bone 20 and the threaded section 11. Finally, a tapered conical core 111 ensures stable insertion of the threaded section 11, facilitating the implant 10's insertion into the patient's basal bone 20 and ensuring complete implantation of the threaded section 11. Furthermore, the root end arc 112 of the threaded section 11 effectively reduces the risk of nerve damage. There are concerns about dangerous anatomical structures such as blood vessels. Furthermore, when the threaded segment 11 is inserted into the base bone 20, the fine threaded segment 13 is screwed onto the atrophied alveolar bone 21, ensuring that the threaded segment 11, whose surface is roughened by sandblasting and acid etching, does not expose itself in contact with the gingiva 22. This avoids contact between the threaded segment 11 and the gingiva 22, as the rough threads can cause inflammation of the soft tissue. It also prevents food and debris from adhering to the threaded segment 11. The implant 10 only extends the smooth segment 12 outside the alveolar bone 21 for the gingiva 22 to cover it. The micro-threaded segments 121 of the smooth segment 12 help ensure tight adhesion of the soft tissue of the gingiva 22 surrounding the implant 10, improving the seal between the gingiva 22 and the implant 10, thereby preventing bacterial invasion. Alternatively, if aesthetic factors are considered, bone and tissue grafting can be performed on the smooth segment 12.

[0026] After the implantation of the implant 10 is completed, a support 15 can be installed on the joint platform 123 of the smooth surface segment 12 so that the gingiva 22 can grow along the periphery of the support 15 during healing, further filling the gap between the joint platform 123 and the gingiva 22. After the gingiva 22 heals, the denture 16 can be installed to complete the dental implantation treatment.

[0027] Through the structure of the above specific embodiments, the following benefits can be obtained: The implant 10 of this utility model is mainly implanted deep into the basal bone. The threaded segment 11 can be completely implanted into the basal bone 20 and the alveolar bone 21, and the smooth surface segment 12 extends out of the alveolar bone 21 for the gingiva 22 to heal and cover it. It is especially suitable for patients whose alveolar bone 21 has atrophied. There is no need to supplement bone powder for the reconstruction of alveolar bone 21, reducing the complex bone and flesh filling surgical procedures, reducing the pain time of dental implantation, and avoiding inflammation caused by contact between bone powder and the threaded segment 11 and the soft tissue of the gingiva 22 during the bone powder repair process. This greatly improves the implantation success rate of the implant 10 and helps the health of the gingival tissue.

[0028] Furthermore, the smooth surface segment 12 is treated with an anodized coating 122, which can effectively reduce plaque adhesion and benefit gum health. If inflammation still occurs around the implant 10, causing gingivitis, the smooth surface segment 12 is also easy to treat. In addition, the micro-threaded segment 121 of the smooth surface segment 12 promotes the tight attachment of the soft tissue of the gingiva 22 around the implant 10, preventing bacteria from invading and causing inflammation of the soft tissue around the implant, thereby improving the health and durability of the soft and hard tissues after the dental implant treatment.

[0029] The above description is only a preferred embodiment of this utility model and should not be construed as limiting the scope of this utility model; that is, all equivalent changes and modifications made in accordance with the scope of the patent application of this utility model should still fall within the scope of this utility model patent.
