title: Clinical effectiveness of International Team for Oral Implantology dental implant treatment in Taiwan: a seven-year longitudinal study.
abstract: BACKGROUND
  International Team for Oral Implantology (ITI) dental implant has been clinically tested for the most parts of the world, especially in Europe and America, and has not been conducted on Asian population. The purpose of this study was to evaluate the cumulative survival and success rates over 7 years of ITI dental implants.
  
  
  METHODS
  The ITI dental implant system has been used in the Dental Department of Chi Mei Medical Center since August of 1997. At the end of 2005, 717 solid-screw implants had been placed and loaded at least 6 months in 316 patients. The patient population included 145 males and 171 females, with a mean age of 43.18 +/- 11.60 years. The follow-up interval was from 6 months after the prosthesis was completed to 7 years. The success criteria of dental implant survival was based on Buser et al, Clin Oral Implants Res. 1990;1:33-40.
  
  
  RESULTS
  Most implants (486, 67.8%) were placed in the mandible and 231 (32.2%) were placed in the maxilla. Two implants were removed before prostheses fabrication because of postsurgical infections. One implant was removed due to a periapical infection of an adjacent natural tooth. The life table analysis of survival rate and success rate were 99.58% and 96.13%, respectively.
  
  
  CONCLUSIONS
  This 7-year clinical effectiveness study demonstrated this dental implant system gave a clinical reliable result in a Taiwanese population.
