투명 치아 교정 장치는 얼라이너 또는 상품명 인비절라인(Invisalign) 등으로 불리우며, 얇고 투명한 플라스틱 재질로 형성된 마우스피스 형태로 형성된다. The transparent orthodontic appliance is called an aligner or a trade name of Invisalign, and is formed in the form of a mouthpiece made of a thin and transparent plastic material.
투명 치아 교정 장치는 와이어 및 브라켓을 이용하지 않고도, 치아에 착용되어, 치아를 교정할 수 있고 외관상 좋은 인상을 주므로, 최근 많이 활용되고 있다.Transparent orthodontic devices are worn on teeth without using wires and brackets to correct teeth and give a good appearance, so they have been widely used recently.
한편, 종래에는 투명 치아 교정 장치를 치아에 고정하는 힘을 보강하기 위하여, 치아 표면에 어태치먼트(attachment)를 부착하였다. 여기서, 어태치먼트는 치아 표면에 부착하는 레진 덩어리를 의미한다. 어태치먼트는 투명 치아 교정 장치의 표면의 언더컷(undercut)으로 형성되는 고정홈에 고정될 수 있다.On the other hand, conventionally, in order to reinforce the force for fixing the transparent orthodontic appliance to the teeth, an attachment was attached to the tooth surface. Here, the attachment refers to a lump of resin attached to the tooth surface. The attachment may be fixed to a fixing groove formed by an undercut of the surface of the transparent orthodontic appliance.
그런데, 종래의 투명 치아 교정 장치는 진공 성형으로 제조됨에 따라, 고정홈이 어태치 먼트에 대응하는 형태로 형성하기 어려웠다. 따라서, 종래의 방식으로 제조된 투명 치아 교정 장치는 고정홈과 어태치먼트 간의 치수 오차가 발생함에 따라, 고정홈과 어태치먼트 간의 고정력이 저하되는 문제점이 있었다.However, since the conventional transparent orthodontic appliance is manufactured by vacuum molding, it is difficult to form a fixing groove in a shape corresponding to the attachment. Therefore, the transparent orthodontic device manufactured by the conventional method has a problem in that the fixing force between the fixing groove and the attachment decreases as a dimensional error occurs between the fixing groove and the attachment.
