Background:
The atrophy of the prosthetic base may result in the loss of both retention and stabilization of the removable prosthetic restorations. As a result of prolonged mechanical injury caused by the edge of the removable prosthetic restoration, a lesion called inflammatory fibrous hyperplasia – granuloma fissuratum – can develop.

Aim of the study:
The paper describes granuloma fissuratum in a patient using removable prosthetic restorations, and rehabilitation procedures.

Discussion:
Granuloma fissuratum occurs in 5-14% of removable dentures users. Most cases are detected in women. The longer the period of use of the same dentures, as well as their circadian use, the higher the risk of developing granuloma fissuratum. The new prosthetic restoration may initially cause a gag reflex. If persistent and intensive, gag reflex leads to avoidance of control visits at the dentist, insufficient oral hygiene and, as a consequence, faster loss of the remaining teeth. The treatment of granuloma fissuratum can be conservative or surgical. It is believed that laser surgery should be the standard for removing granuloma fissuratum.

Conclusion:
A prosthetic restoration should be a therapeutic and rehabilitation device, not an iatrogenic traumatic factor within the stomatognathic system.
