Abstract

Early interceptive orthodontic interventions are often started in the developing dentition to guide normal occlusion. The simplest way to prevent eruption failure from deciduous tooth loss is to fix a space maintainer such as a band and loop. Band and loop space maintainer has several problems like cement loss, demineralization, locking of the adjacent tooth, and needs to take a pickup impression of the band. Computer-assisted design/computer-assisted manufacturing (CAD/CAM) space maintainer without band was developed to solve these problems. This case report describes successful eruption of the mandibular second premolar using CAD/CAM without a band.

조기 교정치료의 개입은 종종 성장하는 치열을 정상 교합으로 유도하는 것에서부터 시작된다. 유치의 상실로 인한 맹출 실패를 예방하는 가장 간단한 방법은 밴드 및 루프와 같은 공간 유지장치를 부착하는 것이다. 밴드 및 루프 공간 유지장치는 밴드의 픽업 인상 과정을 거쳐야 하며, 시멘트 소실과 탈회, 인접치의 locking과 같은 문제들을 갖고 있다. 이러한 문제를 해결하기 위해서 CAD/CAM을 이용한 band가 필요 없는 공간유지장치가 개발되었다. 본 증례는 밴드 없이 CAD/CAM을 이용하여 하악 제2소구치가 성공적으로 맹출할 수 있었기에 이를 보고하는 바이다.
