Description

Technical Field

[0001] This utility model belongs to the field of oral medical device technology, specifically relating to a one-piece dental implant. Background Technology

[0002] Dental implants are a restorative solution used to replace missing teeth. They are suitable for the loss of one or more teeth due to cavities, periodontal disease, trauma, etc., as well as for improving chewing function, pronunciation and facial contours, or for improving the stability and comfort of wearing removable dentures.

[0003] Dental implants involve surgically inserting artificial tooth roots into the maxilla or mandible to provide stable support for the artificial crown. Traditionally, this process involves two main stages: first, surgery is performed to implant the implant into the jawbone, allowing several months for the implant to integrate with the bone tissue—a process known as osseointegration; then, after confirming successful integration, a second surgery is performed to install the connectors and the final artificial crown.

[0004] However, the two steps described above require two separate surgeries. The first step has a longer healing period, resulting in a longer overall treatment cycle. This increases the patient's waiting time and psychological burden, and may also increase the risk of infection and postoperative discomfort due to multiple surgeries. Furthermore, the longer healing time means that patients cannot fully restore normal chewing function and aesthetic requirements during this period, which negatively impacts their quality of life. Therefore, improvements are needed. Utility Model Content

[0028] Referring to Figures 1 to 5 ​​The utility model discloses a one -segment type tooth implant, implantation section 1, abutment gong segment 2 and abutment retention section 3 that are arranged in proper order from below to above, further, implantation section 1, abutment gong segment 2 and abutment retention section 3 are integrally formed structure, the body of implantation section 1 is equipped with thread, the bottom of implantation section 1 is equipped with anti -rotation part 4, the longitudinal section of abutment gong segment 2 is trapezoidal, the body of abutment retention section 3 is equipped with identification face 5, and the joint of abutment gong segment 2 and abutment retention section 3 is installed with buffer pad (not shown in the figure). Specifically, implantation section 1 is firmly screwed into and fixed in the jaw bone of patient through the thread of its body part, provides firm basic support, and the anti -rotation part 4 at the bottom is used to enhance the ability of implant to resist rotation, ensures that implantation section and bone tissue are closely combined. Abutment gong segment 2 is used to connect implantation section 1 and the soft tissue inside oral cavity, and the trapezoidal longitudinal section design of abutment gong segment 2 helps to maintain correct gingival profile, helps to guide the natural healing of soft tissue and forms a healthy biological closed environment. Abutment retention section 3 is located on abutment gong segment 2 and is used to connect artificial tooth crown. Further, identification face 5 can provide the information such as direction, position and model of implant for doctors, and the like Figure 3 A of the like is the installation area of buffer pad, when implant is implanted, needs to assemble tooth crown at abutment retention section 3, and buffer pad can reduce the wear of tooth crown and abutment gong segment 2, and plays the role of buffering when occlusion. In addition, implantation section 1, abutment gong segment 2 and abutment retention section 3 adopt integrally formed structure, can cooperate with the existing one -segment type implant tooth method, when one -segment type implant surgery is carried out, stomatological physician only needs to implant the artificial tooth root and repair abutment part combined with bone tissue once, can install tooth crown after obtaining firm bone support. This integrated design avoids the long healing waiting and additional risk and discomfort caused by multiple operations brought by stage operation, thereby greatly shortens the treatment cycle and alleviates the pain of patients.

[0029] Further, the joint of abutment gong segment 2 and abutment retention section 3 is equipped with convex step 6, and the diameter of convex step 6 is between the diameter of abutment gong segment 2 and the diameter of abutment retention section 3, and buffer pad is sleeved on the outside of convex step 6. Specifically, taking Figure 3 For example, the drawing is applied to the implant of posterior tooth, and buffer pad is arranged at Figure 3At A, the cushion pad is usually applied to the posterior implant in the posterior teeth area which needs to bear larger occlusal force, because the posterior teeth area is the main part responsible for mastication function, and the occlusal force is much larger than that of the anterior teeth area, therefore, the implant installed at this position must be able to effectively cope with the high strength occlusal pressure, the cushion pad is sleeved outside the convex step 6 at the joint of the abutment transgingival segment 2 and the abutment retention segment 3, and its main role is to absorb and disperse the force from the occlusion process. The cushion pad reduces the pressure on the implant when occluding, and also reduces the impact on the surrounding soft tissue (such as the gums) and hard tissue (such as the jaw bone), which helps to maintain a healthy oral environment and prevent inflammation or damage caused by excessive pressure; and reduces the wear between the bottom of the crown and the abutment retention segment 3, prolonging the service life of the implant. And the convex step 6 ensures that the cushion pad can be stably positioned in its correct position, ensuring the effectiveness of the cushion pad under stress.

[0030] In the present embodiment, the longitudinal section of the abutment retention segment 3 is a regular polygon, and the shape of the longitudinal section includes a square or a regular hexagon. As shown in Figure 5 , the identification surface 5 is located on the side surface of the abutment retention segment 3, and the longitudinal section of the abutment retention segment 3 is configured as a regular hexagon, and generally, the implant of the abutment retention segment 3 with this shape is used for posterior tooth implantation; similarly, as shown in Figure 4 , the longitudinal section of the abutment retention segment 3 is configured as a square, and generally, the implant of the abutment retention segment 3 with this shape is used for anterior tooth implantation; the doctor can obtain the model of the implant through the identification surface 5.

[0031] Further, the top of the abutment retention segment 3 is provided with a scanning marker point 7 to facilitate accurate data collection using an intraoral scanner or other imaging equipment.

[0032] Preferably, the height of the implant segment 1 is 4.0mm-18.0mm, and the width of the implant segment 1 is 2.5mm-7.5mm.

[0033] Preferably, the height of the abutment transgingival segment 2 is 0.5mm-8.5mm, and the width of the abutment transgingival segment 2 is 2.8mm-10mm.

[0034] Preferably, the height of the abutment retention segment 3 is 2.0mm-10.0mm, and the width of the abutment retention segment 3 is 3.0mm-7.5mm.

[0035] Preferably, the materials of the implant section 1, the abutment transgingival section 2 and the abutment retention section 3 are pure titanium or titanium alloy. Specifically, the implant (the implant section 1, the abutment transgingival section 2 and the abutment retention section 3) is made of TA3, TA4 (Grade 4) pure titanium material in accordance with GB / T 13810 / ISO 5832-2 / ASTM F67, or TC4 ELI or TC4 titanium alloy in accordance with GB / T 13810 / IS0 5832-3 / ASTM F136, which has good biocompatibility and corrosion resistance.

[0036] Further, the implant surface is treated by acid etching and sandblasting to increase the surface roughness and promote osseointegration, and the sandblasting further increases the surface roughness by spraying small particles to enhance the mechanical interlocking between the implant and the bone tissue.

[0037] It should be noted that the implant accessory surface can be optionally treated or not treated, and the surface treatment methods include coloring anodic oxidation, TiN coating and DLC coating.

[0038] The one-section dental implant body and the one-section dental implant method of the utility model fuse the traditional implant section 1, the abutment transgingival section 2, the abutment retention section 3 and the scanning rod into one, and the abutment retention section 3 is provided with an identification surface 5, which can be used to identify the model of the implant body. During treatment, the doctor will implant the implant section 1, the abutment transgingival section 2 and the abutment retention section 3 combined with the bone tissue at one time, and the traditional two-stage surgical process is reduced to one-stage surgical process. After obtaining the stable bone support force, the dental crown can be directly installed at the abutment retention section 3. This dental implant body can simplify the surgical process, shorten the treatment period, and reduce the pain and psychological pressure of the patient. In addition, the buffer pad is added at the connection between the abutment transgingival section 2 and the abutment retention section 3 to reduce the pressure of the dental crown on the abutment transgingival section 2 during occlusion, and effectively alleviate the abrasion degree of the bottom of the dental crown and the abutment transgingival section 2 during long-term use.

[0039] The above only describes the preferred embodiments of the utility model, and does not limit the utility model. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
