Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a device for simulating implant perforation in edentulous jaws. Background Technology

[0002] Dental implant surgery is an important restorative technique in dentistry, used to replace missing teeth and restore chewing function and aesthetics. Edentulous jaw implant surgery, due to its complex anatomical structure (such as alveolar bone, mucosa, and nerve canal), high precision requirements, and significant risks (such as nerve damage and infection), places extremely high demands on the surgeon's skill and experience. Currently, dentist training primarily relies on clinical practice, animal experiments, and extracted tooth models. However, these methods have several drawbacks: clinical practice suffers from limited resources, high risks, high costs, and a lack of standardization; animal experiments are hampered by significant anatomical variations, ethical constraints, and resource shortages; and extracted tooth models lack the realism of the overall oral environment, offer insufficient dynamic interactivity, provide limited training scenarios, and have limited and difficult-to-update resources.

[0003] Current technologies cannot simultaneously meet the core requirements of morphological realism, biomechanical feedback accuracy, and real-time error alerts in edentulous implant surgery training while maintaining low cost and high accessibility. Therefore, a reliable and accurate training device is urgently needed to improve training efficiency and safety. Summary of the Invention

[0004] The present invention provides a simulated implant perforation device for edentulous jaws and its preparation and use method. Combining a physical model with intelligent sensing technology, it accurately simulates surgical risk points through physical interaction and a real-time alarm mechanism, thereby improving the training efficiency and safety of implant surgery.

[0005] To achieve the above objectives, the technical solution of this utility model includes: An edentulous jaw implant perforation device includes a mandibular model with a hollow section containing bone blocks to simulate the alveolar bone in the implantation area. A pressure sensor is installed at the bottom of the hollow section to simulate the inferior alveolar nerve canal. The pressure sensor is used to trigger an alarm when the implantation instrument enters the sensing area of ​​the pressure sensor.

[0006] Furthermore, the bone block is detachably placed within the hollow portion so that the bone block is replaceable, and the area to be implanted is the area where the pre-designated dental implant is located.

[0007] Furthermore, the hollow portion is an upward-facing arc-shaped groove that extends along the dental arch of the jawbone model. The pressure sensor is mounted on the bottom surface of the hollow portion and located at its center in the width direction. The opening of the hollow portion is used to place the bone block.

[0008] Furthermore, the width of the hollowed-out portion is 8mm and the depth is 12mm.

[0009] Furthermore, there are two pressure sensors, which are respectively set on the left and right sides of the jawbone model and correspond to the location of the inferior pressure groove nerve canal; each pressure sensor is electrically connected to an indicator light for alarm purposes; a wire hole is formed on the side wall of the jawbone model, which corresponds to the mental foramen of the jawbone, and the wire hole is used to pass through the electrical connection wire of the pressure sensor, so that the indicator light is set outside the jawbone model.

[0010] Furthermore, the pressure sensor is a vibration switch.

[0011] The beneficial effects of this utility model include: This invention highly replicates the anatomical structure of a real edentulous human jaw, providing operators with a training platform that closely resembles a real surgical environment, significantly enhancing the realism of training. The bone material and pressure sensors embedded in the device provide real-time tactile and force feedback, helping doctors master surgical techniques more accurately in simulated surgery and effectively improving surgical skills. Furthermore, because the bone material in the device can be repeatedly replaced, training costs are significantly reduced, while providing a standardized platform for dental implant surgery training. This invention is not only suitable for training clinicians but can also serve as a teaching tool and research platform, promoting oral medicine education and technological innovation.

[0012] This edentulous jaw implant perforation device highly replicates the real edentulous jaw implant surgery environment, enabling repeated training, reducing training costs, enhancing the realism of training, and providing a standardized training platform. This addresses the problems of resource shortage, high cost, and insufficient realism in existing dental implant surgery training, which is conducive to improving doctors' skills, reducing surgical risks, and promoting the development of dental implant surgery technology.

[0018] The components include: 1 jawbone model, 11 hollowed-out sections, 12 threading holes, 2 bone blocks, and 30 indicator lights. Detailed Implementation

[0019] The present invention will now be described in detail with reference to the views. The listed embodiments will enable those skilled in the art to better understand the present invention, but will not limit the present invention in any way.

[0020] like Figure 1 As shown, this utility model discloses a simulated implant perforation device for edentulous jaws, including a mandibular model 1. The mandibular model 1 has a hollowed-out portion 11, within which a bone block 2 is provided to simulate the alveolar bone of the implantation area. A pressure sensor is installed at the bottom of the hollowed-out portion 11 to simulate the inferior alveolar nerve canal. The pressure sensor is used to trigger an alarm when the implantation instrument enters the sensing area of ​​the pressure sensor. Only the indicator light 30 located outside the mandibular model 1 is shown in the figure. The pressure sensor is connected to the indicator light 30 via an electrical connection wire, and the indicator light 30 is connected to a power source, thereby causing the pressure sensor to trigger an alarm via the indicator light 30; that is, the indicator light illuminates as an alarm.

[0021] This invention highly replicates the anatomical structure of a real edentulous human jaw, providing operators with a training platform that closely resembles a real surgical environment, significantly enhancing the realism of training. The bone material and pressure sensors embedded in the device provide real-time tactile and force feedback, preventing the device from drilling into the inferior alveolar nerve canal. This helps surgeons master operational techniques more accurately in simulated surgery, effectively improving surgical skills. This invention is not only suitable for training clinicians but can also serve as a teaching tool and research platform, promoting oral medicine education and technological innovation.

[0022] Bone block 2 is detachably placed within the hollow portion 11, allowing for replacement and enabling the device to be reused for simulation operations by replacing bone block 2. The implantation area is the pre-defined region where the implant tooth will be located. For edentulous patients, this area comprises the original growth sites of multiple extracted teeth, extending along the dental arch. Its width and depth are slightly greater than the width and depth of normal teeth within the alveolar bone. This ensures that the simulation operations are performed on bone block 2 without damaging the dental model, facilitating reuse. To allow bone block 2 to be placed within the hollow portion 11, the width and depth of the hollow portion 11 should be greater than that of bone block 2. In this embodiment, the width of the hollow portion 11 is 8 mm, and its depth is 12 mm.

[0023] Thus, the hollow section 11 forms an upward-facing arc-shaped groove structure. The hollow section 11 extends along the dental arch direction of the jawbone model 1. The pressure sensor is installed on the bottom surface of the hollow section 11 and located at the center of its width direction. The opening of the hollow section 11 is used to place the bone block 2. In addition, the opening of the hollow section 11 faces upward, so that in addition to replacing the bone block through this opening, the operator can also use a drill or other implantation instrument to drill the bone block downward through the opening above the bone block 2, thereby reducing the opening of the hollow section 11.

[0024] In this embodiment, two pressure sensors are used, respectively positioned on the left and right sides of the jawbone model 1, corresponding to the location of the inferior fossa nerve canal. Each pressure sensor is electrically connected to an indicator light for alarm purposes, promptly alerting the operator to any operational errors. A threading hole 12 is formed on the side wall of the jawbone model 1, corresponding to the mental foramen of the jawbone. The threading hole 12 is used to thread the electrical connection wire of the pressure sensor, thus placing the indicator light outside the jawbone model 1 for easy observation by the operator. Furthermore, the pressure sensor is also connected to a power source via this electrical connection wire. Using two pressure sensors to simulate the inferior fossa nerve canals on both sides allows for reliable simulation for edentulous patients, regardless of which side of the mouth is implanted. Of course, in other embodiments, only one pressure sensor may be used, with its position on the left and right sides of the jawbone model adjusted according to simulation needs.

[0025] The pressure sensor uses a vibration switch, specifically a C06 sensitive ball spring SMD vibration sensor switch. This switch can detect vibration damage to the nerve canal in the pressure groove caused by excessive force during the implantation process, thus expanding the detection range and allowing damage to be detected before the drill bit contacts the pressure sensor. Of course, other types of sensors, such as contact pressure sensors, can also be used.

[0026] The edentulous jaw implant perforation device disclosed in the embodiments can be prepared using the following method, the steps of which include: S1. Create jawbone model 1 by printing jawbone model 1 using 3D printing technology; S2. Model assembly: Place the pressure sensor at the bottom of the hollow part 11 to simulate the inferior alveolar nerve canal, and place the bone block 2 above the pressure sensor to simulate the alveolar bone in the area to be implanted.

[0027] Specifically, step S1 includes: S11. Image processing: Using the medical image software Mimics, the oral CT images of edentulous patients are segmented, reconstructed, and visualized to generate a three-dimensional oral model of edentulous patients. This oral model only includes the skeletal model. S12. Model cutting and export: The generated oral model is cut into multiple planes in the medical imaging software Mimics, the lower tooth alveolar bone is hollowed out, the wire hole 12 for the electrical connection wire of the pressure sensor is left to pass through, and the hollow part 11 is set. Then it is exported in STL format. S13. 3D printing preparation: Import the STL file exported in step S12 into SOLIDWORKS software and set up relevant support structures based on the skeletal model. S14. Model printing: Use 3D printing technology to print a jawbone model.

[0028] The remaining undescribed parts are existing technology.

Any improvements or equivalent substitutions made based on the technical concept proposed by this utility model shall fall within the protection scope of this utility model.
