Final answer:
A dental restoration fabricated on a replica of a patient's teeth should be non-destructive and reversible to ensure conservation of the original teeth and accommodate future advancements in dental restoration methods.
Step-by-step explanation:
If a restoration is fabricated on a replica (positive reproduction) of a patient's teeth, it is referred to as a dental restoration or prosthetic. A key point about restorations is that they should be non-destructive and reversible. This ensures the conservation and safety of the original structure. The reversibility of restorations allows for the possibility of future advances in restoration methods to be applied without damage.
