Prosthetic rehabilitation associated with the use of high-power laser following pelveglossectomy and radiotherapy for oral squamous cell carcinoma: A clinical report.

This clinical report documented the prosthodontic rehabilitation of a 70-year-old man with extensive postoperative sequelae (fibrosis and mucosal adhesions) following pelveglossectomy and radiotherapy for oral squamous cell carcinoma. To overcome severe anatomic limitations impeding oral rehabilitation, a multidisciplinary protocol was implemented featuring 10 surgical sessions using a 980-nm diode laser for minimally invasive procedures, including fibrotic band release, adhesion reduction, and vestibular sulcus deepening (vestibuloplasty). Custom surgical and healing guides were essential to manage tissue remodeling and establish a favorable basal seat area for the definitive prostheses. The successful laser-assisted intervention allowed for the fabrication and insertion of complete dentures. The outcome included significant improvement in masticatory efficiency, speech, and facial esthetics, enhancing oral health-related quality of life (OHRQoL). The early involvement of the maxillofacial prosthodontist and the strategic use of high-power laser (HPL) therapy were determined to be critical for successful prosthetic rehabilitation in complex treatments after oncologic interventions.
