Retentive Aids in Maxillofacial Prosthodontics: A Comprehensive Review

Abstract

Maxillofacial prostheses are artificial substitutes used to restore form and function in patients with maxillofacial defects. Retention is a critical factor in the success of maxillofacial prostheses. The stability and functionality of these prostheses can be enhanced by using retentive aids. tics. Increased retention improves comfort as well as the confidence in the patient while wearing a facial prosthesis at work and in social settings The challenges posed by varying defect sizes, tissue quality, patient factors, and aesthetics make the selection of appropriate retentive aids complex. This review summarizes the types of retentive aids (anatomic, mechanical, chemical, surgical/implant-based), their technical features, clinical applications, advantages, limitations, recent advances, and future directions. Evidence from literature up to 2024 is synthesized to aid practitioners in decision-making.
