Description

Technical Field

[0001] This invention relates to the field of oral implant technology, and in particular to a dual-channel guide plate system for immediate implantation in the anterior aesthetic zone and posterior zone. Background Technology

[0002] Compared to delayed implantation, immediate implantation can effectively shorten the treatment cycle, reduce the number of surgeries, and help preserve the bone volume of the alveolar bone and the morphology of the soft tissue. It is especially important for the anterior teeth region, which has extremely high aesthetic requirements, and the posterior teeth region, which has a heavy functional load.

[0003] To achieve precise implant placement and ensure optimal axial and initial stability, digital surgical guide technology is widely used in clinical practice. Existing digital implant guide systems typically include preoperative planning software, the guide itself, and accompanying surgical tools. In clinical applications, current guide structures are usually designed as full-coverage or open-window designs. For example, a common structure utilizes the entire dentition as support, with the guide covering the surface of the affected tooth. The dentist, guided by the guide, first extracts the tooth using specially designed extraction socket preparation tools, and then uses the same guide for socket preparation and implant placement. However, existing immediate implant guides have the following technical shortcomings in actual clinical applications, especially when considering the different biomechanical environments of the anterior aesthetic zone and the posterior zone: existing guides typically employ a single guide channel design, lacking effective guidance for the precision of instrument manipulation, and struggle to maintain their mechanical stability during critical steps. This leads to deviations in the use of surgical instruments, failing to meet the clinical needs for high-precision immediate implantation in the anterior aesthetic zone and the posterior zone. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a dual-channel guide plate system for immediate implantation in the anterior aesthetic zone and posterior zone.

[0005] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or to describe the scope of protection of these embodiments.

[0006] The present invention adopts the following technical solution: This invention provides a dual-channel guide plate system for immediate implantation in the anterior aesthetic zone and posterior zone, comprising: An implantation guide plate body is configured to cover the patient's surgical area, and the implantation guide plate body has dual channels, including a sliding operation channel for guiding instruments and an auxiliary positioning channel arranged in parallel with the sliding operation channel; A guide plate support device is installed at the patient's gums to fix the implant guide plate body in a preset position inside the patient's mouth. A guide rail plate is disposed on the guide plate support device, and a guide rail groove is formed on the guide rail plate; Several press-fit guide rings are used to support surgical instruments. Each press-fit guide ring is provided with a sliding column embedded in the guide rail groove, a stabilizing sleeve embedded in the auxiliary positioning channel, and an annular body located above the sliding operation channel.

[0007] Furthermore, the guide plate support device includes: a support plate body and several blocks; the support plate body is disposed at the patient's gums, and the blocks and the guide rail are disposed on the support plate body, with mounting grooves formed on the blocks.

[0008] Furthermore, the planting guide plate body is provided with a plurality of columns at positions corresponding to the platform, and the end of the column is provided with an installation insert adapted to the installation groove.

Detailed Implementation

[0016] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0017] like Figure 1-3 As shown in some illustrative embodiments, a dual-channel guide plate system for immediate implantation in the anterior aesthetic zone and posterior zone is provided. By combining the dual-channel structure with a sliding push-in guide ring 400, precise implantation in the anterior aesthetic zone and complex internal lifting operations in the posterior zone are achieved, while significantly improving the stability of the surgical procedure.

[0018] The dual-channel guide plate system includes: a planting guide plate body 100, a guide plate support device 200, a guide rail plate 300, and several press-fit guide rings 400.

[0019] The implant guide body 100 is digitally manufactured based on the patient's preoperative three-dimensional image data and intraoral scan data through computer software for virtual surgical planning. The structure of the implant guide body 100 replicates the planned three-dimensional position information of the implant and is configured to cover the patient's surgical area, including the affected tooth and surrounding healthy teeth, to provide initial retention and support.

[0020] The guide plate support device 200, located at the patient's gum line, is used to fix the implant guide plate body 100 in a predetermined position within the patient's mouth. It is typically designed as a base structure that conforms to the alveolar ridge crest or mucosal morphology. The design of the guide plate support device 200 ensures that the implant guide plate body 100 will not undergo unexpected displacement during the entire surgical procedure, providing a basic guarantee for subsequent operations.

[0021] The guide rail plate 300, mounted on the guide plate support device 200, serves as an independent reinforcing beam spanning diagonally in front of the surgical area. The guide rail plate 300 has a guide rail groove 310 extending in a specific direction. The trajectory of this guide rail groove 310 is set according to the optimal implantation path or instrument entry / exit path determined preoperatively. The function of the guide rail groove 310 is to cooperate with the outer end of the press-fit guide ring 400, achieving guidance and restriction of the instrument through physical constraints.

[0022] The planting guide plate body 100 has two channels, including a sliding operation channel 500 for guiding the instrument and an auxiliary positioning channel 600 arranged in parallel with the sliding operation channel 500.

[0023] The sliding operating channel 500 is the main operating channel for surgical instruments, such as pioneer drills, reamers, and implant placement devices. The sliding operating channel 500 has a certain length and extension, allowing instruments to slide within a certain range to adapt to the depth changes in preparation from the extraction socket to the implant socket. Simultaneously, the sliding operating channel 500 exposes critical areas requiring surgery, such as the periapical region of the extraction socket or the roots of adjacent teeth, providing the surgeon with an essential observation window and operating space.

[0024] To accommodate the different surgical needs of the anterior and posterior aesthetic zones, the 500 sliding operating channel is specifically divided into two types: First guide channel 510: Used in the anterior aesthetic zone. This channel has a small diameter and extremely high precision, and is configured as a strictly guiding instrument for implant surgery. Because the anterior zone has extremely high requirements for the protection of the labial bone plate, the first guide channel 510 precisely limits the angle of the drill bit, forcibly controlling the three-dimensional position of the implant in the aesthetic zone, effectively preventing the drill bit from deviating to the labial side and causing bone plate perforation, and ensuring the long-term aesthetic effect after implantation.

[0025] Second guide channel 520: Used in the posterior region. The posterior region often involves maxillary sinus floor elevation, therefore the width of the second guide channel 520 is designed to be greater than the width of the first guide channel 510. The second guide channel 520 is configured to accommodate internal elevation tools (such as sinus roof ejectors). This design allows for complex immediate internal elevation operations of the posterior teeth within a predetermined range, ensuring smooth passage of the tool while limiting excessive deviation through the channel walls, thus balancing operational flexibility and safety.

[0026] The auxiliary positioning channel 600 is arranged in parallel with the sliding operation channel 500. It is used to cooperate with the guide rail plate 300 and the press-fit guide ring 400 to achieve full-process support and guidance of the surgical instruments.

[0027] The press-fit guide ring 400 supports surgical instruments and forms a multi-point stable connection structure with the guide rail groove 310 and the auxiliary positioning channel 600. Each surgical instrument corresponds to 1-2 press-fit guide rings 400. The press-fit guide ring 400 is used in conjunction with the surgical instrument; changing the surgical instrument requires replacing the corresponding press-fit guide ring 400. The press-fit guide ring 400 includes the following key components: A sliding post 410 is located at the outer end of the press-fit guide ring 400 (i.e., on the side near the guide rail plate 300). The sliding post 410 is designed to embed into the guide rail groove 310 on the guide rail plate 300. Through the sliding engagement between the sliding post 410 and the guide rail groove 310, rigid guidance of the outer end of the press-fit guide ring 400 is achieved, which is equivalent to adding an additional external fulcrum to the instrument, greatly reducing the swaying of the instrument under long lever arms.

[0028] The stabilizing sleeve 420 is located inside the press-fit guide ring 400, and its position corresponds to the auxiliary positioning channel 600 on the implantation guide plate body 100. The stabilizing sleeve 420 is embedded in the auxiliary positioning channel 600. Through the cooperation of the stabilizing sleeve 420 and the auxiliary positioning channel 600, auxiliary guidance and positioning of the inner end of the press-fit guide ring 400 (i.e., the end near the surgical operation) are achieved.

[0029] Ring 430: Located above the sliding operating channel 500, it is the core component that directly contacts the surgical instruments. The ring 430 has extremely high internal bore precision, forming a tight tolerance fit with the matching surgical drill or implant adapter. Through the ring 430, axial support and depth guidance of the surgical instruments are achieved, ensuring that the instruments enter the alveolar bone strictly according to the predetermined path.

[0030] A robust multi-point support system is constructed through a dual constraint structure consisting of the guide rail plate 300, the sliding column 410, the auxiliary positioning channel 600, and the stabilizing sleeve 420. The sliding column 410 provides rigid guidance externally, effectively counteracting the leverage effect and lateral force generated by the long lever arm of the instrument; the stabilizing sleeve 420 provides internal auxiliary positioning, preventing the guide ring from rotating. This design improves stability during surgery and solves the problem of implantation deviation caused by instrument wobbling in traditional guide plates.

[0031] For the anterior aesthetic zone, the first guide channel 510 is used to forcibly limit the drill bit angle, effectively protecting the labial bone plate and ensuring aesthetic results. For the posterior zone, the wide-diameter second guide channel 520 is used, which not only meets the operating space requirements of the internal lifting tool but also retains boundary constraints to prevent excessive displacement. The zonal design allows the same guide plate system to flexibly handle the complex surgical requirements of different areas.

[0032] The guide plate support device 200 includes: a support plate body 210 and several blocks 220.

[0033] The support plate body 210 is the basic component of the guide plate support device 200. It is configured to be tightly installed at the patient's gums. The support plate body 210 is designed according to the digital model of the patient's surgical area and has a curved surface that closely matches the gingival morphology to ensure good initial stability when worn in the mouth and to prevent loosening or displacement during the operation.

[0034] Both the platform 220 and the guide rail plate 300 are mounted on the support plate body 210. The platform 220 has an installation groove 221. The installation groove 221 is preferably a rectangular groove, a dovetail groove, or a groove with a specific lateral limiting shape. The groove wall of the installation groove 221 has a through threaded hole, which is used for subsequent mating with fasteners.

[0035] On the planting guide plate body 100, a column 110 is provided at the position corresponding to the platform 220. The column 110 serves as a connecting extension of the planting guide plate body 100, and a mounting insert 120 is fixedly connected to its end. The outer contour shape of the mounting insert 120 is adapted to the inner cavity shape of the mounting groove 221. For example, when the mounting groove 221 is a dovetail groove, the mounting insert 120 is a dovetail protrusion that matches it. On the mounting insert 120, at the position corresponding to the threaded hole in the groove wall of the mounting groove 221, a through threaded hole or a smooth hole is also provided.

[0036] During surgical preparation or assembly, the implantation guide plate body 100 is placed over the guide plate support device 200. At this time, the column 110 is aligned with the platform 220, allowing the mounting insert 120 at the end to accurately extend into the mounting groove 221. Due to the matching shapes, the mounting insert 120 achieves initial positioning and limitation after insertion, preventing the implantation guide plate body 100 from sliding freely on the horizontal plane. Subsequently, bolts (or screws) are inserted into the threaded holes in the wall of the mounting groove 221 and tightened into the threaded holes of the mounting insert 120, thereby rigidly locking the mounting groove 221 and the mounting insert 120, completing the stable connection between the implantation guide plate body 100 and the guide plate support device 200.

[0037] An elongated guide strip 610 is provided along the extension direction of the auxiliary positioning channel 600. The stabilizing sleeve 420 is a U-shaped piece with a downward opening, which can be precisely snapped onto the elongated guide strip 610 within the auxiliary positioning channel 600. The surface of the elongated guide strip 610 is a curved convex surface, and the stabilizing sleeve 420 has a curved concave surface that matches the curved convex surface. When the press-fit guide ring 400 is installed in place, the U-shaped opening of the stabilizing sleeve 420 fits onto the elongated guide strip 610 from above, so that the curved concave surface on the stabilizing sleeve 420 and the curved convex surface on the elongated guide strip 610 fit tightly together.

[0038] The dual-channel guide plate system also includes: a first limiting structure 700, which is disposed on the surgical instrument; and a second limiting structure 431 disposed on the annular body 430, wherein the first limiting structure 700 can be engaged with the second limiting structure 431 to limit the movement stroke of the surgical instrument.

[0039] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
