초록
임플란트를 이용한 완전 무치악 환자의 치료에 있어 가장 중요한 것은 최종 보철물의 형태이며, 최종 보철물의 형태가 결정된 후 잔존골 분석 및 식립할 임플란트의 종류, 개수, 위치 등에 대한 선택이 이루어져야 한다. 본 증례는 상악 우측 측절치를 제외하고 전악에 임플란트가 식립된 채로 내원한 환자에 대해 고정성 보철 수복한 증례이다. 최종 보철물에 대한 고려 없이 임플란트가 식립되었기 때문에 먼저 총의치를 제작하여 안모 분석 및 고정성 보철 수복 가능성을 평가하였다. 고정성 보철 수복이 가능하다고 판단되어 진단 납형, 방사선 영상 및 디지털 분석을 통해 최종 보철물에 사용할 수 없는 임플란트를 치료계획에서 제외한 후 고정성 임시 보철물을 제작하였다. 4개월 동안 고정성 임시 보철물을 사용하면서 안정적인 교합과 심미적인 만족을 보였기에 CAD/CAM (Computer aided design and computer aided manufacturing)을 이용하여 지르코니아 최종 보철물로 이행하였고, 치료 종료 후 3개월 동안의 평가에서 만족스러운 결과를 얻었다.
Abstract
The most important factor in the treatment of fully edentulous patients using implants is the shape of the definitive prosthesis. After the shape of the definitive prosthesis is determined, residual bone analysis and selection of the implant type, number and position should be followed. In this case, for restoration of an edentulous patient fully implanted (except the maxillary right lateral incisor) without considering definitive prosthesis, facial esthetics and possibility of fixed type prosthesis were evaluated using complete denture. It was determined that the fixed type prosthesis was possible. Implants that could not be used for the definitive prosthesis were excluded from the treatment plan and fixed type provisional restorations were fabricated. After four months of provisional restorations, the patient showed stable occlusion and esthetic satisfaction. Definitive prosthesis was made of zirconia using CAD/CAM (computer aided design and computer aided manufacturing). The results were satisfactory during the 3 months of follow-up period after termination of treatment.
