个性化舌侧正畸矫治器的制造方法 The method of manufacturing a personalized orthodontic appliance of lingual

技术领域 Technical Field

本发明涉及用于矫正牙齿的正畸矫治器制造技术,特别是一种个 The present invention relates to a manufacturing technique for orthodontic correction of teeth, particularly a one

体化舌侧正畸矫治器的DLP数码影像投射技术快速成型制造方法。 Body of lingual orthodontic appliance of DLP projection technology in digital imaging method of rapid prototyping. 背景技术 Background

为了将不整齐的牙齿排列整齐,临床应用广泛采用正畸技术。 For the irregular teeth arranged in neat rows, orthodontic technology is widely used in clinical applications. 唇侧多托槽矫治系统经过不断的改进,其外观大小己经基本稳定下来。 Multi-labial bracket appliance systems through continuous improvement, the appearance of size has basically stabilized. 随着成人患者的增多,正畸材料和技术的美观与否已经成为选择托槽系统的重要指标。 With the increase in adult patients, aesthetics orthodontic materials and technologies has become the choice of whether or not an important indicator of the bracket system. 唇侧托槽固定矫治系统尽管进行了小型化托槽、陶瓷或塑料透明质材等方面的改进,但矫治器始终无法真正实现隐形的效果。 Labial bracket fixed appliance system despite improved miniaturization brackets, ceramic or plastic transparent quality materials and so on, but the appliance still can not realize the effect of invisibility. 舌侧矫治器由于托槽和弓丝均粘接在舌侧,应该是最理想的美观矫治器。 Appliance lingual brackets and arch wires due are bonded lingual, should be the best aesthetic appliance. 但是舌侧异物出现对舌体的刺激、对发音的影响以及对具体操作的苛刻要求影响了该矫治器的推广应用。 But the tongue side of tongue foreign body stimulation, and the impact on the pronunciation of the harsh impact of the specific requirements of the operation of the appliance application. 经过近三十年的摸索和改进,舌侧矫治器和矫治技术日趋成熟,形成了独具特色的治疗体系,而对患者日常功能活动的影响也降低到可以容忍和适应的程度。 After nearly three decades of exploration and improvement, lingual appliance and appliance technology matures, the formation of a unique treatment system, and the impact on the patient's activities of daily functions is reduced to the extent that can be tolerated and adaptation. 在我国,由于高收入阶层、演员等特定人群的需要,舌侧矫治技术也逐步推广开来,在各大专院校正畸专科以至个体诊所均开始实施该项技术。 In China, the need for high-income class, actors and other specific groups, lingual orthodontics technology to promote open gradually in the orthodontic specialist tertiary institutions as well as private clinics have begun to implement the technology.

正畸矫治器按其在口腔内固位的方式可分为可摘矫治器和固定矫治器两大类。 Orthodontic appliances according to their retention in the oral cavity can be divided into the removable appliance and fixed appliance two categories. 固定矫治器是标准化生产带有底板并由钢片连接的通用产品,对于不同个体的牙齿而言,适合程度比较低。 Fixed appliance is standardized production with steel plate connected by a universal product for different individual teeth, the appropriate level is relatively low. 因为不同个体 Because different individuals

5牙齿的表面形态存在差异,矫治器底板与牙齿表面的空隙由粘接剂填补。 5 differences in surface morphology of the teeth, the gap appliance chassis with tooth surfaces filled by adhesive. 如果牙齿表面曲率变化较大,则需要的粘接剂较多,造成矫治器底板远离牙表面,使患者感到不舒适,容易松脱,最终影响矫治效果, 而且临床操作难度大。 If the tooth surface curvature changes in the larger, more need of the adhesive, causing the floor away from the tooth surface appliance, so that patients feel comfortable, easy to loose, and ultimately affect the treatment effect, and clinical operations difficult. 可摘矫治器结构简单,可自行摘戴,有利于口腔卫生的维护,但对矫治力的控制不够精确。 Simple removable appliance structure, self-pick to wear, is conducive to the maintenance of oral hygiene, but the treatment was not sufficiently precise force control. 发明内容 DISCLOSURE
