Abstract
The purpose of this study was to investigate the histologic changes in mandibular periodontium during overbite closure for openbite treatment by continuous arch wires and anterior vertical elastics. Two female monkey(Macaca nemestrina) with permanent dentition were used. Posterior bite block was fixed to each of their maxillae, which made the animal temporary anterior openbite as well as stabilized the whole maxillary anchorage. In each mandible, all the teeth except the second molars which had been extracted, were prepared for cast crowns. 018 inch Standard brackets were welded on these crowns. After cementation, two types of the
본 연구는 영구치열이 완성된 원숭이 2마리를 실험 동물로 선정하여 전치간 수직 고무와 연속 호선에 의한 개교 치료 기전으로 수직피개도가 증가하였을 때, 하악 치주 조직의 조직학적 변화를 고찰하였다. 상악에 구치부 교합거상판을 장착시켜 일시적인 전치부 개교 상태를 유발하면서 상악을 고정원으로 안정화하였고, 하악에는 양측 제2대구치를 발거한 후 나머지 모든 치아에 주조금관을 제작하였다. 각 주조금관에 018inch 표준 브라켓을 납착하여 구내 고정하고, 대조동물에는
