Description

Technical Field

[0001] This disclosure relates to the field of dental implant technology, and in particular to a modular dental implant structure and implantation mechanism. Background Technology

[0002] When performing dental implant surgery, the necrotic pulp is first removed until a hollow space, i.e., the alveolar bone, is formed. Then, the implant is placed into the alveolar bone, and the implant is connected to the alveolar bone by the external threads on its periphery.

[0003] However, when placing an implant into the alveolar bone, the size of the implant must be determined based on the diameter of the alveolar bone. If the implant is too thick, it may damage the roots of adjacent teeth or important nerves and blood vessels. If the implant is too thin, it will result in a small contact area with the bone tissue, making it impossible to form good osseointegration. Thus, the current dental implant procedure is relatively complicated. Utility Model Content

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a simplified dental implant procedure that does not require the use of implants, a modular dental implant structure and implantation mechanism.

[0005] The purpose of this disclosure is achieved through the following technical solution: A modular dental implant structure includes a filling body, an implant screw, and a pre-installed component. The filling body is used to fill an alveolar cavity within a tooth root and has a threaded hole. The implant screw includes a threaded portion and a pre-installed portion. A connecting rib protrudes from the outer periphery of the pre-installed portion, and the threaded portion is located within the threaded hole, allowing the implant screw to be connected to the filling body via the threaded portion. The pre-installed component includes a first connecting portion, a transition portion, and a second connecting portion connected in sequence. The first connecting portion has a pre-installed groove, and the connecting rib abuts against the inner wall of the pre-installed groove, allowing the pre-installed component to be detachably connected to the implant screw. The second connecting portion is used for detachably connecting to an implant clamp. The pre-installed component is designed to detach from the implant screw when it is connected to the filling body.

[0006] In one embodiment, the connecting rib has a frosted portion that abuts against the inner wall of the pre-installed groove.

[0007] In one embodiment, the axial length of the threaded portion is 8-9 mm.

[0008] In one embodiment, the length of the threaded portion is 8 mm.

[0009] In one embodiment, the cross-sectional diameter of the pre-assembled part is 4-4.5 mm.

[0010] In one embodiment, the filler is a photocurable resin filler.

[0011] In one embodiment, the axial length of the second connecting portion is greater than the axial length of the transition portion.

[0012] In one embodiment, the outer peripheral wall of the second connecting portion has multiple abutment surfaces.

[0013] In one embodiment, the first connecting portion, the transition portion, and the second connecting portion are integrally formed.

[0014] A dental implantation device, comprising the modular dental implantation structure described in any of the embodiments.

[0015] Compared with the prior art, this disclosure has at least the following advantages: After removing the necrotic pulp, the cavity in the root canal is filled with filling material. Once the filling material forms a filling body, a pre-assembled part is held in place by an implant clamp so that the implant screw can be installed on the filling body. After the implant screw is installed, the pre-assembled part is removed so that subsequent steps can proceed normally. During this process, the implant body is no longer needed, which simplifies the implant procedure and improves the efficiency of implant treatment. Attached Figure Description

Detailed Implementation

[0019] To facilitate understanding of this disclosure, a more complete description will be given below with reference to the accompanying drawings, which illustrate preferred embodiments of the present disclosure. However, this disclosure can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments: Please see Figures 1 to 4 This is a combined dental implant structure 10 according to an embodiment of the present invention, comprising a filling body 100, an implant screw 200, and a pre-installed component 300. The filling body 100 is used to fill the alveolar ridge opened in the tooth root, and the filling body 100 has a threaded hole 101. The implant screw 200 includes a threaded portion 210 and a pre-installed portion 220. A connecting rib 221 protrudes from the outer periphery of the pre-installed portion 220. The threaded portion 210 is located in the threaded hole 101, so that the implant screw 200 is connected to the filling body 100 through the threaded portion 210. 00; The pre-assembly 300 includes a first connecting part 310, a transition part 320 and a second connecting part 330 connected in sequence. The first connecting part 310 has a pre-assembly groove 311. The connecting rib 221 abuts against the inner wall of the pre-assembly groove 311 so that the pre-assembly 300 can be detachably connected to the implant screw 200. The second connecting part 330 is used to detachably connect to the implant clamp. The pre-assembly 300 is used to detach from the implant screw 200 when the implant screw 200 is connected to the filling body 100.

[0023] In the above embodiments, after removing the necrotic pulp, the cavity in the tooth root is first filled with filling material. After the filling material forms the filling body 100, the pre-installed part 300 is clamped with a dental implant clamp so that the implant screw 200 is installed on the filling body 100. After the implant screw 200 is installed, the pre-installed part 300 is removed so that subsequent steps can be carried out normally. During this process, the implant is no longer required, thus simplifying the dental implant procedure and improving the efficiency of dental implant treatment.

[0024] It is understandable that when necrotic pulp is present in the tooth root, the necrotic pulp is first removed, at which point the tooth root forms an alveolar ridge. Then, filling material is inserted into the alveolar ridge, and during this process, the filling material hardens to form a filling body 100. Subsequently, a pre-assembled structure, including an implant screw 200 and a pre-assembled component 300, is held in place using an implant clamp. The implant screw 200 is inserted into the filling body 100, specifically through its threaded portion 210 connecting to the filling material. After the implant screw 200 is fixed, the pre-assembled component 300 is removed, detaching the implant screw 200 from the pre-assembled component 300. This eliminates the need for implant placement, thus simplifying the implant procedure. Furthermore, during the installation of the implant screw 200, the connecting rib 221 protruding from the outer periphery of the pre-assembled portion 220 abuts against the inner wall of the pre-assembled groove 311, ensuring that the implant screw 200 engages with the pre-assembled component 300. This prevents the implant screw 200 from falling off itself when the pre-assembled component 300 is held in place.

[0025] like Figure 3 As shown, in one embodiment, the connecting rib 221 has a frosted portion 221a, which abuts against the inner wall of the pre-installation groove 311 to increase the friction when the connecting rib 221 abuts against the inner wall of the pre-installation groove 311, thereby preventing the situation where the planting screw 200 and the pre-installation part 300 are connected but easily slip when the planting screw 200 is installed.

[0026] In one embodiment, the axial length of the threaded portion 210 is 8-9 mm. In this embodiment, the axial length of the threaded portion 210 is 8 mm.

[0027] In one embodiment, the cross-sectional diameter of the pre-assembly portion 220 is 4-4.5 mm. In this embodiment, the cross-sectional diameter of the pre-assembly portion 220 is 4 mm.

[0028] In one embodiment, the filler 100 is a light-cured resin filler. After the filler is inserted into the alveolar bone of the tooth root, the UV light irradiation step accelerates the curing of the filler, thereby accelerating the formation of the filler 100. This allows the implant screw 200 to be installed in the filler 100 earlier, thus reducing the implant procedure time.

[0029] In one embodiment, the axial length of the second connecting portion 330 is greater than the axial length of the transition portion 320, so that the contact area between the clamping portion of the implant clamp or other implant aid tool and the second transition portion 320 is larger, thereby enabling the implant clamp or other implant aid tool to better clamp the pre-installed part 300, so that the implant screw 200 can be reliably installed in the filler 100.

[0030] like Figure 3 As shown, in one embodiment, the outer peripheral wall of the second connecting portion 330 has multiple abutment surfaces 331, so that the implant clamp or other implant-assisted tool can better clamp the outer wall of the second connecting portion 330. That is, the clamping part of the implant clamp or other implant-assisted tool abuts against the multiple abutment surfaces 331, thereby ensuring that the implant screw 200 can be reliably installed in the filling body 100. Specifically, when the outer peripheral wall of the second connecting portion 330 has 4 abutment surfaces 331, the second connecting portion 330 is cuboid in shape; when the outer peripheral wall of the second connecting portion 330 has 6 abutment surfaces 331, the second connecting portion 330 is regular hexagonal prism in shape.

[0031] In one embodiment, the first connecting portion 310, the transition portion 320 and the second connecting portion 330 are integrally formed to make the connection between the first connecting portion 310, the transition portion 320 and the second connecting portion 330 more reliable and the structure more compact.

[0032] This disclosure also provides a dental implantation mechanism, including the modular dental implantation structure 10 described in any embodiment.

[0033] Compared with the prior art, this disclosure has at least the following advantages: After removing the necrotic pulp, the cavity in the root canal is filled with filling material. Once the filling material forms a filling body 100, a pre-installed component 300 is held in place by an implant clamp so that the implant screw 200 can be installed on the filling body 100. After the implant screw 200 is installed, the pre-installed component 300 is removed so that subsequent steps can proceed normally. During this process, the implant is no longer required, thus simplifying the implant procedure and improving the efficiency of implant treatment.

[0034] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
