Objectives: Retention is a critical factor in the success and functionality of maxillofacial prostheses, directly influencing patient comfort, prosthesis stability, and overall treatment outcome. Methods: Maxillofacial defects, whether congenital, acquired, or developmental, often present unique anatomical and biomechanical challenges that necessitate the use of specialized retentive aids. Results: These aids include mechanical, anatomical, adhesive, and implant-assisted methods, each with distinct advantages and limitations. Mechanical aids such as clasps and magnets, anatomical undercuts, tissue adhesives, and Osseo integrated implants are commonly employed to enhance prosthesis retention. Recent advancements in material science and digital technologies have also enabled the integration of precision attachments and custom-designed implant abutments, offering improved aesthetics and functionality. Conclusions: The present case series highlights the various retentive strategies used in extraoral maxillofacial prosthesis, with emphasis on case-specific selection, multidisciplinary collaboration, and emerging trends that optimize prosthesis retention and patient rehabilitation.
