Summary
Lesions around dental implants are uncommon but can be serious. Prompt histopathological analysis of peri-implant tissues is crucial for timely diagnosis and management of these oral conditions.
Area of Science:
- Oral pathology
- Dental implantology
- Histopathology
Background:
- Dental implants are a common solution for tooth replacement.
- Complications like lesions around implants can have severe consequences.
- Understanding the frequency and types of these lesions is vital.
Purpose of the Study:
- To evaluate the frequency of lesions associated with dental implants.
- To determine the microscopic types of these peri-implant lesions.
Main Methods:
- Retrospective cross-sectional study of 43 cases with lesions around dental implants (2013-2024).
- Data collected on demographics, lesion location, and histopathological diagnosis.
- Statistical analysis using SPSS with chi-squared, Fisher's exact, ANOVA, and T-tests.
Main Results:
- 1.18% (43/3641) of biopsies showed lesions around dental implants.
- Most frequent lesions were inflammatory/reactive (non-specific inflammation/peri-implantitis 39.5%, peripheral giant cell granuloma 14%).
- Oral squamous cell carcinoma was the most frequent malignancy.
Conclusions:
- Diverse lesions occur around dental implants, ranging in severity.
- Prompt histopathological analysis is recommended for peri-implant tissues, especially before surgical intervention.
- Early diagnosis aids in managing risks and ensuring patient health.
