项目摘要

This study intended to provide the three-dimensional tongue posture image to the children with occlusal and articulatory disorder in their own facial and dentitional image, furthermore, to show their tongue movement from the rest position to the swallowing position as an animation, in order to increase their motivation for the treatment and to prompt their behavior modification. At the 1^<st> year of the study, we developed the software that the images of upper and lower dental models which were projected separately from the white-lights-gratings project-type three-dimensional measurement device (GRASP-M, Technoarts Lab. Co.) were combined with the 3 common measurement points. We also refined both the hardware and the software of the face measurement section in the same device (GRASP-F) to get the information more quickly and steadily even from the small children.At the 2^<nd> year, we developed the software that integrated the images of both occluded models and face by lying the cephalometric profile and teeth images between them. Because the anterior one-third of the tongue image could not be observed clearly by the ultra-sonography, we got the impression of the tongue dorsum from one of our study colleagues both at the resting position and the swallowing position and made their models. The three-dimensional images of tongue dorsums by the GRASP-M were fitted into the integrated facial and dentitional image. On the other hand, the tongue dorsum movement both at the frontal section (upper first molar's mesial points) and mid-sagittal section from the sonography were drawn in the series using time as t direction and made them as the fundamental information for the tongue movement animation. However, we still could not get the animation even at the final month of the academic years, and remained the task for another year.

本研究旨在为患有咬合和关节障碍的儿童提供其面部和牙列图像中的三维舌头姿势图像，并以动画形式展示他们的舌头从休息位置到吞咽位置的运动，以增加他们的治疗动机并促使他们改变行为。在研究的第一年，我们开发了将白光光栅投影式三维测量装置（GRASP-M，Technoarts Lab. Co.）分别投影的上下牙齿模型图像与3个公共测量点相结合的软件。我们还在同一设备（GRASP-F）中改进了面部测量部分的硬件和软件，以便即使是小孩子也能更快、更稳定地获取信息。第二年，我们开发了通过将头影测量轮廓和牙齿图像放置在咬合模型和面部图像之间来集成咬合模型和面部图像的软件。由于超声检查无法清楚地观察到舌前三分之一的图像，因此我们从一位研究同事那里获得了舌背在静息位和吞咽位时的印象并制作了模型。 GRASP-M 的舌背三维图像被拟合到集成的面部和牙列图像中。另一方面，以时间为t方向，连续绘制了超声检查中额叶面（上第一磨牙近中点）和中矢状面的舌背运动，并将其作为舌运动动画的基础信息。然而，到了学年的最后一个月，我们仍然没有得到动画，这个任务又拖到了一年。
