  • Compare the success of implants and NSRCT, with minimal subjective grading.


  • N= 129 implants, 143 NSRCT.
  • Implant data collected from a Periodontic practice, and RCTx data collected from Endodontic practice. Outcome was determined by clinical chart notes and radiographs. Followed up an average of 36 months. Failure was defined as removal of the implant or tooth. Success was recorded if the implant or tooth was in place and functional.


  • Implant success rate of 98.4%.
  • NSRCT success rate of 99.3%.
  • No statistically significant differences were found
  • When uncertain findings were added to the failures, implant success dropped to 87.6%, and endodontic success declined to 90.2%. (difference not SS)
  • 12.4% of implants required interventions, whereas 1.3% of endodontically treated teeth required interventions – statistically significant

Clinical Significance:

The success of implant and endodontically treated teeth was essentially identical, but implants required more postoperative treatments to maintain them
