Types of denture base

Denture bases are commonly made from acrylic resin, cobalt-chromium metal, flexible thermoplastic resin, or combinations selected for the design.

The base supports artificial teeth and contacts oral tissues or remaining teeth. Acrylic resin is widely used for full dentures, cobalt-chromium creates a thin rigid framework for many partial dentures, and flexible thermoplastics suit selected removable designs.

The dentist chooses a base after examining the ridge, saliva, bite, remaining teeth, undercuts, and repair needs. Impressions or scans guide the laboratory, followed by try-in, insertion, pressure adjustment, and review.

Seek review if the denture rubs, causes a sore, clicks, slips, cracks, or changes speech or chewing. Do not keep wearing a damaged denture that injures the mucosa.

Ask why the material suits your ridge and remaining teeth, and ask about thickness, clasps, repair, relining, cleaning, removal at night, comfort, and stability.
