Introduction: Retention is a critical factor in the success and functionality of maxillofacial prostheses, directly influencing patient comfort, prosthesis stability, and overall treatment outcomes. Maxillofacial defects, whether congenital, acquired, or developmental, often present complex anatomical and biomechanical challenges requiring specialized retentive solutions. Methods: Various retentive aids are used to achieve optimal prosthesis stability, including mechanical, anatomical, adhesive, and implant-assisted techniques. Mechanical aids such as clasps and magnets, anatomical undercuts, tissue adhesives, and osseointegrated implants have been widely utilized. Recent advances in digital technologies and materials have led to precision attachments and customized implant abutments that enhance prosthetic adaptation and esthetics. Results: This case series illustrates the comparative application of different retentive strategies in extraoral maxillofacial prostheses. Each case highlights the role of prosthesis design, tissue support, and interprofessional collaboration in achieving optimal retention and patient satisfaction. Conclusions: Effective retention in maxillofacial prosthetics depends on individualized case selection, biomechanical understanding, and technological integration. The synergy between conventional and modern retention techniques ensures superior functional and esthetic rehabilitation for patients with facial defects.
