치주적으로 지지가 불리한 소수의 잔존치가 남은 환자에게 있어 하이브리드 텔레스코픽형 이중관의치는 장기적으로 안정적인 예후를 보이는 치료가 된다. 편측 악궁에 소수 잔존치가 남고 반대측 악궁에 다수의 자연치가 존재 하는 경우 임플란트를 식립하여 자연치와 혼재된 형태의 이중관 의치를 제작 할 시 의치의 지지 및 안정요소의 향상과 더불어 저작력의 균형을 맞추어 줄 수 있게 된다. 본 증례는 55세 여자 환자로 만성 치주염으로 인해 치주지지가 감소한 소수 잔존치 상태에서 자연치만으로 하이브리드 텔레스코픽형 이중관 의치 치료를 통해 9.5년간 의치를 사용하였다. 9.5년 후 지대치 파절로 내원 하여 임플란트의 식립을 통해 자연치와 임플란트가 혼재된 하이브리드 텔레스코픽형 이중관 의치로 재수 복 하였으며, 이를 통해 재 치료에서도 장기적 예후의 안정성을 기대 할 수 있다.
Abstract
Hybrid telescopic double crown have ever been good treatment option for patient with periodontally unfavorable few remaining teeth for successful prognosis. Tooth and implant combined telescopic double crown can be used for improving retention and support for denture with strategically placed implants on edentulous ridge. In this case, an 55-year-old female patient had chronic periodontitis with few remaining teeth on maxilla and fixed partial prosthodontics on mandible. Treatment of hybrid telescopic double crown with friction pin lasted 9.5 years only with natural teeth. After 9.5 years, additional implants was installed due to fracture of cast-posted abutment teeth. After implantation, tooth and implant combined double crown had fabricated. Through re-treatment, no complications of new denture has been found during 2 years follow up. This case presents fair prognosis of tooth and implant combined double crown denture in periodontally unfavorable condition.
