Background
The micro-implant nail is widely applied to orthodontic clinical application for tooth reduction, and in view of the linear design of the micro-implant nail, the implant nail is implanted to be vertical to the surface of a bone so as to conveniently apply external force. The method has the following defects: since the micro-implant nail is preferably implanted at the membrane-gingival junction to avoid the proliferation of mucous membrane soft tissues to surround the implant nail, the membrane-gingival junction is close to the gingival margin in many cases, about 2-3 mm, which means that the implantation point of the micro-implant nail is close to the neck of the tooth. At the moment, the risk is higher, because the implantation point of the micro implantation nail is closer to the neck of the tooth, the distance between the tooth roots is smaller, the risk of damaging the tooth roots is increased, and the probability of failure of the implantation nail is increased; the implant nail is close to the neck of the tooth, which means that the space for the vertical displacement of the tooth is limited, after a small amount of teeth move, the tooth root can touch the micro implant nail, if more teeth move, the micro implant nail needs to be implanted again at the position of the root, and the micro implant nail is implanted for a plurality of times, so that the cost is increased and the discomfort of a patient is also increased.
Disclosure of Invention
The utility model aims at providing a supplementary A1 micro-planting nail applys device of holding down force, and A1 micro-planting nail only need parallel root of a tooth to implant, consequently can utilize bone tissue more, is favorable to the long-term stability of micro-planting nail, and the part that micro-planting nail passed the mucous membrane is close to membrane gum joint department, can avoid soft tissue hyperplasia.
The purpose of the utility model is realized by adopting the following technical scheme.
The device for assisting the A1 micro-implant nail to apply the depression force comprises a base, a main body arranged on the base and a force application part; the base is a hollow shell which can be sleeved at the upper end of the A1 micro planting nail; two ends of the stress application part are respectively provided with a hook and a slide block; the buccal side of the main body is provided with a horizontal sliding groove parallel to the occlusal plane, and the force application part is connected with the horizontal sliding groove of the main body through a sliding block.
In a preferable technical scheme, the base is fixed with the upper end of the A1 micro-implant nail through a screw.
In a preferred technical scheme, a plurality of clamping grooves which are vertical to and communicated with the horizontal sliding grooves are further formed in the cheek side face of the main body, the clamping grooves extend towards the occlusal plane direction, and the sliding blocks of the force application parts are matched with the clamping grooves.
In a preferred technical scheme, the number of the clamping grooves is 4, and the number of the force applying components is 2.
In a preferred technical scheme, the base is matched with the upper end of the A1 micro planting nail.
The utility model has the advantages that:
(1) the device enriches the implantation direction of the implant nail, and particularly can implant the implant nail parallel to the tooth root in the case that the implant nail needs to be pressed down more vertically.
(2) The parallel tooth root is implanted into more bone tissues which can be utilized, the long-term stability of the micro-implant nail is facilitated, and the part of the micro-implant nail penetrating through the mucous membrane is close to the membrane-gum joint, so that the soft tissue hyperplasia is avoided
(3) The device is connected with the micro-implant nail simply, and the force application sites are diversified, thereby facilitating clinical use.
