A 10-year retrospective clinical study of Branemark implants / 대한치과보철학회지

ABSTRACT

STATEMENT OF PROBLEMS There are few studies which reported the survival rates of the specific dental implant systems in the Korean population with the follow-up periods longer than 5 years. PURPOSE: This retrospective clinical study was aimed to evaluate cumulative survival rate (CSR) of Branemark implants followed for 10 years and to determine risk factors for implant failure. MATERIAL AND METHODS: A total of 271 Bra.nemark implants in 83 patients were investigated with several identified risk factors. Life table analysis was undertaken to examine the CSR. Cox regression method was conducted to assess the association between potential risk factors and overall CSR. RESULTS: Thirty implants failed. The 10-year implant CSR was 82.5%. Cox regression analysis demonstrated a significant predictive association between overall CSR and implant length (P<.05). CONCLUSION: An acceptable long-term result of Branemark implant was achieved and implant length showed a significant association with the CSR.
