Abstract

An implant-supported hybrid prosthesis is a fixed restoration composed of a metal framework and acrylic resin, offering advantages such as aesthetics, function, phonetics, and lip support, while providing retention and support through the splinting of implants with the metal framework. However, poor oral hygiene can lead to peri-implantitis, and long-term use may result in wear or fracture of the artificial teeth, causing reduced masticatory function and loss of vertical dimension. Traditionally, a new metal framework is cast for remanufacturing, but if the existing framework is intact, it can be reused for a more rapid and simplified protocol. This case involves a 58-year-old male patient with peri-implantitis, where some implants were removed and treated, and the superstructure was remanufactured using the existing metal framework. By preserving the existing metal framework during the remanufacturing of the implant-supported hybrid prosthesis, the treatment time and number of visits were reduced, minimizing patient discomfort.

임플란트 지지 하이브리드 보철물은 금속 구조물과 아크릴릭 레진으로 구성된 고정성의 보철물로, 심미, 기능, 발음, 구순지지 등의 이점을 가지며, 임플란트를 금속 구조물로 연결 고정하여 유지와 지지도 함께 제공할 수 있다. 그러나 올바른 구강위생관리가 동반되지 않으면 임플란트 주위염이 발생할 수 있고, 장기간 사용 시 인공치의 마모나 파절로 저작기능 감소와 수직교합고경의 상실이 발생할 수 있다. 전통적으로는 새로운 금속 구조물을 주조하여 재제작해야 하지만, 기존 금속 구조물이 건전하다면 이를 재사용하여 보다 빠르고 간단하게 제작할 수 있다. 본 증례는 58세 남환으로 임플란트 주위염이 확인되어 일부 임플란트를 제거하고 치료한 후, 기존 금속 구조물을 이용해 상부 보철물을 재제작하였다. 기존 금속 구조물을 유지하여 임플란트 지지 하이브리드 보철물을 재제작함으로써 치료 기간과 내원 횟수를 줄여 환자의 불편을 최소화하였기에 이를 보고하는 바이다.
