Detailed Description

The present invention is described in terms of particular embodiments, other advantages and features of the invention will become apparent to those skilled in the art from the following disclosure, and it is to be understood that the described embodiments are merely exemplary of the invention and that it is not intended to limit the invention to the particular embodiments disclosed.

Examples

As shown in figures 1-5, the present invention provides a bony class III errorDeformity correction method and bone type III malocclusionThe deformity correction method comprises the following steps:

s1, in the dentition alignment stage, the multi-effect nickel titanium arch wire 1 is used for rapidly aligning teeth, and anterior occlusion obstacles are removed;

s2, after the anterior teeth are aligned, the lower jaw implant anchorage nail 2 is matched with the constant force tension spring 3 to retract the anterior teeth and remove the inverse anterior teeth

S3, anterior tooth opposite directionAfter the release, using TMA silk 4 step curve to lift the upper and lower posterior teeth to quickly establish the occlusion relation of the posterior teeth and synchronously establish the normal coverage of the anterior teeth;

s4, keeping the front teeth covered normally, and lifting and clockwise inclining the lower jaw backPlane, then lip-tilt the anterior teeth, promote the lower jaw to rotate clockwise, and guide the lower jaw chin to retreat;

and S5, adjusting the occlusion stage and observing the condition of the patient.

As described above, in the dentition alignment stage, as shown in FIG. 2, the fixing positions of the archwire and the plurality of brackets 6 are determined, the brackets 6 are stuck to the teeth according to the determined position relationship, and the multi-effect nitinol archwire 1 is used to connect the plurality of brackets 6 in series to align the teeth rapidly. The multifunctional nickel-titanium arch wire 1 is used for quickly aligning teeth, and the principle is as follows: the multi-effect nickel-titanium arch wire 1 realizes the super-elasticity performance of a posterior tooth section and the thermal activation performance of an anterior tooth section on a preformed arched nickel-titanium arch wire, and has the characteristics of flexibility, fracture resistance and high strength. The force is applied evenly in the aligning and leveling stage, so that the crowding and twisting of the anterior tooth area are relieved efficiently while the stability of the posterior tooth support is enhanced. The elasticity is better, and the friction force with the clearance of holding in the palm groove 6 is less, is favorable to the tooth to remove, aligns the dentition.

In addition, as shown in fig. 3, when the lower teeth are stuck to the bracket 6, the lower jaw implant anchorage nail 2 is implanted into the dental alveolus at the rear side of the lower anterior teeth, and after the anterior teeth are aligned, one end of the constant tension spring 3 is connected to the lower jaw implant anchorage nail 2, and the other end is connected to the lower anterior teethOn the multi-effect nickel-titanium arch wire 1 at the tooth, the anterior teeth are retracted inwards and the anterior tooth reversal is relievedWherein, the constant force tension spring 3 is preferably 100-150 g constant force tension spring. On the basis of this, due to the inverseWhen the patient receives the lower anterior teeth, the torque is controlled to prevent the lower anterior teeth from inclining to the tongue (the inclined lower anterior teeth can cause the protrusion of the lower jaw and the chin to be more remarkable, and the bony class III surface shape is aggravated). Therefore, before the constant tension spring 3 is connected, a draw hook is attached to the lower anterior tooth on the stainless arch wire, and one end of the constant tension spring 3 close to the lower anterior tooth is hooked on the draw hook to apply an adduction force with torque control to the anterior tooth.

Anterior reversal of toothAfter the occlusion wound is relieved, the occlusion contact of the posterior teeth needs to be established in time, and the occlusion wound of the anterior teeth can be effectively relieved by utilizing the occlusion support of the posterior teeth. The establishment of the posterior occlusal contact is therefore in particular: a TMA wire 4 of model 1925 was used in the lower jaw to make a step-up in the distal cuspid to raise the posterior teeth (refer to fig. 4) and simultaneously make a vertical short pull on the posterior teeth to stabilize the new position of the mandibular retrogradation and remove the anterior occlusal wound. On the basis of the above-mentioned condition, i.e. on the premise of maintaining normal covering of anterior teeth, the lower jaw rear portion can be raised and clockwise inclinedFlat to encourage clockwise rotation of the mandible, which recedes. The lower anterior teeth are inclined in parallel, the inclination of the lips of the lower anterior teeth adopts a mode that a plurality of brackets 6 on the lower anterior teeth are inverted to obtain a torque of six degrees, and meanwhile, a five-bent connecting spring 5 (refer to figure 5) is placed in a gum space of the inverted brackets 6 so as to further promote the clockwise rotation of the lower jaw, guide the lower jaw to retreat, increase the control of the positive torque on the lower anterior teeth, and be beneficial to improving the reverse torqueThe anterior mandibular protrusion shape.

In addition, a portal auxiliary arch is installed over the stainless steel archwire at the cuspids during the adjusted bite phase to increase the cuspid negative torque and promote stabilization of the mandibular chin in a retracted new position. Namely, the lower anterior labial inclination is realized along with the inclination of the posterior occlusal plane of the lower jaw, and under the premise of keeping the normal coverage of the anterior teeth, the relative retreat of the lower jaw chin can effectively improve the protrusion of the lower jaw and the reverse protrusionThe surface type of (1).

Preferably, the multi-effect nitinol archwire 1 is replaced with a stainless steel archwire on the upper anterior teeth after normal coverage of the anterior teeth has been established, if necessary, while the pentagonal connecting spring 5 is installed at the incised end to increase control of the negative torque of the upper anterior teeth.

The embodiment of the invention is based on the combination of novel orthodontic materials (mainly comprising a multi-effect nickel-titanium arch wire 1, a constant force tension spring 3, a TMA wire 4, a five-curved connecting spring 5 and a door-shaped auxiliary arch), firstly, the multi-effect nickel-titanium arch wire 1 is utilized to quickly align teeth, and under the premise of removing occlusion obstacles of anterior teeth, the lower jaw planting anchorage nail 2 and the constant force tension spring 3 are utilized to retract the anterior teeth to remove the inverse anterior teethAnterior tooth reversalAfter the release, the upper and lower posterior teeth are lifted by using TMA wire 4 step curve, the posterior occlusion relation is quickly established, the new position of the retroversion of the mandible is stabilized, the occlusion wound of the anterior teeth is removed, and the rear part of the mandible is lifted and inclined clockwise on the premise of maintaining the normal coverage of the anterior teethPlane to promote the mandible to rotate clockwise, the mandible chin retreats, the anterior teeth are inclined by lips, the condition of the patient is observed by adjusting the occlusion stage finally, thereby the non-extraction correction of adult cases of bony mandibular protrusion can be completed without complicated operations such as operation or tooth extraction, the mandibular protrusion can be effectively improved,improvement ofThe surface type of (1).

Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
