Wax Up is made from an imprint, the dentist will abrade the gypsum teeth to stumps, and will send that casting to the technician lab where the future crown and bridge are molded from wax. This wax is also a very helpful tool for the patient, as they can see how the final denture would be, and it also provides information to the dentist for the abrasion and the need for space. Together with the patient, the wax model can be corrected until it becomes satisfactory, and the work starts only afterwards, knowing precisely the patient’s needs and demands.
