Description

Technical Field

[0001] This utility model relates to a guide plate for simultaneous implantation of cyst fluid extraction and internal lifting, belonging to the field of oral surgery technology. Background Technology

[0002] After the loss of maxillary posterior teeth, the floor of the maxillary sinus will descend to the original location of the missing tooth's root. At this point, implant placement could potentially penetrate the maxillary sinus wall. To accommodate the implant, a maxillary sinus lift is necessary. This involves transplanting synthetic bone substitutes to elevate the sinus to its original position, ensuring the implant is properly positioned within the maxilla.

[0003] There are two types of maxillary sinus lift surgery: external maxillary sinus lift and internal maxillary sinus lift. Internal maxillary sinus lift involves lifting the maxillary sinus floor through the alveolar ridge. This method uses impact or water pressure to lift a portion of the bone or mucosa at the maxillary sinus floor into the sinus cavity through the implant placement hole. There are no additional incisions, resulting in minimal surgical trauma. This surgery can achieve the desired lift height for patients requiring implant placement.

[0004] During maxillary sinus lift surgery, the maxillary sinus sac needs to be aspirated. However, determining the aspiration site and precisely controlling the fenestration location are challenging, increasing the risk of damage to the sinus floor membrane or surrounding tissues and raising the risk of postoperative complications. Maxillary sinus lift surgery also requires implant placement from the floor of the maxillary sinus. During implant placement, the position, angle, and depth of the implant are difficult to control, and implant misalignment can affect the final result.

[0005] Therefore, it is necessary to design a guide plate for simultaneous cyst fluid extraction and internal lifting to increase the precision, efficiency, and stability of maxillary sinus lift surgery. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a guide plate for simultaneous endoscopic sinus lift and implantation, which solves the problem of inaccurate window opening and implant placement during maxillary sinus lift surgery.

[0027] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] Example 1

[0029] like Figures 1-4 As shown, a guide plate for simultaneous cyst fluid extraction and internal removal during implantation includes...

[0030] Fixation device 1 and guide plate 2, wherein the fixation device 1 can be fixed to the patient's teeth, and the guide plate 2 is provided on one side of the fixation device 1.

[0031] In this embodiment, the fixation device 1 is installed at the patient's upper central incisors and lateral incisors, and the fixation device 1 is also provided with an extension rod 12. The extension rod 12 is located inside the patient's dentition, and one end of the extension rod 12 extends along the patient's missing molars and fits against the patient's dentition.

[0032] A guide plate 2 is provided on the extension rod 12, extending outward from the patient's dentition. The guide plate 2 passes through the location where the implant needs to be performed and extends outward from the patient's dentition. An implant positioning hole 22 is provided at the location of the missing teeth, i.e., the location where the implant needs to be performed. A fenestration guide opening 23 is provided on the outer side of the patient's dentition on the guide plate 2, which can guide the aspiration of maxillary sinus cyst fluid.

[0033] Reference Figure 1 , Figure 2 The structure of the fixation device 1 is consistent with the patient's dentition structure, allowing it to be fixed to the patient's dentition and providing stable support for capsule fluid extraction and implantation procedures. The fixation device 1 is positioned in the patient's upper incisor region, utilizing the stability of the dentition in this area to support the entire fixation device 1. The extension bar 12 extends from the inside of the fixation device 1, conforming to the molar region along the direction of the missing dentition, forming a stable extension structure to ensure that the guide plate covers the operating area.

[0034] The extension rod 12 serves as a supporting structure connecting the fixing device 1 and the guide plate 2, and extends into the patient's missing tooth area, providing a positioning base for the guide plate 2. The extension rod 12 conforms to the patient's dentition, avoiding errors caused by excessive distance or instability. The guide plate 2 is mounted on the extension rod 12 and can be fixed by the extension rod 12. In this embodiment, the guide plate 2 and the extension rod 12 are connected by tenon and mortise joints, and the guide plate 2 and the extension rod 12 are detachable.

[0035] Reference Figure 2 , Figure 3 , Figure 4 The extension rod 12 has two slots; the guide plate 2 has two protrusions 21 spaced at a certain distance. The protrusions 21 are cuboids, and their structure matches that of the slots on the extension rod 12. In this embodiment, the slots on the extension rod 12 can be connected and fixed to the protrusions on the guide plate 2, thus fixing the guide plate 2 to the extension rod 12.

[0036] The guide plate 2 extends to the outer side of the patient's missing tooth area and connects to the extension rod 12. Implant positioning holes 22 are provided in the patient's missing tooth area to precisely guide implant placement. The number of implant positioning holes 22 corresponds to the number of teeth requiring implantation. In this embodiment, there are two implant positioning holes 22, fixed at the bottom of the teeth requiring implantation. The implant positioning holes 22 are connected and fixed by support posts to increase overall strength and prevent deformation during surgery. A guide rod is provided in the middle of the support post 1, extending outwards and upwards a certain distance. A fenestration guide opening 23 is provided at the top of the guide rod. The fenestration guide opening 23 is located on the outer side of the patient's dentition, pointing to the location where the endothelial fluid needs to be extracted. In this embodiment, the fenestration guide opening 23 is a hollow cylinder, precisely guiding the fenestration operation for endothelial fluid extraction.

[0037] In this embodiment, for patients who need to undergo maxillary sinus cyst fluid aspiration and internal lifting, the patient's jawbone information is first obtained by CT scan, and the patient's dentition and soft tissue data are obtained by intraoral scanner. Fixation device 1 and guide plate 2 are then fabricated. The positions of the implant positioning hole 22 and the fenestration guide opening 23 of the guide plate 2 are determined by the patient's jawbone information and the patient's dentition and soft tissue data obtained by intraoral scanner. The location of maxillary sinus cyst fluid aspiration and implant placement are then located.

[0038] In this embodiment, the fixation device 1 is provided with an observation window 11 at the patient's incisor to facilitate intraoperative inspection of whether the device is in place and to observe the fixation status of the fixation device during the operation.

[0039] In this embodiment, the guide plate 2 is equipped with a positioning implantation hole 22 and a fenestration guide opening 23. This ensures that the specific location and range of the fenestration are clearly indicated during the operation, avoiding accidental damage to surrounding tissues due to inaccurate positioning. The hollow cylindrical design of the fenestration guide opening 23 limits the angle and depth of the fenestration tool, making the cyst fluid extraction more precise. This reduces the risk of sinus floor membrane tearing and maxillary sinus infection; improves the safety and precision of the operation; and lowers the incidence of postoperative complications.

[0040] The positioning holes 22 ensure immediate implantation after the intraoperative lifting procedure, and the number of positioning holes matches the patient's needs, guaranteeing that the implant placement does not deviate. When multiple implants are required, support columns are placed between the positioning holes 22 to enhance the stability of the guide plate 2, ensuring consistency among the multiple positioning holes 22 and preventing displacement or deformation due to intraoperative stress. By setting the positioning holes 22, the risk of implant displacement is reduced, and the treatment cycle is shortened.

[0041] The fixation device 1 and the guide plate 2 are connected by mortise and tenon joints to ensure the stability of the device during surgery and to facilitate disassembly and adjustment of the guide plate 2 and fixation device 1. A positioning observation window 11 is provided on the fixation device 1, allowing the surgeon to check in real time during surgery whether the device is securely in place, ensuring accurate operation.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
