Abstract

Although the proportion of edentulous patients is declining, the aging population has resulted in an increase in their absolute numbers. Conventional complete dentures can partially restore oral function but have significant limitations such as low retention and relatively poor masticatory ability. Therefore, implant overdentures have been proposed as an alternative, offering enhanced functionality, higher patient satisfaction, and cost-effectiveness compared to fixed implants. In this case, a 74-year-old female patient presented with complaints about her existing implant overdenture, fabricated in 2010, which frequently dislodged and was aesthetically unpleasing. Clinical examination revealed worn attachments and artificial teeth, as well as insufficient upper lip support. It was decided to remake the implant overdentures utilizing the existing implants. During the fabrication, the patient continued to use her previous denture. After evaluating the occlusal relationships, facial form, and vertical dimension, the new overdentures were fabricated. The newly created implant overdentures showed satisfactory aesthetic and functional results, and the patient was satisfied.

무치악 환자의 비율은 감소하고 있지만, 인구 고령화로 인해 절대적인 환자 수는 증가하고 있다. 전통적인 총의치는 구강 기능을 일부 회복할 수 있지만 유지력이 낮고 저작능력이 상대적으로 떨어진다는 한계가 있다. 따라서 고정성 임플란트에 비해 상대적으로 경제적이며, 높은 환자 만족도, 적절한 기능을 제공하는 임플란트 오버덴처가 대안으로 제안되었다. 본 증례의 74세 여환은 2010년에 제작한 기존 임플란트 피개의치의 모양에 대한 불만과 유지력 저하를 주소로 본원에 내원하였다. 임상 검사 결과 인공치 및 어태치먼트의 마모가 확인되었고, 불충분한 입술 지지가 나타났다. 따라서 기존 임플란트를 활용하여 임플란트 오버덴처를 재제작하기로 결정하였다. 제작하는 동안 환자는 기존 의치를 계속 사용했다. 교합 관계, 안면 형태, 수직 고경을 평가한 후 새로운 피개의치를 제작하였다. 새롭게 제작된 임플란트 피개의치는 만족스러운 심미적, 기능적 결과를 보였고 환자도 만족하였다.
