PEEK FRAME vs. METAL FRAME – What’s the Difference?

A PEEK FRAME

A METAL FRAME

When it comes to frameworks for removable prosthetics or implant-supported structures, choosing the right material matters. Two commonly used options are PEEK (Polyether Ether Ketone) and Metal (usually Cobalt-Chrome or Titanium). Each has its own strengths, depending on the clinical case..

PEEK FRAME

✅ Biocompatible & Lightweight

PEEK is a high-performance medical-grade polymer, much lighter than metal. Offers excellent comfort for patients, especially in large frameworks.

✅ Metal-Free Alternative

Ideal for patients with metal allergies or sensitivities.
Non-conductive and radiolucent (won’t interfere with X-rays).

✅ Shock-Absorbing

Slightly flexible, providing cushioning during function.
Helps reduce stress on implants and bone.

✅ Aesthetics

Naturally tooth-colored or off-white — easier to mask under pink or tooth-colored materials.

❗ Limitations:

Lower strength than metal for thin designs.
Needs proper bonding protocol with veneering materials.

METAL FRAME

✅ High Strength & Rigidity

Offers strong support for thin, minimal designs.
Long-proven in full arch prosthetics and precision attachment work.

✅ Excellent Longevity

Durable and time-tested in both removable and fixed restorations.

✅ Precise Fit

Excellent for implant bar restorations and telescopic systems.
