A Review of Functional Considerations in Removable Partial Denture Design

Abstract

Esthetics has become a critical determinant of success in removable partial denture (RPD) therapy, strongly influencing patient acceptance, comfort, and oral health–related quality of life. While RPDs have traditionally focused on restoring function and biomechanics, contemporary prosthodontic practice increasingly emphasizes natural appearance, particularly in esthetically sensitive regions. This review summarizes current concepts and evidence related to esthetic considerations in RPD design, encompassing patient-related and oral determinants, framework design principles, clasp selection and modification, precision and semi-precision attachments, and denture base and artificial tooth selection. Special attention is given to anterior edentulous situations, high smile line patients, and geriatric cases where implants may be contraindicated. Recent advances in biomaterials, CAD–CAM fabrication, and digital smile analysis are also discussed for their role in improving esthetic predictability and clinical outcomes. Overall, the literature supports a balanced, individualised, and patient-centered approach that integrates esthetics with functional efficiency, ensuring long-term satisfaction and clinical success of RPDs in modern prosthodontic practice.
