What this Trial Is About
This randomized controlled clinical trial aims to compare patient satisfaction and prosthetic complications associated with three types of immediate surgical obturators used in maxillectomy patients. A total of 24 patients with acquired maxillary defects will be randomly assigned to receive one of three obturator designs: (1) conventional obturators retained with clasps and wire, (2) resin 3D-printed obturators with printed clasps and palatal screws, or (3) metallic 3D-printed obturators with metal clasps and palatal screws. Patient satisfaction will be evaluated using the Obturator Functioning Scale (OFS), and postoperative complications such as discomfort, lack of retention, or mucosal irritation . The study seeks to determine whether digital fabrication and enhanced retention methods improve clinical outcomes compared to traditional approaches
