Abstract

Purpose: The aim of the present prospective clinical study was to assess the cumulative survival rate (CSR) of Neobiotech implants restored with fixed partial prosthesis in relation to its potential risk factors. Materials and methods: Thirty six partially edentulous patients received Neobiotech implants and implant supported fixed partial prosthesis at Korea University Guro Hospital Dental Center from November 2009 until November 2011. The observation period was set from the implant placement and the last clinical visit until December 2015. Implant survival rate was determined using the Kaplan-Meier method. The relationship between implant survival rate and the potential risk factors were analysed using the multi Cox proportional analysis (P<.05). Results: A total of 69 implants were placed in 36 patients after a mean observation period of 45.9 months. Two out of 69 implants failed before loading, yielding a 5-year cumulative survival rate of 97.1%. The maxillary implants have a lesser CSR than the mandibular implants based on log rank test analysis (maxilla=91.3%; mandible=100% P<.05). However, the multi Cox proportional analysis showed that implant location has no significant correlation with implant failure (P>.05). Conclusion: Neobiotech implants showed predictable results with a 5 year cumulative survival rate of 97.1%.

목적: 본 전향적 임상 연구의 목적은 고정성 보철물로 수복 된 Neobiotech 임플란트의 누적생존율 및 임플란트 실패의 위험 인자를 평가하는 것이다. 재료 및 방법: 본 연구는 고려대학교 구로병원 치과 센터에서 2009년 11월부터 2011년 11월까지 Neobiotech 임플란트와 임플란트 지지 고정성 보철치료를 받은 부분 무치악 환자 36명을 대상으로 시행하였다. 관찰 기간은 임플란트 식립일에서 2015년 12월 이전 마지막 방문일까지로 설정하였다. 임플란트 생존율은 Kaplan-Meier 방법을 이용하였으며, 임플란트 실패에 대한 위험 인자 평가는 다중 콕스 비례 분석을 이용하여 분석하였다 (P < .05). 결과: 36명의 환자에게 총 69개의 임플란트가 식립되었으며, 평균 관찰 기간은 45.9개월이었다. 총 69개의 식립된 임플란트 중에 2개의 임플란트가 하중을 가하기 전에 실패하여 97.1%의 5년간 누적 생존률을 보였다. 로그 랭크 테스트 분석 결과 상악에 식립된 임플란트는 하악에 식립된 임플란트보다 낮은 임플란트 생존율을 나타내었다 (상악=91.3%, 하악=100%, P < .05). 하지만 다중 콕스 비례 분석 결과 임플란트 위치와 임플란트 실패는 유의한 상관 관계가 나타나지 않았다 (P > .05). 결론: Neobiotech 임플란트의 5년간의 누적 생존율은 97.1%를 나타내었다.
