초록
상악 전치부에 임플란트를 이용해 심미적으로 수복 하는 것은 많은 어려움이 따른다. 이는 치조골 흡수와 치간 유두 수축 등과 같은 임플란트 주변 경, 연조직 문제와 금속지대주 및 금속도재관의 변연노출과 낮은 광투과도 등의 보철적 한계 때문이다. 이에 본 증례에서는 경, 연조직의 증대술 및 성형술, 발치 후 즉시 식립 등과 함께 임시수복물의 장기간 사용 및 수정으로 임플란트 주위 연조직의 형태와 건강을 형성한 후, 맞춤형 인상 코핑을 사용하여 이를 최종 모형에 재현하였다. 또한 맞춤형 지르코니아 지대주와 완전 도재관을 이용해 최종 수복함으로써 기능적이고 심미적인 결과를 얻었기에 이를 보고하고자 한다.
Abstract
It is so hard to obtain optimal anterior esthetics in the implant prosthesis. This is not only because of hard and soft tissue problem such as alveolar bone resorption and interdental papilla loss but also because of prosthetic limitation related to marginal exposure of metal abutment and metal ceramics and low transillumination. In this case, guided soft tissue healing is obtained using a long term provisional restoration with soft and hard tissue augmentation or immediate implantation. Then, this healed tissue is transferred to final master model using a customized impression coping and the implant is restored with a customized zirconia abutment and a all ceramics. This case presents satisfying result esthetically and functionally.
