Implant-Supported Dentures in Portsmouth, NH
Implant-supported dentures in Portsmouth, NH combine a full or partial denture with a small set of dental implants that hold it firmly in place. Instead of relying only on suction or adhesive, the denture clips onto the implants, so it stays secure while you eat, talk, and smile. This option is often considered by patients who are missing most or all of their teeth in an arch and want more stability than a traditional removable denture provides. New patients are welcome at Seacoast Prosthodontics, and our team is happy to talk through your insurance and financing options so you understand your choices before you decide on a treatment plan.
A decision about a full-arch restoration deserves careful planning, which is why cases like this at our practice are handled by Dr. Randi, a prosthodontist with formal specialty training beyond dental school. Dr. Randi earned his dental degree at Columbia University, then completed a General Practice Residency at the Brooklyn VA and a Prosthodontics Residency at the Manhattan VA. That background, paired with CT-guided digital imaging for implant planning, allows treatment to be mapped out in detail before any implant is placed. This level of specialist-trained planning is part of what sets a prosthodontic practice apart from a general dentist's office for complex cases.

Why It Matters Benefits & Value of Implant-Supported Dentures
Implant-supported dentures are designed to offer several everyday advantages over a traditional removable denture:
-
Stronger bite force. Implants transfer chewing pressure to the jawbone, which can make eating a wider range of foods more comfortable.
-
Less slipping. The denture locks onto the implants, so it is less likely to shift when you talk, laugh, or eat.
-
Support for jawbone health. Implants help stimulate the bone in a way a traditional denture cannot, which may help slow the bone loss that follows tooth loss.
-
More comfort. With implants providing support, some dentures can be designed with less bulk, which may reduce pressure on the gums or free up the roof of the mouth.
-
Renewed confidence. A denture that stays in place can make it easier to eat, speak, and smile without worrying about it moving.
Your Visit What to Expect: Treatment Process & Your Options
Treatment usually starts with a consultation and a CT scan, so Dr. Randi can evaluate your jawbone and plan implant placement with computer-guided precision. Depending on your bone health and goals, implants may be placed in a single visit or across a series of appointments. Most patients need a healing period after implant placement before the final denture is attached, though a temporary denture can sometimes be worn during healing. Once the implants have joined with the bone, we take digital impressions and fit your final implant-supported denture, then check your bite and comfort at follow-up visits.
| Feature | Implant-Supported Dentures | All-on-X |
|---|---|---|
| Fixed vs. removable | Removable, snaps on and off for cleaning | Fixed in place, not removed by the patient |
| Cost range | Generally a lower upfront cost | Generally a higher upfront cost |
| Implant count | Often 2 to 4 implants per arch | Typically 4 implants per arch |
| Daily care | Removed nightly for cleaning, similar to a denture | Cleaned in place, similar to natural teeth |
| Revision/reline needs | May need periodic relines or adjustments over time | Generally requires less frequent relining |
Implant-supported dentures and All-on-X both use dental implants to support a full arch of teeth, but they work differently day to day. Neither approach is automatically better than the other. The right choice depends on your jawbone volume, budget, and how you would like to care for your teeth day to day. Dr. Randi will review both options with you at your consultation.
What Happens If You Delay Treatment
Waiting to replace missing teeth can affect more than the way your smile looks. Without teeth or implants to stimulate it, the jawbone in that area can slowly shrink over time, which may make implant placement more complicated later on. A loose or ill-fitting denture can also make it harder to chew certain foods, which may affect nutrition over time. Changes in bite can place extra strain on remaining teeth and jaw joints as well. There's no need to rush a decision, but understanding these changes can help you decide when the time feels right for you.

Good To Know
Frequently Asked Questions
Am I a candidate for implant-supported dentures?
You may be a candidate if you are missing most or all of your teeth in an arch and have enough jawbone to support implants. Good gum health and no untreated bone loss also help your candidacy. If you are only missing one tooth, single tooth implants may be a better fit than a full denture. A consultation and CT scan with Dr. Randi will confirm whether implant-supported dentures are right for you.
How many implants are needed to support a denture?
Most implant-supported dentures use between two and four implants per arch, depending on your jawbone and the type of denture chosen. All-on-X, a related full-arch option, typically uses four implants placed at specific angles. Dr. Randi determines the exact number you need using CT-guided treatment planning.
How long do implant-supported dentures last?
With good care, the implants themselves are designed to last many years, often decades. The denture attached to the implants may need periodic adjustment, relining, or eventual replacement due to normal wear. Regular checkups help catch wear early, before it becomes a bigger issue.
What is the cost of implant-supported dentures?
The cost of implant-supported dentures depends on how many implants you need, the condition of your jawbone, and whether any preparatory treatment is needed first. Because pricing is different for every case, we recommend a consultation for an accurate estimate. Our team can also review your insurance and financing options to help you understand what may be covered.
