Abstract

The optimal time for the removal of supernumerary teeth can be divided into two groups; early removal and late removal. While each group has its own advantages, the effects on maxillary central incisor can be significant. The purpose of this study was to determine the ideal time for the removal of the supernumerary teeth by evaluating 166 patients for three months after surgical removal of supernumerary teeth. Relatively young patients in early Hellman's dental stage with less developed or unerupted maxillary central incisor had less midline deviation. No statistical significance was found in diastema, rotation of the maxillary incisors and their changes during a follow-up period. Removal of supernumerary teeth should be considered as a preventative measure prior to eruption of the maxillary incisors when the midline deviation is observed in panoramic radiographic examination. This study will be useful in determining the optimal time for the removal of supernumerary teeth depending on the location of the maxillary incisors. This study will be informative on deciding the optimal time to remove the supernumerary teeth depending on the various positions of the maxillary central incisor. (this sentence is better to use)

과잉치의 발거시기는 조기발거와 지연발거로 나뉠 수 있으며 각각의 장단점이 있으며 특히 상악 중절치에 미치는 영향이 크다. 이 연구에서는 과잉치 발거 후 3개월 이상 추적관찰이 시행된 166명을 조사하여 최적의 과잉치 발거시기를 결정하고자 하였다. 환자의 나이가 어리고, 상악 중절치 미맹출 혹은 발육단계가 낮고, Hellman's dental stage상 낮은 단계에서 정중선 변위는 적게 일어났다. 정중이개와 상악 중절치의 회전, 추적 관찰 기간에 따른 변화는 통계적 유의성이 없었다. 상악 중절치가 아직 맹출하지 않은 경우라 하더라도 파노라마 방사선 사진을 촬영하여 정중선 변위가 보인다면 이른 시기에 과잉치를 발거할 필요가 있다. 이 연구는 상악 중절치의 위치 변위에 따라 과잉치의 발거시기를 결정하는 데에 도움을 줄 수 있을 것이다.
