Risk Factors for Early Dental Implant Failure
The International Journal of Oral & Maxillofacial Implants
|February 28, 2024
Summary
Younger, male, and smoker patients experienced higher early dental implant failure rates. Mandible placement and certain implant systems also showed increased risk, though the overall early failure rate was low.
Area of Science:
- Dental Implantology
- Oral Surgery
- Prosthodontics
Background:
- Early implant failure (EIF) is a critical concern in dental implantology.
- Identifying risk factors is crucial for improving treatment outcomes and patient satisfaction.
Purpose of the Study:
- To determine the prevalence of early implant failure (EIF) in dental implants placed at a teaching clinic.
- To identify patient- and implant-related risk indicators for EIF to enhance predictive accuracy and preventive strategies.
Main Methods:
- A retrospective analysis of 1,005 dental implants placed between 2011 and 2018.
- Definition of EIF as implant loss before functional loading.
- Data collected from operation logbooks and patient records.
Main Results:
- The overall early failure rate (EFR) was 5.4% (54 out of 1,005 implants).
- Increased risk for EIF was observed in smokers, men, and younger patients.
- Higher EFR noted for anterior maxillary implants and implants in the posterior mandible compared to posterior maxilla. Certain implant systems (Nobel Biocare) showed higher EFR.
Conclusions:
- Younger age, male gender, and smoking are significant risk factors for early dental implant failure.
- Implant location (mandible) and specific implant systems are associated with varying EIF rates.
- Despite identified risk factors, the overall EFR of 5.4% suggests a generally successful treatment protocol.
