Retrospective study of bracket failure according to mandibular plane angle on party size from ClassⅡ malocclusion patients
교정 치료 중 고정성 교정 장치의 탈락은 치료기간을 길어지게 하고 환자의 불편을 초래한다. 장치 탈락의 요인 중 임상적으로 자주 접할 수 있는 것으로 저작 시 교합에 의한 탈락을 들 수 있다. 교합력의 크기와 얼굴의 수직적 형태가 관련이 있다는 보고가 많이 있었으므로 이에 본 연구에서는 Angle Ⅱ급 부정교합자를 대상으로 하여 안모의 수직적 분류에 따른 고정성 교정장치의 탈락률을 확인하고 관련성을 확인하였다. 서울에 위치한 치과의원에서 4개의 소구치를 발치한 뒤 Clippy-C 브라켓을 이용하여 교정치료가 완료된 124명을 …
