What Is All-on-4 and All-on-6 Treatment?

If you are considering full arch implants, you will likely hear these terms. Here is what they mean.

All-on-4 and All-on-6 are specific techniques for replacing all teeth in one jaw using a fixed bridge supported by implants.

  • All-on-4:
  • Uses 4 strategically placed implants
  • The two front implants are placed straight (vertical)
  • The two back implants are placed at an angle (tilted) to make contact with denser bone
  • The angled design often avoids the need for bone grafting or sinus lifts
  • The entire arch of 10–12 teeth is attached to these 4 implants on the same day (in many cases)
  • Most popular option for full arch restoration
  • All-on-6:
  • Uses 6 implants placed in a straight line
  • Provides more support and stability than All-on-4
  • Requires more bone than All-on-4
  • Better suited for people with adequate bone density
  • May still allow same-day teeth

Which Is Right for You?

  • All-on-4 may be better if:
  • You have significant bone loss
  • You want to avoid bone grafting
  • You have a smaller jaw
  • All-on-6 may be better if:
  • You have good bone density
  • You want extra stability and support
  • You have a larger jaw size

Key Benefits of Both

  • Fixed teeth β€” do not remove them
  • Same-day teeth (often) β€” walk out with teeth on the day of surgery
  • Eat most foods normally
  • Natural appearance
  • Prevents further bone loss
