초록

상악 전치부는 심미적으로 중요한 역할을 하는 치아이다. 그러므로 발치 후 심미적인 보철 수복을 위하여 경조직 및 연조직의 보존이 중요하다. 상악 전치부 상실을 임플란트를 이용하여 수복하는 경우 몇 가지 난관에 부딪히게 된다. 즉 수복물과 인접치와의 색상 및 형태, 인공치 표면의 조화 및 치은연과의 조화로운 연속성 등이다. 본 증례는 외상으로 인하여 상악 중절치와 측절치의 치관-치근 파절을 주소로 내원하였다. 예후가 불량한 파절 치아를 모두 발치 하였으며 상악 전치부 결손부위에 골이식을 동반한 임플란트를 식립하였다. 보다 나은 심미적 결과를 위하여 캔틸레버 임플란트 보철물을 계획하였고 인공치아 연하의 치조점막을 지속적으로 조정하였고 그것을 정확하게 인기해내는 맞춤형 인상코핑을 이용하여 임플란트 심미 보철 수복을 시행하였다. 최종치료 후 심미적, 기능적으로 만족스러운 결과를 얻었기에 이를 보고하고자 한다.

The maxillary anteriors play an important role in esthetics. Therefore after extraction, it is crucial to preserve the hard tissue and soft tissue in order to promote esthetics of restoration. There are several challenges when restoring the maxillary anteriors via implant. Some of the challenges are be maintaining consistency with neighboring teeth in terms of shade, form, and texture : as well as having harmonious emergency with the gingival margin. In this case, a traumatized patient with crown-root fracture of the maxillary central and lateral incisors is presented. The cracked teeth were extracted, and implants were inserted with bone grafts to compensate the volume of damaged area of the maxillary anterior. Cantilever implant prosthetics were planned while precise adjustments to the gingival area were made using customized impression coping to perform the esthetic restorations. The final outcome of the treatment was satisfying in both esthetic and utilitarian perspective.
