The utility model provides a device 1 is rescued in stealthy of no tooth face that closes, including medial surface 11, lateral surface 12, top surface 13, storage tank 14, wear hole 15 and connection face 16, medial surface 11 is the side that is located near the tongue, lateral surface 12 is the side that is close to the cheek, medial surface 11 and one end of lateral surface 12 pass through top surface 13 interconnect, the other end is open-ended state, namely wear hole 15, the side of medial surface 11 and lateral surface 12 passes through connection face 16 interconnect, medial surface 11, lateral surface 12, top surface 13 and connect and enclose into storage tank 14 that is used for holding the tooth in the middle of face 16, that is to say, the two sides of storage tank 14 are medial surface 11 and lateral surface 12 respectively, its both ends are connection face 16, the up end is top surface 13, the lower extreme is for wearing hole 15, wear hole 15 and storage tank 14 communicate with each other, when using and correcting stealthy device 1, from wearing hole 15 and covering stealth, after the invisible orthodontic device 1 is worn, the wearing hole 15 is located at one end close to the gum, the teeth are placed in the accommodating groove 14, the inner side face 11 is located at one side close to the tongue, the outer side face 12 is located at one side close to the cheek, the top face 13 covers the upper surfaces of the teeth, and the top face 13 is provided with at least one opening.

The utility model provides a pair of device 1 is rescued in stealthy of no occlusal surface, device 1 is rescued in stealthy and is divided into molar area and anterior tooth district, and is corresponding, when wearing stealthy device 1 of rescuring, the tooth of holding also divide into molar area and anterior tooth district in the storage tank 14, and the upper surface of the tooth in the molar area is called the occlusal surface, and the upper surface of the tooth in the anterior tooth district is called the tip, and the molar is divided into left molar area and right molar area.

As shown in fig. 2, in the present embodiment, the opening of the top surface 13 includes a through hole 131 penetrating through the anterior teeth area and the molar area, the through hole 131 covers the entire anterior teeth area and the molar area and is communicated with the receiving groove 14, at this time, the periphery of the through hole 131 is surrounded by the upper surfaces of the inner side surface 11, the outer side surface 12 and the connecting surface 16, when the invisible orthodontic device 1 is worn on the teeth, the through hole 131 does not cover the incisal ends of the teeth in the anterior teeth area and the occlusal surface of the teeth in the molar area, so that the upper surfaces of the entire row of teeth can be completely exposed.

In this embodiment, since the top surface 13 includes the through hole 131, two openings are formed at two ends of the accommodating groove 14, that is, the through hole 131 and the wearing hole 15, and both the through hole 131 and the wearing hole 15 are communicated with the accommodating groove 14, when the invisible orthodontic device 1 is used, the invisible orthodontic device 1 can be worn on teeth through the wearing hole 15, after the invisible orthodontic device 1 is worn, the wearing hole 15 is an opening close to a gum, the through hole 131 is an opening far away from the gum, the through hole 131 can expose the cut ends of all teeth in the anterior tooth area and the occlusal surfaces of all teeth in the molar area, so that the upper and lower teeth can be occluded with each other through the upper surfaces of the upper and lower teeth, thereby facilitating adjustment and establishing of a stable occlusion relationship, preventing disorder of the final occlusion relationship, and at the same time, saliva or bubbles and residues of liquid food in the invisible orthodontic device can be discharged at any time through the, solves the problem of bacteria and tooth demineralization, and improves the sanitary environment in the oral cavity when the orthodontic device is worn.

As shown in fig. 5 and 6, which respectively show the side views of the anterior teeth and molar teeth when the invisible orthodontic device 1 is worn on the teeth, it can be seen that the two sides forming the through hole 131 include slopes with the same structure, i.e. the upper surfaces of the inner side surface 11 and the outer side surface 12 are respectively provided with a first slope 111 and a second slope 121, and since the first slope 111 and the second slope 121 have the same structure and opposite directions, the following description will be made in detail by taking only the first slope 111, i.e. only the inner side surface 11 as an example.

As shown in fig. 7, the first slope 111 is disposed on the upper surface of the inner side surface 11, the inner side surface 11 further includes a tooth connection surface 112 close to the tooth and an outer contact surface 113 far from the tooth, the first slope 111, the tooth connection surface 112 and the outer contact surface 113 are respectively provided with a boundary, that is, the boundary between the first slope 111 and the tooth connection surface 112 is a highest boundary 1111, the boundary between the first slope 111 and the outer contact surface 113 is a lowest boundary 1112, the first slope 111 gradually decreases from the highest boundary 1111 to the lowest boundary 1112 to form an inclined plane, that is, the first slope 111, the inclined structure of the first slope 111 enables the liquid food to flow out along a direction in which the first slope 111 decreases, so as to prevent the liquid food from entering the inner side of the invisible orthodontic device 1, thereby solving the problems of bacteria generation and tooth demineralization, and improving the hygienic environment in the oral cavity when the orthodontic device is worn.

The first slope 111 is a straight plane, the highest boundary point 1111 is provided with an inner side tangent line m along the tooth connecting surface 112, an included angle between the plane where the first slope 111 is located and the inner side tangent line m is alpha, the value of alpha is between 20 and 40 degrees, and the preferred value is 30 degrees; the lowest intersection point 1112 is provided with an outer tangent n along the outer contact surface 113, an included angle β between a plane of the first slope 111 and the outer tangent n is between 130 degrees and 150 degrees, and a preferred value is 140 degrees.

Preferably, the boundary between the first slope 111 and the outer contact surface 113 is arc-shaped, that is, the outer surface of the lowest boundary 1112 is arc-shaped, and since the lowest boundary 1112 is usually located at a position contacting the lingual side or the buccal side when the invisible orthodontic device 1 is actually used, the arc-shaped lowest boundary 1112 is configured to reduce damage to the inside of the oral cavity.

Example 2

The structure in this embodiment is substantially the same as that in embodiment 1, except that:

the opening of the top surface 13 comprises two occlusion holes 132 arranged in the molar area, the two occlusion holes 132 are respectively covered on the left molar area and the right molar area on the top surface 13, that is, the engaging holes 132 are formed on the top surfaces 13 of the left molar region and the right molar region, respectively, and when the invisible orthodontic device 1 is used, the occlusal holes 132 do not cover the occlusal surfaces of the teeth in the molar region, so that the occlusal surfaces of all the teeth in the molar region may be exposed, can ensure that the upper and lower occlusal surfaces of the upper and lower teeth are occluded with each other, is beneficial to adjusting and establishing stable occlusion relation, prevents disorder of the final occlusion relation, meanwhile, the occlusion holes 132 can discharge saliva or air bubbles and residues of liquid food in the invisible correcting device at any time, and does not influence the aesthetic degree and the comfort level, solves the problems of bacteria generation and tooth demineralization, and improves the sanitary environment in the oral cavity when the orthodontic device is worn.

The detailed description of the embodiments of the present invention has been presented above, and it will be apparent to those skilled in the art that the present invention can be modified and improved without departing from the principles of the present invention, and the modifications and improvements also belong to the protection scope of the claims of the present invention.
