背景技术Background technique
口腔正畸治疗通过使牙齿发生生理性移动来矫正各种错牙合畸形，治疗目标为协调牙齿咬合，协调牙齿与颌面部软硬组织之间的位置关系，以改善口颌面部的健康、美观和功能。前牙覆牙合是牙齿咬合的主要指标之一，与咬合建立、颌骨发育和面部美观有重要关联。上前牙切缘盖过下前牙牙冠长度1/3以上，被称为深覆牙合，是临床常见的错牙合畸形，伴有上切牙舌倾的称为内倾型深覆牙合。深覆牙合主要表现为上颌和/或下颌前牙伸长，下颌前牙切缘咬在上颌前牙的牙冠颈1/3处，甚至咬在上颌舌侧牙龈，导致下切牙过度磨耗、上颌牙龈创伤，内倾型深覆牙合限制下颌矢状向发育、影响颞下颌关节健康。对于该类患者，正畸治疗需压低前牙，打开前牙咬合，建立正常的前牙覆牙合。Orthodontic treatment corrects various malocclusions by making the teeth move physiologically. The treatment goal is to coordinate the occlusion of the teeth and coordinate the positional relationship between the teeth and the soft and hard tissues of the maxillofacial region, so as to improve the health of the oral and maxillofacial region. , beauty and functionality. Anterior overbite is one of the main indicators of dental occlusion, which is closely related to occlusal establishment, jaw development and facial aesthetics. The incisal edge of the upper anterior teeth covers more than 1/3 of the length of the lower anterior teeth crown, which is called deep overbite, which is a common clinical malocclusion deformity. . Deep overbite is mainly manifested by the elongation of the maxillary and/or mandibular anterior teeth, the incisal edge of the mandibular anterior teeth bites at 1/3 of the crown neck of the maxillary anterior teeth, or even bites on the maxillary lingual gums, resulting in excessive wear of the mandibular incisors, Maxillary gingival trauma, introverted deep overbite restricts the sagittal development of the mandible and affects the health of the temporomandibular joint. For such patients, orthodontic treatment needs to lower the anterior teeth, open the anterior occlusion, and establish a normal anterior overbite.
常用的治疗方法是采用固定矫治，矫治器由托槽和钢丝组成，矫治器美观度和舒适度差，疗程长达一年以上，很多患者由于矫治器长期妨碍美观而放弃治疗。近年来，无托槽隐形矫治技术给口腔正畸治疗提供了新的选择，现有的隐形矫治器由分别覆盖上下颌牙列的透明牙套和粘接于牙面上的附件组成，通过透明牙套对牙面和/或附件的推挤力来实现牙齿的移动。无托槽隐形矫治器具有美观、舒适的优点，然而治疗深覆牙合的矫治效能弱，打开咬合所需疗程长于固定矫治，尤其对于严重深覆牙合的病例，常发生牙齿脱套、咬合打开量不足，导致频繁重启甚至矫治失败。现有技术将隐形牙套和固定矫治器结合起来，提高了打开前牙咬合的效能，但仍具有以下缺陷：1，矫治器设置托槽和辅簧，舒适度较差；2，矫治器就位需分步进行，患者每天多次取戴矫治器需自行安放牙套、安置辅簧，操作困难，难以保证操作准确性和安全性，治疗可控性差。The commonly used treatment method is to use fixed orthodontic treatment. The orthodontic appliance consists of brackets and steel wires. The appliance has poor aesthetics and comfort, and the course of treatment lasts for more than one year. Many patients give up treatment because the appliance has hindered the appearance for a long time. In recent years, bracket-free invisible orthodontic technology has provided a new option for orthodontic treatment. The existing invisible orthodontic appliance consists of transparent braces covering the upper and lower dentition and attachments bonded to the tooth surface. Through the transparent braces Tooth movement is achieved by pushing against the tooth surface and/or attachment. Bracketless invisible appliance has the advantages of beauty and comfort. However, the orthodontic effect for the treatment of deep overbite is weak, and the course of treatment required to open the occlusion is longer than that of fixed orthodontic treatment. Especially for severe overbite cases, tooth detachment and occlusion often occur. The amount of opening is insufficient, resulting in frequent restarts or even failure of correction. The prior art combines invisible braces and fixed appliances to improve the efficiency of opening the occlusion of the anterior teeth, but still has the following defects: 1. The appliance is provided with brackets and auxiliary springs, resulting in poor comfort; 2. The appliance is in place It needs to be carried out step by step, and patients need to place their own braces and auxiliary springs when they take out and wear appliances multiple times a day. The operation is difficult, it is difficult to ensure the accuracy and safety of the operation, and the treatment controllability is poor.
本文中的“牙合”是口腔医学专业词汇，英文为occlusion，牙与合是一个字的左部和右部，在普通字库中找不到该字，故分开书写为“牙合”。In this article, "occlusion" is a professional vocabulary of stomatology. It is occlusion in English. Teeth and occlusion are the left and right parts of a word. This word cannot be found in the ordinary font library, so it is written as "occlusion" separately.

对比例Comparative ratio
固定矫治，矫治器由托槽和钢丝组成，托槽固定于牙面，钢丝的回弹力通过托槽传递给牙齿而使牙齿移动，矫治器美观度和舒适度差，打开咬合阶段的疗程都长达半年以上。Fixed orthodontic treatment. The appliance consists of brackets and steel wires. The brackets are fixed on the tooth surface. The resilience of the steel wire is transmitted to the teeth through the brackets to move the teeth. The aesthetics and comfort of the appliance are poor. for more than half a year.
现有隐形矫治器由分别覆盖上下颌牙列的透明牙套和粘接于牙面上的附件组成，通过透明牙套对牙面和/或附件的推挤力来移动牙齿，隐形矫治器美观舒适度较好，然而打开前牙咬合的矫治效能弱，所需疗程长于固定矫治，常发生牙齿脱套、咬合打开量不足。The existing invisible appliance is composed of transparent braces covering the upper and lower dentition and accessories bonded to the tooth surface respectively. The teeth are moved by the pushing force of the transparent braces on the tooth surface and/or the accessory, and the invisible appliance is aesthetically pleasing and comfortable. However, the orthodontic effect of opening anterior occlusion is weak, and the required course of treatment is longer than that of fixed orthodontic treatment. Teeth dislocation and insufficient occlusal opening often occur.
对33名前牙深覆牙合且不伴有牙列拥挤的患者，分三组分别配戴本发明实施例1和实施例2所述隐形矫治器、固定矫治、现有技术隐形矫治器，在治疗期间让患者进行配戴舒适度评分(评分区间0-10分，0-2分：非常难受，无法忍受；2-4分：难受，尚可忍受；4-6分：无明显不适；6-8分：舒适；8-10分：非常舒适)、配戴美观度评分(评分区间0-10分，0-2分：非常不美观；2-4分：不美观；4-6分：尚可接受；6-8分：美观；8-10分：非常美观)，统计疗程长短(患者完成治疗所需的月数)，并进行疗效评价，其中疗效评价项目为前牙覆牙合改善量(测量前牙覆牙合，计算治疗后比治疗前减小的毫米数，数值越大，说明疗效越好)。统计数据如表1，可见对于该类患者的治疗，该隐形矫治系统除具有舒适度高、美观度好的优点外，较之固定矫治和现有隐形矫治技术，本发明所述隐形矫治器的疗效更好，打开前牙咬合的矫治效能更高。For 33 patients with deep occlusion of anterior teeth and no crowded dentition, they were divided into three groups to wear the invisible appliances described in Examples 1 and 2 of the present invention, fixed appliances, and invisible appliances in the prior art. During the treatment, patients were asked to score the wearing comfort (score range: 0-10 points, 0-2 points: very uncomfortable, unbearable; 2-4 points: uncomfortable, tolerable; 4-6 points: no obvious discomfort; 6 -8 points: comfortable; 8-10 points: very comfortable), wearing aesthetic score (score range 0-10 points, 0-2 points: very unsightly; 2-4 points: unsightly; 4-6 points: Acceptable; 6-8 points: beautiful; 8-10 points: very beautiful), the length of the course of treatment (the number of months required for the patient to complete the treatment), and the efficacy evaluation, the efficacy evaluation item is the improvement of anterior overbite Quantity (measure the overbite of the anterior teeth, calculate the millimeters decreased after treatment compared with before treatment, the larger the value, the better the curative effect). The statistical data are shown in Table 1, it can be seen that for the treatment of this type of patients, the invisible orthodontic system has the advantages of high comfort and good aesthetics. The curative effect is better, and the orthodontic effect of opening the anterior occlusion is higher.
