BRABYN, Philip J.; NAVAL, Luis; ZYLBERBERG, Ian  and  MUNOZ-GUERRA, Mario Fernando. Oral squamous cell carcinoma after dental implant treatment. Rev Esp Cirug Oral y Maxilofac [online]. 2018, vol.40, n.4, pp.176-186. ISSN 2173-9161.  https://dx.doi.org/10.1016/j.maxilo.2018.02.003.

Peri-implantitis is an inflammatory response of the soft tissue surrounding osteointegrated implants. Squamous cell carcinoma can be sometimes confused clinically with peri-implantitis, and there have been various cases published of squamous cell carcinoma development in areas surrounding dental implants.

Between 2008 and 2017, 6 cases of SCC surrounding implants were reported. 66.6% had a previous history of OSCC and association with risk factors (tobacco or alcohol consumption) was present in three patients.

A literature search retrieved 54 cases (25 articles) published between 1996 and 2017. 42.6% of the patients had a previous history of OSCC, 42.6% of them also had risk factors, and 51.9% of the patients had some type of pre-malignant lesion. Of the 18 patients that had no past oncological history or pre-malignant lesion (33.3%), 8 of them did not have any risk factors either.

The incidence rate of oral squamous cell carcinoma surrounding implants seems to be higher in patients with previous oral tumors. Therefore, a close follow-up of these at-risk patients (tobacco or alcohol consumption, or previous history of cancer) should be carried out, especially those that present peri-implantitis.
