Description

Technical Field

[0001] This application belongs to the field of oral restoration technology, specifically relating to an assistive device for immediate temporary tooth placement. Background Technology

[0002] In existing technologies, the immediate temporary tooth placement device is a key support for immediate implant and immediate restoration techniques. This technology has been widely used in clinical practice due to its ability to shorten treatment time and quickly restore the aesthetics and chewing function of patients' teeth. Its core principle is to place a pre-formed temporary tooth within two hours of implant placement, which can immediately restore chewing function, protect alveolar bone, and improve patient comfort. The placement device directly affects the accuracy and treatment outcome of this crown placement process.

[0003] However, current methods of temporary tooth placement have significant drawbacks: they rely heavily on the dentist's vision, touch, or simple guiding tools, making it difficult to accurately determine the placement path due to limited oral field of vision; if the pre-formed temporary tooth's transgingival morphology does not match the soft tissue, it can easily interfere with placement; inaccurate placement can also lead to a loose connection between the prosthesis and abutment, creating microgaps, causing screw loosening, prosthesis breakage, affecting soft tissue shaping, and even leading to treatment failure. Although digital surgical guides can precisely guide implant placement, current technology lacks a dedicated device for locating both the "implant position" and the "final placement position of the temporary tooth," preventing the precision advantage of implant placement from extending to the placement stage, thus limiting treatment outcomes.

[0004] Therefore, the development of high-precision assisted immediate temporary tooth placement devices to achieve full-process precision control, improve treatment outcomes and patient satisfaction has become an urgent need in the industry. Utility Model Content

[0005] In order to address the technical problems in the prior art of immediate implantation and immediate restoration techniques, where the placement of temporary teeth relies on the doctor's vision, touch, or simple tools, the placement path is difficult to accurately determine due to limited oral field of vision, and the temporary teeth are easily interfered with by soft tissue, resulting in low implantation accuracy and poor oral restoration effect, this application proposes an auxiliary device for immediate temporary tooth placement.

[0006] This application adopts the following solution: an auxiliary immediate temporary tooth placement device, including a positioning mechanism and a temporary tooth body disposed on the positioning mechanism, the temporary tooth body being disposed on a preset implant area, the positioning mechanism including a first positioning member disposed on a tooth body adjacent to the preset implant area, a second positioning member disposed on another adjacent tooth body in the preset implant area, and a connecting component disposed between the first positioning member and the second positioning member, the temporary tooth body being disposed on the connecting component and located between the first positioning member and the second positioning member.

[0007] In some feasible embodiments, the first positioning member includes a first positioning seat and a first positioning groove disposed on the first positioning seat. The cross-sectional shape of the first positioning groove matches the cross-sectional shape of the adjacent tooth of the preset implant area, and the adjacent tooth of the preset implant area can be matched to extend into the first positioning groove.

[0008] In some feasible embodiments, the second positioning member includes a second positioning seat and a second positioning groove disposed on the second positioning seat. The cross-sectional shape of the second positioning groove matches the cross-sectional shape of another adjacent tooth in the preset implant area, and the other adjacent tooth in the preset implant area can be matched and extended into the second positioning groove.

[0009] In some feasible embodiments, the width of the first positioning seat is defined as W, and the width of the adjacent tooth in the implant area is preset as w. The W and the w satisfy the following relationship: 0.5≤W / w≤0.8.

[0011] In some feasible embodiments, the second connecting post group includes a plurality of second connecting posts spaced apart along the length direction of the first connecting post.

[0012] In some feasible embodiments, the cross-sectional area of ​​the second connecting post gradually decreases from the direction closer to the first connecting post to the direction farther away from the first connecting post.

[0013] In some feasible embodiments, the temporary tooth includes a tooth body and a connecting hole provided on the tooth body.

[0014] In some feasible embodiments, the positioning mechanism is integrally formed with the temporary tooth.

[0023] Combination Figures 1 to 6 The following description further illustrates the technical solution proposed in this application. This application adopts the following technical solution: an auxiliary immediate temporary tooth placement device, comprising a positioning mechanism 1 and a temporary tooth 2 disposed on the positioning mechanism 1, the temporary tooth 2 being disposed on a preset implantation area. The positioning mechanism 1 includes a first positioning element 3 disposed on a tooth adjacent to the preset implantation area, a second positioning element 4 disposed on another adjacent tooth in the preset implantation area, and a connecting component 5 disposed between the first positioning element 3 and the second positioning element 4. The temporary tooth 2 is disposed on the connecting component 5 and located between the first positioning element 3 and the second positioning element 4.

[0024] This application provides an assistive device for immediate temporary tooth placement, comprising a positioning mechanism and a temporary tooth body disposed on the positioning mechanism. The temporary tooth body is disposed on a pre-designed implantation area. The positioning mechanism includes a first positioning element disposed on a tooth adjacent to the pre-designed implantation area, a second positioning element disposed on another tooth adjacent to the pre-designed implantation area, and a connecting component disposed between the first and second positioning elements. The temporary tooth body is disposed on the connecting component and located between the first and second positioning elements. By establishing a stable reference based on adjacent natural teeth through the first and second positioning elements, the implantation accuracy of the temporary tooth body can be effectively improved, enabling rapid positioning and implantation without relying on the doctor's experience. The connecting component carries the temporary tooth body and is disposed between the first and second positioning elements, preventing displacement of the temporary tooth body during the implantation process. This application has the advantages of simple structure, convenient operation, improved quality of immediate implant restoration, and ease of promotion and implementation.

[0025] In actual implementation, during oral implant surgery, the temporary tooth is placed within the pre-designated implant area. The pre-designated implant area (i.e., the edentulous area where the temporary tooth needs to be implanted) usually has healthy natural teeth on both sides (adjacent teeth to the pre-designated implant area). The device first uses the first positioning element 3 and the second positioning element 4 to position itself relative to the natural teeth on both sides of the edentulous area, effectively determining the installation reference for the temporary tooth.

[0026] In actual implementation, the positioning slot of the positioning device is precisely matched with the tooth shape of the natural tooth. The morphological interlocking structure can effectively limit the displacement and shaking of the positioning device during the surgical operation, ensuring positioning stability.

[0027] In actual implementation, the connecting component is integrally formed with the first positioning component and the second positioning component. During the positioning process, the positioning mechanism and the temporary tooth form an integral rigid structure to avoid angular displacement or positional misalignment of the temporary tooth during the operation (such as gingival traction or instrument contact).

[0028] In this embodiment, the first positioning member 3 includes a first positioning seat 30 and a first positioning groove 31 disposed on the first positioning seat 30. The cross-sectional shape of the first positioning groove 31 matches the cross-sectional shape of the adjacent tooth in the preset implant area, and the adjacent tooth in the preset implant area can be matched and extended into the first positioning groove 31.

[0029] In this embodiment, the second positioning member 4 includes a second positioning seat 40 and a second positioning groove 41 disposed on the second positioning seat 40. The cross-sectional shape of the second positioning groove 41 matches the cross-sectional shape of another adjacent tooth in the preset implantation area, and the other adjacent tooth in the preset implantation area can be matched and extended into the second positioning groove 41.

[0030] In actual implementation, the cross-sectional shapes of the first and second positioning grooves are designed based on the patient's oral cavity scan results and are prepared using 3D printing technology, which can further improve the positioning accuracy of the positioning mechanism.

[0031] In this embodiment, the width of the first positioning seat 30 is defined as W, and the width of the adjacent tooth in the implantation area is preset as w. The W and the w satisfy the following relationship: 0.5≤W / w≤0.8.

[0032] In actual implementation, by designing the width of the first positioning seat, when the adjacent teeth of the preset implant area are matched and extended into the first positioning slot, the fit between the adjacent teeth of the preset implant area and the first positioning slot can be observed to determine whether the first positioning component is installed in place, thereby further ensuring the implantation accuracy of the temporary teeth.

[0033] In this embodiment, the connecting component 5 includes a first connecting post 50 with one end disposed on the first positioning member 3 and the other end disposed on the second positioning member 4, and a second connecting post group 51 disposed on the first connecting post 50. The second connecting post group 51 extends toward the preset implantation area, and the temporary tooth 2 is disposed on the second connecting post group 51.

[0034] In this embodiment, the second connecting post group 51 includes a plurality of second connecting posts 52 spaced apart along the length direction of the first connecting post 50.

[0035] In this embodiment, the cross-sectional area of ​​the second connecting post 52 gradually decreases from near the first connecting post 50 to away from the first connecting post 50.

[0036] In this embodiment, the temporary tooth 2 includes a tooth 20 and a connecting hole 21 provided on the tooth 20.

[0037] In this embodiment, the positioning mechanism 1 and the temporary tooth 2 are integrally formed.

[0038] In actual implementation, by designing the cross-sectional area of ​​the second connecting post (gradually decreasing from near the first connecting post to far away), after the temporary tooth is installed, the second connecting post can be cut off at the end near the temporary tooth, removing the remaining part of the positioning mechanism. This allows the temporary tooth to be independently fixed to the target implant area, thereby achieving independent, stable fixation and flexible installation of the temporary tooth.

[0039] In actual implementation, both the temporary tooth and the positioning component were prepared using 3D printing technology.

[0040] In actual implementation, both the temporary tooth and the positioning component are made of resin.

[0041] This application provides an assistive device for immediate temporary tooth placement, comprising a positioning mechanism and a temporary tooth body disposed on the positioning mechanism. The temporary tooth body is disposed on a pre-designed implantation area. The positioning mechanism includes a first positioning element disposed on a tooth adjacent to the pre-designed implantation area, a second positioning element disposed on another tooth adjacent to the pre-designed implantation area, and a connecting component disposed between the first and second positioning elements. The temporary tooth body is disposed on the connecting component and located between the first and second positioning elements. By establishing a stable reference based on adjacent natural teeth through the first and second positioning elements, the implantation accuracy of the temporary tooth body can be effectively improved, enabling rapid positioning and implantation without relying on the doctor's experience. The connecting component carries the temporary tooth body and is disposed between the first and second positioning elements, preventing displacement of the temporary tooth body during the implantation process. This application has the advantages of simple structure, convenient operation, improved quality of immediate implant restoration, and ease of promotion and implementation.
