Description

一种定制化舌侧正畸托槽及其制造方法 A side-method of manufacturing the orthodontic bracket customized tongue

技术领域 FIELD

[0001] 本发明涉及口腔牙齿正畸器械技术领域,特别涉及一种舌侧正畸托槽及其制造方法。 [0001] The present invention relates to oral BACKGROUND orthodontic instruments, particularly to a side of an orthodontic bracket and a manufacturing method of the tongue.

背景技术 Background technique

[0002] 正畸是利用矫治弓丝施力于粘接于牙齿上的正畸托槽,将畸形的牙齿排列整齐的过程。 [0002] using an orthodontic archwire applies a force to the orthodontic bracket is bonded to teeth, the teeth in order deformity process. 随着生活水平的提高,人们追求美的需求越来越强烈,越来越多的成人患者也希望能接受正畸治疗,但是常用的唇侧矫治技术需要将托槽粘接于患者牙齿的唇侧面,作为成人患者,由于社交的需要和对美观的高要求,很多患者无法接受佩戴唇侧托槽,舌侧矫治技术的出现很好的解决了这一问题,舌侧矫治技术所使用的托槽不是粘接于牙齿唇侧面,而是粘接于牙齿舌侧面,这样一来就使佩戴者很难被发现正在做正畸治疗。 With the improvement of living standards, people's pursuit of beauty growing demand, more and more adult patients receiving orthodontic treatment also hope, but common labial correction technology necessary to bracket bonding to the labial surface of the patient's teeth as in adult patients, due to the social needs and high demands on aesthetics, many patients can not accept wearing labial side of the bracket, the emergence of lingual orthodontics technology a good solution to this problem, the bracket lingual orthodontics technology used is not bonded to the tooth labial surface, but is bonded to the tongue side of the teeth, such an action would be difficult for the wearer to be found doing orthodontic treatment.

[0003]目前,市面上常见的舌侧托槽大致分为两大类:一种是标准化制作的舌侧托槽,该托槽槽沟中包含的数据,包括牙齿扭转、牙齿转矩、牙齿轴倾等都是基于一定数目的自然正常牙列牙齿的平均数据而设计出来的,即不同患者每个牙位的托槽都使用的同一数据进行矫治,这种标准化的托槽明显会有矫治精度不够和矫治效率不高等问题,并且患者的舒适度是极差的,甚至会影响到发音;另外一种定制化舌侧托槽是根据每个患者的舌侧牙面情况单独的设计托槽的底板,底板的设计一般在计算机中进行,通过牙面数据的偏移组合成一个与牙面吻合的厚薄基本均匀的薄片,然后在虚拟环境中组装上托槽的槽沟和方便结扎的上下翼,最后通过3D打印的方式制造出实体的托槽,这种托槽较标准化制作的舌侧托槽有效的提高了矫治的效率,也一定程度提高了患者 [0003] Currently, common market lingual brackets generally divided into two categories: one is the production of standardized lingual bracket, the bracket slot data contained, including dental twist, torque teeth, tooth axis tilt are all based on the average data of a number of natural and normal dentition tooth designed, i.e. the same data bit of different patients each tooth brackets are used for correction, such standardized treatment will significantly bracket treatment efficiency and lack of precision not high, and the comfort of the patient is very poor, and even affect the pronunciation; another customized lingual brackets is a lingual surface of each patient individually designed brackets the bottom plate, the bottom plate is generally carried out in the design of a computer, and combined into a tooth surface coincide substantially uniform thickness sheet data by shifting the tooth surface, and then assembled on the bracket groove and facilitate ligation vertically in a virtual environment wing, finally producing printed out by means of 3D entities bracket, the bracket more such standardized treatment effectively improves the efficiency of production of the lingual bracket, also to some extent improved the patients 舒适度,至少在绝大多数情况下不会影响到患者发音,但是目前3D打印出来的托槽槽沟精度相对标准化制作的托槽要差一些,误差一般在30 μ m以上。 Comfort, at least in most cases the patient does not affect the pronunciation, but now 3D print accuracy bracket slot groove made relatively standardized brackets to be worse, the error is 30 μ m or more.

[0004] 然而,现有市面上的舌侧托槽仍存在以下缺陷:第一,现有舌侧托槽佩戴舒适度低,现有舌侧托槽均存在或多或少的对舌头的刺激,特别是使用矫治器的前一到两周的适应时间中,患者将会非常的不适应,不但影响到饮食,甚至会影响到睡眠;第二,现有舌侧托槽在牙齿移动过程中对牙齿轴倾的控制效果差,特别是尖牙的轴倾控制,目前舌侧托槽通常是在牵引钩上设计双槽沟,这样制作一方面会使制造的成本大幅度升高,还会明显的减低患者的舒适度和提高医生操作的难度;第三,现有舌侧托槽的矫治效率相对唇侧托槽依然较低,因为在舌侧相对唇侧的牙弓较短,按照现有的设计和生产方式,如果将托槽的槽沟设计过窄,与槽沟配合的弓丝长度也相应的变短,对牙齿的控制也减弱,假如将托槽的槽沟设计过宽,与槽沟配合的弓丝长度会变宽, [0004] However, the conventional commercially lingual bracket still has the following defects: First, the conventional lingual brackets low wearing comfort, stimulation of the tongue more or less conventional lingual brackets are present in particular adaptation time one to two weeks before using the appliance, the patient will be very suited, not only affect the diet, and even affect sleep; second, existing lingual brackets tooth movement in tooth axis tilt control effect is poor, especially canines axis tilt control current lingual brackets are usually designed grooves on the traction hook-slot, it would significantly increase the manufacturing of this aspect of the production cost, but also significant patient comfort and reduce the difficulty of improving the operation of a doctor; third, conventional treatment efficiency lingual bracket opposite labial bracket is still low, because the labial lingual arch opposite short, according to current some design and production methods, if the groove is too narrow bracket design, and mating groove archwire length becomes short accordingly, control of the teeth is also reduced, if the groove is too wide design of the bracket, cooperating with the archwire slot length is broadened, 是托槽与托槽之间弓丝的长度会减小,会使弓丝的弹力大幅度降低,同样会影响矫治的效率;第四,相对于标准化制作的托槽的槽沟精度,定制化舌侧矫治器因为制造工艺水平的原因,槽沟精度依然较低,以成型效率较高的DLP数字光固化快速成型技术来说,投影光在槽沟区域固化时形成的漫反射对槽沟精度有相当大的影响。 Is between the bracket and the bracket archwire slot length may be reduced, will greatly reduce the force of the archwire, will also affect the efficiency of treatment; and a fourth, with respect to the accuracy of the groove of the bracket of a standardized production, customization lingual orthodontics reasons from the manufacturing technology level, the groove is still low precision, with high molding efficiency DLP digital technology stereolithography, the diffuse reflection of the projected light at the groove formed region accuracy curing of the grooves have a considerable impact. 另外假如采用挑选制作的方式制作,又会提高生产成本和加长生产周期。 Further, if the selection made by way of production, would increase production costs and longer production cycle.
