The terms "first", "second" and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a communication between the internal parts of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to the specific circumstances.
[0029] Combine Figures 1-8 As shown, a detachable edentulous maxillary model includes a maxillary body 10, a palatal wrinkle piece 20 and a maxillary tuberosity piece 30; the maxillary body 10 includes an inner half 11 and an outer half 12, the outer half 12 is clamped on the circumference of the inner half 11, and forms a detachable connection with the inner half 11; a plug body 21 is provided at the bottom of the palatal wrinkle piece 20, the top of the plug body 21 is fixedly connected to the bottom of the palatal wrinkle piece 20, and its bottom is embedded in the top of the inner half 11; a connecting piece 31 is provided between the maxillary tuberosity piece 30 and the maxillary body 10, one end of the connecting piece 31 is fixedly connected to the top of the maxillary tuberosity piece 30, and its bottom is screwed to the bottom of the inner half 11.
[0030] In the above scheme, the maxillary body 10 is composed of an inner half 11 and an outer half 12, which are connected and detachably held together by buckles and bolts to form a complete maxillary structure. The setting of the bolt body 21 not only serves as a medium for connecting the palatal wrinkle piece 20 and the inner half 11, but also ensures the stable connection between the palatal wrinkle piece 20 and the inner half 11. The bottom of the bolt body 21 is embedded in a preset hole or groove on the top of the inner half 11, and a stable connection between the palatal wrinkle piece 20 and the inner half 11 is achieved through interference friction or buckle. The maxillary tuberosity piece 30 is fixedly connected to the inner half 11 through the connecting piece 31. The connecting piece 31 in the present application is a stud, and the purpose of such a setting is that one end of the stud is fixedly connected to the bottom of the maxillary tuberosity piece 30, which can allow the maxillary tuberosity piece 30 to be adjusted up and down or disassembled in the inner half 11.
[0031] In this application, teachers can display different parts of the maxilla as needed, such as displaying the palatal rugae or tuberosities separately, helping students better understand the complex structure of the maxilla. Students or trainers can disassemble and assemble the model by hand, enhancing their practical skills and deepening their understanding of oral anatomy. During doctor-patient communication, doctors can display the various parts of the model and explain the structure and function of the maxillary tissue in detail to patients, raising their awareness of oral health issues. The detachable design allows doctors to simulate different oral conditions, such as missing teeth and maxillary bone lesions, for more intuitive explanation of treatment plans.
[0032] The plug body 21 includes a main trunk 211 and a branch trunk 212. The top of the main trunk 211 is integrally connected to the middle of the bottom surface of the palatal wrinkle component 20. The branch trunk 212 is fixedly arranged on the peripheral side of the main trunk 211. The top of the branch trunk 212 is fixedly connected and engaged with the bottom surface of the palatal wrinkle component 20, and the bottom of the branch trunk 212 is embedded in the top of the inner half body 11.
[0033] In the above embodiment, the main stem 211 serves as the primary component of the plug body 21. Its top is integrally connected to the middle portion of the bottom surface of the palatal wrinkle member 20, ensuring vertical stability of the palatal wrinkle member 20. The branch stem 212 is fixedly disposed around the periphery of the main stem 211, providing additional support for the main stem 211 and the palatal wrinkle member 20. The top of the branch stem 212 is fixedly connected to the bottom surface of the palatal wrinkle member 20, enhancing the connection strength between the palatal wrinkle member 20 and the plug body 21. The bottom of the branch stem 212 is embedded in the top of the inner half 11, not only providing horizontal stability to the palatal wrinkle member 20 and the inner half 11, but also allowing for a certain degree of adjustment in the position or angle of the palatal wrinkle member 20.
[0034] The arrangement of the main stem 211 and branches 212 in this application provides multiple fixing points between the palatal wrinkle member 20 and the inner half-body 11, thereby enhancing the stability of the connection between the palatal wrinkle member 20 and the maxillary body 10. Furthermore, the design of the branches 212 allows for a certain degree of adjustment in the position and angle of the palatal wrinkle member 20 to accommodate different teaching or demonstration needs, enabling the model to more accurately simulate the shape and position of the palatal wrinkles in a real oral cavity.
[0035] A groove 111 is provided on the top of the inner half body 11 , and the groove wall of the groove 111 is slidably connected to the bottom circumference of the branch 212 .
[0036] In the above scheme, the shape and size of the groove 111 match the bottom of the branch 212 so that the branch 212 can slide in and out smoothly. And the groove wall of the groove 111 has a certain smoothness to reduce the friction resistance of the branch 212 during the sliding process, ensuring that the branch 212 can move easily along the groove wall. When the palatal wrinkle piece 20 needs to be installed on the inner half body 11, the user can align the bottom of the branch 212 with the entrance of the groove 111 and push the branch 212 to slide along the groove wall to the desired position. The sliding connection design makes the installation and removal of the palatal wrinkle piece 20 simple and quick, without the need for complicated operating steps or tools.
[0037] The outer half 12 includes a first half 121 and a second half 122 . The first half 121 and the second half 122 are C-shaped and are connected to each other.
[0038] In the above embodiment, during the plugging process, the C-shaped opening of the first half 121 is aligned with the corresponding portion of the second half 122. Then, by a certain external force or mechanical device, the first half 121 is pushed into the C-shaped opening of the second half 122 until the two are fully plugged together.
[0039] The C-shaped interlocking structure of the present invention makes the outer half 12 more stable overall, capable of withstanding greater external forces and pressures. The interlocking structure simplifies and expedits the assembly of the first half 121 and the second half 122, eliminating the need for complex steps or tools. This reduces assembly costs and time, and improves production efficiency. The C-shaped interlocking design allows the outer half 12 to adapt to various sizes and shapes.
[0040] An L-shaped limit pin 1211 is fixedly provided on the inner side of the first half body 121, and the top end surface of the horizontal section of the limit pin 1211 is flush with the top end surface of the first half body 121; a limit groove 1221 adapted to the limit pin 1211 is provided on the inner side of the second half body 122, and the circumferential surface of the limit pin 1211 is slidably connected to the groove wall of the limit groove 1221.
[0041] In the above embodiment, during the insertion process, the first and second halves 121, 122 gradually approach each other, with the horizontal section of the stop pin 1211 first contacting the entrance of the stop slot 1221. As the insertion process continues, the stop pin 1211 slides along the walls of the stop slot 1221 until it is fully inserted into the stop slot 1221. The vertical section of the stop pin 1211 acts as a stopper, preventing relative movement between the first and second halves 121, 122 when subjected to external forces.
[0042] The top of the inner half body 11 is provided with a tie member 40 and a ligament member 50 , which are in an I-shaped structure. The periphery of the tie member 40 and the ligament member 50 are fixedly connected to the junction of the inner half body 11 , the first half body 121 and the second half body 122 .
[0043] It should be noted that the tie member 40 in this application comprises the lip frenulum and cheek frenulum, and the ligament member 50 is the pterygomandibular ligament. The horizontal sections of the tie member 40 and ligament member 50 are vertically inserted at the junction of the inner half 11, the first half 121, and the second half 122, tightly connecting them. The I-shaped structure provides strong vertical load-bearing capacity and stability.
[0044] A mounting groove 22 is recessed at the junction of the first half body 121, the second half body 122 and the inner half body 11, the notch of the mounting groove 22 faces upward, and a positioning pin 221 of a plate-like structure is fixedly provided in the groove wall of the mounting groove 22. A positioning groove 60 is recessed at the bottom of the tie member 40 and the ligament member 50, and the groove wall of the positioning groove 60 is slidably connected to the circumference of the positioning pin 221.
[0045] In the above solution, the sliding connection between the positioning slot 60 and the positioning pin 221 ensures precise positioning of the tie member 40 and the ligament member 50 during installation, preventing structural instability or performance degradation due to improper installation. The tie member 40 and the ligament member 50 are compact in structure, and their plug-in design makes installation simple and quick, eliminating the need for complex steps or tools. For removal, simply pull the tie member 40 and the ligament member 50 away from the bottom of the inner half 11.
[0046] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.
[0047] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some or all of the technical features therein can be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present application.
