Abstract: Background: Trauma and chronic inflammation are controversial factors because of their potential role as
an initiator or as an aggravating factor in the oral carcinogenesis process. Dental implants are related to
chronic inflammatory processes and could act as a potential risk factor for oral cancer.
Objective: To analyze the oral cancer cases adjacent to dental implants.
Methodology: A PubMed database search on studies of oral cancers adjacent to dental implants was
conducted.
Statistical analysis: The descriptive statistic included means, standard deviations, ranges and percentages.
For the comparison of continuous variables, the Student's t-test was used and, for the comparison of
categorical variables the Pearson Chi-square test was applied.
Results: Thirty studies describing 62 cases of oral cancer adjacent to dental implants were included in this
review. These cancers were observed more frequently in patients with an average age of almost 67 years,
female gender and mandibular location. The most prevalent harmful habit was the combined consumption
of tobacco and alcohol and the most common oral risk lesion was leukoplakia. Almost all were oral
squamous cell carcinomas and half were moderately differentiated.
Conclusion: Oral cancers adjacent to dental implants seem to have similar characteristics than tumors not
related to dental implants.Keywords: Dental implantation, dental implants, epidemiology, mouth neoplasms
