Implants Success Rate in a Dental School Setting

Materials and Methods: Retrospective chart review of all patients (n = 305) from 1991-2004 who have had implants placed at the dental school. Five hundred fifty-eight implants (Nobel–Biocare-382 implants and Astra-Tech ) were placed by faculty, and restored by graduate and undergraduate dental students during that period. Patient age range was 18-82 years and the study was approved by the University IRB.

Results: A total of 155 patients had 382 Nobel Biocare (NB) implants from 1991-2004 and 150 patients had 176 Astra Tech implants from 2000-2004. The patients with Nobel Biocare implants with more that 10 years of placement showed a success rate of 97% and a 5-year success rate of 92%. The placement of Nobel Biocare implants increased by 50% in the 13-year period of study.

Conclusions: The results show that implant success rate in a dental school setting is similar to what is reported in the private dental practice and an overall increase in implant placement.
