In general, during orthodontic treatment, the patient's current dental condition is scanned to create a three-dimensionally reproduced digital dental model on a computer, and then a digital setup model is used to cut out individual teeth and arrange them in an optimal position.
디지털 셋업모형을 제작하는 종래의 방법은 컴퓨터 모니터 상에서 개개의 치아들을 배열할때 시술자의 눈대중에 의하여 보기좋게 배열하는 것으로서, 시술자의 감각에 의존하는 수 밖에 없기 때문에 상당한 시간이 걸리고, 배열의 정확성이 떨어진다.The conventional method of fabricating the digital setup model is to arrange the individual teeth on the computer monitor by the operator's eyes, and it takes a considerable time because it depends only on the operator's senses. Falls.
디지털 셋업모형을 제작하는 또 다른 방법으로는 컴퓨터 상에서 개개 치아의 순측면에 정중앙선을 그리고 그 중점을 표시한 후(임상치관중점), 각각의 중점에서 치아순면에 대한 접선을 구한 다음 이를 기준으로 치아들이 자동적으로 이상적인 위치에 배열되도록 하는 방법도 있으나, 치관중점을 정하는 과정에서 시간도 많이 걸리고 상당한 오차가 발생하며, 이런 방법으로 치아들을 배열한 이후에도 개개 치아의 형태 차이에 따른 편차를 시술자가 일일이 수작업으로 수정해 주어야 함으로 부가적인 시간이 또 다시 요구되는 등의 문제가 있었다. Another method of creating a digital setup model is to draw a median line on the labial side of each tooth on the computer, mark its midpoint (clinical focus point), and then determine the tangent to the labial plane at each midpoint. Although there is a method of automatically arranging the teeth in the ideal position, it takes a lot of time and significant errors in the process of determining the center point of the crown, and even after arranging the teeth in this way, the operator is responsible for the deviation of the individual teeth. There was a problem that additional time was required again because of manual modifications.

For example, in the case of the maxilla, the mean slope of the apical inclination angle (A) is the same as in FIG. The first slope of the first molar and the second molar is about -9 °, and the mean slope of the basal sloping angle (B) is about 5 ° for the saddle tooth, and about 5 for the first and second molar as shown in FIG. Maintaining the inclined state by °, as described above, based on the average value of the inclination of each tooth vertical grid plate 30 is designed on the horizontal grid plate (20).
수직격자판의 순설측 경사각과 근원심 경사각은 개개 환자의 치아 형태 차이에 맞게 조절할 수 있으며, 시술자의 교정치료 계획에 의해서도 조절할 수 있다. The apical inclination angle and myocardial inclination angle of the vertical lattice plate can be adjusted according to the tooth shape difference of each patient and can also be adjusted by the operator's orthodontic treatment plan.
여러 수직 격자판 사이의 간격은 이상적으로 배열된 치아들의 평균적 치관장축간 거리에 맞추어 배열하게 된다. 따라서 치관의 근원심 폭경이 큰 치아들의 경우 수직 격자판 사이의 간격이 넓어지며 치관의 근원심 폭경이 작은 치아들의 경우 격자판 사이의 간격이 줄어들게 된다. 수직 격자판 사이의 간격은 개개 환자의 평균적인 치아크기에 따라 조절할 수 있으며 시술자의 치료계획에 따른 필요에 의해서도 조절할 수 있다. The spacing between the various vertical gratings is aligned with the average coronal distance of the ideally arranged teeth. Therefore, in the case of teeth having a large mesial core diameter of the crown, the spacing between the vertical gratings is widened, and in the case of teeth having a small mesial core width of the crown, the spacing between the gratings is reduced. The spacing between the vertical gratings can be adjusted according to the average tooth size of the individual patient and also according to the needs of the operator's treatment plan.
