Abstract

Fixed implant prosthesis and removable implant overdenture are the main treatment options for treating edentulous maxilla with implants. If clinicians select one of the treatment options without accurate diagnosis and evaluation, this may lead to unfavorable treatment result and one would not be able to guarantee successful long term prognosis. In this case, 69 year-old female presented with failed fixed implant prosthesis that was treated in private dental clinic. Since the patient did not want additional insertion of implants and considering factors such as oral hygiene maintenance, splinting effect, and esthetics, the patient was treated with removable implant bar type overdenture using pre-existing implants. The clinical results were satisfactory in the aspect of esthetics and masticatory function, oral hygiene maintenance.

고정성 임플란트 보철물과 가철성 임플란트 피개의치는 상악 완전 무치악 환자를 임플란트를 이용하여 치료하는 대표적인 두 가지 방법이다. 임플란트 보철물 선택 시 정확한 진단과 평가가 이루어 지지 않고 치료방향을 선택하게 되면 생역학적, 기능적 및 심미적으로 불리한 치료결과를 낳고 장기적인 예후 또한 보장할 수 없다. 본 증례의 환자는 개인치과의원에서 상악 완전 무치악에 8개의 임플란트를 식립하여 고정성 보철물로 치료하였으나 상악 보철물의 실패로 인해 재치료를 위해 내원하였다. 환자의 요청으로 추가적인 임플란트를 식립 할 수 없었고 구강위생관리 문제 해결, 기존 임플란트의 활용 및 연결 고정을 통한 안정화, 심미성 등을 고려하여 바를 이용한 가철성 피개의치로 치료를 결정하였다. 심미성과 저작기능, 구강위생관리에 만족할 만한 결과를 얻었기에 이를 보고하고자 한다.
