Technical Field

The invention discloses a special micro titanium plate for mucosa external fixation of an orthodontic implant anchorage system, relates to the technical field of orthodontic clinical, and particularly relates to an auxiliary material for orthodontic implant anchorage.

Background

The existing planting anchorage has great influence on the oral orthodontic clinical diagnosis and treatment, greatly enriches the design content of the orthodontic traditional anchorage, widens the range of the traditional orthodontic treatment, lightens the spirit and the economic burden of a patient, and provides new treatment selection and economical and practical service for the patient. The micro titanium plate anchorage system does not damage the tooth root when being implanted or the tooth moves in a larger range because the retention pin is far away from the tooth root. The two fixing nails are fixed, the stability is strong, the falling rate is extremely low, and the ideal anchorage effect can be provided for treating various complex malocclusion deformities. The micro titanium plate anchorage system has been developed for nearly thirty years, particularly, the materials, the process, the form and the retention mode are continuously improved, the localization is realized, the cost is low, the economic burden of patients is reduced, the surgical injury to the patients is obviously reduced, the operation of doctors is simple and convenient, the curative effect is good, more patients can be favored, and the clinical popularization is facilitated.

The traditional anchorage system for the micro-titanium plate planting has the following problems:

1. the incision of the mucous membrane is large, the surgical injury easily causes the conflict and fear of patients, and the physical and mental burden and the economic burden of the patients are increased;

2. the micro titanium plate has larger volume, larger stimulation to mucous membrane, red and swollen mucous membrane often appears, the titanium plate is wrapped by a serious person, and the red and swollen mucous membrane must be cut off during dismantling;

3. the micro titanium plate is fixed by the front nail and the rear nail, the front nail is stressed greatly and is easy to fall off, and the stability of the whole planting anchorage system is influenced;

4. the length of the micro titanium plate can not be adjusted, because the tooth root position of each patient is different, the retention is difficult clinically, and the severe patient can generate side effects such as torsion after retention, which affects the stability of the implant anchorage system and causes discomfort to the patient;

5. the traction hook on the micro titanium plate can not be adjusted, and the achievement of a treatment target can be influenced due to uneven force on two sides due to the change of the retention position;

6. the traction hook of the micro titanium plate can not be adjusted, and the mucous membrane or the force application directions and the sizes of the two sides of the patient can be pressed.

Aiming at the problems in the prior art, a novel special miniature titanium plate for fixing the mucosa outside of the orthodontic implantation anchorage system is researched and designed, so that the problems in the prior art are very necessary to be overcome.

In view of the problems in the prior art, the invention aims to research and design a novel special miniature titanium plate for fixing the mucosa outside of the orthodontic implantation anchorage system, which is used for realizing small injury of the mucosa of a patient, wide implantation positions, simple clinical operation, stable and effective anchorage, no need of complex processing technology in production, availability of both sides of the maxilla and contribution to orthodontic clinical popularization. Especially, the application in the early anterior traction treatment of the osseous III type mismatching deformity (ground wrapped sky) has obvious curative effect, and the application is not reported at home and abroad at present.

Disclosure of Invention

The micro titanium plate proposed according to the prior art has a large volume and causes large stimulation or damage to the mucosa; the length can not be adjusted, so that the implantation difficulty is increased, and the fixed retention nail and the titanium plate can generate side effects such as torsion and the like, so that the stability of an anchorage system is influenced, and the curative effect is further influenced; the forearm fixing screw is stressed greatly, is easy to fall off and has poor stability; the traction hook can not be adjusted, the mucous membrane of a patient can be pressed or the forces on the two sides are inconsistent, and the like, thereby providing the special micro titanium plate for fixing the mucous membrane of the anchorage system for the orthodontic implantation. The invention mainly utilizes the rotary joint to movably connect the front and rear arms with the traction hook, thereby realizing the arm extension length change of the front and rear walls and the movement of the traction hook, thereby achieving the purposes of realizing small mucous membrane damage of patients, obviously reducing uncomfortable feeling, properly adjusting the implantation position according to the position of the tooth root, having flexible and simple clinical operation, stable and effective anchorage, not needing complex processing technology in production, being capable of being used on both sides of the upper jaw bone, being beneficial to clinical popularization, reducing the proportion of tooth extraction or operation and benefiting more patients.

The patent is applied to the treatment of orthodontic clinical difficult and complicated cases, integrates the advantages of various implantation anchorage into a whole, is simple to operate, can be implanted according to different positions of teeth, can simplify the treatment, has small damage and good anchorage effect, provides non-tooth extraction or non-operative treatment opportunities for patients, and realizes all the supreme medical concepts of the patients.

The technical means adopted by the invention are as follows:

a special miniature titanium plate for mucosa external fixation of an orthodontic implantation anchorage system comprises: a front wall, a rear wall and a towing hook;

furthermore, the front arm is an arc-shaped thin plate made of pure titanium, and a fixing screw hole is processed at the front end of the front arm;
