Annotation: Dental implant therapy has become a predictable and effective method for replacing missing teeth. The success of implant-supported prostheses depends not only on osseointegration but also on the design and characteristics of the prosthetic superstructure. Among the most commonly used restorative components are multi-unit straight abutments and milled abutments. These abutments serve as intermediate structures between implants and prosthetic restorations, influencing biomechanics, esthetics, passive fit, and long-term clinical outcomes. This article presents a comparative analysis of multi-unit straight abutments and milled abutments based on prosthetic design, biomechanical performance, clinical applications, esthetic considerations, maintenance requirements, and treatment outcomes.
