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

It is a fixed full-arch implant bridge supported by four implants in the classic concept. “Permanent” means you do not remove it yourself; it still needs maintenance and may need professional removal for service.

How many implants do snap-in dentures need?

The number varies by jaw, bone and design. Some lower overdentures use two implants, while other upper or lower designs use more for support and stability.

Can LOCATOR implants be made fixed?

Selected existing LOCATOR-compatible cases may qualify for LOCATOR FIXED after implant health, number, position, restorative space and component compatibility are verified.

Can I have teeth on implant day?

Some fixed cases qualify for a provisional restoration on surgery day. The final prosthesis usually follows healing, and immediate loading depends on implant stability and the clinical plan.

Full-arch choices in plain English

All-on-4 or snap-in dentures—which would fit my life better?

The biggest difference is not the marketing name. It is whether the teeth stay in, how you clean them, what your bone can support and what maintenance you are comfortable doing every day.

Full-arch implant restoration representing fixed and removable teeth options

Quick answer

Snap-in overdentures attach to implants but come out for cleaning. All-on-4 and other fixed bridges stay in and must be cleaned underneath. LOCATOR FIXED is another non-removable design that may use compatible existing or newly placed implants in selected cases. Bone, implant position, health, dexterity, cost and maintenance preference determine the realistic choices.

Start with your question

The everyday questions that decide the choice

Patients searching these terms are usually trying to picture eating, cleaning, repairs and whether they can upgrade later.

Will food get under fixed teeth?

A hygiene space is needed under many fixed full-arch bridges. Food and plaque can collect there, so water flossers, small brushes or floss threaders and professional maintenance matter.

Are snap-in dentures easier to clean?

They come out, which makes the denture and implant attachments easier to see and clean. They still need daily care and the clips or inserts wear over time.

Can I start removable and upgrade to fixed later?

Sometimes, but not every implant position or system converts. Planning the possible final destination before implants are placed preserves more options.

Does fixed mean maintenance-free?

No. Fixed bridges need daily cleaning underneath, regular exams and professional removal or repair when indicated. Implants can still develop inflammation.

Compare by tradeoff, not by slogan

No single design wins every category. A useful consultation explains where each option asks more from you.

Cleaning and dexterity

A removable denture can be cleaned in the hand. Fixed teeth require tools and access underneath the bridge.

Bone and implant position

Available bone, smile line, implant angle and existing implants limit which prosthetic designs can be made safely.

Feel, speech and palate coverage

Design thickness and palate coverage vary. A trial or provisional phase helps refine speech, bite and lip support.

Upfront cost and future service

Compare surgery, provisional and final teeth, attachment replacement, hygiene visits and repair—not only the advertised starting number.
