Acrylic dentures - step by step

What are the steps to make normal dentures, or to fit them into implants? First, a mould (impression) has to be made using a viscous paste (alginate) in a custom tray with the form of the dental arch. The mould thus obtained is like the "negative" of a photo. To obtain the positive, it is filled with plaster and allowed to harden.

From that moment we now have a model just like the mouth. On the model, a base is made with wax (stabilized with acrylic) to take some important anatomical records through a test. In the next step, the teeth are mounted in wax and a new test is conducted.

During the try-in, the patient can see if he or she likes or wants any changes in color, shape and position of the teeth. The dentist assesses good adaptation and technical details. After this last test, the work goes through a process where the wax is removed and replaced by the definitive material, usually acrylic polymer. It may also be made of nylon or silicone, making it more expensive in such cases.
After that the acrylic is polymerized at heat and it stiffens. The prosthesis is then polished and finally placed in the mouth and the patient pays for the value of it only at that time. It is normal to have to return to the clinic to fine tune some detail.

Sometimes people ask if there is clear acrylic. Yes there is! The base of the dentures can take this type of resin, but it actually looks better in the natural tone of the gums. Various shades are available in the market for people of all ethnicities.
