What is Denture Base Resin

Denture base resin refers to the material used to fabricate the base of a denture, which holds the artificial teeth in place and fits snugly over the gums. The most common type of denture base resin is polymethyl methacrylate (PMMA), although other materials can also be used depending on specific needs. Here’s a brief overview:

1. Polymethyl Methacrylate (PMMA)

Most commonly used: PMMA is the most widely used material for denture bases due to its excellent physical and aesthetic properties.
Advantages:

  • High strength and durability
  • Relatively inexpensive
  • Aesthetic and available in various shades to mimic gum tissue
  • Biocompatible (non-toxic for oral use)

Disadvantages:

  • Susceptible to fracture under high stress
  • May shrink slightly during polymerization, requiring precise craftsmanship
  • Can absorb odors and stains over time

2. Light-Cured Denture Base Resin

Application: Used for relining or repair of existing dentures, or for creating provisional denture bases.

Advantages:

  • Quick polymerization with light curing units
  • Reduced shrinkage compared to PMMA

Disadvantages:

  • Not as durable for long-term use compared to PMMA

3. Flexible Denture Base Resin

Material: Often made of nylon or other thermoplastics.

Advantages:

  • Flexible and comfortable
  • Good for patients who are sensitive to PMMA
  • Resistant to fracture due to flexibility

Disadvantages:

  • Difficult to adjust or repair
  • May not be as stable as PMMA bases

4. High-Impact Denture Base Resin

Application: Designed to withstand higher levels of impact and reduce the risk of fractures.

Advantages:

  • Stronger than conventional PMMA
  • Increased resistance to breakage

Disadvantages:

  • More expensive than standard PMMA

Processing Techniques:

  • Heat-Cured: Typically stronger and more stable due to better polymerization.
  • Self-Cured/Cold-Cured: Easier and quicker to use but may not have the same strength or longevity as heat-cured resins.

The denture base resin offered by Medicafast is a CAD/CAM material designed for dental laboratories to create high-quality denture bases efficiently. This resin has a high degree of polymerization, resulting in reduced monomer residue, which contributes to less water absorption and dissolution. It also contains bionic fibers, providing superior aesthetics by mimicking natural gum tissue more effectively. This makes it ideal for creating strong, durable, and aesthetically pleasing dentures. Medicafast’s denture base resin stands out due to its ability to offer both functional durability and visual appeal for dental prosthetics​(Medicafast
