초록

이 연구는 영구 제1대구치 기성금속관에 있어서 장기간 생존율을 후향적으로 평가하고 생존율에 영향을 미치는 요소를 분석하고자 하였다. 10년 동안 수복된 115개의 제1대구치 기성금속관을 후향적으로 분석하였으며, 제1대구치 기성금속관의 5년 생존율 82.8%로 나타났으며 원심와동, 하악 치아에서 생존율이 유의하게 낮게 나타났다. 이 연구를 통해서 임상적으로 기성금속관 성공률에 영향을 미치는 요인들을 확인하였으며, 성공률을 높이기 위한 치료지침을 확립하는데 도움이 될 수 있으리라 생각된다.

This study analyzed the longevity of preformed metal crowns (PMCs) in first permanent molars and evaluated factors influencing their survival during a long-term follow-up period. In all, 115 first permanent molars treated with PMCs between June 2008 and June 2018 were retrospectively analyzed. The overall combined success rate for the study group was 84.3%. The 5-year survival rate was 82.8%. Multivariate Cox regression analyses identified distal cavities and mandibular PMC placement as risk factors for restoration failure. Careful placement of PMCs at the final try-in stage augments the longevity of the crown.
