All-on-4, 5, 6, or X Dental Implants: What Do They Mean?

Modern Day Smiles • February 11, 2025

Understanding Your Options for Full-Arch Restoration

For patients missing most or all of their teeth, All-on-X dental implants provide a permanent, stable alternative to traditional dentures. The number in All-on-4, All-on-5, or All-on-6 refers to the number of implants placed in the jawbone to support a full-arch prosthetic, ensuring long-term functionality and bone preservation.

What Is the Difference Between All-on-4, All-on-6, and All-on-X?

  • All-on-4: Four implants support the prosthetic teeth
  • All-on-5 or 6: More implants provide additional stability
  • All-on-X: Custom treatment based on the patient’s bone density and specific needs


Choosing the right implant solution depends on a professional evaluation of jawbone health and long-term functionality, ensuring the best fit for each patient.

Benefits of Additional Implants in Full-Arch Restorations

While All-on-4 implants are a widely used solution, additional implants (All-on-5 or All-on-6) provide even greater stability and longevity. Some key advantages of extra implants include:


  • Increased Bite Force – More implants distribute pressure evenly, allowing patients to eat a wider variety of foods.
  • Enhanced Bone Stimulation – Additional implants prevent jawbone shrinkage more effectively by maximizing bone engagement.
  • Greater Prosthetic Support – More implants reduce the risk of wear and tear, extending the lifespan of the restoration.
  • Ideal for Patients with Stronger Bone Structure – Those with sufficient bone density may benefit from more implants for maximum security and durability.


Our team at Modern Day Smiles personalizes each All-on-X treatment plan to ensure optimal function, comfort, and aesthetics.
