Abstract

This case report describes the treatment of a 23-year, 8-month-old female patient with a Class II malocclusion who showed severe bidentoalveolar protrusion and anterior crowding. The treatment plan consisted of extracting all the first premolars, decrowding and en masse retraction of the upper six anterior teeth and lower anteriors. The upper C-plate placed in the midpalatal area combined with lingual sheath fixtures were used as substitutes for posterior anchorage teeth during upper anterior retraction. Preadjusted brackets (0.022-inch) were used for upper anterior decrowding. A 0.9 mm diameter stainless steel lever-arm soldered to the main arch wire facilitated controlled retraction of upper anteriors. The upper and lower dentition was detailed using a tooth positioner during the finishing stage. Correct overbite and overjet were obtained by decrowding and retraction of the upper six anterior teeth into their proper positions. Use of the C-plate and lingual appliances provided ideal anchorage to enhance the improvement in facial balance. The active treatment period was 19 months. The treatment result was stable 13 months after debonding.

본 증례보고는 심한 양악 치아치조성 전돌과 전치부 치열밀집을 보이는 23세 8개월 여자 환자를 대상으로 한 변형된 형태의 설측 교정치료법인 설측 Biocreative therapy 치료를 소개하고자 한다. 양악 제1소구치 발치 후 구개천장에 식립된 C-플래이트에 lingual sheath가 달린 보조장치를 접착하여 상악구치부에 장치부착 없이 튜브역할을 대신하게 하였으며 상악 전치부의 decrowding과 견인을 위하여 설측 교정용 브라켓을 사용하지 않고 0.022 슬롯을 가진 순측 브라켓을 치아 설면에 부착한 후 납착된 설측 레버암을 이용하여 상악 전치부의 3차원적인 견인을 시행하였으며, 견인 후 finishing 기간동안 tooth positioner를 사용하였다. 상악 구치부의 장치부착 없이도 총 치료기간은 19개월 소요되었고, 안정적인 교합관계와 안모의 개선이 이루어졌다. 장치 제거 후 13개월 유지 후에도 양호한 결과가 유지되었다.
