역행성 임플란트 근단병소 주위염은 임상증상을 동반한 근단부의 방사선 투과성 병소로 정의되며 임플란트 식립부위 또는 인접한 치아의 잔존하고 있는 감염에서 유래한 세균감염, 골 삭제시의 열 발생 등의 다양한 원인에 의해 야기될 수 있고, 다양한 치료방법으로 임플란트를 제거하지 않고 유지할 수 있는 증례들이 보고되고 있다. 본 증례에서는 근관 치료 실패로 발치한 상악 우측 제2소구치 부위에 식립한 임플란트에서 발생한 역행성 임플란트 근단병소 주위염을 표면의 detoxification과 차폐막과 골이식재를 동반한 골유도재생술로 해결하여 기능을 회복하였으며, 7년간 장기적으로 안정적으로 유지되고 있는 증례에 대해 보고하고자 한다.
Abstract
Retrograde peri-implantitis (RPI) is defined as a clinically symptomatic periapical lesion. RPI is generally accompanied by symptoms of pain, tenderness, swelling and fistula. Several etiologic factors of RPI were possible, residual bacteria would be the main cause of RPI. Various treatment modalities have been introduced: debridement only or a combination of debridement with the grafting material accompanied by a detoxification of the infected implant surfaces, apicoectomy and so on. Although the definitive management methods remain undefined, many favorable clinical results of a treatment of RPI have been published. This case report introduces the 7-year long-term clinical result of the application the principle: implant surface detoxification using saline and chlorhexidine and guided bone regeneration with bone graft material and barrier membrane. If the implant was not mobile, it would be possible to treat RPI according to surgical approach and good results will be maintained over long term.
