Description

Dental cortical micro-implant

The present invention relates to a dental cortical micro-implant, and more particularly to a device for securing it to the oral cortical bone by means of a screw, which can be used for orthodontic treatment for aesthetic, functional remodeling of temporary fixation elements.

According to the general situation, in the case of crowded front teeth, wrong teeth of the front teeth or malocclusion, in order to improve the appearance and function, it is usually mostly orthodontic. The common method of correction is to use long-term traction correction by using corrective nails, correcting the wire, correcting the bracket, and pulling the hook.

Referring to Figure 1, conventionally, for the correction of the gums, some of the teeth 11 (usually not the incisors) are sometimes pulled out, and then the teeth 12 are pulled by the correcting wire 13 to adjust its position. There are generally a plurality of correcting brackets 14 adhered to the teeth 12, and each of the correcting brackets 14 is provided with a special correcting groove 141 for receiving the correcting wire 13. The width and depth of the special correcting groove 141 must be slightly larger than the diameter of the straightening wire 13, so that the correcting wire 13 can be prevented from falling in the direction in which the straightening groove 141 extends. Out of the special correction groove 141.

In order to provide a pulling force to the correcting wire 13, a conventional technique is to lock a correcting nail 20 on the cortical bone 10 near the molar 121, and then connect a spring 15 or rubber band to the end of the nail 20 and the correcting wire 13. Between to provide the right amount of pulling power. Such a bone nail 20 currently commercially available, as shown in Fig. 2, has a threaded tip end portion 21 through which the threaded tip end portion 21 penetrates the gum between the two teeth 12 and locks The cortical bone 10 is fixed to the bottom of the root of the second tooth 12 to provide a fixed force for correcting the tooth 12.

However, in the conventional technique or in the current literature of the world, all the correction nails 20 are directly locked into the cortical bone 10 with small nails and penetrate into the sponge tissue.

Disadvantages of existing corrective nails 20

1. It is easy to loosen: the existing correcting nail 20 directly locks into the cortical bone 10 and penetrates into the sponge tissue. The hard cortical bone 10 is cut into the soft sponge tissue, which easily causes the correcting nail 20 to loosen or fall. There are unfortunate or even swallowed serious injuries to the gastrointestinal tract.

2, a high proportion of noxious: the existing correction of the nail 20 operation, accidentally it is easy to hurt the adjacent tooth 12 root or upper sinus, and even cause nerve and blood vessel damage.

3, the use of functions is limited: only point-like projections, can not easily achieve the function of righting or pressing or pull-down, to achieve the above functions must be implanted a lot of bone nails 20, not only increase the patient's pain, but also increase the physician's The risk of injury.

Therefore, it can be seen that there are still many shortcomings in the above-mentioned conventional techniques, which is not a good design and needs to be improved.

In view of the shortcomings derived from the above-mentioned conventional technologies, the inventor of this case was improved and innovated, and after years of painstaking research, he finally succeeded in researching and developing this highly innovative invention "dental cortical micro-implant".

In view of the shortcomings of existing correction nails, the purpose of our invention is:

An object of the present invention is to provide a dental cortical micro-implant which can be fixed in a position required by a corrector, and the invention fixes the micro-tissue to the cortical bone by at least one set of screws, and is hardened. The cortical bone and the strong periosteum firmly hold the micro-implant on the cortical bone, unlike the existing bone nail locked into the cortical bone, which is only held by the loose sponge bone.

A second object of the present invention is to provide a dental cortical micro-implant which can be locked at a shallow position of the cortical bone to avoid damage to the adjacent or maxillary sinus, or even to avoid nerves. Damage to blood vessels.

Another object of the present invention is to provide a dental cortical micro-implant which can fully exert the force-applying mode required for correction without repeating the implantation of the nail, thereby greatly reducing the pain and injury of the corrector.

The dental cortical micro-implants of the above-mentioned objects, comprising: a fixing member, a connecting rod and a telescopic member; wherein the fixing member has a longitudinal column, and the bottom portion of the vertical column extends outwardly from at least two sides a set of bone plates, each of which has a screw hole, and a vertical portion is disposed at a center of the vertical column, and the wing portion is respectively provided with a left side wing and a right side wing on two sides of the vertical column, the left side, The right wing has a forwardly curved front end; and the lower end of the connecting rod is connected to the upper end of the longitudinal column; the telescopic member has a longitudinal rod, and the lower end of the longitudinal rod is connected to the upper end of the connecting rod, so that the telescopic member is supported by the longitudinal rod Displacement in the connecting rod up and down, thereby adjusting and positioning the best living place, the top of the longitudinal rod is provided with a hollow cross bar, the cross bar has a consistent perforation for the correcting wire to pass through the through hole; When the micro-implants are locked, the screws are inserted into the screw holes of each bone plate through a plurality of screws and locked at a shallow position of the cortical bone, and then the upper and lower positions of the telescopic member are adjusted to make the correcting wire pass through. In the through hole of the telescopic member, a force applying element (Eg: a spring or rubber band) connected between the micro implant with a wire correction, to provide the appropriate amount of pulling force. In this way, the micro-plants are locked to the cortical bone by a plurality of screws, so that the fixing strength and the stabilizing force can be greatly increased, the problem that the locking is not easy to be solid is not caused, and the fixing strength and the stabilizing force are increased. It can be locked at the shallower position of the cortical bone, and greatly reduce the pain of the corrector to avoid damage to the adjacent or upper sinus, or even to avoid nerve and blood vessel damage.
