Acrylic with or without framework

In dental labs, “acrylic with or without framework” refers to prostheses made of acrylic resin. Without framework: Lightweight, affordable, and used for temporary dentures but less durable. With framework: Includes a metal base, offering better strength, fit, and durability, often used for partial dentures.

In a dental lab, “acrylic with or without framework” refers to the type of material and structure used in making dental prostheses like dentures or partials. Here’s a breakdown:

Acrylic Without Framework

  • Description: These are made entirely of acrylic resin.
  • Uses: Often used for temporary or transitional dentures, sometimes for full dentures.
  • Advantages:
    • Lightweight and affordable.
    • Easier to repair or adjust.
  • Disadvantages:
    • Less durable than metal-supported frameworks.
    • Prone to fractures or wear over time.

Acrylic With Framework

  • Description: These include a metal or rigid substructure (often cobalt-chromium or titanium) beneath or within the acrylic.
  • Uses: Common for removable partial dentures (RPDs).
  • Advantages:
    • Provides additional strength and stability.
    • Better fit and support due to the rigid framework.
    • More resistant to fractures.
  • Disadvantages:
    • More expensive and complex to fabricate.
    • Heavier than acrylic-only options.

The choice between the two depends on the patient’s needs, the dentist’s recommendations, and cost considerations.
