Correct answer: A — To visualise and evaluate the planned restoration in three dimensions before tooth preparation
A diagnostic wax-up is the addition of wax to a study cast to simulate the planned final restorations in three dimensions. It allows the dentist and patient to evaluate aesthetics, tooth contour, occlusion, and phonetics before committing to irreversible tooth preparation. It also serves as a template for fabricating provisional restorations (using a silicone putty index), surgical guides, and communication with the dental laboratory. It is an essential step in complex restorative and prosthetic treatment planning.
