Abstract

Recent developments in software technology have made it possible to create a virtual three-dimensional model of the dental arches from digitally scanned casts of a patient's dentition. This modelmay then be manipulated with software to produce stages of tooth movement from the initial malocclusion to the final desired occlusion. A sterolithograghic model is made for each stage of tooth movement which is the basis for construction of a series of clear and thin overlay appliances. These appliances are worn full time by the patient to move the teeth according to the programmed stages of movement. Malocclusions involving mild to moderate crowding and space closure have been proven to be successfully treated with this appliance. Experience with this appliance has demonstrated excellent patient compliance with less discomfort, improved esthetics and oral hygiene control, when compared with fixed orthodontic appliances. Orthodontic treatment with this appliance is a potentially useful alternative approach to fixed appliances for treatment of a variety of malocclusions in patients with fully erupted permanent teeth.

최근 컴퓨터 소프트웨어의 발전으로 환자의 모형을 scanning하여 3차원 가상 모델을 만드는 것이 가능하게 되었다. 이러한 모델은 컴퓨터로 처리되어 치료 시작부터 끝까지 여러 단계의 치아 이동이 이루어지고, 치아 이동의 각 단계별로 stereolithographic model이 만들어 지는데, 이는 일련의 투명하고 얇은 overlay 장치를 제작하는 기초가 된다. 계획된 치아 이동의 단계에 따라 치아를 움직이기 위해서는 환자가 장치를 항상 사용해야 하며, 중정도의 crowding과 공간 폐쇄는 이 장치로 치료가 용이하다는 것이 입증되었다. 지금까지 이 장치를 경험해 본 결과, 고정성 교정장치에 비해 환자가 불편을 덜 느끼고 심미성과 구강 청결이 좋아 환자의 협조도가 뛰어 났다. 이 장치는 완전히 맹출된 영구치열 환자에서 부정교합에 대한 또 하나의 유용한 접근법이라 할 수 있다.
