Description

Technical Field

[0001] This invention relates to the field of dental implant medical devices, specifically a guide device (hereinafter referred to as a guide ring) used in conjunction with an implant guide plate for precisely preparing implant sockets in the alveolar bone. Background Technology

[0002] In digitally guided implant surgery, the guide ring is used in conjunction with the implant guide plate. The guide ring is usually fixed in the implant guide plate by adhesive or embedding. The guide ring plays a guiding role and plays a very important role in improving the accuracy of the surgery.

[0003] In the prior art, Chinese utility model patent CN219354219U (authorization announcement date: July 18, 2023, title: An implantation guide ring) discloses an implantation guide ring with several grooves on the outer ring. Although this structure can provide a certain axial fixation force, its anti-rotation ability is insufficient, and it is easy to loosen or rotate during the operation, affecting the accuracy of the operation.

[0004] In addition, existing technologies also include guide rings with knurled, threaded, or straight toothed structures on the outer wall, which are mainly used to improve friction. However, such structures are difficult to form a stable and continuous mechanical interlocking structure, especially in semi-open guide rings, where structural interruptions can easily lead to unstable anti-rotation performance.

[0005] Therefore, there is an urgent need for a new type of guide ring structure that can fundamentally enhance the fixation stability of the guide ring within the implantation guide plate, especially its anti-rotation ability, and can flexibly adapt to the needs of different clinical scenarios. Summary of the Invention

[0006] To address the technical problems of insufficient anti-rotation capability of existing implant guide rings and the tendency of semi-open guide rings to loosen and rotate during surgery due to incomplete structure, thus affecting surgical precision, this invention provides an implant guide ring with strong retention force, excellent anti-rotation performance, and can be adapted to both conventional dental implant surgery and dental implant surgery for patients with limited mouth opening. This solves the defects of poor mechanical interlocking between the guide ring and the implant guide plate and insufficient circumferential resistance in the existing technology.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A planting guide ring includes a guide ring body with a through guide channel inside. The outer wall surface of the guide ring body has a continuous and regular wavy texture. The continuous and regular wavy texture of this invention, with its periodic undulating structure, forms a series of uniformly distributed "micro-slopes" and "grooves" on a microscopic scale. When the adhesive material (such as resin) flows into the troughs and cures, these structures work together to: 1) significantly increase the effective bonding area, providing stronger static friction; 2) generate a mechanical interlocking effect: when the slopes on both sides of the crests are subjected to rotational shear force, they form a reverse supporting force with the cured adhesive material, preventing relative circumferential rotation between the guide ring and the guide plate. This makes it less likely for the guide ring to rotate relative to the other side when subjected to rotational force.

[0008] 3) Provides predictable drag torque: Due to the regularity and periodicity of the wavy texture, the anti-rotation drag it provides is uniform and calculable. By optimizing the ratio of wave height (H) to wavelength (L), the anti-rotation performance is maximized while ensuring the strength of the guide ring and without significantly increasing the diameter.

[0009] Furthermore, the wave-shaped texture is composed of periodically alternating convex peaks and concave troughs, and its cross-sectional profile is a smooth wave curve.

[0010] Preferably, the wave height of the wavy texture is 0.05mm-0.5mm, and the wavelength is 0.2mm-2.0mm. This invention is not limited to the above numerical ranges; those skilled in the art can adjust them according to the guide ring size and guide plate material.

[0011] In a preferred embodiment of the present invention, the guide ring body is cylindrical, and its outer wall is a cylindrical surface of equal diameter, with the wavy texture covering the entire outer wall surface. This design is compact and suitable for routine implantation surgery.

[0012] In another preferred embodiment of the invention, the side wall of the guide ring body is provided with an axially penetrating notch. This design facilitates lateral access of the drill bit when the patient's mouth opening is limited.

[0013] Preferably, the guide ring body is made of medical-grade stainless steel 316L or medical-grade titanium alloy TC4. The wavy texture is machined using a precision turning process. Beneficial effects

[0014] The implantation guide ring provided by this invention has at least the following beneficial effects: 1) Symmetrical equal-diameter implantation guide ring: compact structure with wavy texture covering the entire outer wall, suitable for the high precision requirements of conventional implantation surgery; 2) Semi-open implantation guide ring: overcomes the defect of sudden drop in retention force at the notch of the annular groove, achieves uniform retention in the circumferential range, and solves the problem of guide ring loosening caused by the lateral approach of the drill bit during surgery in patients with limited mouth opening.

[0022] The present invention will be further described below with reference to the accompanying drawings and through two preferred embodiments.

[0023] First embodiment (see Figures 1-3 ): This embodiment provides a symmetrical, equal-diameter planting guide ring for conventional planting. (See also...) Figure 1The planting guide ring includes a guide ring body (1), and a guide channel (11) is provided through the guide ring body (1). The inner diameter of the guide channel (11) is adapted to the outer diameter of the drill bit (99). The outer wall surface of the guide ring body (1) is integrally processed with continuous and regular wave-shaped texture (12). In this embodiment, the implant guide ring is a symmetrical, uniform-diameter cylindrical shape, with a continuous, regular wavy texture (12) machined on its outer surface. In clinical use, the guide ring is first fixed to a pre-prepared matching hole in the implant guide plate (98) using adhesive material. The adhesive material fully fills the wavy texture (12), and after curing, forms a strong mechanical interlock. Subsequently, the implant guide plate (98) with the guide ring (1) assembled is attached to the alveolar bone of the patient. (See reference...) Figure 3 This allows the location of the hole to be drilled to be determined. During the procedure, the drill bit (99) descends along the guide channel (11) inside the guide ring. During this process, the drill bit generates rotational force, and the wavy texture structure on the outer wall of the guide ring provides a stable and strong reverse resistance torque through interlocking with the guide plate material, effectively preventing the guide ring from loosening or shifting, thereby ensuring the accuracy of the planting hole preparation.

[0024] Second embodiment (see Figures 4-6 ): This embodiment provides a semi-open implantation guide ring for patients with limited mouth opening. See also... Figure 4 The planting guide ring includes a guide ring body (2), a guide channel (21) is provided through the guide ring body (2), the inner diameter of the guide channel (21) is adapted to the outer diameter of the drill bit (99), the outer wall surface of the guide ring body (2) is processed with a continuous and regular wave-shaped texture (22), and a semi-opening (23) is provided through one side of the guide channel 21. In this embodiment, the implant guide ring is a semi-open cylindrical shape, and its outer surface is integrally machined with a continuous and regular wavy texture (22). In clinical use, the guide ring (2) is first fixed to the pre-prepared matching hole in the implant guide plate (98) using adhesive material. The adhesive material fully fills the wavy texture (22), and after curing, forms a strong mechanical interlock. Subsequently, the implant guide plate (98) with the guide ring (2) assembled is attached to the alveolar bone of the patient. (See reference...) Figure 6 This allows us to locate the position where we need to drill.

[0025] During the procedure, the drill bit (99) moves from the semi-open (23) side of the guide ring body (2) on the implantation guide plate (98) to the guide channel (21) of the guide ring body (2) to drill a hole. During this process, the drill bit generates rotational force. The wavy texture structure on the outer wall of the guide ring provides a stable and strong reverse resistance torque through interlocking with the guide plate material, effectively preventing the guide ring from loosening or shifting, thereby ensuring the accuracy of implantation cavity preparation. Compared with existing semi-open implantation guide rings with annular grooves on the surface, the continuous wavy texture structure on the outer peripheral surface can significantly increase the surface area and adhesion of the adhesive material, and improve the retention force of the connection between the guide ring and the guide plate. It effectively improves anti-rotational stability and enhances the accuracy and safety of implantation surgery. In summary, this invention, by introducing a "wavy texture" as the core retention structure, has developed two high-performance implantation guide rings specifically designed for the clinical needs of patients with conventional and limited mouth opening. Both embodiments demonstrate the inventive concept of improving macroscopic mechanical properties through innovative surface micro-geometry, possessing practical value and inventiveness.
