Primary oral squamous cell carcinoma arising around dental osseointegrated implants mimicking peri-implantitis.

Prosthodontic rehabilitation using dental implants has become a common practice in dentistry at the present time. The number of complications related to dental osseointegrated implants has increased according to the generalization of its use along the last decade. Among the most common of these complications are chronic inflammatory conditions affecting both hard and soft tissues around dental implants. Although severe complications are uncommon, in recent years several cases of oral squamous cell carcinoma adjacent to dental implants have been published. In this paper we present a new unusual case of primary oral squamous cell carcinoma arising around a dental fixed prosthesis over osseointegrated implants in a 76 male patient with no previous history of malignance and no risk factors related to oral cancer.
