Abstract
This case report outlines a multidisciplinary surgical approach to vestibular deepening in a 62-year-old male with a severely resorbed edentulous maxilla and poor denture retention. To optimize the maxillary vestibular depth and prepare the arch for prosthetic rehabilitation, Clark's technique was utilized in the bilateral posterior region, while a diode laser-assisted periosteal release and frenectomy were performed in the anterior segment. These procedures enabled effective apical repositioning of the mucosa and muscle attachments without the need for grafting, thereby enhancing the extent of immobile mucosa essential for denture stability. Periodontal dressing was applied postoperatively to maintain vestibular depth and support tissue healing. The healing phase was uneventful, with notable improvement in vestibular depth and soft tissue quality, following which the patient was referred for final prosthetic restoration. This case highlights the clinical utility of combining traditional and laser-based vestibuloplasty techniques in managing challenging edentulous cases with limited vestibular depth.
