Abstract

The treatment of Class II non-extraction cases, especially when premolar space is lost due to premature loss of the deciduous molars, usually requires distal movement of the maxillary molars. The Jones jig appliance is a non-compliant intraoral appliance and is effective for the distalization of the maxillary molars. It has unfavorable side-effects, however, so caution is needed to adjust the appliance and select appropriate cases. We reported four cases in which maxillary molar distalizations were concomitant with the alignment of palatally erupted premolars.

II급 부정교합 비발치 치료 시, 특히 유구치의 조기탈락으로 인해 소구치 공간이 상실된 경우 상악 대구치의 원심이동이 필요하게 된다. Jones jig 장치는 환자의 협조가 필요치 않은 구내장치 중 하나로 효과적인 구치 원심이동을 이룰 수 있다. 그러나 고정원의 상실로 인한 부작용이 나타날 수 있으므로 장치 조정과 환자의 선택에 신중을 기해야 한다. 본 증례에서는 Jones jig 장치로 효과적인 구치 원심이동과 더불어 elastic thread를 사용하여 구개측으로 맹출한 소구치의 치열궁 내 배열을 가능하게 하는 부가적인 장점을 경험하였기에 보고하는 바이다.
