Question 1

All-on-4 vs. implant dentures: which one is better?

Accepted Answer

Neither wins across the board. All-on-4 gives you fixed teeth on four implants and the strongest bite, implant dentures on more implants add support and cost and can be built fixed or removable, and snap-in overdentures cost roughly half as much nationally, need less bone, and are the easiest to clean. The research on the lower jaw finds fixed and removable designs both clinically successful, so your expectations and budget should decide.

Question 2

How many implants do snap-in dentures need?

Accepted Answer

Two implants in the lower jaw are the long-standing minimum standard of care, and most upper snap-ins are planned on four implants because the upper bone is softer and the denture is larger. More implants mean more stability and more cost.

Question 3

Is All-on-4 the same as implant dentures?

Accepted Answer

All-on-4 is a specific type of fixed implant denture: a full-arch restoration on four implants, with the back two angled. "Implant dentures" is the umbrella term, and in local advertising, it can mean a fixed All-on-6, a bar-supported denture, or a removable snap-in, so ask exactly what is being quoted.

Question 4

Can I switch from snap-in dentures to All-on-4 later?

Accepted Answer

Often, yes, if the original implants were placed with that in mind and your bone supports two more. The reverse is also possible: a fixed arch can usually be converted to a removable design if cleaning becomes difficult. Ask about conversion before your implants are placed, not after.

Question 5

Do All-on-4 teeth come out?

Accepted Answer

Not by you. All-on-4 is screwed onto the implants and stays in place day and night; your dentist removes it for maintenance. If you want teeth you can take out to clean, a snap-in overdenture or a removable bar denture is the design to ask about.

Question 6

Does Medicare cover All-on-4 or snap-in dentures?

Accepted Answer

Original Medicare does not cover dentures or implants in most cases. Some Medicare Advantage plans include dental benefits that may pay part of a denture, and private dental plans sometimes cover a portion of the denture piece of a snap-in, so request a pre-treatment estimate before you schedule.
