一种正畸活动矫治器固位装置的设计方法Design method of a retaining device for orthodontic movable appliances

技术领域technical field

本发明属于牙齿正畸技术领域，具体涉及一种正畸活动矫治器固位装置的设计方法。The invention belongs to the technical field of orthodontics, and in particular relates to a design method of a retaining device for an orthodontic movable appliance.

背景技术Background technique

口腔正畸学(orthodontics)是口腔医学的一个分支学科，它的学科内容是研究错颌畸形(malocclusion)的病因机制，诊断分析及其预防和矫治。错颌畸形是指儿童在生长发育过程中，由先天的遗传因素或后天的环境因素，如疾病，口腔不良习惯，替牙异常等导致的牙齿，颌骨，颅面的畸形，如牙齿排列不齐，上下牙弓间的颌关系异常，颌骨大小形态位置异常等。这些异常机制是牙量与骨量，牙齿与颌骨，上下牙弓。上下颌骨，颌骨与颅面之间的不协调。因而近代错颌畸形的概念已远不只是指牙齿错位和排列不齐，而是指由牙颌，颅面间关系不调而引起的各种畸形。世界卫生组织(WHO)把错颌畸形定为“牙面异常”(handicapping dentofacial anomaly)，不但影响外貌同时也影响功能。Orthodontics (orthodontics) is a branch of stomatology. Its subject content is to study the etiology, diagnosis, analysis, prevention and correction of malocclusion. Malocclusion refers to the deformity of teeth, jaw, and craniofacial caused by congenital genetic factors or acquired environmental factors, such as diseases, bad oral habits, abnormal tooth replacement, etc. during the growth and development of children, such as improper arrangement of teeth. Alignment, abnormal jaw relationship between the upper and lower dental arches, abnormal size, shape, and position of the jaw bone, etc. These abnormal mechanisms are tooth mass and bone mass, tooth and jaw, upper and lower dental arches. Incongruity between the upper and lower jaw, jaw and craniofacial. Therefore, the concept of modern malocclusion is far from just referring to misalignment and misalignment of teeth, but refers to various deformities caused by the relationship between jaw and craniofacial. The World Health Organization (WHO) defines malocclusion as "handicapping dentofacial anomaly", which not only affects the appearance but also affects the function.

活动矫治器(removable appliances)是一种纠正牙颌畸形的矫治装置，可由患者或医生自由摘戴，摘下时该矫治器完整无损；它与牙冠和口腔粘膜表面有接触关系。医生根据矫治进展的需要可在矫治器上随意增减那些能产生矫治力的附件，以便达到矫正错合的目的。正畸矫治器的固位是指矫治器能稳固地戴在口内，不会因其本身的重力、矫治力和肌肉功能力等因素而发生脱位。只有活动矫治器固位良好，才能使矫治器发挥其矫治力的作用。Removable appliances are an orthodontic device for correcting dental and jaw deformities, which can be removed and worn by patients or doctors freely. According to the needs of the progress of the correction, the doctor can add or remove the attachments that can generate the correction force on the appliance at will, so as to achieve the purpose of correcting the malocclusion. The retention of orthodontic appliances means that the appliance can be firmly worn in the mouth without dislocation due to factors such as its own gravity, orthodontic force, and muscle function. Only when the removable appliance is well-retained can the appliance play its role in correcting force.

目前常见的固位方法有卡环法；邻间钩法；基托组织面衬垫法及活动矫治器直接粘接在患者牙列上At present, the common retention methods include snap ring method; interproximal hook method; base tissue surface lining method and removable appliance directly bonded to the patient's dentition

但是常规的固位设计在临床应用中存在一些问题：However, the conventional retention design has some problems in clinical application:

其一，对于牙齿形态异常，无倒凹或者倒凹不足的患者固位差，效果不佳。First, for patients with abnormal tooth shape, no undercut or insufficient undercut, the retention is poor and the effect is not good.

其二，乳牙列牙齿形态与恒牙相比牙冠短小，倒凹不明显，因此乳牙列患者固位差，矫治效果不佳；Second, compared with the permanent teeth, the tooth shape of the deciduous dentition is shorter and the crown is smaller, and the undercut is not obvious, so the retention of the deciduous dentition is poor, and the orthodontic effect is not good;

其三，活动矫治器与牙齿粘接固定的方法，由于患者自己不能摘戴，不能洗刷矫治器，因此不能保持矫治器清洁和口腔卫生。而且影响患者的美观。Its three, the fixed method of removable aligner and tooth bonding, because patient oneself can't take off and wear, can't wash aligner, therefore can't keep aligner clean and oral hygiene. And affect the appearance of the patient.

发明内容Contents of the invention

为了克服上述现有技术的不足，本发明的目的在于提供了一种正畸活动矫治器固位装置的设计方法，具有操作简单，不需要弯制各种固位曲；固位附件小巧，患者佩戴舒适；固位效果好，不受牙齿形态的限制，同时乳牙列适用，能够提供足够的固位力；患者能够自由的摘戴，不影响美观的特点。In order to overcome the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a design method of a retaining device for orthodontic movable appliances, which has the advantages of simple operation and no need to bend various retaining curves; the retaining accessories are small and exquisite, and the patient can easily It is comfortable to wear; the retention effect is good, and it is not limited by the shape of the teeth. At the same time, it is suitable for the deciduous dentition and can provide sufficient retention force; the patient can freely remove and wear it without affecting the aesthetic characteristics.

为了实现上述目的，本发明采用的技术方案是：一种正畸活动矫治器固位装置的设计方法，包括如下步骤：In order to achieve the above object, the technical solution adopted in the present invention is: a design method of an orthodontic removable appliance retaining device, comprising the following steps:

第一，在牙齿上准备固位附件，具体做法是：在口内牙齿上用补牙树脂材料制作长1～2mm，宽1～2mm，高0.5～1mm的固位附件；First, prepare the retention attachments on the teeth. The specific method is: use filling resin materials on the teeth in the mouth to make retention attachments with a length of 1-2 mm, a width of 1-2 mm, and a height of 0.5-1 mm;

第二，翻制口内牙齿石膏模型，具体做法是：首先用牙科硅橡胶材料取口内牙齿印模，然后用石膏在印模上灌制石膏模型；Second, make a gypsum model of the teeth in the mouth. The specific method is: first, take an impression of the teeth in the mouth with dental silicone rubber material, and then use gypsum to pour the plaster model on the impression;

第三，在上步制作的石膏模型上制作活动矫治器，本步骤的具体做法是：Third, make movable appliances on the plaster model made in the previous step. The specific method of this step is:

方法一：用自凝牙托粉和自凝牙托水制作活动矫治器基托，基托覆盖住翻制在石膏模型上的固位附件；Method 1: Use self-curing tray powder and self-curing tray water to make a movable appliance base, and the base covers the retention accessories that are reproduced on the plaster model;

或方法二：用正畸压模保持器高分子材料制作活动矫治器基托，基托覆盖住翻制在石膏模型上的固位附件，此时活动矫治器基托在口内牙齿固位附件的位置形成与固位附件大小一致的凹槽；Or method 2: use the polymer material of the orthodontic die retainer to make the base of the removable appliance, and the base covers the retaining attachment made on the plaster model. The position forms a groove consistent with the size of the retention attachment;

最后，从石膏模型上取下活动矫治器，带入口内，活动矫治器基托上的凹槽与口内牙齿固位附件一起构成类似于暗扣的固位结构，将活动矫治器稳定的固定在牙齿上。Finally, remove the removable appliance from the plaster model and bring it into the mouth. The grooves on the base of the removable appliance and the tooth retention accessories in the mouth together form a retention structure similar to a hidden buckle, and the removable appliance is stably fixed on the on the teeth.

由于本发明采用了在牙齿上设计固位附件；翻制牙齿石膏模型制作活动矫治器的设计方法，具有操作简单，不需要弯制各种固位曲；固位附件小巧，患者佩戴舒适；固位效果好，不受牙齿形态的限制，同时乳牙列适用，能够提供足够的固位力；患者能够自由的摘戴，不影响美观的特点。Since the present invention adopts the design of retaining accessories on the teeth; the design method of turning over the plaster model of teeth to make movable appliances has the advantages of simple operation and does not need to bend various retention curves; the retaining accessories are small and exquisite, and the patient is comfortable to wear; The positioning effect is good, and it is not limited by the shape of the teeth. At the same time, it is suitable for the deciduous dentition and can provide sufficient retention force; the patient can take off and wear it freely without affecting the aesthetic characteristics.
