Objective:
To determine whether dental implants impress oral lesions, and to evaluate the nature of their effect on the lesions.
Materials And Methods:
A comprehensive search was done via Google and PubMed for articles (including case reports and literature reviews) containing the keywords 'oral squamous cell carcinoma' (OSCC), 'oral lichen planus' (OLP), 'lichenoid contact reaction' (LCR), 'osseointegrated implants', and 'dental implants' , in the last 10 years (2002-2012).
Results:
The study included 24 articles involving patients with dental implants, and some oral lesions (e.g. oral lichen planus and oral squamous cell carcinoma) or with a history of lesions. In these publications, there is evidence suggesting the possibility of emergence, exacerbation, recurrence, or even malignant transformation of the oral lesions after implant placement in some cases.
Conclusion:
Based on our review of the literature, implant treatment does not seem to be completely safe under any circumstances, but may have some complications in subjects with certain diseases (e.g. oral lesions, autoimmune diseases, malignancies, allergic reactions, etc.). Therefore prior to treatment, patients should be fully informed of the risks.
Clinical Significance:
Implant treatment is best done with caution in patients with cancer or mucocutaneous disorders.
