Abstract :
Objective: Whilst many questions and doubts still remain, today the use of dental im-plants has gained an increasing popularity amongst patients as well as dentists. The aim of this study is to analyze the survival rate in using such implants over a 10 year period.
Materials and Methods: In this study, 3050 ITI implants placed in 1000 patients with the mean age of 49.5 years (54.4% males and 44.6% females) during 1050 stages were evalu-ated for the survival rate. The present study is a descriptive, time based analysis of all the files of patients that have been treated using dental implants over a period of 10 years. General information, number of implants in each jaw, type of implant surface, type of edentulous area, time span of Prosthodontic therapy and the endurance of the implants were gathered.
Results: Incidence of failure was as low as 2% and the number of implant failures was 23 implants (0.7%). These failures were seen in 13 implants in the upper jaw of 12 patients and 10 implants in the lower jaw of nine patients. In other words, the comprehensive sur-vival rate was seen in 98% of the patients and 99.3% of the implants.
Conclusion: The use of dental implants in treatment of missing teeth is favorable regard-less of the subject’s age, sex and type of the edentulous area and a very high survival rate seems feasible.
