Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a healing scanning mechanism for dental implants and its installation method. Background Technology

[0002] Dental implants involve inserting an implant (artificial tooth root) into the alveolar bone in the area of ​​the missing tooth. After the implant has taken hold, a prosthesis is fabricated on top to complete the restoration. It significantly improves chewing function and feels comfortable, similar to natural teeth. Many complex clinical cases that are difficult to resolve with conventional dentures can achieve satisfactory results with dental implants. Due to the reliability and aesthetics of dental implant restorations, they have gained increasing recognition and favor from patients and medical professionals in the field of dentistry.

[0003] In related technologies, after implant placement surgery, refer to Figure 1 The healing abutment 1 is used to shape the gingiva and form a gingival cuff. The healing abutment is fixed to the implant 3 by the central stud 2. This allows medical staff to directly scan the marking arc surface formed by the positioning groove on the healing abutment 1 during subsequent scanning and model acquisition. The position of the healing abutment 1 is determined by the marking arc surface, which in turn determines the position of the connected implant 3. Three-dimensional data of the morphology and arrangement of the patient's teeth are obtained, and then a permanent abutment and crown are designed and manufactured.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: when fixing the central stud to the implant by passing it through the healing abutment, during the long healing process, due to the frequent biting activities in the oral cavity and the exposed upper end of the central stud, the force exerted on the upper end of the central stud during biting food can cause the central stud to delaminate, making the healing abutment prone to loosening and affecting subsequent scanning and gingival shaping. Summary of the Invention

[0005] To improve the stability of the healing scanning abutment, this application provides a healing scanning mechanism for dental implants and its installation method.

[0006] In a first aspect, this application provides a healing scanning mechanism for dental implants, which adopts the following technical solution: A healing scanning mechanism for dental implantation includes a healing scanning abutment and a fixation post; The healing scanning platform includes a healing part and a scanning part. The healing part and the scanning part are fixedly connected. A smooth transition surface is formed between the sidewalls of the healing part and the scanning part. The healing part is used to engage with the implant. The scanning part has a marking arc surface for scanning at one end away from the healing part. A fixing hole is coaxially opened in the healing scanning platform. The fixing post includes a support section and a fixing section, which are coaxially rotatably connected. The support section is used for threaded connection with the implant, and the fixing section extends into the fixing hole and is threadedly connected to the healing scanning abutment. The end of the fixing section away from the support section is provided with a hexagonal hole that extends into the support section.

[0007] By adopting the above technical solution, the healing scanning abutment is fixed to the implant via a fixing post. During the fixing process, the support section is threadedly connected to the implant, making the entire structure connected to the implant. Since the fixing section and the support section are coaxially rotatably connected, they form a single integrated structure. During installation, a hexagonal wrench inserted into the hexagonal hole can simultaneously rotate both the fixing section and the support section. The threaded connection between the fixing section and the healing scanning abutment achieves a comprehensive fixation effect. Even when biting food, a force is applied to the upper end of the fixing post, causing the fixing section to tend to rotate. However, due to the coaxial rotatable connection between the fixing section and the support section, it is difficult for the fixing section to drive the support section to rotate. When the support section does not rotate, the fixation effect of the fixing section is guaranteed. Thus, after the healing scanning abutment is fixed under the action of the fixing section and the support section, it is difficult for the threads to come loose, ensuring the stability of the healing scanning abutment fixation and preventing loosening of the healing scanning abutment, which would affect subsequent scanning and gingival shaping.

[0008] Optionally, a locking platform is provided in the fixing hole of the scanning section, which is used to limit the end of the fixing section away from the support section.

[0009] By adopting the above technical solution, the fixed segment is limited by the set clamp, which further improves the stability of the fixed segment. Under the action of the clamp, the fixed segment cannot move upward, thereby further improving the fixation stability of the fixed column on the healing scanning stage.

[0010] Optionally, the outer side of the fixing section is provided with an external thread, and the fixing hole is provided with an internal thread that matches the external thread on the fixing section. The end of the fixing section away from the support section abuts against the mounting plate.

[0011] By adopting the above technical solution, when fixing the healing scanning base, the external thread on the fixing section is directly connected to the internal thread in the fixing hole of the healing scanning base, thereby achieving the connection and fixing effect of the healing scanning base and making the installation and fixing of the healing scanning base more convenient.

[0012] Optionally, the scanning section is provided with a connecting cylinder, which is disposed on the mounting platform. The connecting cylinder is coaxially arranged with the fixing hole, and a gap is left between the outer wall of the connecting cylinder and the inner wall of the fixing hole. The end of the fixing section away from the support section is provided with an annular groove that mates with the connecting cylinder, and the connecting cylinder is threadedly connected to the fixing section.

[0013] By adopting the above technical solution, when fixing the healing scanning base, a connecting cylinder is set in the scanning section. When the fixed section is connected to the healing scanning base, the connecting cylinder extends into the annular groove and is threadedly connected to the fixed section. The outer wall of the fixed section is slidably connected to the inner wall of the fixing hole, which increases the contact area when the fixed section is connected to the healing scanning base, thereby increasing the friction between the fixed section and the healing scanning base, and further improving the stability of the connection and fixation of the healing scanning base.

[0014] Optionally, the scanning part and the healing part are detachably and fixedly connected.

[0015] By adopting the above technical solution and setting a detachable and fixed connection between the scanning unit and the healing unit, the healing unit can be replaced. By setting healing units of different heights, different oral conditions can be selected to meet the personalized needs of gingival morphology and further expand the applicability of the healing scanning mechanism.

[0016] Optionally, the scanning unit is provided with a connecting post, which is a prismatic structure. The connecting post is coaxially fixed to one end of the scanning unit near the healing unit. The end of the healing unit near the scanning unit is provided with a connecting groove that mates with the connecting post. The fixing hole passes through the connecting post.

[0017] By adopting the above technical solution, when installing the healing scanning mechanism, the connecting column at the bottom of the scanning unit is connected to the connecting groove on the healing unit, making the connection between the healing unit and the scanning unit more convenient. Furthermore, by setting the connecting column to be prismatic, relative rotation between the healing unit and the scanning unit can be avoided after they are connected, thereby ensuring the stability of the healing scanning platform and improving the accuracy of the subsequent scanning of implant interface data.

[0018] Optionally, the support segment is threadedly connected to the healing portion.

[0019] By adopting the above technical solution, when installing the healing scanning mechanism, the support section and the healing part are also connected by threads, so that the support section is connected to the implant and the healing part is fixed at the same time. The connection and fixation of the implant and the healing part by the support section further improves the stability of the healing scanning abutment.

[0020] Optionally, the fixed section is provided with a connecting ring at one end near the supporting section, and a retaining ridge is provided around the outer side of the connecting ring in the circumferential direction. The supporting section is provided with a limiting groove at one end near the fixed section that cooperates with the connecting ring and the retaining ridge.

[0021] By adopting the above technical solution, the connecting ring and the locking edge cooperate with the limiting groove, allowing the connecting ring and the locking edge to rotate within the limiting groove, thus achieving a rotating connection effect between the fixed section and the supporting section.

[0022] Secondly, this application provides a method for installing a healing scanning mechanism for dental implants, employing the following technical solution: A method for installing a healing scanning device for dental implants includes the following steps: S1: First, insert the hex wrench into the hexagonal hole and use the hex wrench to drive the support section and the fixing section to rotate simultaneously, so that the support section enters the implant. S2: Then place the healing scanning abutment on the implant, so that the fixation segment extends into the fixation hole, so that the healing part is engaged with the implant; S3: Fix the healing scanning abutment to the implant, pass a hex wrench through the fixing hole and insert it into the hexagonal hole. By inserting the hex wrench into the support section, the fixing section and the support section are driven to rotate simultaneously, causing the fixing post to move upward until the fixing section is connected and fixed to the healing scanning abutment.

[0023] By adopting the above technical solution, during the installation process, when the fixing post is first fixed to the implant and then the healing scanning abutment is fixed to the implant, the fixing post can guide the healing scanning abutment, making it easier for the healing scanning abutment to connect and engage with the implant. Finally, by rotating the fixing post, it is driven to move upward so that the fixing segment is connected and fixed to the healing scanning abutment. The whole installation is simple and easy to operate, with good connection stability and high installation efficiency.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting a fixed column including a support section and a fixed section, the support section and the fixed section are coaxially rotatably connected, and a hexagonal hole is set at the end of the fixed section away from the support section. The hexagonal hole extends into the support section. The fixed section is threadedly connected to the healing scanning base to achieve the overall fixation effect of the healing scanning base. Even if a force is formed on the upper end of the fixed column during the process of biting food, causing the fixed section to have a tendency to rotate, the fixed section is unlikely to drive the support section, thus ensuring the stability of the healing scanning base fixation. 2. By setting a connecting sleeve inside the scanning section, and the connecting sleeve being threadedly connected to the fixed section, the contact area when the fixed section is connected to the healing scanning stage is increased, thereby increasing the friction between the fixed section and the healing scanning stage, and further improving the stability of the connection and fixation of the healing scanning stage; 3. By setting a detachable and fixed connection between the scanning unit and the healing unit, and by connecting the connecting post at the bottom of the scanning unit with the connecting groove on the healing unit, the healing unit can be replaced. By setting healing units of different heights, different oral conditions can be selected to meet the personalized needs of gingival morphology. 4. Installation method: First, fix the fixing post into the implant, then fix the healing scanning abutment onto the implant. By rotating the fixing post, it is driven to move upward, so that the fixing segment is connected and fixed to the healing scanning abutment. The installation is simple and easy to operate, with good connection stability and high installation efficiency. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0034] Example 1 This application discloses a healing scanning mechanism for dental implants. (Refer to...) Figure 2 , Figure 3 as well as Figure 4 The healing scanning mechanism includes a healing scanning platform 4 and a fixing post 5. The healing scanning platform 4 includes a healing part 41 and a scanning part 42. Both the healing part 41 and the scanning part 42 are frustum-shaped structures. A smooth transition surface is formed between the sidewalls of the healing part 41 and the scanning part 42. The end of the healing part 41 away from the scanning part 42 is integrally connected to a locking section 412. The locking section 412 is a regular hexagonal prism. The implant 3 has a locking groove 31 that cooperates with the locking section 412. The healing part 41 is locked with the implant 3 through the locking section 412. After the healing part 41 and the implant 3 are locked, they can prevent relative rotation. The end of the scanning part 42 away from the healing part 41 is provided with a marking arc surface 421 for scanning by the oral scanner. The marking arc surface 421 includes several positioning grooves that correspond to the oral scanner. The healing scanning platform 4 has a fixing hole 43 coaxially opened in the healing scanning platform 4. The fixing post 5 fixes the healing scanning platform 4 through the fixing hole 43.

[0035] Reference Figure 4 and Figure 5 The scanning unit 42 and the healing unit 41 are detachably and fixedly connected, and the healing unit 41 can be replaced. By replacing the healing unit 41 with one of different heights, it is possible to select according to different oral conditions and meet the personalized needs of gingival morphology. A connecting post 424 is integrally connected to the scanning unit 42. The connecting post 424 is located at the end of the scanning unit 42 near the healing unit 41. The fixing hole 43 passes through the connecting post 424. In this embodiment, the connecting post 424 is a regular hexagonal prism structure. The connecting post 424 can be a square prism, pentagonal prism, or hexagonal prism, as long as it can prevent relative rotation after connecting with the healing unit 41. The end of the healing unit 41 near the scanning unit 42 is provided with a connecting groove 411 that cooperates with the connecting post 424. After the scanning unit 42 and the healing unit 41 are connected and fixed, relative rotation between the healing unit 41 and the scanning unit 42 can be avoided, thereby ensuring the stability of the healing scanning base 4.

[0036] Reference Figure 4 and Figure 5The fixing post 5 includes a support section 51 and a fixing section 52, which are coaxially rotatably connected. A connecting ring 522 is integrally connected to the end of the fixing section 52 near the support section 51. A retaining ridge 523 is integrally connected around the outer side of the connecting ring 522. A limiting groove 511 is provided at the end of the support section 51 near the fixing section 52, which cooperates with the connecting ring 522 and the retaining ridge 523, allowing the connecting ring 522 and the retaining ridge 523 to rotate within the limiting groove 511, thus achieving a rotatable connection between the fixing section 52 and the support section 51. A retaining platform 422 is provided within the fixing hole 43 of the scanning unit 42. The retaining platform 422 is used to limit the end of the fixing section 52 away from the support section 51. Under the action of the retaining platform 422, the fixing section 52 cannot move upward, improving the fixing stability of the fixing post 5 on the healing scanning base 4.

[0037] Reference Figure 4 and Figure 5 The support section 51 is threaded to the implant 3. The fixing section 52 extends into the fixing hole 43 and is threaded to the scanning unit 42. The outer end of the fixing section 52 away from the support section 51 has an external thread, and the end of the fixing hole 43 near the mounting platform 422 has an internal thread that mates with the external thread on the fixing section 52. The end of the fixing section 52 away from the support section 51 abuts against the mounting platform 422. A hexagonal hole 53 is provided at the end of the fixing section 52 away from the support section 51, extending into the support section 51. During installation, a hexagonal wrench can be inserted into the hexagonal hole 53 to simultaneously rotate both the fixing section 52 and the support section 51. The support section 51 is also threaded to the healing unit 41, allowing the support section 51 to connect and fix the healing unit 41 while simultaneously connecting to the implant 3. This connection and fixation of the implant 3 and the healing unit 41 by the support section 51 improves the stability of the healing scanning platform 4.

[0038] The implementation principle of a healing scanning mechanism for dental implants according to an embodiment of this application is as follows: During installation, the support section 51 is threadedly connected to the implant 3, and the fixed section 52 is threadedly connected to the healing scanning abutment 4 to achieve overall fixation of the healing scanning abutment 4. When oral activities such as biting food are performed, a force is generated on the upper end of the fixed post 5, causing the fixed section 52 to tend to rotate. Since the fixed section 52 and the support section 51 are coaxially rotatably connected, the fixed section 52 cannot drive the support section 51 to rotate, and the support section 51 does not rotate, thus ensuring the fixation of the fixed section 52 and avoiding the phenomenon of wire stripping. This prevents the healing scanning abutment 4 from becoming loose, which would affect subsequent scanning and gingival plasticity.

[0039] This application also discloses an installation method for a healing scanning mechanism for dental implants, referring to... Figure 5 The above-mentioned healing scanning mechanism for dental implants includes the following steps: S1: First, insert the hex wrench into the hexagonal hole 53 so that the hex wrench is inserted into the support section 51. Drive the support section 51 and the fixing section 52 to rotate simultaneously, so that the support section 51 enters the implant 3. S2: Then place the healing part 41 of the corresponding specification height on the implant 3 so that the healing part 41 and the implant 3 are engaged. Then place the scanning part 42 on the healing part 41 so that it is engaged. Insert the fixing section 52 into the fixing hole 43. S3: After fixing the scanning part 42 and the healing part 41 onto the implant 3, pass the hexagonal wrench through the fixing hole 43 above the scanning part 42 and insert it into the hexagonal hole 53. Then, insert the hexagonal wrench into the support section 51. Drive the fixing section 52 and the support section 51 to rotate in opposite directions at the same time using the hexagonal wrench, so that the fixing post 5 moves upward until the fixing section 52 is threadedly connected and fixed to the healing scanning base 4. Finally, remove the hexagonal wrench.

[0040] Example 2 The difference between this embodiment and Embodiment 1 is that, referring to... Figure 6 and Figure 7 A connecting cylinder 423 is provided inside the scanning unit 42. The connecting cylinder 423 is integrally connected to the mounting plate 422. The connecting cylinder 423 is coaxially arranged with the fixing hole 43. A gap is left between the outer wall of the connecting cylinder 423 and the inner wall of the fixing hole 43. An annular groove 521 that mates with the connecting cylinder 423 is opened at the end of the fixing section 52 away from the support section 51. The connecting cylinder 423 extends into the annular groove 521 and is threadedly connected to the fixing section 52. This increases the contact area when the fixing section 52 is connected to the healing scanning base 4, thereby increasing the friction between the fixing section 52 and the healing scanning base 4 and improving the stability of the connection and fixation of the healing scanning base 4.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
