Purposes: Prosthesis-related Fibrous Hyperplasia, also many times referred as epulis fissuratum, is one of the most common benign oral soft tissue lesion, that appears due to chronic trauma, usually caused by a poorly adapted prosthesis. It is more common in the anterior region of the maxilla, being an exophytic lesion, which affects mainly elderly and female patients. Our aim is to present the usefulness of Er:YAG and Nd:YAG lasers in the surgical treatment of an Prosthesis-related Fibrous Hyperplasia (PRFH). Case report: The present paper reports a clinical case of two PRFH located in the maxillary vestibulum mucosa and in the palate in a 56-year-old female, caused by a poorly adapted prosthesis. For excision of the lesions in the vestibule and palate we used Er:YAG Laser (2940nm) and ND:YAG (1064nm), respectively. In the postoperative period, the patient did not report any discommodity, and presented a good tissue healing. Histological examination revealed the presence of Fibrous Hyperplasia. Conclusions: Elimination of PRFH is the treatment of choice with the confection of a new prosthesis. The two lesions were correctly eliminated, with the use of an Er:YAG and Nd:YAG lasers, with excellent recover and without recurrence.
