  • Step 1: After the wax try-in has been verified by the dentist, Kolbeck transfers the case to a new working silicone matrix model. To fabricate the model, he uses a rubber base and a firm silicone lab putty material for strength and accuracy, and makes sure all screws are totally seated into the new working model.
