Abstract
Purpose: The aim of this study was to retrospectively investigate the survival rate and the influencing factors of narrow implants less than 3.5 mm in diameter.
Materials and Methods: Included this study were the patients who received the implantation from January 1995 to December 2011 and visited the Department of Periodontology, Dental Hospital of Yonsei University after over 12 months from the time of their implantation. The cumulative survival rate was calculated and various factors affecting the rate were investigated according to the implant system, gender, age, implant position, length, and splinting. The causes of failed implants were also analyzed.
Results: The overall survival rate was 98.6% and 11 implants were removed. There was no statistically significant differences among the survival rate according to the implant system, gender, position, length and the existence of splinting. The most frequent/common reason for failure was infection, which was responsible for 8 out of 11 failed implants.
Conclusion: In conclusion, the present study suggests that the use of narrow diameter implants can be a predictable treatment option.
