Evaluations of Endosseous Dental Implant Success Rates, Adverse Events, and Associated Risk Factors: A Retrospective
Summary
This study analyzed dental implant clinical performance, finding soft tissue complications like peri-implantitis were most common. Overall implant failure rates were low, but long-term follow-up is key for managing complications.
Area of Science:
- Dental Implantology
- Biomaterials Science
- Clinical Dentistry
Background:
- Dental implants are a common solution for tooth replacement.
- Understanding clinical performance and failure rates is crucial for improving patient outcomes.
- Factors influencing implant success require thorough investigation.
Purpose of the Study:
- To evaluate the clinical performance of dental implants.
- To determine surgical and prosthetic failure rates.
- To identify correlations between implant complications and patient/procedure factors.
Main Methods:
- Retrospective cohort study of 1,282 implants in 732 adult patients.
- Data collected from January 2016 to October 2021.
- Analysis included patient demographics, medical history, implant details, and complications.
Main Results:
- Overall adverse event rate was 7.5 per 100 person-years.
- Implant failure rate: 1.6/100 person-years; mechanical complications: 3.3/100; soft tissue complications: 3.6/100.
- Peri-implantitis (2.6%) and peri-implant mucositis (7.2%) were the most frequent soft tissue complications.
Conclusions:
- Soft tissue complications, including peri-implantitis and peri-implant mucositis, are the most common issues.
- These complications appear to be associated with the length of patient follow-up.
- While overall failure rates are low, ongoing monitoring is essential.
