초록

상악 전치부의 임플란트 식립 시 치은 퇴축이나 골 결손 문제를 동반하는 경우에는 심미적인 임상 결과를 얻기가 쉽지 않다. 본 증례에서는 상악 우측 중절치에서 순측 치조골판의 소실이 진단되어 발치 후 연조직을 확보한 후에 골 이식을 동반하는 임플란트 식립을 계획하였다. 또한 이상적인 임플란트 식립 위치를 위해 디지털 가이드 수술을 시행하였고, 치조골 결손부가 광범위하기 때문에 하악지에서 자가골 채취 후 이종골과 함께 골유도재생술을 동반하였다. 충분한 임플란트의 골 유착 기간을 거친 뒤 2차 수술 및 인상 채득을 통한 임시 보철물을 제작하였고, 주기적인 외형 조정을 통해 연조직의 형태를 개선하였다. 최종 보철물 제작시에는 양극 처리를 시행한 맞춤형 지대주를 사용하여 자연 치아의 색조를 유도하였고, 구강 스캔을 통하여 임시 보철물의 형태를 재현해 줌으로써 심미적이고 기능적인 지르코니아 보철물을 장착해 주었다.

In case of gingival recession or bone defect in maxillary anterior implant treatment, it is not easy to obtain satisfactory clinical results. In this case, loss of the labial alveolar plate was diagnosed in the maxillary right central incisor, so after tooth extraction, soft tissue was secured and implant placement with bone graft was planned. In addition, digital guide surgery was performed for the ideal implant position, and GBR (Guided Bone Regeneration) was accompanied with the xenogeneic bone and the autologous bone collected from the mandibular ramus since alveolar bone defects were extensive. After a sufficient period of osseointegration of the implant, a temporary prosthesis was fabricated through secondary stage surgery and impression taking, and through periodic external adjustment, the shape of soft tissue was improved. In the final prosthesis fabrication, a color tone of natural teeth was induced by an gold anodized customized abutment, and an aesthetic and functional zirconia prosthesis with reproducing the shape of the temporary prosthesis through intraoral scan was delivered.
