AB  - BACKGROUND: Dental implants are a predictable treatment option for replacing 
      missing teeth and have strong survival and success outcomes. However, previous 
      research showed a wide array of potential risk factors that may have contributed 
      to dental implant failures. The objectives of this study are to study if implant 
      survival rates were affected by known risk factors and risk indicators that may 
      have contributed to implant failures. The secondary outcome measures were whether 
      the level of expertise of the periodontal residents affected success rates and 
      how the rate of implant success at the Harvard School of Dental Medicine (HSDM) 
      compared to published standards. METHODS: A retrospective chart review of 
      patients at the HSDM who had one of two types of rough-surface implants (group A 
      or B) placed by periodontology residents from 2003 to 2006 was performed. 
      Demographic, health, and implant data were collected and analyzed by multimodel 
      analyses to determine failure rates and any factors that may have increased the 
      likelihood of an implant failure. RESULTS: The study cohort included 341 dental 
      implants. The odds ratio for an implant failure was most clearly elevated for 
      diabetes (2.59 implant surface group B (7.84), and male groups (4.01). There was 
      no significant difference regarding the resident experience. The success rate for 
      HSDM periodontology residents was 96.48% during the 4-year study period. 
      CONCLUSIONS: This study demonstrates that implant success rates at HSDM fell 
      within accepted published standards, confirmed previously identified risk factors 
      for a failure, and potentially suggested that other acknowledged risk factors 
      could be controlled for. Furthermore, the level of experience of the 
      periodontology resident did not have an impact on survival outcomes.
