예시적인 제거가능 치과용 기구는 환자의 치열궁의 복수의 치아를 적어도 부분적으로 둘러싸도록 구성된 기구 몸체를 포함한다. 기구 몸체는 초기 위치에서 치아와 맞물리도록 형상화된 쉘, 및 근심 치간 영역으로부터 쉘의 치은 에지를 따라 원심 치간 영역까지 연장되는 치은 리지를 포함한다. 치은 리지는 제거가능 치과용 기구가 환자에 의해 착용될 때 치아의 최대풍륭부 아래의 치아의 설측 또는 순측 표면과 맞물려 기구 몸체가 치아 상의 접촉점에서 힘 벡터를 인가할 수 있게 하여 치아의 원하는 위치를 향한 치아의 이동을 야기하도록 구성된다. An example removable dental appliance includes an appliance body configured to at least partially surround a plurality of teeth of a dental arch of a patient. The appliance body includes a shell shaped to engage a tooth in an initial position and a gingival ridge extending from a mesial interproximal region along a gingival edge of the shell to a distal interproximal region. The gingival ridge is configured to engage a lingual or labial surface of the tooth below a height of contour of the tooth to enable the appliance body to apply a force vector at a contact point on the tooth to cause movement of the tooth toward a desired position of the tooth when the removable dental appliance is worn by the patient.
