초록

Purpose：Schulte introduced immediate implant cases in 1970s, since then many patients have been treated by immediate
implants. The aim of this study was to evaluate the cumulative survival rate of immediate implant and to analyze various factors
associated with survival of immediate implant in a 8-year period retrospectively.
Materials and methods：From May, 2000 to October, 2007, 77 implants were placed in 63 patients immediately after tooth
extraction at Department of Periodontology, Yonsei University Hospital. The implant survival rate was analyzed using a life-table
analysis. After delivery of prosthesis, along 1 year of observation period, all implants were evaluated clinically and
radiographically.
Results：Among 77 implants, 59 were placed in maxilla and 18 in mandible. The most common site of the implantation was
Mx anterior (65%). The overall survival rate was 94.8% over a mean follow-up period of 44.2±21 months and the 8-year
cumulative survival rate was 94.6%. Failure occurred in 4 implants, all of which were due to early failures. None of the following
factors were significantly associated with the survival of immediate implants: advanced surgical technique including bone graft
and guided bone regeneration, the types of implants, causes of tooth loss, and types of prosthesis.
Conclusion：On the basis of 8-year life time analysis, immediate implant placement can be considered a safe and predictable
treatment mordality.
