Following is a transcript of the video:
Narrator: Dentures. They’re often used as comic relief in movies and Pixar animated shorts, but they play a big part in the daily lives of about 20 million people in America, and it’s not just older people wearing them.
But how exactly are they made?
Dentures have come a long way. This set took two fittings and was shipped between two locations before it was ready to wear.
The first thing to know is that a full set of dentures has a flesh-colored acrylic base that fits over the gums. The upper portion covers the roof of your mouth, and the lower is a horseshoe shape that accommodates the tongue.Now that we know the basics, let’s learn how dentures are made.
First, a dentist makes an impression to capture the patient’s upper and lower gums. A thick paste gets placed into the patient’s mouth for a few seconds.
While the impression is still gooey, it’s poured into a stone, which acts as a cast. This cast is now a replica of the patient’s mouth, which comes in handy during the final stages of creating the dentures.In the meantime, the patient tries on different sets of dentures to determine the size and color of their soon-to-be teeth.
From there, the dentist makes a few adjustments to the cast.
Next, the cast of the mouth is sent to the lab where the dentures get made. Using the patient’s cast as reference, the lab starts to create the wax version of the gum line. The teeth, made of acrylic resin – a material that looks very similar to real teeth – are set in place. Minor touches get made to the wax around the teeth then get sent back to the dentist.
After the wax dentures are approved by both the patient and the dentist for fit and look, they’re sent back to the lab to finish the process.
The wax is just temporary. It gets replaced by an acrylic, which is more aesthetically pleasing and realistic-looking. The lab boils the dentures to get rid of the wax portions. Holes are indented into the teeth so the material can attach to it. Then, a machine called the IvoBase injects the acrylic liquid into the molds to stick to the denture teeth.
The dentures are cleaned up and polished. They’re now ready for the patient.
