Abstract

결과
저자는 연세대학교 치과병원 소아치과에 내원한 유치매복의 환아들의 검사와 치료 과정에
서 다음과 같은 결과를 얻었다.
1. 본 증례의 유치매복원인은 비 정상적인 맹출경로, 치아종과 섬유성 치은조직이다.
2. 본 증례에서 유치의 매복으로 계승 영구치의 맹출장애와 공간의 소실이 나타났다.
3. 매복치의 상태 및 계승 영구치와의 관계에 따라 적절한 치료계획을 세워야하며, 계승영
구치의 발육과 맹출에 대한 지속적인 관찰과 처치가 필요하다.

The term impaction is defined as a tooth has failed to erupt into normal position
beyond the time usually expected for such appearance. Most of the cases of unerupted
and impacted teeth reported in the literature are of permanent teeth. Pindborg stated
that failure of a primary tooth to erupt occurs rarely. Impactions of mandibular primary
second molars, however, are as numerous as all other primary impactions combined.
Eearly detection of impaction is necessary during periodic oral examination and also
radiographic examination and proper management is needed, because impaction of
primary tooth may lead to obstruction of successive permanent tooth, space loss, and
cystic change of tooth follicle. In these cases, 5 cases of primary teeth impaction are
presented. Impaction teeth of each cases are maxillary primary incisor, maxillary and
mandibular second primary molar, mandibular first primary molar.
Following results were achieved by these cases:
1. In this cases, the cause of primary tooth impaction are abnormal eruption path,
odontoma and fibrotic gingiva.
2. In this cases, impactions of primary tooth results in eruption problem of successive
permanent tooth and failure of space maintenance.
3. Proper treatment plan should be established after through consideration of impacted
tooth and it’s relation with successive permanent tooth, and periodic examination and
proper treatment about successive permanent tooth and eruptive condition is needed.
