隐适美矫正治疗过程

隐适美矫正治疗过程 the Treatment process about invisalign 隐适美的治疗过程 ———河南精益口腔整理 Treatment begins with a doctor taking x-ray, photographs, a bite registration and polyvinyl siloxane impressions of the patient's teeth and gums. The dentist/orthodontist completes a written evaluation that includes diagnosis and treatment plan.Dental impressions are sent to be scanned to create a digital 3D representation of the patient's teeth. Technicians move the teeth to the desired location with the program Treat, which creates stages between the current and desired teeth positions. Anywhere from six to forty-eight aligners may be needed. Each aligner moves teeth .25 to .33 millimeters. 隐适美矫正治疗前的准备，医生进行X-RAY射线拍片，用高精度的聚乙烯矽氧烷印模材 (polyvinyl siloxane)对患者的牙齿和牙龈进行记录。医生要做一份患者诊断报告和治疗方 案的评估材料。牙印模通过扫描在计算机上呈现出数字3D图像。根据医生好的牙齿矫 正阶段，通过计算机技术，把牙齿矫正的过程在计算上进行移动的还原呈现。根据患者 牙齿情况的不同，可能需要六到四十八个隐适美矫正器。每个矫正器移动牙齿会在0.25到 0.33毫米之间。 A 3D representation of a patient's teeth in the Invisalign software 用隐适美原件呈现的病人3D牙齿图像 A computer graphic representation of the projected teeth movements is provided to the doctor and patient in a software program called ClinCheck for approval or modification before aligners are manufactured. The aligners are modeled using CAD-CAM (computer-aided-design and computer-aided-manufacturing) software and manufactured using a rapid prototyping technique called stereolithography.The molds for the aligners are built in layers using a photo-sensitive liquid resin that cures into a hard plastic when exposed to a laser. The aligners are made from an elastic thermoplastic material that applies pressure to the teeth to move into the aligner's position. Patients that need a tooth rotated or pulled down may have a small tooth-colored composite attachment bonded onto certain teeth. More attachments can make the aligners less aesthetically pleasing.Reproximation, (also called interproximal reduction or IPR and colloquially, filing or drilling), is sometimes used at the contacts between teeth to allow for a better fit. 在隐适美矫正器制作之前，关于牙齿矫正各阶段状况的图像变化会通过名叫ClinCheck的软 件提供给医生和患者，方便医生和患者对方案的修改和审批。隐适美矫正器模型利用了 CAD-CAM(计算机辅助设计和计算机辅助制造)软件，隐适美矫正器的制造里面了一种快 速成型技术，名叫光固化立体造型术(stereolithography, SLA)，也就是现今应用最广泛的3D 打印工艺. 矫正器是由具有弹性的热塑性才亮制成的，可以提供压力迫使牙齿移动到正确的 位置，需要扭转和拉压矫正的患者须有用一个很小的牙齿着色不见粘贴的这个特定的牙齿 上。如果使用太多的附件会使矫正器看起来不美观，Reproximation(又名reduction or IPR and colloquially, filing or drilling)，有时候会用在牙齿之间的链接为了达到更好的矫正效果。 A woman wearing Invisalign 佩戴隐适美的女士 Each aligner is intended to be worn 20 hours a day for two weeks.On average the treatment process takes 13.5 months. Treatment time varies based on the complexity of the planned teeth movements.Refinements may be ordered by the doctor during the treatment process. The aligner is removed for brushing, flossing and eating.Once the treatment period has concluded, the patient is advised to continue wearing a retainer at night for the foreseeable future. 每个隐适美矫正器每天佩戴20个小时左右，持续两周时间。平均治疗过程需要持续十三个 半月。治疗的时间是基于牙齿移动复杂程度的。在治疗的过程中要根据师生的要要求进行调 整。刷牙，使用牙线，还有吃饭的时候要去掉矫治器。一旦治疗的时间结束，我们还是建议 患者在晚上持续佩戴一段时间。 When the Invisalign system was first developed, many of the aligner manufacturing processes were done by hand and computer technicians had to modify each tooth in the computerized model individually. 当首次进行Invisalign隐适美系统的开发，许多的矫治器的制作过程需要手工来完成，计算 机技术人员不得在计算机模型中逐个修改每个牙齿。
