When each is the right answer.
Most implant practices push fixed full-arch as the default, and for good reason. A fixed prosthesis is what most patients picture when they imagine “teeth like the real thing.” It restores the most function. It looks the most natural. It carries the highest fee, which is rarely the surgeon’s motivation but is worth naming honestly.
For most patients, fixed is the right answer. For some patients, it isn’t. The real clinical reasons removable-but-stable can be the better call:
- Hygiene access. Cleaning under a fixed prosthesis is mechanical and relentless: a water flosser, interdental brushes, daily attention. Patients with manual dexterity issues, high peri-implant disease risk, or simply less appetite for the daily routine do better with a prosthesis they can remove and clean outside the mouth.
- Bone. Fixed full-arch needs four to six implants in adequate bone. Where the available bone supports two or four implants but not the count required for a stable fixed-arch, removable is the design that actually works without forcing a grafting timeline the patient may not want.
- Cost. An implant-supported denture is typically less expensive than a fixed full-arch: fewer implants, simpler prosthetic, less lab work. For patients where cost is the deciding factor, this is an honest answer rather than a lesser-than version of fixed.
- Preference. Some patients want to be able to take their teeth out at night. That’s a valid preference, not a clinical compromise.
We’ll tell you which fits your case at the consultation. If fixed is right, we’ll say so; if removable is right, same. See full-arch rehabilitation for the broader picture.
Locator or bar: both stable, different by design.
Locator attachments
Individual stud-shaped attachments threaded into each implant. The denture has corresponding nylon retention inserts that snap down onto the studs. Simple, reliable, easy to clean. The nylon inserts wear over time and are replaced at routine maintenance appointments, typically every 12–24 months, in a 10-minute chairside visit.
Locator designs are the common choice for two-implant lower-jaw dentures and many four-implant upper-jaw cases. They’re cost-effective, well-tolerated, and straightforward to maintain.
Bar retention
A custom-milled or printed metal bar connects the implants across the arch. The denture seats onto the bar with retention clips. The bar design distributes occlusal load more evenly across the implants, provides greater retention than locator attachments, and is more durable on the retention side.
Bar designs make sense for patients who want maximum stability from a removable prosthesis, patients with higher bite force or parafunctional habits, and certain cases where implant angulation requires the bar to correct for non-parallel placement. They are typically more expensive than locator designs and the lab work is more involved, which is part of why we keep the prosthetic team in the building.

Most adults missing a full arch.
Long-time denture wearers tired of adhesive and movement. Adults with a full-arch worth of failing teeth who want the most accessible path to stable replacement. Patients for whom fixed full-arch is contraindicated by hygiene, bone, cost, or preference. We confirm candidacy from the CBCT at the planning appointment. The question is rarely whether you can have implant-supported dentures, it’s how many implants and which attachment design fits your case.
The few patients who aren’t candidates are usually candidates for a different path: All-on-4 with strategic angulation, zygomatic implants for severe upper-jaw loss, or staged grafting before any implants go in. We’ll be honest about which path fits.
What ownership actually looks like.
Daily. Remove the denture at night. Clean it thoroughly outside the mouth: denture brush, denture cleaner, water rinse. Clean the locator attachments or the bar with a soft brush. Brush around the implants in your mouth as you would natural teeth. Re-seat the denture in the morning.
Every 1–2 years. Nylon retention inserts (locator design) or retention clips (bar design) are replaced as part of routine maintenance. A 10–20 minute visit; no anesthesia, no surgery.
Every 5–10 years. The denture body itself may need relining or refurbishment as gum tissue underneath gradually changes shape. The implants and the attachments themselves typically don’t need replacement. They’re designed to last for decades.

What’s included in the quote.
Implant placement (two or four), IV sedation or local anesthesia, the implant-supported denture itself, all lab work, and post-operative follow-up. Full ranges and financing terms are on the cost & financing page.
The decision between this path and a fixed full-arch is best made with the imaging in front of us. Book a consultation and we’ll walk you through both, side-by-side, before recommending one.
