Functional wax up is the concept of finished work that has to fully and realistically fulfill the function and aesthetics.
With this wax up we have developed the concept of complete functional and aesthetic rehabilitation of the upper and lower jaw. Only after this test we will get precise information on how we should access the making of a prototype or temporary work that precedes the definitive solution.
Thus, when handing over the work to the patient, there is no unknown for us or for the patient because all the potential problems are resolved.
