Description

Technical Field

[0001] This utility model relates to the technical field of dental implant teaching tools, and more specifically, it relates to a physiological and anatomical model for teaching based on edentulous jaws with severe bone loss. Background Technology

[0002] With the development of oral medicine and the widespread application of dental implant technology, the demand for dentist training is increasing. Especially in cases of severe bone loss and edentulism, the implant surgery is more challenging due to insufficient bone volume and complex bone structure, placing higher demands on the dentist's surgical skills and treatment planning abilities. However, during dentist training, real patient case resources are limited, and operational errors can have adverse effects on patients. Therefore, using physiological and anatomical models for teaching is particularly important for practice and instruction.

[0003] Existing teaching models are typically based on standard jawbone anatomy and lack realistic representation of edentulous jaws with severe bone loss. These models often fail to effectively simulate the anatomical features of severe bone loss, such as reduced bone density, insufficient bone height and width, hindering surgeons' ability to adequately address real-world challenges during training. Furthermore, traditional teaching models are usually limited to static demonstrations, lacking flexible design support for different surgical approaches and failing to provide diverse implant simulation exercises, such as designing implant placements at different locations and angles.

[0004] To address these issues, there is an urgent need for a teaching physiological and anatomical model that can highly reproduce the anatomical features of severely edentulous jaws with bone loss and support the design and practice of various implant surgery procedures. Utility Model Content

[0005] The purpose of this invention is to provide a teaching physiological and anatomical model based on severely edentulous jaws by precisely setting the implantation hole positions on the model to meet different surgical needs. This model can not only improve doctors' practical skills in complex surgical scenarios, but also provide a more scientific and effective teaching tool for medical education.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A teaching physiological and anatomical model based on a severely edentulous jaw with bone loss includes a main body model simulating the physiological and anatomical structure of the maxilla. The main body model has multiple pre-fabricated holes, the layout and direction of which include: left and right pterygoid holes, left single zygomatic hole, right double zygomatic hole, right maxillary sinus anterior tilting hole, left sinus hole, left and right nasal turbinate crest holes, left and right anterior nasal spine mesial tilting holes, incisor canal hole and anterior nasal spine hole.

[0008] Each of the pre-drilled holes has a guide channel for instrument movement, allowing operators to practice using instruments within the guide channel to meet the needs of different dental implant surgeries.

[0009] The present invention is further configured such that a positioning component is provided on one side of the model body to facilitate clamping the model body.

[0010] The present invention is further configured such that: the surface of the model body is provided with markings for identifying different physiological and anatomical regions and the positions of pre-fabricated holes, and the markings are color-coded to distinguish the function of the holes.

[0011] The present invention is further configured such that: the surface of the model body is provided with a removable covering layer for simulating soft tissue structure.

[0012] Compared with the shortcomings of the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention, by precisely setting various holes on the main body of the model, including left and right wing holes, zygomatic holes, maxillary sinus holes, nasal turbinate crest holes, and anterior nasal spinous foramen, can comprehensively simulate implant surgery in cases of severe bone loss and edentulous jaws, covering complex case teaching scenarios.

[0017] Reference Figures 1 to 3 The embodiments of this utility model will be further described.

[0018] This embodiment specifically includes a model body that simulates the physiological and anatomical structure of the maxilla. The model body adopts a biomimetic anatomical design and is precisely manufactured based on the actual anatomical characteristics of a severely bone-deficient edentulous jaw, including but not limited to features such as insufficient bone height, reduced bone width, and enlarged maxillary sinus.

[0019] The main body of the model has multiple pre-made holes. The layout and direction of the pre-made holes include: left and right wing holes 1, left single zygomatic hole, right double zygomatic hole, right maxillary sinus anterior tilting hole, left sinus hole, left and right turbinate crest holes 3, left and right anterior nasal spine mesial tilting holes 4, incisor canal hole 2 and anterior nasal spine hole.

[0020] The diameter, depth, and tilt angle of the pre-drilled holes are designed according to the anatomical characteristics of edentulous jaws with severe bone loss. Each of the pre-drilled holes has a guide channel for instrument movement, allowing operators to practice using instruments within the guide channel to meet the needs of different dental implant surgeries.

[0021] A positioning component 5 is provided on one side of the model body to facilitate clamping the model body. The positioning component 5 is fixed to the teaching operation table by an adjustable clamping mechanism to ensure that the model remains stable during the teaching process.

[0022] The surface of the model body is marked with markers to identify different physiological and anatomical regions and the locations of pre-drilled holes. These markers are color-coded to distinguish the function of each hole. The markers are designed with a wear-resistant coating or embedded color bars, ensuring they remain clearly visible even after repeated practice.

[0023] The model's main body has a removable cover layer to simulate soft tissue structures. The cover layer is made of a composite of imitation skin material and elastic gel material, possessing elasticity and flexibility, and can reproduce the traction and cutting characteristics of soft tissue during surgery.

[0024] The model supports simulation of various surgical pathways, such as zygomatic bone implantation, nasal turbinate crest implantation, and maxillary sinus tilt implantation. Through hole positioning guidance, the surgical instruments can be stably advanced along the target path, meeting the teaching needs of complex implantation techniques.
