定制牙托膜片切牙区厚度变化的影响因素
Factors affecting the variation of incisor sheet thickness of a custom-made mouthguard during fabrication

摘要： 佩戴运动牙托可以缓冲外力,降低颌面部损伤的风险。运动牙托种类较多,其中个性化定制运动牙托具有较好的保护作用和较高的舒适度而备受欢迎。个性化定制运动牙托的膜片加热后可发生延展,随后发生厚度变化,尤以切牙区膜片的厚度变化更能影响其保护性能;因此,笔者就影响个性化定制运动牙托膜片切牙区的厚度变化的膜片硬度、膜片形状和膜片表面设计等膜片因素,工作模厚度和工作模摆放角度等工作模因素,加压方法,夹持托盘形状、夹持方式和夹持托盘与工作模底座的距离等夹持因素,加压时间等的研究进展作一综述。
Abstract: A mouthguard is a protective device that can buffer impact force and reduce the risk of maxillofacial trauma. A custom-made mouthguard enjoys great popularity owing to its superior comfort and stress dispersion effect. A mouthguard sheet is heated, then becomes soft, and stretches during fabrication; this process makes the mouthguard thinner and less effective. Accordingly, we will make a brief review of the factors(including hardness, shape, and surface design of sheets; thickness and position angle of work model; laminating methods; and shape of holding tray, holding condition, and distance between holding tray and work model) that affect the thickness variation of the incisal region of a custom-made mouthguard.
