Abstract

Esthetics is important in restoring maxillary anterior area. Alveolar bone resorption and loss of interdental papilla may be minimized by immediate implantation. Previous studies showed successful results with the immediate implantation in healthy extraction socket, while many of these studies objected the immediate implantation into extraction sites with periapical lesions. Recent studies, however, reported successful results of the immediate implantation into extraction sites with periapical lesions with careful debridement of extraction sockets and general medication of antibiotics prior to implantation. A 73-year-old female visited the department of Prosthodontics in ${\bigcirc}{\bigcirc}$ University Dental Hospital with the chief complaint of fallen post-core and crown on left maxillary incisor. Although the incisor was with vertical root fracture and periapical lesion, the immediate implantation following the extraction of tooth was planned. Thorough socket debridement, irrigation with chlorhexidine, and tetracycline soaking were followed by immediate implantation. The general medication of antibiotics (Moxicle Tab.$^{(R)}$, 375 mg) was prescribed before and after the surgery. Immediate provisional restoration was delivered two days after the surgery, and the definitive metal-ceramic restoration was placed about six months later after reproducing the emergence profile from the provisional restoration. This case presents satisfying result esthetically and functionally upto two years after the placement of prosthesis with the harmonious gingival line and no loss of marginal bone.

상악 전치부는 심미적 회복이 강조되는 부위다. 발치 후 치유될 때까지 기다린다면 치조골 흡수와 치간 유두 수축을 방지할 수 없다. 일단 흡수된 조직을 재생하기 위해서는 추가적인 외과적 술식이 필요하고 치료 기간도 많이 소요된다. 발치 전 치조골과 치은 조직이 건강하다면 치주 조직을 보존 유지하기 위해 발치와 동시에 즉시 임플란트 식립을 고려할 수 있다. 특히 건전한 발치와에서의 즉시 임플란트 식립은 여러 논문에서 성공적인 결과를 보였다. 치근단 병소가 존재하는 치아의 발치 후 즉시 임플란트 식립에 대해서는 부정적인 반응을 보이는 연구가 많았으나, 최근에는 확실한 발치와의 육아조직제거와 전신적 항생제 투여 시 성공률이 높다는 결과도 보고되고 있다. 본 증례는 73세 여환으로 상악 좌측 중절치의 포스트-코어와 금속도재관이 탈락되었으며 임플란트 치료를 받고 싶다는 주소로 내원하였다. 치근단 병소와 수직적 치근 파절이 존재하였으나 치근단 병소가 있는 치아에서도 즉시 임플란트 식립의 성공사례가 여러 차례 보고되어 발치 및 즉시 임플란트 식립을 계획하였다. 발치 후 발치와 육아조직제거와 클로르헥시딘 용액 소독 및 tetracycline 용액으로 soaking을 시행한 후 임플란트를 식립하였으며 식립 전 후로 전신적 항생제를 투여하였다. 임플란트를 식립하면서 인상채득하여 2일 뒤 임시 보철물을 장착하였다. 약 6개월 뒤 치경부 형태를 재연하여 최종 인상 채득하였으며 최종 보철물을 장착하였다. 보철물 장착 후 2년까지 치은선이 인접치아와 조화를 이루고 변연골 흡수없이 심미적으로 만족할만한 결과를 얻었기에 보고하는 바이다.
