# Clinical Outcomes and Complications of Dental Implants Placed and Restored by AEGD Residents: Up to 10-Year Retrospective Study

## TL;DR

This study shows that dental implants placed by AEGD residents under supervision have low complications and high patient satisfaction over up to 10 years.

## Contribution

The study provides new evidence on the clinical outcomes of dental implants placed by AEGD residents, comparing them to specialist standards.

## Key findings

- Only 8.4% of implants experienced screw loosening and 3.4% had crown issues.
- Diabetes and high plaque index were significant predictors of peri-implantitis.
- Over 80% of patients rated their outcomes as 8-10 on a 10-point scale.

## Abstract

Background: Implant therapy is a standard of care for long-term tooth replacement. While high survival rates have been reported for implants placed by specialists, data on outcomes achieved by Advanced Education in General Dentistry (AEGD) residents remain limited. Objectives: To evaluate the clinical performance and complication rates of dental implants placed and restored by AEGD residents under faculty supervision, and to identify factors influencing outcomes after at least one year in function. Methods: A retrospective review was conducted for implants placed between April 2012 and December 2021 at the Eastman Institute for Oral Health. Only implants with ≥1-year follow-up were included. Data included demographics, medical history, smoking status, oral hygiene, peri-implant health, and prosthetic outcomes. Logistic regression was used to assess associations between risk factors and complications. Results: Among 262 implants that survived ≥1 year, the complication rate was low: screw loosening occurred in 8.4%, crown issues in 3.4%, abutment or screw fractures in 0.4%, and early peri-implantitis in 11.5%. Examiner satisfaction was high for esthetics (82.8%) and occlusion (85.9%), and over 80% of patients rated their outcomes between 8 and 10 on a 10-point scale. Diabetes and high plaque index were significant predictors of peri-implantitis. Conclusions: Implants placed and restored by AEGD residents under structured faculty supervision achieved low complication frequencies, and strong patient satisfaction comparable to specialist outcomes.
