Description

TECHNICAL FIELD

[0001] The utility model relates to orthodontic implant nail technical field, specifically related to a connecting piece for implant nail. BACKGROUND

[0002] Implant nail is a kind of fixed device for orthodontic treatment, usually made of high-strength titanium alloy or other biocompatible materials. Implant nail can be implanted in alveolar bone by surgical method, as stable anchorage point, combined with traction rubber band to assist in correcting tooth movement and adjusting jaw position. Implant nail can provide durable and stable support, reduce the dependence on adjacent teeth, thereby improving the efficiency and effect of orthodontic treatment.

[0003] In the process of orthodontic treatment, implant nail is easily wrapped by soft tissue after being implanted in alveolar bone, especially the implant nail in the lower jaw buccal shelf area is more prone to soft tissue hyperplasia. The implant nail wrapped by soft tissue will affect the traction of the traction rubber band in orthodontic treatment, resulting in weakened anchorage effect, and it is difficult to effectively play the anchoring role of implant nail. UTILITY MODEL CONTENT

[0004] The utility model aims at providing a connecting piece for implant nail, which connects the screw cap of implant nail through protective cover, and then extends the load-bearing piece away from implant nail by connecting rod, so that the implant nail wrapped by hyperplastic soft tissue can also play the function of implant nail through connecting piece by using indirect anchoring effect.

[0005] The utility model realizes the following technical scheme:

[0006] A connecting piece for implant nail, comprising a connecting cover, the connecting cover is used to be connected to the screw cap of implant nail, a connecting rod is connected to the connecting cover, and a load-bearing piece is connected to the connecting rod.

[0007] In the technical scheme, the connecting piece is used as the accessory of orthodontic implant nail, and the connecting cover is used to be directly or indirectly connected to the screw cap of implant nail. The connecting cover can be in various setting modes, and in one or more embodiments, the connecting cover can be a cuboid, prism or other structure without curved surface. In some preferred embodiments, the connecting cover can be a hemisphere or semi-ellipsoid with curved surface. By placing the screw cap into the opening of the connecting cover, the connecting cover can cover the screw cap. In some preferred embodiments, the bottom of the connecting cover can be further provided with a cylindrical sleeve ring, and the sleeve ring is arranged outside the screw cap.

[0008] In the technical solution, the connecting mode of the connecting cover and the nut is to use medical resin adhesive for bonding. After bonding, the connecting piece and the implant nail form stable connection. The connecting rod on the connecting cover extends the load bearing piece away from the implant nail. The load bearing piece is preferably an annular structure provided with an opening to allow the traction rubber band to be sleeved on the load bearing piece. Finally, through the cooperation of the traction rubber band and the orthodontic buckle arranged on the tooth, a stable traction force is formed on the tooth where the orthodontic buckle is arranged.

[0009] In some preferred embodiments, the length of the connecting rod is adjustable. By adjusting the length of the connecting rod, the direction of the traction force can be changed, providing better flexibility in clinical treatment.

[0010] Through the above arrangement, the two ends of the connecting piece are connected to the implant nail and the traction rubber band respectively. The indirect anchorage effect is utilized. Even if the implant is wrapped by the proliferating soft tissue, the function of the implant can be exerted through the connecting piece. At the same time, the connecting piece has a simple structure and is easy to install. The stable connection of the connecting cover and the nut of the implant nail can be achieved by using medical adhesive, which has wide application value.

[0011] Further, the connecting cover is a hollow hemisphere, and a sleeve ring is connected to the bottom of the connecting cover, and the inner diameter of the sleeve ring is greater than the diameter of the nut.

[0012] In the technical solution, the connecting cover is a hemispherical structure, the inside of the connecting cover is hollow, and the bottom of the connecting cover is connected to a sleeve ring with an inner diameter greater than the diameter of the nut. Therefore, when connecting, the sleeve ring can be covered outside the nut. When installing, adhesive is applied on the nut or inside the connecting cover and the nut, and then the sleeve ring is sleeved on the nut to form stable bonding of the connecting cover and the nut.

[0013] In the technical solution, by sleeving the hemispherical connecting cover and the cylindrical sleeve ring on the nut, the nut exposed outside the alveolar bone of the implant nail can be replaced by the curved connecting cover, thereby effectively reducing the soft tissue proliferation around the implant nail. This is because, on the one hand, the curved connecting cover is not easy to accumulate food residues, thereby being not conducive to the growth of bacteria and reducing soft tissue proliferation. On the other hand, the curved connecting cover and the sleeve ring can reduce the stimulation to the surrounding soft tissue, to a certain extent, reducing the proliferation or ulceration of the soft tissue.

[0014] Further, a plurality of first through holes are arranged on the connecting cover, and the first through holes communicate the inside and outside of the connecting cover.

[0015] In order to realize the stable connection of the connecting cover and the screw cap, usually, excess adhesive is added between the connecting cover and the screw cap. However, in the process of compacting the connecting cover towards the screw cap, the excess adhesive will overflow from the opening at the bottom of the connecting cover and flow towards the gum, and it is not easy to remove the excess adhesive. In the technical solution, the first through holes arranged on the connecting cover communicate the external space and the internal space of the connecting cover, so that in the process of moving the connecting cover towards the screw cap, the adhesive in the connecting cover will partially overflow from the first through holes to the surface of the connecting cover, thereby facilitating the removal of the adhesive from the surface of the connecting cover after the adhesive is dried.

[0016] Further, the number of first through holes in the central region of the connecting cover is greater than the number of first through holes in the edge region of the connecting cover. In the technical solution, by gradually reducing the number of first through holes on the connecting cover from the central region to the edge region of the connecting cover, or by concentrating the first through holes in the center of the connecting cover, the adhesive overflowing to the surface of the connecting cover can be more effectively concentrated, and the subsequent removal of excess adhesive is more facilitated.

[0017] Further, the sleeve ring is provided with a dispersion member on the inner side of the connecting cover, and the dispersion member and the connecting cover are provided with a containing cavity, and the dispersion member is uniformly distributed with a plurality of second through holes.

[0018] In the technical solution, the sleeve ring arranged at the bottom of the connecting cover forms a closed containing cavity with the connecting cover and the dispersion member. Among them, the first through holes on the connecting cover communicate the outside and the containing cavity of the connecting cover, and the second through holes on the dispersion member communicate the inside and the containing cavity of the dispersion member.

[0019] When the dispersion member is filled with adhesive and the screw cap, the excess adhesive will uniformly enter the containing cavity from the second through holes uniformly distributed on the dispersion member, and uniformly spread and distribute in the containing cavity; if there is still excess adhesive after dispersion, the adhesive in the containing cavity will overflow to the outer surface of the connecting cover through the first through holes.

[0020] In the technical solution, by additionally arranging the dispersion member in the connecting cover, not only the adhesive in the dispersion member can be better dispersed and filled in the space between the dispersion member and the screw cap, improving the stability of the bonding, but also the containing cavity plays a buffering role, so that the adhesive can also be well dispersed in the containing cavity, reducing the amount of adhesive overflowing to the surface of the connecting cover, and after the connecting member is connected to the implant, almost no excess adhesive needs to be cleaned.

[0021] Further, the diameter of the second through hole is larger than the diameter of the first through hole. By setting the diameter of the second through hole to be larger, the adhesive inside the dispersing member is facilitated to move to the accommodating cavity, thereby facilitating the flow of the adhesive inside the dispersing member and in the accommodating cavity, achieving the purpose of uniform distribution. At the same time, by setting the diameter of the first through hole to be smaller, the flow of the adhesive in the accommodating cavity to the outside of the connecting cover is effectively reduced, to a certain extent, the dispersion flow of the adhesive in the accommodating cavity is also promoted.

[0022] Further, the connecting base is arranged between the connecting cover and the connecting rod, or the connecting base is arranged between the sleeve ring and the connecting rod, and the clamping piece arranged below the sleeve ring is connected to the connecting base, and the clamping piece is used for clamping to the implant.

[0023] In the technical solution, the connecting base is additionally arranged between the connecting cover / sleeve ring and the connecting rod, and the material of the connecting base can be the same as or different from that of the connecting rod. The clamping piece connected to the connecting base is used for connecting to the part below the screw cap of the implant, such as the neck of the implant, to enhance the stability of the connection between the connecting piece and the implant.

[0024] In one or more embodiments, the connecting base can be fixedly connected to the clamping piece or hingedly connected to the clamping piece.

[0025] Preferably, the clamping piece comprises an L-shaped rod, one end of the L-shaped rod is provided with a clamping ring for clamping the implant, and the other end of the L-shaped rod is hingedly connected to the connecting base.

[0026] In the technical solution, the L-shaped rod of the clamping piece comprises a first segment and a second segment perpendicular to each other. The top end of the first segment is hingedly connected to the connecting base, and the movable end of the second segment is connected to the clamping ring for clamping the implant. In one or more embodiments, the clamping ring of the clamping piece can be made of metal and have a certain rigidity, which can be forced by the orthodontic forceps to adjust the diameter, so as to match the necks of implants of different models and form stable connections. In one or more embodiments, the clamping ring of the clamping piece can also be made of a material with a certain elasticity, so that the clamping ring can have an opening smaller than the neck of the implant. When clamped, the opening is expanded by the neck of the implant, and the neck of the implant is reset after entering the opening to form clamping.

[0027] The utility model also provides a kind of implant assembly, and the assembly includes implant, traction rubber band, orthodontic buckle and any one of the connecting piece for implant described above.

[0028] When the connecting piece is installed on the implant, the adhesive is first filled in the connecting cover of the connecting piece, then the connecting cover is buckled on the screw cap, after the connecting cover and the screw cap are stably connected, the bending degree of the connecting rod is adjusted to the required position, and the orthodontic buckle is bonded on the tooth needing traction, finally the traction rubber band is connected between the load bearing piece and the orthodontic buckle, so that the implant wrapped by the proliferated soft tissue can also play the function of the implant through the connecting piece by the indirect anchorage effect of the connecting piece.

[0029] In the technical solution, the implant can adopt any existing implant, and only the size of the connecting cover needs to be matched with the screw cap of the corresponding implant.
