Description

Technical Field

[0001] The utility model relates to the field of oral arch expansion, in particular to an implant nail combined arch expander. Background Art

[0002] In cases of crowded teeth, narrow jaws and bite problems, the bite is not normal.

[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0028] First embodiment:

[0029] See also Figure 1-Figure 5 As shown, the utility model provides an implant-pin combined arch expander, comprising a thruster 1, both sides of the thruster 1 are connected to a fixing frame 3 through a thrust frame 2, the fixing frame 3 corresponds to the position of the molar in the oral cavity, the thruster 1 and the thrust frame 2 are arranged close to the inner side of the oral cavity, the fixing frame 3 comprises a winding frame 301 and a semi-ring frame 302, the semi-ring frame 302 is a semi-arc surface, and is located on the inner side of the tooth, the semi-ring frame 302 is located on the outer inner side of the tooth, and the winding frame 301 and the semi-ring frame 302 are respectively arranged on the outer sides of adjacent teeth;

[0030] Among them, at least one fixing frame 3 corresponds to the implant nail, and also includes a fixing sleeve 4, which can be detached from the outside of the implant nail and fixedly connected to the winding frame 301 on the fixing frame 3 corresponding to the implant nail;

[0031] When the device is in use, it is mainly used in the oral cavity with implant nails. When installing, the oral cavity is molded, and the device is made according to the tooth mold, so that the thruster 1 and the thrust frame 2 are close to the inner side of the oral cavity, and the fixing frame 3 is located outside the teeth and the implant nails. The fixing sleeve 4 is set at the position where the implant nail exists. When installing, the fixing sleeve 4 is passed through the outside of the implant nail, and the implant nail position is connected and clamped by the fixing sleeve 4. See Figure 1 As shown, the fixing sleeve 4 is an annular or semi-annular structure. When the fixing sleeve 4 is a semi-annular structure, it is an optimal ring, which can be connected around the frame 301 and the implant nail position to form a multi-tooth connection structure integrated with the implant nail at the implant nail position, which has a better supporting effect during arch expansion and can form a symmetrical structure inside the oral cavity, which can push multiple teeth to expand the arch side by side and assist in tooth correction.

[0032] The second embodiment is different from the first embodiment in that:

[0033] The thruster 1 includes two mounting blocks 105, and the facing sides of the mounting blocks 105 are connected with threaded rods 103. The threaded rods 103 on the two mounting blocks 105 rotate in opposite directions. The outer sides of the two threaded rods 103 are threadedly connected with threaded sleeves 104, and the threaded sleeves 104 are provided with rotating holes. When adjusting the thruster 1, a tool is inserted into the rotating hole and the threaded sleeves 104 are rotated. The threaded sleeves 104 rotate, and the threaded rods 103 can be moved in the threaded sleeves 104 by means of threaded connection, so that the distance between the two mounting blocks 105 can be adjusted. In a preferred embodiment, the mounting block 105 is provided with an insertion rod 101, and the other mounting block 105 is provided with a slide groove 102 that is clearance-matched with the insertion rod 101. The sliding fit between the slide groove 102 and the mounting block 105 can guide the two mounting blocks 105, so that the distance between the two thrusters 1 becomes larger, thereby improving the supporting strength of the thrust frame 2 to the fixed frame 3, and assisting in tooth correction.

[0034] The third embodiment is different from the first embodiment in that:

[0035] The movable ends of the thrust frame 2 are respectively connected to the mounting block 105 and the semi-ring frame 302. The thrust frame 2 is provided with a protective rib 201 corresponding to the winding frame 301. The protective rib 201 is close to the gums at the position of the winding frame 301. The thrust frame 2 mainly supports the fixing frame 3 by pushing the semi-ring frame 302. At the position of the implant nail, the winding frame 301 and the fixing sleeve 4 are connected to form an integral whole to achieve traction on the implant nail position, which can not only ensure the supporting effect of the thrust frame 2 on the oral cavity, but also avoid the situation where the implant nail position is subjected to excessive force.

[0036] Further, there are two semi-ring frames 302, and the two semi-ring frames 302 are respectively located on both sides of the winding frame 301, that is, the two semi-ring frames 302 and one winding frame 301 correspond to the positions of three teeth, wherein the winding frame 301 can correspond to the position of the implant nail. In this way, the force at the position of the semi-ring frame 302 is used to push the position of the implant nail, assist the implant nail and the pushing expansion of the two sides, and realize the auxiliary shaping of the teeth. The thrust frame 2 is "Y" shaped or strip-shaped, see Figure 1 , Figure 5 shown.

[0037] Specifically, when the winding frame 301 corresponds to the implant nail, that is, the position of the fixing frame 3 corresponds to the implant nail, see Figure 1 , Figure 3As shown, the winding frame 301 is a segmented structure, and the winding frame 301 and the semi-ring frames 302 located on both sides thereof constitute a continuous curved structure, the semi-ring frames 302 correspond to the inner side of the teeth, and the winding frame 301 corresponds to the outer side of the teeth at the position of the implant nail, and the winding frame 301 is connected to the fixing sleeve 4. After installation, the fixing sleeve 4 is located on the outside of the implant nail, which can make multiple teeth together form an integral structure connected to the implant nail position, so that when the thrust of the thrust frame 2 is received, it can promote correction based on multiple teeth, and the correction effect is achieved.

[0038] When the position of the fixing frame 3 does not correspond to the implant pin, that is, for the inner side of the oral cavity with an implant pin on one side, when the wrapping frame 301 corresponds to the teeth, the wrapping frame 301 is a closed frame structure and is arranged on the outer side of the teeth. This arrangement can form a simple symmetrical structure on the inner side of the oral cavity, and the fully closed state of the wrapping frame 301 is used to form a wrap around the teeth. When the thrust frame 2 supports the semi-ring frame 302, the wrapping frame 301 is used to support the middle tooth position, thereby achieving the pushing of multiple teeth and improving the supporting effect.

[0039] Furthermore, the surrounding frame 301 and the semi-ring frame 302 are transitioned in an arc.

[0040] The fourth embodiment is different from the first embodiment in that:

[0041] The two sides of the thruster 1 are connected with tooth sleeves 6 through connecting arms 5. The tooth sleeves 6 are closed frame structures arranged on the outside of the teeth. The tooth sleeves 6 correspond to the positions of the canines / lateral incisors. The positions of dental implants are mostly close to the inside of the oral cavity. For a "V"-shaped oral cavity, the opening side also needs to be expanded, and the connecting arms 5 and tooth sleeves 6 are used to form support for the teeth on the opening side.

[0042] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
