What characteristic does a positive reproduction refer to?

A positive reproduction refers to an exact fit, as it is created from a negative impression. A negative impression captures the contours and features of the oral cavity or dental structures, and the positive reproduction is formed to reflect that shape accurately. This allows for precise fitting of dental prosthetics, ensuring that restorations such as crowns, bridges, or dentures align perfectly with the patient's anatomy. The key aspect of this process is that the reproduction must mirror the original negative impression accurately, resulting in a representation that is functionally and aesthetically suitable for the patient.
