Abstract
병적 치아 이동된 상악 전치를 가진 중등도 치주염 환자에서는 치태 관리를 통한 치주 염증의 해소뿐만 아니라 치아를 재위치 시키기 위한 교정치료가 함께 필요하다. 이 때의 교정치료는 더 적은 힘의 적용과 치아의 저항중심, 최적의 힘 등을 세심하게 고려해야 하는데, 이동하고자 하는 치아에만 적용되는 분절호선은 이동의 예측성을 높여주고, 힘을 조절할 수 있어 보다 효율적이다. 또한 교정치료 시, 고정원으로 사용되는 치아의 원치 않는 움직임을 차단하여 구치 교합 상태를 유지할 수 있는 장치 설계가 필요하며, 이를 위해 다양한 종류의 골성 고정원이 사용될 수 있다. 본 증례에서는 정출되고 변위된 상악 전치를 가진 환자에서, 철저한 치주 치료와 적절한 힘과 역학이 설계된 교정 장치로, 양호한 치료 결과를 얻을 수 있었으므로, 소개하고자 한다.
Patients who have a moderate periodontitis with pathologic tooth migration of maxillary incisors, it is necessary not only periodontal treatment for reduce periodontal inflammation, but also orthodontic treatment to teeth repositioning. For orthodontic treatment, it is necessary to apply less force and careful considerations of the center of resistance of the tooth and optimal force of tooth movement. At this time, the segmental arch applied only to the target teeth, is more effective and predictable, because applied force and direction can be controlled. In addition, to design the orthodontic appliance that can prevent the unwanted tooth movement that used as an anchorage is important. In recent years, various types of skeletal anchorage system have been used for preventing loss of the anchorage. We reported the patient who had extruded maxillary central incisor due to pathologic tooth migration, treated by a successful periodontal-orthodontic multidisciplinary treatment using an orthodontic appliance designed to apply less traumatic force and reduce an anchorage loss.
