다국어 초록 (Multilingual Abstract)
Purpose
The purpose of this study was to assess the survival rate of implants in edentulous area of elderly patients and to evaluate the influence of local factors on implant survival in elderly patients.
Material and methods
Among dental implants placed in the department of periodontology, Chosun University Dental Hospital from January 2001 to December 2007, 138 implants placed in 56 elderly patients aged 65 years or older (38 male, 18 female; mean age = 69.4 ± 3.9 years) were evaluated retrospectively. Survival rates were investigated according to local factors as age, gender, general disease, cause of tooth loss, implant location, fixture diameter and length, bone quality, use of bone graft and prosthesis type.
Results
Following the completion of prosthodontic treatment, the range of follow-up was from 5 to 140 months. (mean period = 53.0 ± 33.0 months) Out of 138 implants in edentulous area of elderly patients, 133 implants were survived and 5 implants were failed. And 63 implants were excluded due to absence at follow up check during 5 years. Therefore, 5-year cumulative survival rate of implants was 94.9%.
Among local factors, bone quality (P=0.037) and prosthesis type (P=0.015) were significantly correlated with implant survival outcomes.
Conclusions
Within the limits of this study, implants in edentulous area of elderly patients can serve as a good long-term and predictable treatment modality to replace the missing teeth with few complications and low failure rates.
