Summary
Dental implant survival rates were high (92.8% at 5 years) in a teaching program. Perioperative bone grafting was linked to increased implant failure risk, highlighting its importance in surgical planning.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Implantology
- Surgical Outcomes Research
Background:
- Evaluating surgical outcomes and survival rates of dental implants.
- Focus on implants placed within a multidisciplinary teaching program setting.
Purpose of the Study:
- To assess the success of dental implants placed by trainees in a teaching hospital.
- To identify factors influencing implant survival rates.
Main Methods:
- Retrospective review of 236 implants placed in 105 patients over 6 years.
- Minimum 6-month follow-up with survival defined by integration and position.
- Kaplan-Meier analysis and Cox proportional hazards models for survival analysis.
Main Results:
- Implant survival rates were 94% at 1 year and 92.8% at 5 years.
- Perioperative bone grafting was the only significant factor associated with increased implant failure.
- Implant age, smoking, site, anesthesia, timing, size, and comorbidities did not impact survival.
Conclusions:
- Satisfactory dental implant survival rates were achieved in a tertiary teaching center.
- Perioperative bone grafting significantly increases the risk of dental implant failure.
