Quizplus · Accepted Answer

The three classifications of impressions in dentistry are preliminary, final, and occlusal registrations. Preliminary impressions are taken for diagnostic purposes or to create a custom tray for more accurate final impressions. Final impressions are the accurate and detailed impressions taken for the fabrication of restorations or prosthetics. Occlusal registrations are taken to record the patient's bite relationship.
