Abstract

Purpose:

The propose of this article was to evaluate the risk factors associated with the survival rate of the dental implants.

Material and Methods:

This retrospective study evaluated the survival rate of 940 implants placed at the Faculty of Dentistry, Department of Oral and Maxillofacial Surgery, Istanbul University, from January 2003 to January 2011. The potential risk factors associated with the survival rate of the implants were investigated.

Results:

Fifteen (1.5%) of the 940 implants failed during the follow-up period. Smoking did not affect the survival rate of the implants (log-rank, 1.5; P = 0.219). The survival rate of the implants placed in the maxilla was lower than that of the implants placed in the mandible (log-rank, 4.81; P = 0.028). The 5-year survival rate of the dental implants was 98.5%.

Conclusions:

There are still conflicting results about the risk factors associated with the survival rate of the implants. According to the results of this study, it is concluded that only the location of the implants is associated with the survival rates of the implants. All implant systems showed high survival rates.
