Description
Technical Field
The utility model relates to an orthodontic field in the oral cavity especially relates to cover just abnormal auxiliary device of jaw deeply.
Background
Occlusion control is one of the key technical points of orthodontic treatment, and the best aesthetic and functional effects can be obtained only through good anterior occlusion. In the normal vertical occlusion relation, the upper anterior teeth are occluded within 1/3 of the incision of the lower anterior dental crown, or the incisal margin of the lower anterior teeth are occluded within 1/3 of the lingual incision of the upper anterior teeth; while those exceeding 1/3 are called deep covering jaw. During orthodontic treatment, the control of anterior occlusion is one of the guarantees of success of treatment. However, in the case of permanent orthodontic extraction, it is difficult to control occlusion by depressing anterior teeth. On one hand, due to the existence of tooth extraction gaps, the orthodontic arch wire has a stress interruption effect in the middle section of the dental arch, so that the control strength of the arch wire is weaker, and the orthodontic force loading is difficult to completely transmit to anterior teeth. On the other hand, the side effect of tooth movement in the process of tooth extraction correction is that in the process of adduction of the anterior teeth, correction force acts on the bracket and the arch wire to pull the anterior teeth backwards, and the mechanical direction of the correction force is positioned in the jaw direction of the impedance center of the anterior teeth, so that the anterior teeth have the tendency of tongue inclination and elongation movement, and the occlusion is deepened. Particularly, as the implant anchorage screw is widely used in the orthodontic field, more and more patients adopt posterior implant screws to adduct anterior teeth as much as possible, thereby improving the teeth and the facial convexity to the maximum extent. However, in this case, the tooth extraction gap is closed by the adduction of the anterior teeth, and the side effect phenomenon of the tooth movement is more remarkable because the distance of the anterior teeth movement is excessively long, and the anterior occlusion control is extremely difficult. Furthermore, if the patient has clinical manifestations of deep jaw coverage immediately before treatment, it is difficult to depress the anterior teeth during treatment.
The current common anterior occlusion control method in clinic is to implant 1-2 planting nails into the anterior teeth or use the traditional pressing auxiliary arch, but the two methods have obvious defects. The implant anchorage is directly implanted at the root tip of the anterior tooth area, and the arch wire of the anterior tooth area is suspended and drawn by the elastic rubber chain, so that the anterior tooth is pressed into the gum, and the depression efficiency is high. However, because 1-2 implant anchorage nails are required to be additionally implanted into a patient, the negative effects of various implant anchorage nails are undoubtedly caused, and the possibility of trauma, bleeding, pain and infection is included; the width and the thickness of the alveolar bone between the anterior tooth roots are generally narrow, the operation difficulty of implanting the implant nail is high, high clinical experience of doctors is required, otherwise the risks of tooth root injury, alveolar bone punch-through and the like are easy to occur; the frenulum and the lip mobility in the anterior dental area are high, and the planting nail is easy to rub with the soft tissues to cause traumatic ulcer; and the gingiva in the anterior tooth area is easy to be inflamed and proliferated to cover the planting nail, so that unnecessary operation and pain are caused, and the correction efficiency and the comfort level of a patient are reduced. The traditional auxiliary arch for lowering is to bend the arch wire into a specific shape and to lower the front teeth by the resilience force of the arch wire. However, the auxiliary arch is a segmented arch wire, which only incorporates anterior teeth and molars but skips the anterior molars, and is used in a way that the anterior teeth are firstly pressed down and then replaced by a common arch wire to arrange all teeth, so that the operation undoubtedly greatly increases the treatment time and reduces the treatment efficiency. And its side effect is very obvious, and anterior teeth can actually take place certain labial slope and move, this is unfavorable for anterior teeth adduction, also easily takes place alveolar bone fracture, the risk of gum recession. At the same time, the molars undergo uncontrolled movements of distal tilting and elongation, which are detrimental to the functional occlusion of the posterior teeth. In view of the above, there is a need in the clinical field for a simple and efficient method for controlling anterior occlusion.
The chinese patent CN202821676U discloses an anterior teeth depression elastic auxiliary arch, and specifically discloses the following: the front tooth low-pressure elastic auxiliary arch comprises an arc arch wire body and a left hook and a right hook which are arranged at the two tail ends of the arch wire body, wherein the arch wire body is respectively provided with an upward left bend and an upward right bend at the positions corresponding to the far middle or near middle of two cuspids, so that the part of the arch wire body corresponding to the cuspids is folded upwards to form an upper arch-shaped body at the front part. The left and right bends of the arch wire body and the left and right hooks are respectively provided with a second bend, which can also increase the elasticity of the arch wire. During the use, use with main arch silk cooperation for when correcting the maxillary tooth, the upper jaw assist the arch through left and right couple forward hang on the main arch wire of maxillary tooth, anterior upper bow shape arc body up this moment, just to the direction of upper jaw gum, left and right couple correspond hang position … … between upper jaw both sides second premolar and the first molar and then assist the upper bow shape arc body of arch and fix through ligature silk and the main arch silk ligature that corresponds the maxillary anterior tooth position with the upper jaw. When the left and right hooks are used for correcting mandibular teeth, the mandibular auxiliary arch is respectively and reversely hung on the main arch wire of the mandibular teeth through the left and right hooks, the upper arch-shaped arc-shaped body at the front part faces downwards and is just opposite to the mandibular gingival, the left and right hooks are correspondingly hung at the position between the second premolars and the first molar at the two sides of the mandibular teeth, if the mandibular second molar is brought into a correcting system, the hook position is between the first molar and the second molar.
The anterior teeth depression resilient auxiliary arch used in the above patent is provided with a supporting force for the anterior teeth depression by the posterior teeth and the main arch wire, which causes the posterior teeth to extend during the force application process, and although the occlusion can be opened, the posterior teeth extension may cause other side effects, including the deterioration of the plane shape due to the out-of-plane control of a high-angle patient, or the generation of joint problems due to the interference of the posterior jaw, and the like.
