All-on-X Dental Implants in Portsmouth, NH
If you are missing most or all of your teeth on an upper or lower arch, you may be looking into All-on-X dental implants in Portsmouth, NH as a way to get a fixed, non-removable smile again. At Seacoast Prosthodontics, full-arch treatment is planned by Dr. Randi, who completed formal prosthodontic specialty training after dental school and a general practice residency. We welcome new patients and are happy to get you started with a thorough consultation. Our team is also glad to walk you through your insurance and financing questions before you make any decisions, so you understand your options from the start. This page explains what All-on-X treatment involves, who tends to be a good candidate, and how it compares to a removable implant-supported denture.
Why It Matters Benefits of All-on-X Full-Arch Dental Implants
All-on-X is a type of dental implant treatment that uses four implants, placed at specific angles, to support a full arch of replacement teeth. Because the bridge attaches to the implants and stays in place, it works much more like natural teeth than a removable appliance does. Patients considering this option often value:
-
A stable bite for chewing, without the shifting that can come with a loose or removable denture
-
A fixed bridge that stays in your mouth around the clock, rather than one you take out at night
-
Ongoing support for jawbone health, since implants provide stimulation that a denture resting on the gums does not
-
A more natural feel when eating, speaking, and smiling
Because All-on-X uses fewer implants than some other full-arch approaches, it can also be a practical option for patients who have some bone loss but not enough remaining bone for a higher implant count.
Your Visit What to Expect During All-on-X Treatment
Before any implants are placed, Dr. Randi uses 3D Cone Beam CT scanning and computer-guided implant planning to map out the exact position, angle, and depth for each implant. This planning step reflects the practice's whole-mouth, function-first approach: your bite, jawbone, and remaining teeth are all considered together, rather than looking at one problem area in isolation.
On treatment day, any remaining teeth in the arch are typically removed if needed, four implants are placed at the planned positions, and a bridge is attached. Healing time varies from person to person, since the implants need time to bond with the jawbone before your final, long-term bridge is placed. Dr. Randi will go over a timeline specific to your case, including whether a temporary bridge is used while you heal.
Am I a Candidate for All-on-X Dental Implants?
Good candidates for All-on-X are usually missing most or all of their teeth in an arch, or dealing with failing teeth that will need to come out. You also need enough healthy jawbone to support four implants, along with overall health that allows you to heal well after surgery. If you are only missing one or two teeth, single tooth implants may be a better fit than a full-arch approach. The clearest way to find out if you qualify for All-on-X is a consultation, where Dr. Randi reviews your CT scan, health history, and goals.
Your Options All-on-X vs. Implant-Supported Dentures: Comparing Full-Arch Options
Both options replace a full arch of teeth using dental implants, but they differ in how they attach, how many implants they use, and how you care for them day to day. Here is how All-on-X compares to implant-supported dentures:
| Feature | All-on-X | Implant-Supported Dentures |
|---|---|---|
| Attachment | Fixed bridge, does not come out | Removable, snaps onto implants for cleaning |
| Number of implants | Typically 4 per arch | Often 2 to 4, depending on design |
| Daily care | Brush and floss like natural teeth | Remove nightly for cleaning and soaking |
| Cost range | Generally higher, due to the fixed bridge design | Generally lower, with fewer components |
| Candidacy | Needs enough bone at 4 implant sites | May suit patients with more bone loss or different budget needs |
If a fixed, non-removable bridge that feels close to natural teeth matters most to you, All-on-X is worth discussing further. If a removable option that is easier to clean, and that may fit a different budget, sounds like a better match, implant-supported dentures could make more sense. Dr. Randi can walk you through both during a consultation and help you weigh the tradeoffs.
Good To Know
Frequently Asked Questions About All-on-X in Portsmouth
What happens if I wait to replace missing teeth?
Waiting to replace missing teeth can lead to more bone loss in the jaw, shifting of remaining teeth, and changes to your bite over time. The longer an arch goes without teeth or a stable replacement, the more bone volume you may lose, which can affect future implant options. Talking with Dr. Randi sooner rather than later helps keep more options open.
How much do All-on-X implants cost in NH?
All-on-X cost varies based on your specific case, including how many teeth need extraction, whether bone grafting is needed, and the materials used for your final bridge. Because pricing depends on individual treatment planning, the most accurate estimate comes from a consultation and CT scan review. Our team can also help answer insurance and financing questions once you have a treatment plan.
How long does All-on-X treatment take from start to finish?
Timelines vary from patient to patient, depending on healing time, whether extractions are needed, and how your body responds after implant placement. Some patients wear a temporary bridge while the implants bond with the jawbone before the final bridge is placed. Dr. Randi will give you a timeline specific to your treatment plan during your consultation.
