Description

Technical Field

[0001] The utility model relates to the field of oral animal experiments, and particularly relates to a mouse mandibular anterior guidance invisible orthodontic appliance. Background Art

[0002] The concept of anterior guidance was first proposed by Broderson in 1978, which refers to the contact relationship between the upper and lower anterior teeth in the functional movements of the mandible in all directions. Anterior guidance plays a major guiding role in the anterior protrusion and lateral movement of the mandible. When the mandible moves, anterior guidance makes the posterior teeth disengage from occlusion, reducing abnormal mandibular movements caused by posterior tooth interference. It is an important factor in maintaining the health of the stomatognathic system.

[0003] When studying anterior guidance movement, an anterior guidance animal model of mice is often established, and based on this, the change effect and degree of anterior guidance on the stomatognathic system of mice are explored, providing a theoretical basis for the fields of restoration and orthodontic treatment. In previous operation methods, metal materials or resin materials are often used to make anterior guidance devices or modify the teeth of mice. This method often has high requirements for operators and is difficult to adjust in the later stage. Summary of the Utility Model

[0004] In order to solve the problems in the background art, the utility model proposes a mouse mandibular anterior guidance invisible orthodontic appliance. The device is formed by a transparent dental appliance, realizing the anterior guidance function of the mouse mandible and enabling the vertical and anteroposterior positioning of the mouse mandible.

[0005] The utility model is realized as follows:

[0006] The utility model includes a transparent dental appliance covering the upper jaw of a mouse. Two cavity structures are successively arranged on the transparent dental appliance along the anteroposterior direction of the dental arch. The two cavity structures respectively wrap and accommodate the upper anterior teeth and upper posterior teeth of the mouse.

[0007] The two cavity structures are respectively a first cavity structure arranged on the anterior side of the dental arch and a second cavity structure arranged on the posterior side of the dental arch. The first cavity structure is used to wrap and accommodate the upper anterior teeth of the mouse and is provided with a occlusal pad structure, and the second cavity structure is used to wrap and accommodate the upper posterior teeth of the mouse.

[0008] The transparent dental appliance of this orthodontic appliance covers the upper jaw part of the mouse, and at the same time, an occlusal pad structure is designed at the part of the transparent dental appliance of the upper anterior teeth of the mouse.

[0009] The two cavity structures are arranged on the top surface of the transparent dental appliance, so that the top surface of the transparent dental appliance contacts and wraps the upper jaw of the mouse.

[0010] The first cavity structure is mainly composed of two sub-cavities arranged adjacent to and communicating with each other along the front-back direction of the dental arch. The bottom surface of the posterior sub-cavity located at the posterior side of the dental arch is set as an inclined surface that slopes upward from the back to the front, so that a protrusion is formed within the first cavity structure at the junction between the two sub-cavities.

[0011] The overall shape of the first cavity structure is trapezoidal, and a concave corner space is formed between the outer bottom surfaces of the two sub-cavities. The corner space is used for the positioning and accommodation of the anterior teeth of the mouse mandible.

[0012] The outer bottom surface of the posterior sub-cavity located at the posterior side of the dental arch forms a jaw pad inclined surface for guiding and positioning during the occlusion of the anterior teeth of the mouse mandible.

[0013] The outer bottom surface of the anterior sub-cavity located at the anterior side of the dental arch is set as a plane, and the height of the plane is lower than the highest point height of the jaw pad inclined surface.

[0014] The cavity structure is wrapped around the upper teeth of the mouse by filling with a light-curing resin material.

[0015] The bottom end of the first cavity structure is lower than the bottom end of the second cavity structure.

[0016] The present utility model is located on the upper jaw of the mouse and is covered by a transparent dental appliance. It includes a housing for accommodating the anterior teeth and a posterior jaw pad for controlling the mandible of the mouse. The invisible orthodontic appliance is fixed to the upper jaw of the mouse, which can effectively control the anterior-posterior and vertical positions of the mouse mandible. This device is integrally formed by a bracketless invisible orthodontic appliance, and the height and leading position of the occlusion can be changed through digital design. Compared with other traditional leading devices, it can achieve a more personalized structural design and simpler operation.

[0017] Advantages of the present utility model:

[0018] The present utility model first makes and realizes a leading device for mice through an invisible orthodontic appliance, making the clinical experiment operation simpler.

[0019] By designing a cavity structure for accommodating the anterior teeth and posterior teeth of the mouse upper jaw, the present utility model can fix the device well on the mouse upper jaw, avoiding the situation of device detachment during the clinical trial process.

[0020] By designing a transparent jaw pad structure, the present utility model can accurately position the mouse mandible at the target position under the guidance of the transparent jaw pad structure, and thus effectively control the movement of the mouse mandible. Description of the Drawings

[0027] In order to make the purpose, technical solutions, and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] As Figure 1 shown is the structure of the upper teeth of the mouse, where the part 101 is the upper incisor of the mouse, and the part 102 is the upper posterior tooth of the mouse.

[0029] As Figure 2 shown, the invisible orthodontic appliance designed by the present utility model includes a transparent dental appliance that wraps and covers the upper jaw of the mouse. The front part of the transparent dental appliance contains a structure for accommodating the upper incisors of the mouse, and the rear part of the transparent dental appliance is designed with a transparent occlusal pad structure. The transparent dental appliance is sequentially provided with two cavity structures along the anteroposterior direction of the dental arch. The two cavity structures respectively wrap and accommodate the upper incisors and upper posterior teeth of the mouse, and the two cavity structures are respectively wrapped and fixed on the upper jaw of the mouse and contacted by the lower jaw of the mouse.

[0030] The two cavity structures are respectively the first cavity structure 201 arranged on the front side of the dental arch and the second cavity structure 202 arranged on the rear side of the dental arch. Among them, the first cavity structure 201 is used to wrap and accommodate the upper incisors 101 of the mouse and is provided with an occlusal pad structure, and the second cavity structure 202 is used to wrap and accommodate the upper posterior teeth 102 of the mouse. The two cavity structures are both opened on the top surface of the transparent dental appliance, so that the top surface of the transparent dental appliance contacts and wraps the upper jaw of the mouse.

[0031] In order to achieve good fixation of the device on the upper teeth of the mouse, the transparent dental appliance should first be designed with sufficient space for accommodating the upper incisors 101 of the mouse as the first cavity structure 201 in the part of the upper incisors of the mouse, and the first cavity structure 201 is fixed on the upper incisors 101 of the mouse by filling and bonding with a light-curing resin material.

[0032] In specific implementation, if it is necessary to achieve good retention of the overall structure, all transparent dental appliances can further cover the posterior tooth area of the mouse's maxilla.

[0033] Furthermore, the posterior tooth area is designed with sufficient space to accommodate the posterior teeth of the mouse's maxilla as the second cavity structure 202. Similarly, by filling and bonding with a light-curing resin material, the second cavity structure 202 is fixed on the posterior teeth 102 of the mouse's maxilla.

[0034] As Figure 2 shown in the top-view structure diagram of the device, 201 in the figure is the cavity structure that wraps and accommodates the anterior teeth of the mouse, and 202 is the cavity structure that wraps and accommodates the posterior teeth of the mouse's maxilla.

[0035] As Figure 3 shown, the first cavity structure 201 is mainly composed of two sub-cavities arranged adjacent to and communicating with each other along the anteroposterior direction of the dental arch. The bottom surface of the anterior sub-cavity located on the anterior side of the dental arch can be set as a plane, and the bottom surface of the posterior sub-cavity located on the posterior side of the dental arch is set as an inclined plane that slopes upward from the back to the front, so that a protrusion is formed at the junction between the two sub-cavities within the first cavity structure 201.

[0036] As Figure 4 shown, the first cavity structure 201 is in an overall trapezoidal structure, and the height of the part close to the anterior teeth is lower than the height of the part close to the posterior teeth, that is, a front-high and back-low inclined plane structure is formed in the posterior sub-cavity. At the same time, there is a significant height difference between the front part of the inclined plane structure and the rear part of the anterior sub-cavity structure in the front part of the transparent dental appliance, forming an obvious angular connection, guiding the anterior teeth 401 of the mouse's mandible to terminate at the angular position during occlusion, realizing the position positioning and limitation of the mouse's mandibular position. A concave angular space is formed between the outer bottom surfaces of the two sub-cavities, and the angular space is used for the positioning and accommodation of the anterior teeth of the mouse's mandible.

[0037] In this way, the outer bottom surface of the posterior sub-cavity located on the posterior side of the dental arch forms a jaw pad inclined plane 301 for guiding and positioning during the occlusion of the anterior teeth 401 of the mouse's mandible. The anterior sub-cavity located on the anterior side of the dental arch is used for the accommodation and wrapping of the anterior teeth 101 of the mouse's maxilla.

[0038] In order to achieve stable occlusion of the mouse's mandibular position by the device, from the perspective of the occlusal surface, the width of the jaw pad structure of the first cavity structure 201 is greater than the width of the anterior teeth 101 of the mouse's maxilla, and its specific value is between 3 mm and 8 mm.

[0039] As Figure 3The side structure schematic diagram of the device is shown. Here, 301 shown is the transparent jaw pad inclined plane of the transparent dental appliance, which extends from the front of the anterior teeth of the mouse backward and downward to the upper jaw area of the mouse. When the transparent dental appliance is occluded, the height of the front part is higher than that of the rear part. 302 shown is a plane, whose height is lower than the highest point of the jaw pad inclined plane 301, which can prevent premature contact during occlusion. When the mouse wears this appliance, the anterior teeth of the mouse mandible first contact the lowest point of the jaw pad inclined plane 301 during occlusion, and through the guidance of the inclined plane of the jaw pad inclined plane 301, they finally move and are positioned at the fold angle where the jaw pad inclined plane 301 and the plane 302 meet.

[0040] The outer bottom surface of the front sub-cavity located at the front side of the dental arch is set as the plane 302, and when the transparent dental appliance is occluded and wrapped around the anterior teeth of the mouse, the height of the plane 302 is lower than the highest point height of the jaw pad inclined plane 301, that is, the bottom end of the front sub-cavity located at the front side of the dental arch is higher than the bottom end of the rear sub-cavity located at the rear side of the dental arch.

[0041] In order to accurately limit the position of the mouse mandible by this device and avoid premature contact during occlusion of the anterior teeth of the mouse, when the transparent dental appliance is occluded and wrapped around the anterior teeth of the mouse, the plane 302 structure designed in the first cavity structure 201 of the front part of the transparent dental appliance has a height higher than the lowest height of the transparent jaw pad structure.

[0042] In specific implementation, both cavity structures are wrapped around the upper teeth of the mouse by filling with a light-curing resin material.

[0043] As Figure 5 shown is the 3D printed dental film model used to make this device. The transparent dental appliance can be obtained by 3D printing a dental film and then through a hot pressing film forming process and a cutting process.

[0044] After specific implementation and production, as Figure 4 shown, it is a schematic diagram after the appliance is fixed on the teeth of the mouse. The transparent dental appliance structure reserves cavity structures on both the anterior upper teeth 101 and the posterior upper teeth 102 of the mouse. After being worn on the upper teeth of the mouse, there is a gap space between the transparent dental appliance and the upper teeth of the mouse, and this gap space is used to fill with a light-curing resin material so that this device can be fixed on the teeth of the mouse.
