초록

본 증례의 환자는 기존 의치에 불편함을 느껴 새로운 의치를 원하여 내원하였다. 하악 좌측 제2대구치를 제외한 모든 치아를 상실한 상태였다. 환자의 나이가 65세였기에 임플란트와 의치를 국민건강보험 제도를 이용하여 치료할 수 있었고, 환자는 하악에 임플란트를 이용한 의치 제작을 원하였다. 새 의치에 적응하기 위해 임시 의치를 제작하여 장착하고 충분한 적응 기간을 거쳐서 치료를 진행하였다. 상악은 총의치, 하악은 전방부에 임플란트 2개를 식립하여 임플란트 상부 보철물을 서베이드 크라운 형태로 제작하고 임플란트 보조국소의치를 제작하였다. 골흡수가 심한 하악 소수 잔존치 상태에서 효율적인 치료 비용과 기능적으로 환자와 술자 모두 만족하였다. 임플란트 상부 보철물을 서베이드 크라운 형태로 제작한 임플란트 보조 국소의치는 경제적, 해부학적인 한계로 총의치, 임플란트 피개의치, 임플란트 지지 완전 고정성 보철이 어려운 경우에 효과적인 대안이 될 수 있다. 그러나 과학적으로 근거가 높은 수준의 연구가 부족하여 향후 면밀한 정기검진 및 교합 검사가 필요할 것이다.

The patient in this case presented with a desire to have new dentures due to discomfort with existing ones. At the initial visit, all of teeth were missing except for the mandibular left second molar. As the patient was 65 years old, treatment with dentures and implant-supported prostheses was possible under the national health insurance system, and the patient opted for the mandibular denture using implant. Temporary prostheses were initially provided for patient adaptation, and following successful adaptation period, the treatment progressed. A maxillary complete denture and a mandibular implant-supported denture using two implants in the canines were fabricated. The mandibular denture is a Kennedy Class II removable partial denture which consists of a six-unit porcelain fused to metal fixed dental prostheses supported by the implant in the canines on both sides and left second molar serving as the abutments. Despite severe bone resorption and insufficient abutment teeth, the patient expressed satisfaction with the treatment results. In cases with economic and anatomical constraints affecting the feasibility of complete denture, implant-supported overdenture, and implant-supported fixed dental prostheses, an implant-assisted removable partial denture using implant surveyed crowns proves to be a viable and effective alternative treatment option. Nevertheless, the current dearth of scientifically rigorous studies underscores the necessity for meticulous regular check-up and occlusal assessment.
