Hidden orthodontic braces, buccal multi-curved spring matched with hidden orthodontic braces and buccal multi-curved spring hidden orthodontic appliance with hidden orthodontic braces

Technical Field

The invention relates to the field of tooth correction, in particular to an invisible tooth correction brace, a buccal multi-curved spring matched with the invisible tooth correction brace and an invisible buccal multi-curved spring corrector with the buccal multi-curved spring.

Background

Type iii of anserian malocclusions are one of the most common malocclusions in oral clinics, with a higher incidence in asian populations. The type iii anglerian malocclusion is usually due to either an underdeveloped maxilla or an overgrowth of the mandible or a combination of both. The patients have serious physical and psychological burdens due to the abnormal development of the appearance, occlusion and voice functions of the patients. In recent years, there has been a method of intermaxillary reciprocal anchorage retention in type III Anshi malocclusion patients using a buccal multiflexion spring orthosis. The buccal multi-curved spring corrector is characterized by that it utilizes the multi-curved springs of two sides to make the base supports of upper and lower jaws be connected, and utilizes the soft elastic force of said multi-curved springs to push upper jaw forward to promote its development, at the same time, it can inhibit excessive forward development of lower jaw, and can make lower jaw functional retreat to remove contradentate occlusion so as to form the invented inter-jaw III orthopedic force. Because the principle of the buccal multi-curved spring appliance is light force correction, the correction force is soft, physiological compression cannot be generated on the posterior wall of the joint, and the impact on the articular disc is reduced, so that the joint is stable and coordinated, the further damage to the temporomandibular joint caused by the contradentate syndonia is favorably relieved, and for functional mandibular deviation caused by early Anshi III malocclusion accompanied by unilateral contradentate syndonia, the improved buccal multi-curved spring appliance is adopted, so that the asymmetry of the mandible can be improved to a certain extent, and the buccal multi-curved spring appliance is an effective means for correcting the mandibular functional deviation in early stage; and compare in adopting the supplementary mode of correcting of extraoral draw gear, the ware is rectified to many curved springs of buccal side sets up in the patient is intraoral completely, and is littleer to patient's image influence when correcting. However, some problems and deficiencies of the buccal multi-curve spring rectifier are also found in clinic, so that the buccal multi-curve spring rectifier cannot be popularized clinically, and the problems are as follows:

(1) in the prior art, the buccal multi-curved spring corrector is usually used in combination with the upper and lower jaw base supports, for example, the buccal multi-curved spring corrector disclosed in the chinese utility model patent application No. 200620021913.2, and the replaceable buccal multi-curved spring corrector of application No. 201020623949.4, the upper and lower jaw base supports are large in size and poor in wearing comfort, and the upper and lower jaw base supports easily fall off from the dentition, so in order to strengthen the retention of the upper and lower jaw base supports, the buccal multi-curved spring corrector in the prior art is bent horizontally, and a vertical thrust is given to the upper and lower jaw base supports through the horizontal bending, so that the upper and lower jaw base supports are pressed upwards and downwards, and the purpose of preventing the upper and lower jaw base supports from falling off from the dentition is achieved. Then, the bending horizontal bending causes the structure of the buccal multi-curve spring correction device to be complex, and the manufacturing time of each correction device is usually 3-4 hours, so that the manufacturing is difficult and long, and the buccal multi-curve spring correction device is difficult to popularize clinically. Meanwhile, although the upper and lower base plates can be kept fixed by applying a vertical thrust to the upper and lower base plates through the horizontal bending, the upper and lower base plates can be applied with a larger vertical thrust through the horizontal bending, and the excessive vertical thrust applied by the horizontal bending can easily cause unnecessary movement of teeth in the processes of pushing the upper jaw to extend forwards and moving the lower jaw backwards. In addition, the upper and lower jaw base supports are only one retainer and do not have the function of invisibly correcting and aligning the teeth.

(2) The buccal multi-curved spring corrector is usually formed by bending a stainless steel wire, is buried in the upper and lower jaw base plates when in use, and is easy to break in a stress concentration area (an area where the lateral multi-curved spring corrector is contacted with the upper and lower jaw base plates) when in correction. The replaceable buccal multi-curved spring corrector of application No. 201020623949.4, which enables the replacement of buccal multi-curved springs by adhering the palatine canal on the upper and lower jaw base and inserting the free end of the buccal multi-curved spring into the corresponding palatine canal. However, the problem that the buccal multi-curved spring corrector is easy to break in a stress concentration area is not solved, and the bending difficulty of the buccal multi-curved spring corrector also increases the labor and time cost for doctors.

Compared with the traditional appliance, the bracket-free invisible appliance has the advantages of beautiful appearance, comfort, contribution to oral hygiene maintenance and the like. Compared with the traditional fixed correction technology, the bracket-free invisible correction technology has the advantages that the correction device is formed by processing medical resin films, and correction devices such as belt rings, brackets, arch wires and the like for fixing the correction device are omitted, so that the bracket-free invisible correction technology is called as a bracket-free technology; the appliance made of the transparent resin film is not easy to be detected when being worn in the mouth, so the appliance is called as invisible.

However, for class iii cross-bite of anderson, compared to the conventional appliance, which can adopt an external force traction device, a buccal multi-curved spring, etc. to assist in correction, the correction is performed by simply relying on the bracket-free invisible orthodontic braces, which is difficult to achieve the predetermined correction target. Due to the limitation of the forming process of the bracket-free invisible orthodontic braces, it is difficult to install devices such as a palatine tube on the bracket-free invisible orthodontic braces, and therefore, it is difficult to organically combine the auxiliary orthodontic devices with the bracket-free invisible orthodontic braces. When the anshi III type malocclusion correction is clinically carried out on the bracket-free invisible correction tooth socket, an inward shift oblique guide surface is usually arranged on the lower jaw invisible tooth socket, and an occlusion body matched with the inward shift oblique guide surface is arranged on the upper jaw invisible tooth socket. When a patient bites naturally, the biting body forms outward thrust on the upper anterior teeth by applying biting force to enable the upper anterior teeth to move towards the labial side, the biting force forms inward thrust on the lower anterior teeth through the lower teeth inward-moving oblique guide surface due to the fact that the top of the lower teeth inward-moving oblique guide surface inclines towards the lingual side, the lower anterior teeth are adducted to move towards the lingual side, and therefore the anterior teeth can be gradually restored to normal occlusion through long-term wearing correction. Although it adopts and does not have the stealthy weakness of correcting the facing in aspects such as treatment course and comfort level of traditional fixed correction, nevertheless can increase and do not have the stealthy degree of difficulty of correcting the facing preparation in support groove, and still exist and correct the shortcoming that efficiency is low night: the patient can not play a role even wearing the appliance at the time when the upper jaw and the lower jaw are separated from occlusion due to the relaxation of muscles around the mouth in the night sleep; growth hormone is secreted vigorously during sleep, which is the golden time period for guiding the growth and development of the jaw bone, and the defects limit the clinical application range and the correction efficiency of the existing invisible correction device.

Furthermore, type II anshi malocclusion is also one of the clinically common malocclusion deformities, with the primary pathogenesis being dysarthria of the sagittal position of the maxilla and/or dentition. The Anshi class II deformity is manifested by underdevelopment of the mandible, with or without overgrowth of the maxilla; during growth and development in children, abnormal occlusion of teeth often occurs with abnormal jaw development, where occlusion interference is a major acquired environmental factor contributing to the aforementioned jaw deformity. For example, the pronation and deep occlusion of the upper incisors can limit mandibular development, causing or aggravating Anshi class II deformities. For the patients, the treatment should be performed at the early stage of the growth and development peak, the occlusion interference is relieved, the growth and development of the upper and lower jaws are guided, and the sagittal position relationship of the upper and lower jaws is coordinated, so that neutral occlusions are established and the lateral appearance is improved. The traditional treatment method is carried out in two steps, wherein the first step adopts a movable appliance or a fixed appliance to relieve occlusion interference, and the second step adopts a functional appliance to guide the growth of the lower jaw and/or inhibit the forward growth of the upper jaw. The treatment method has the defects of long treatment course, poor comfort of the appliance, poor aesthetic degree, poor patient compliance and the like; and the functional appliance has no function of aligning teeth, which is not beneficial to establishing the occlusion of the posterior teeth, thus leading to the unattractive appearance and poor occlusion function of the patient at the stage.

Currently, for type II angler malocclusion patients, various leading mandibular functional appliances are commonly used clinically to improve the relationship between the upper and lower jaws. For example, although the invisible orthodontic device disclosed in chinese utility model with application No. 201320028895.0 and the mandibular guide disclosed in chinese utility model with application No. 201720697007.2 overcome the disadvantages of conventional fixation and correction in terms of treatment course and comfort, the invisible orthodontic device with no bracket still has the disadvantage of low mandibular efficacy at night, because the perioral muscles of the patient can relax during sleep at night to cause the upper and lower jaws to disengage from the occlusion, and at this time, the device cannot function even if worn; growth hormone is exuberant in secretion during sleep, which is the golden time period for guiding the growth and development of the jaw bones, and the defects limit the clinical application range and the correction efficiency of the existing invisible correction device.

The term "occlusal" in this text is a term of professional vocabulary in oral medicine, English is oclusion, and the term "occlusal" is a left part and a right part of a character, and the character cannot be found in a common character library, so that the term "occlusal" is written separately.
