Description
Technical Field
The utility model belongs to the technical field of the oral medicine, especially, relate to a ware is rescued in stealthy.
Background
Malocclusion deformity is the deformity of teeth and jaw bone caused by congenital genetic factors and/or acquired environmental factors in the growth and development process of children, which is manifested as irregular teeth, facial deformity and the like and harms the health, beauty and function of patients. The facet type II and mild type III malocclusion are clinically common malocclusion deformities, and the main pathogenesis of the malocclusion deformities is the abnormal sagittal position relationship of the upper and lower jaws and/or the dentition. Wherein the maxillofacial type II deformity is manifested by underdevelopment of the mandible, with or without overgrowth of the maxilla; mild class III malocclusion deformities are characterized by mild class III relationships of molar teeth, often accompanied by anterior contra-occlusions, with or without mild irregularities in the sagittal position 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 facet type II deformities; the incisor crossbite may force the mandible to advance, causing or aggravating class III malocclusion 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. 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. The prior art of the mandibular leading device CN201320028895.0 and the invisible correcting device CN201720697007.2 overcomes the weaknesses of the traditional fixed correction in the aspects of treatment course, comfort and the like, but still has the following defects: 1, the clinical application range is limited, the traditional Chinese medicine is only suitable for type II and bone-surface type II malocclusion deformity, and the type III malocclusion deformity cannot be treated; 2, the growth of the maxilla cannot be controlled, and in the case of cases with the overgrowth trend of the maxilla in the vertical direction and/or the sagittal direction, the lack of the growth control of the maxilla can obviously influence the curative effect and even cause the treatment failure; 3, the efficiency of depressing the anterior open bite is lower, and the treatment period is longer for the case with deep occlusion; 4, the efficacy of leading the lower jaw at night is low, so that the upper jaw and the lower jaw are separated from occlusion due to the relaxation of muscles around the mouth of a patient during sleep at night, and the function cannot be realized even if the patient wears the appliance; growth hormone is secreted vigorously during sleep, and it is the golden time period for guiding the growth and development of jaw bones. These deficiencies limit the clinical applicability and the efficacy of existing invisible orthosis devices.
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.

Statistical data is as table 1, and it is visible to this type of patient's treatment, and this stealthy ware of rescaling except having the advantage that the comfort level is high, pleasing to the eye degree is good, rescues and current stealthy technique of rescaling than the tradition, the curative effect of stealthy ware of rescaling is better, opens the efficiency of rescaling of anterior teeth interlock higher to it is long when shortening the treatment course to show.
TABLE 1
27 patients with maxilla type II malocclusion with the vertical and/or sagittal overgrowth tendency are divided into three groups and respectively adopt the invisible appliance, the traditional appliance and the invisible appliance in the prior art in the three groups, and during the treatment period, the patients are subjected to wearing comfort level scoring (the scoring interval is 0-10 minutes, 0-2 minutes are very uncomfortable and cannot be tolerated, 2-4 minutes are difficult and can be tolerated, 4-6 minutes are no obvious discomfort, 6-8 minutes are comfortable, 8-10 minutes are very comfortable), wearing aesthetic level scoring (the scoring interval is 0-10 minutes, 0-2 minutes are very unattractive, 2-4 minutes are unattractive, 4-6 minutes are acceptable, 6-8 minutes are attractive, 8-10 minutes are very attractive), the length of the treatment period (the number of months required by the patients to finish the treatment) is counted, and evaluating the curative effect, wherein the curative effect evaluation items comprise the sagittal growth coordination improvement amount of the upper and lower jaws (the ANB angle is measured by a head shadow, the degree reduced after treatment compared with the degree before treatment is calculated, the larger the numerical value is, the better the curative effect is shown), the vertical growth coordination improvement amount of the face (the ratio of the height to the overall height under the measurement is calculated, the reduction after treatment compared with the reduction before treatment is a positive value, the increase is a negative value, the larger the positive value is, the better the curative effect is shown), and the growth rotation improvement amount of the lower jaws (the plane angle of the lower jaws is measured, the reduction after treatment compared with the reduction before treatment is a positive value, the increase is. Statistical data is as table 2, and it is visible to this type of patient's treatment, stealthy unscrambler except having the advantage that the comfort level is high, pleasing to the eye degree is good, can have the advantage that the course of treatment is short, perpendicularly to control efficiency height concurrently simultaneously, therefore is showing to be superior to the tradition and rescues and present stealthy technique of rescuring.
