Acrylic vs. Cast vs. Flexible Partial Dentures: A Complete Guide

If you're missing some — but not all — of your teeth, a partial denture fills the gaps. There are three main types, and the right one depends on your priorities. Here's how they compare.

Acrylic partial dentures

A acrylic partial has teeth set into a pink acrylic base, often with metal clasps. It's the most budget-friendly option and easy to add to if you lose more teeth later.

• ✔ Most affordable; great as a transitional or healing denture
• ✔ Simple to adjust and repair
• ✖ Bulkier than the alternatives

Cast metal partial dentures

A cast partial uses a slim, precision cobalt-chrome metal framework. It's the gold standard for durability and fit.

• ✔ Thin, strong, and long-lasting
• ✔ Transfers bite force efficiently; less bulky on the palate
• ✔ Best long-term investment for most patients
• ✖ Metal clasps may show depending on placement

Flexible partial dentures

A flexible partial is made from a thin, gum-coloured nylon material with no metal clasps — so it's the most discreet and comfortable.

• ✔ Nearly invisible; no metal
• ✔ Lightweight and comfortable
• ✖ Harder to reline or add to later

Which should you choose?

Choose acrylic for budget or a transitional plan, cast metal for the best long-term durability and fit, and flexible for the most natural, metal-free look. At Dentures Direct we make all three digitally in our own lab — and we'll recommend the one that truly fits your mouth and your goals, not the most expensive one.
