Relationship between oral cancer and implants: clinical cases and systematic literature review - PDF

Between 3 and 5% of all malignant tumors are located in the head and neck region. Approximately half of these are located in the oral cavity, and oral squamous cell carcinoma (OSCC) accounts for roughly 90% of the total. It is defined as a malignant neoplasm which originates in the stratified epithelium, and is typically found in men over the age of 60, who have a habit of tobacco
and alcohol use.

However, this trend has been changing and is being observed more and more so in patients who are under the age of 40, even in children, adolescents, and in women who do not have any risk factors. It has also been associated with other less typical risk factors such as: the existence of nutritional deficiencies, exposure to ionizing radiation, immunosuppressant and irritant factors of dental and/or implant origin.

Oral rehabilitation using osseointegrated dental implants has become one of the best options for the treatment of edentulous patients and is considered by some to be the only form of treatment. Due to the universality of the use of dental implants, the literature has also reported an increase in the number of complications associated with their use. Among such complications, the most frequent are the inflammatory processes that affect the bone and soft tissues, which are known as peri-implantitis. Clinically, these conditions often occur with edema, erythema, hypertrophy and even ulcers of the soft tissues, sometimes presenting an appearance which may require a differential diagnosis with malignant lesions...
