초록

자가치아이식은 생물학적 적합성과 치조골 보존 효과로 인해 치과 임플란트의 대안으로 고려될 수 있다. 이번 증례 보고에서는 두 명의 환자에서 시행된 치근 완성된 제3대구치의 자가치아이식의 과정과 술식을 제시하고 자가치아이식의 장점, 한계점 및 성공적인 이식을 위한 주요 고려 사항에 대해 논의하고자 한다. 첫 번째 증례에서 39세 여성이 상악 우측 제2대구치가 파절로 인해 발치 되어 임플란트 치료가 의뢰되었으며, 처음에는 임플란트가 고려되었으나, 환자의 나이를 고려하고 반대편 상악 제3대구치가 근심경사되어 있고 치아우식증이 있어 발치되어야 하였으므로 자가치아이식이 선택되었다. 두 번째 증례에서 40세 여성은 좌측 하악 제2대구치의 근단병소로 인해 발치되어 있었고 임플란트 식립을 위해 의뢰되었다. 동측 하악 제3대구치를 이용하여 자가치아이식을 시행하였다. 적절한 공여치아의 선택, 술전 콘빔컴퓨터단층 촬영 및 모형 제작, 조심스러운 발치, 적절한 수여부의 골 삭제 및 봉합사를 이용한 치아 고정, 근관 치료의 과정을 단계별로 신중히 시행하여 두 증례 모두에서 성공적인 치유 과정과 기능적 적응을 보였다.

Autotransplantation of teeth is a valuable alternative to dental implants, offering biological compatibility and preservation of alveolar bone. This case report presents two patients who underwent autotransplantation and also discusses the advantages, limitations, and key considerations for successful autotransplantation. A 39-year-old female, received autotransplantation of a left maxillary third molar to replace a non-restorable right maxillary second molar due to fracture. Initially, an implant therapy was considered, but due to the patient's age and contralateral maxillary third molar's extraction need, autotransplantation was selected. A 40-year-old female, underwent autotransplantation of a left mandibular third molar to replace a left mandibular second molar lost due to failed endodontic treatment. The process of selecting an appropriate donor tooth, preoperative CBCT imaging, 3D model making, careful extraction, appropriate osteotomy of recipient socket, tooth fixation, and root canal treatment were carefully performed step by step, resulting in successful healing and functional adaptation in both cases.
