Description
技术领域technical field
本发明属于口腔医学技术领域，尤其涉及一种下颌前导隐形矫治器。The invention belongs to the technical field of stomatology, and in particular relates to a mandibular leading invisible appliance.
背景技术Background technique
错牙合畸形是由先天或后天环境因素导致的牙齿、颌骨、颅面的畸形，给患者的颜面美观、口颌功能和身心建康带来严重危害。安氏II类错牙合是临床常见的错颌畸形，其主要发病机制为上颌磨牙前移、上下颌骨矢状向位置关系不调。此类患者的磨牙为远中关系，常有下颌骨发育不足。除颌骨发育异常外，往往还伴有多种其他牙列问题，如牙弓宽度不调，牙列拥挤等症状。其中，上牙弓狭窄、尤其后牙段牙弓宽度不足会限制下颌向前生长，成为与颌骨畸形相辅相成的咬合干扰。对于该类患者，应在生长发育高峰前期进行治疗干预，解除咬合干扰，引导颌骨发育从而改善上下颌骨位置关系，有利于建立中性牙合和改善侧貌面型。传统的治疗方法是采用双期矫治，一期治疗应用功能矫治器引导下颌向前生长，二期固定矫治器排齐牙列，精细调整咬合关系。上述双期矫治常长达两年以上，存在疗程长、矫治器不美观、舒适度差、患者依从性不佳等缺点；并且功能矫治器不能排齐牙列，不利于建立后牙咬合，影响患者在该阶段的咬合功能和颜貌美观。Malocclusion is a deformity of teeth, jaws and craniofacial caused by congenital or acquired environmental factors, which brings serious harm to the patient's facial beauty, oral and jaw function, and physical and mental health. Class II malocclusion is a common clinical malocclusion, and its main pathogenesis is that the maxillary molars are moved forward and the sagittal position of the maxilla and mandible is not adjusted. The molars of such patients are distal, and the mandible is often underdeveloped. In addition to abnormal jaw development, it is often accompanied by a variety of other dentition problems, such as irregular dental arch width, crowded dentition and other symptoms. Among them, the narrow upper dental arch, especially the insufficient width of the posterior dental arch, will restrict the forward growth of the mandible and become an occlusal interference that complements the jaw deformity. For such patients, treatment intervention should be carried out in the early stage of growth and development to relieve occlusal interference, guide the development of the jaws to improve the positional relationship of the upper and lower jaws, and help to establish a neutral occlusion and improve the profile. The traditional treatment method is to use two-stage treatment. The first-stage treatment uses functional appliances to guide the forward growth of the mandible, and the second-stage fixed appliances align the teeth and finely adjust the occlusal relationship. The above-mentioned dual-stage orthodontic treatment usually lasts for more than two years, and has disadvantages such as long course of treatment, unsightly appliance, poor comfort, and poor patient compliance; and the functional appliance cannot align the dentition, which is not conducive to the establishment of posterior occlusion, affecting the The patient's occlusal function and aesthetic appearance at this stage.
近年来，无托槽隐形矫治技术将透明牙套用于口腔正畸治疗，克服了传统固定矫治在美观度和舒适度方面的弱点。现有技术“下颌前导器CN201320028895.0”提供了一种用于前导下颌的隐形矫治装置，但存在以下缺陷：1，夜间前导下颌的效能低，患者在夜间睡眠中由于升颌肌群松弛导致上下颌脱离咬合，此时即使配戴了矫治器也无法前导下颌；而夜间生长激素分泌旺盛，正是颌骨生长发育的黄金时段；2，对牙弓的横向控制效能较弱，矫正牙弓宽度的效能不足，对于上牙弓宽度不足的病例疗程较长；现有技术“一种隐形矫治装置(201720697007.2)”未改进对牙弓的横向控制效能，不能保证夜间下颌处于前导位置，而且其特殊结构的引导面在下颌咬合功能运动中会带来咬合干扰。这些不足限制了现有隐形矫治器的矫治效能和临床适用范围。In recent years, bracket-free invisible orthodontic technology uses transparent braces for orthodontic treatment, overcoming the shortcomings of traditional fixed orthodontics in terms of aesthetics and comfort. The prior art "mandibular lead device CN201320028895.0" provides an invisible orthodontic device for leading the mandible, but has the following defects: 1. The efficiency of leading the mandible at night is low, and the patient sleeps at night due to the relaxation of the maxillary muscles. The upper and lower jaws are out of occlusion, and the lower jaw cannot be brought forward even if the appliance is worn at this time; and the strong secretion of growth hormone at night is the golden period for the growth and development of the jaw; 2, the lateral control of the dental arch is weak, and the dental arch is corrected. The efficacy of width is insufficient, and the treatment course is longer for cases with insufficient width of the upper dental arch; the prior art "An invisible orthodontic device (201720697007.2)" does not improve the lateral control performance of the dental arch, cannot ensure that the mandible is in the leading position at night, and its The special structure of the guiding surface can cause occlusal interference in the movement of the mandibular occlusal function. These deficiencies limit the orthodontic efficacy and clinical application scope of existing invisible appliances.
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.

具体实施方式Detailed ways
以下通过特定的具体实例说明本发明的实施方式，本领域技术人员可由本说明书所揭露的内容轻易地了解本发明的其他优点与功效。本发明还可以通过另外不同的具体实施方式加以实施或应用，本说明书中的各项细节也可以基于不同观点与应用，在没有背离本发明的精神下进行各种修饰或改变。The embodiments of the present invention are described below through specific specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

对比例Comparative ratio
双期矫治采用两种矫治器，一期矫治采用功能矫治器引导下颌向前生长，功能矫治器由树脂基托和钢丝制成，树脂基托包裹部分钢丝并覆盖口腔黏膜，钢丝弯制形成卡环等固位结构和唇弓、诱导丝等功能结构。二期矫治采用固定矫治器排齐牙列，精细调整咬合关系。上述双期矫治常长达两年以上，疗程长、矫治器美观度和舒适度差、患者依从性不佳。Two-stage orthodontic treatment uses two kinds of appliances. In the first-stage treatment, a functional appliance is used to guide the forward growth of the mandible. The functional appliance is made of resin base and steel wire. The resin base wraps part of the steel wire and covers the oral mucosa, and the steel wire is bent to form a card. Retention structures such as rings and functional structures such as labial arches and induced filaments. The second-stage orthodontic treatment uses fixed appliances to align the dentition and finely adjust the occlusal relationship. The above-mentioned two-stage orthodontic treatment usually lasts for more than two years, with a long course of treatment, poor aesthetics and comfort of the appliance, and poor patient compliance.
现有技术中的隐形矫治器由三维矫治牙套、下颌前导斜面牙合垫和前牙压低辅助导板组成，具有美观、舒适等优点，同时具有牙弓横向控制效能较弱、对牙弓宽度的矫治效能不足、夜间前导下颌的效能低等缺陷。The invisible appliance in the prior art is composed of a three-dimensional orthodontic brace, an anterior mandibular bevel occlusal pad, and an anterior tooth depression auxiliary guide plate, which has the advantages of beauty and comfort, and has the advantages of weak lateral control of the dental arch and orthodontic treatment of the width of the dental arch. Defects such as insufficient potency and low potency of the leading jaw at night.
对33名下颌发育不足、伴有上后牙区宽度不足的安氏II类错牙合畸形患者，分三组分别配戴本发明实施例1所述隐形矫治器、双期矫治、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，其中疗效评价项目包括下颌矢状向位置改善量(头影测量ANB角，计算治疗后比治疗前减小的度数，数值越大，说明疗效越好)、上磨牙区宽度改善量(测量上颌第一磨牙间宽度，计算治疗后比治疗前增加的毫米数，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，该隐形矫治器兼有舒适度高、美观度好的优点外，较之双期矫治和现有隐形矫治技术，本发明所述隐形矫治器矫治牙弓宽度的效能更高，前导下颌的疗效更好、效率更高。Thirty-three patients with Angel's Class II malocclusion with insufficient mandibular development and insufficient width of the upper and posterior teeth were divided into three groups to wear the invisible appliance described in Example 1 of the present invention, dual-stage orthodontic treatment, and prior art. Invisible aligners, during the treatment, the 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, among which the efficacy evaluation items include the mandible Sagittal position improvement (cephalometric measurement of ANB angle, calculate the degree of reduction after treatment compared with before treatment, the larger the value, the better the curative effect), the improvement of the width of the upper molar region (measure the width between the maxillary first molars, calculate The number of millimeters increased after treatment compared with before treatment, the larger the value, the better the effect). Statistical data are shown in Table 1. It can be seen that for the treatment of this type of patient, the invisible appliance has the advantages of high comfort and good aesthetics. The efficacy of correcting the width of the dental arch is higher, and the efficacy and efficiency of the leading mandible are better.
