초록
편악 부분 무치악 환자를 치료하는 경우, 적절한 수복 재료를 사용하는 것이 중요하다. 적절하지 않은 수복 재료는 보철 수복의 결과에 좋지 않은 영향을 줄 수 있다. 현재 널리 사용되고 있는 재료들인 지르코니아와 치과용 합금은 피질골보다 탄성 계수가 높아 외력 발생시 임플란트 및 임플란트 주위 골에 유해한 힘을 가할 수 있다. 최근 새롭게 소개된 재료인 Polyetherketoneketone (PEKK)은 피질골과 유사한 탄성계수를 가졌으며, 물리적 특성 및 생체 친화성에 있어서도 많은 이점을 가지고 있다. 본 증례에서는 PEKK를 이용한 임플란트 지지형 고정성 보철치료를 진행하였고 기능적, 심미적으로 만족할 만한 결과를 얻었기에 이를 보고하는 바이다.
Abstract
When treating partial edentulous patients, it is important to use an appropriate restorative materials. Inappropriate restorative materials can adversely affect the outcome of prosthetic restorations. Zirconia and dental metal, which are currently and widely used materials, have a higher elastic modulus than cortical bone, so when an external force is generated, a harmful force can be applied to the implant and the bone around the implant. Polyetherketoneketone (PEKK), a recently introduced material, has a elastic modulus similar to that of cortical bone, and has many advantages in terms of physical properties and biocompatibility. This case report describes that implant-supported fixed prosthetic treatment using PEKK was performed, and functional and esthetic satisfactory results were obtained.
