Description

[Technical Field]

[0001] The present invention relates to an implant body used in dental implant surgery, and more particularly to the structure of an implant body to be implanted into basal bone used in dental implant surgery for alveolar bone atrophy. [Background technology]

[0002] Generally, dental implants are a procedure that replaces tooth roots with artificial root implants to compensate for missing teeth. The procedure involves first implanting an artificial metal root implant into the alveolar bone, which acts as a strong foundation for bone growth to cover the artificial root implant. After confirming whether the root implant is firmly integrated with the bone (known as "osseointegration"), a pillar kit is attached to the apex, and then a crown is attached to complete the dental implant procedure. However, for patients with atrophy of the alveolar bone, implants cannot be implanted into the atrophied alveolar bone. In this case, bone reconstruction surgery is required to completely cover the atrophied alveolar bone, and the implant can only be maintained in a healthy state for a long time after the threads of the implant are completely covered by the bone tissue.

[0003] Regarding the flow of the dental implant surgery, as shown in Figures 6 and 7, the alveolar bone has atrophy, and the gums 30 are incised from the location of the missing tooth to expose the alveolar bone 31. An implant hole is then drilled downward from the alveolar bone 31, and the implant body 40 is implanted. In the conventional implant body 40, only a threaded portion 41 is provided on the outer periphery, and the threaded portion 41 is screwed into the implant hole of the alveolar bone 31. However, the alveolar bone 31 is not fully formed. Since the implant body 40 shrinks and the screw portion exceeds the implant hole, bone powder 32 must be further filled between the gums 30 and the alveolar bone 31 to add the bone lost from the alveolar bone 31, and the gums 30 are sutured so that the bone powder 32 causes the regeneration of the alveolar bone 31, and the filled alveolar bone 311 is regenerated and formed, and the filled alveolar bone 311 covers the implant body 40, improving the stability between the implant body 40 and the alveolar bone 31. However, this method of reconstructing and increasing bone using alveolar bone 31 requires repeated addition of bone powder, which not only makes the surgical process complicated and time-consuming, but also inevitably leads to self-absorption after the addition of bone powder 32, exposing the thread portion 41 of the implant body 40, which comes into contact with the soft tissue of the gums 30, causing inflammation. In severe cases, this can even cause pus 33, which is inflammation of the gums 30 around the implant body 40, leading to the failure of the implant surgery.

[0004] In view of this, the inventor of the present invention has developed a practical invention after detailed design and precise evaluation based on his many years of experience in the manufacture, development, and design of products in this field, in order to achieve the above goals. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to solve the above-mentioned drawbacks of the prior art and provide an implant structure to be implanted into a base bone, the implant structure including an implant body, the outer surface of the implant body having a threaded portion and a smooth surface portion, the diameter of the smooth surface portion being smaller than the diameter of the threaded portion, the length of the smooth surface portion being between 2mm and 7mm, the surface of the smooth surface portion being provided with a micro-thread portion at least 1mm away from the apex, the width of the micro-thread portion being between 1mm and 2mm, and the surface of the smooth surface portion being anodized by anodizing.

[0006] Preferably, a connecting platform is formed at the top end of the smooth surface portion, the connecting platform has a hexagonal hole formed therein along the inside thereof, a tapered hole formed upward at the edge of the hexagonal hole, the tapered hole having an outward expansion inclination angle of 11 degrees with respect to the hexagonal hole, and the hexagonal hole has a first female thread portion and a second female thread portion formed therein along the inside thereof, the diameter of the second female thread portion being smaller than the diameter of the first female thread portion.

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

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

[0009] Preferably, the distance between the fine thread portion and the fine thread portion is greater than the distance between the fine thread portion and the connection platform.

[0010] Preferably, the distance between the fine thread portion and the fine thread portion is less than the distance between the fine thread portion and the connection platform.

[0011] Preferably, the diameter of the axial portion of the threaded portion gradually decreases from top to bottom to form a conical axis, and the threaded portion forms a progressive thread that thins and deepens toward the end along the conical axis, and the tip of the threaded portion is smoothly designed with a terminal arc portion.

[0012] Comparing the effects of the prior art: The implant body of the present invention is mainly implanted deep into the basal bone, and the threaded portion can be completely implanted into the basal bone and the alveolar bone, and the smooth surface portion extends outward from the alveolar bone to adhere to and cover the gums. This is particularly applicable to patients with alveolar bone atrophy, and does not require bone powder to be inserted and undergo alveolar bone reconstruction surgery. This reduces the need for complicated bone and flesh insertion surgery and shortens the painful period during implantation. At the same time, the threaded portion can be prevented from coming into contact with the soft tissue of the gums when the bone powder is repaired, and the rough surface of the threaded portion can be prevented from causing inflammation in the soft tissue. This greatly improves the implant surgery success rate of the implant body and contributes to the health of the gum tissue.

[0013] Furthermore, the smooth surface portion is provided with the anodized coating through an anodized coating process, which can effectively reduce the adhesion of plaque and is beneficial to gum health. If the area around the implant body is suddenly inflamed and causes gingivitis, the smooth surface portion is also easy to treat. Furthermore, the design of the micro-thread portion of the smooth surface portion promotes tight adhesion of the gum soft tissue around the implant body, prevents bacterial invasion, and prevents inflammation of the soft tissue around the implant body, thereby improving the health and durability of the soft and hard tissues after dental implant surgery.

DETAILED DESCRIPTION OF THE INVENTION

[0015] In order to make the objects, features and advantages of the present invention more clearly understood and appreciated, the following detailed description will be given by way of example with reference to the drawings in which:

[0016] First, as shown in Figures 1 and 2, the structure of an implant body to be implanted into bedrock bone includes an implant body 10, the outer surface of which has a threaded portion 11 and a smooth surface portion 12, the threaded portion 11 being roughened by sandblasting and acid etching, the length of the threaded portion 11 being between 7 mm and 9 mm, the diameter of the smooth surface portion 12 being smaller than the diameter of the threaded portion 11, and the length of the smooth surface portion 12 being between 2 mm and 7 mm, the surface of the smooth surface portion 12 being provided with a micro-threaded portion 121 at a position at least 1 mm away from the apex, the width of the micro-threaded portion 121 being between 1 mm and 2 mm, the micro-threaded portion 121 having a thread surface with a pitch width of 70 μm and a thread depth of 20 μm, and the surface of the smooth surface portion 12 being provided with an anodized oxide coating 122 by an anodized oxide coating process.

[0017] Further, as shown in FIGS. 1, 2 and 4, the threaded portion 11 has a shank whose diameter gradually decreases from top to bottom to form a conical axis 111. The threaded portion 11 forms a progressive thread along the conical axis 111, thinning and deepening toward the end. A terminal arc 112 is smoothly designed at the tip of the threaded portion. A fine threaded portion 13 is formed between the threaded portion 11 and the smooth surface portion 12. The diameter of the fine threaded portion 13 is smaller than that of the threaded portion 11 but larger than that of the smooth surface portion 12. The fine threaded portion 13 is also roughened by sandblasting and acid etching. A connecting platform 123 is formed at the top end of the smooth surface portion 12. A hexagonal hole 14 is formed along the connecting platform 123. A tapered hole 141 (Morse The tapered hole 141 has an outer inclination angle of 11 degrees with respect to the hexagonal hole 14 as a reference, and the hexagonal hole 14 has a first female thread portion 142 and a second female thread portion 143 formed therein. The diameter of the second female thread portion 143 is smaller than the diameter of the first female thread portion 142. In an implant body having a diameter of 4.5 mm to 5.0 mm, only the first female thread portion 142 is provided, and the diameter of the first female thread portion 142 is 20 mm.

[0018] 3A and 3B show examples of the implant body 10 of various sizes. As shown in FIG. 3A, the total length of the smooth surface portion 12 of the implant body 10 is 2 mm, which is shorter than the fine thread portion 121 of 1 mm width located 1 mm from the apex of the smooth surface portion 12, and the distance between the fine thread portion 13 and the fine thread portion 121 is shorter than the distance between the fine thread portion 121 and the connecting platform 123. As shown in FIG. 3B, the total length of the smooth surface portion 12 of the implant body 10 is 3 mm, which is shorter than the fine thread portion 121 of 15 mm width located 1 mm from the apex of the smooth surface portion 12, and the distance between the fine thread portion 13 and the fine thread portion 121 is shorter than the distance between the fine thread portion 121 and the connecting platform 123. As shown in FIG. 3B, The total length of the smooth surface portion 12 of the implant body 10 is 5 mm, which is shorter than the 2 mm wide micro-thread portion 121 located 1 mm from the apex of the smooth surface portion 12, and the distance between the fine thread portion 13 and the micro-thread portion 121 is greater than the distance between the micro-thread portion 121 and the connection platform 123. As shown in Figure 3(4), the total length of the smooth surface portion 12 of the implant body 10 is 7 mm, which is shorter than the 2 mm wide micro-thread portion 121 located 1 mm from the apex of the smooth surface portion 12, and the distance between the fine thread portion 13 and the micro-thread portion 121 is greater than the distance between the micro-thread portion 121 and the connection platform 123. However, the above sizes are only a part of the embodiments of the implant body 10 of the present invention and do not limit the scope of the present invention.

[0019] When this structure is actually used, as shown in FIG. 5, the implant body 10 is designed to be implanted into the dense and resistant to absorption of the jaw bone 20, rather than into the alveolar bone 21, which is easily absorbed or soft. Therefore, for patients whose alveolar bone 21 has already been severely atrophied, for example, when the right alveolar bone 21 shown in FIG. 5 has already been atrophied and is lower than the left alveolar bone 21, implant surgery can be performed without reconstructing the alveolar bone 21. Here, the screw of the implant body 10 The part 11 is designed with a self-tapping mechanism and can be directly screwed in, reducing the number of surgical procedures. Furthermore, the threaded part 11 has a gradual and inclined groove design, which allows the bone chips scraped off when the threaded part 11 is screwed in to be concentrated in the inclined groove, which helps the base bone 20 and the threaded part 11 to be connected together. Finally, the conical shaft 111, which is designed with a gradual reduction mechanism, allows the threaded part 11 to be screwed in smoothly, which is advantageous for screwing the implant body 10 into the base bone 20 of the patient and for connecting the threaded part 11 to the base bone 20. The threaded portion 11 is completely implanted in the pelvic bone 20, and the design of the terminal arc portion 112 at the end of the threaded portion 11 effectively reduces the risk of damaging anatomical structures such as nerves and blood vessels. Furthermore, when the threaded portion 11 is screwed into the base bone 20, the fine threaded portion 13 is screwed into the alveolar bone 21, which has already atrophied, and is roughened by sandblasting and acid etching so that the surface of the threaded portion 11 is not exposed from the gums 22 and is not in contact with each other, thereby avoiding contact between the threaded portion 11 and the gums 22. , because a roughened thread may cause inflammation of the soft tissue, and at the same time, it prevents food and debris from remaining on the threaded portion 11; the implant body 10 is configured so that only the smooth surface portion 12 does not extend outside the alveolar bone 21, but is covered by the gums 22; and the smooth surface portion 12 leads to the micro-threaded portion 121, which helps to closely adhere the outer periphery of the implant body 10 to the soft tissue of the gums 22, improves the sealing between the gums 22 and the implant body 10, and therefore reduces the risk of bacterial invasion; and also, in consideration of aesthetic factors,Similarly, surgical treatment for replacing bone and flesh can be performed using the smooth surface portion 12.

[0020] After the implant surgery of the implant body 10 is completed, a pillar 15 can be attached to the connection platform 123 of the smooth surface portion 12, and when the gums 22 heal, the gums will expand around the pillar 15, thereby further filling the gap between the connection platform 123 and the gums 22. After the gums 22 heal, a denture 16 can be attached, finally completing the implant surgery treatment.

[0021] The structure of the above specific embodiment provides the following advantages: the implant body 10 of the present invention is implanted deep into the basal bone, the threaded portion 11 can be completely implanted into the basal bone 20 and the alveolar bone 21, and the smooth surface portion 12 extends outward from the alveolar bone 21 to be adhered to and covered by the gums 22. This is particularly applicable to patients with atrophy of the alveolar bone 21, and eliminates the need for bone powder to reconstruct the alveolar bone 21. This reduces the need for complicated bone and flesh replacement surgery and shortens the painful period during implantation. At the same time, the threaded portion 11 can be prevented from coming into contact with the soft tissue of the gums 22 during bone powder repair, thereby avoiding inflammation. This significantly improves the success rate of implantation surgery for the implant body 10 and contributes to the health of the gums 22 tissue.

[0022] Furthermore, the smooth surface portion 12 is provided with the anodized coating 122 through an anodized coating process, which can effectively reduce the adhesion of plaque and is beneficial to gum health. If the area around the implant body 10 is suddenly inflamed and causes gingivitis, the smooth surface portion 12 is also easy to treat. Furthermore, the design of the micro-thread portion 121 of the smooth surface portion 12 promotes tight adhesion of the gum 22 soft tissue around the implant body 10, prevents bacterial invasion, and prevents inflammation of the soft tissue around the implant body, thereby improving the health and durability of the soft and hard tissues after dental implant surgery.

[0023] The above are only some of the embodiments of the present invention and are not intended to limit the scope of the present invention, i.e., any changes or modifications made within the scope of the utility model claims of the present invention shall also fall within the scope of the present invention.
