Risk Factors for Dental Implant Failure in Private Practice: A Multicenter Survival Analysis
The International Journal of Oral & Maxillofacial Implants
|April 28, 2021
Summary
Dental implant survival rates are high, with an 86.4% probability at 10 years for patients under 70. This study analyzed patient factors influencing implant failure in private practice settings.
Area of Science:
- Dental Implantology
- Biomaterials Science
- Public Health
Background:
- Dental implant failure can be influenced by patient-specific factors.
- Understanding these factors is crucial for improving long-term implant success rates.
- Previous studies have explored various risk factors, but data from private practice settings are less common.
Purpose of the Study:
- To quantify the probability of dental implant failure over time.
- To assess the impact of intrinsic patient factors on implant survival.
- To analyze data from a large cohort in multiple private dental practices.
Main Methods:
- Retrospective, multicenter cohort study design.
- Analysis of 835 implant-level records from 378 patients.
- Cox proportional hazards models used to evaluate age, sex, diabetes, smoking, and arch location.
Main Results:
- The 10-year implant survival probability for patients ≤ 70 years is 86.4%.
- No statistically significant increase in implant failure hazard ratios was found for sex, smoking, diabetes, or arch location.
- Mean follow-up was 23.1 months, with a maximum of 17 years.
Conclusions:
- Dental implant survival is high in routine private practice for patients ≤ 70 years.
- Effective clinical decisions and follow-up protocols may mitigate the impact of systemic risk factors.
- Further research should explore the interplay between patient factors and clinical management.
