초록

이 연구의 목적은 임플란트 보철물과 자연치 사이의 인접접촉강도의 경시적 변화를 평가하는 것이다. 단일 임플란트 보철물을 장착한 31명(상악제2대구치; 13명, 하악 제2대구치; 18명)의 피험자에게서 측정이 이루어졌다. 측정은 교합되지 않은 안정 상태에서 임플란트 보철 장착 직후, 1개월 그리고 6개월 후에 이루어졌다. 임플란트 보철물과 자연치 사이의 접촉강도는 상악(p<.01), 하악(p<.05) 모두 시간이 흐름에 따라 감소하였다.

The aim of this study was to evaluate time serial change of the TPTC(Tightness of Proximal Tooth Contact) between the implant prosthesis and natural tooth at rest state. Thirty-one patients(19 males and 12 females; mean age, 48.2 years) restored with a total 31 single-implant crowns in the left maxillary for 13 single-implant and left mandibular second molars for 18 single-implant crowns, respectively were selected. The TPTC was checked directly after delivery, 1 month after delivery and 6 months after delivery of prothesis at rest state. The TPTC decreased significantly as time goes by both maxilla(p<.01) and mandible(p<.05). The TPTC between the implant prosthesis and natural tooth decreased as time goes by after fixed implant prothesis placement.
