The goal of this clinical trial is to learn whether different palatal rugae designs in complete dentures can improve comfort, function, and overall oral health-related quality of life in edentulous adults aged 40 to 80 years. The main questions it aims to answer are:
Do roughened or vacuum-formed thermoplastic sheet palatal rugae designs lead to higher patient satisfaction than the traditional polished design?
Do these designs improve oral health-related quality of life, including chewing, speaking, and overall comfort?
Researchers will compare three denture designs-a polished palatal surface, a roughened palatal surface, and a vacuum-formed thermoplastic sheet rugae design-to see which design provides better comfort, function, and quality of life for patients.
Participants will:
Receive complete maxillary dentures made with one of the three palatal rugae designs
Attend follow-up assessments at 1 week, 1 month, and 3 months after denture insertion (in person or by phone)
Complete the OHIP-EDENT questionnaire and a Visual Analog Scale (VAS) to report satisfaction, comfort, and oral health-related quality of life.
