When you are missing most or all of your teeth, every meal, conversation, and photo becomes a reminder of what you no longer have. Removable dentures offer a visible solution, but they shift against the gums with every bite, rely on adhesives to stay in place, and allow the underlying jawbone to continue shrinking, which means the fit gets worse over time rather than better. All-on-4 dental implants in Charlotte replace both the teeth and the root structure beneath them, giving you a fixed, bone-supported result that functions the way a natural smile does.
Harmony Dental Implants and Oral Surgery is one of the few Charlotte-area practices where a board-certified oral and maxillofacial surgeon performs every stage of your All-on-4 care in-house, from the CBCT imaging and treatment planning through the surgical placement and final restoration. Dr. Riddhi Patel earned her DMD from the University of Pennsylvania, completed her surgical residency at Mount Sinai Hospital in New York, and is board-certified by the American Board of Oral and Maxillofacial Surgery. She is a member of the American Association of Oral and Maxillofacial Surgeons, the American College of Oral and Maxillofacial Surgeons, and both the North Carolina and South Carolina Dental Societies. For all patients pursuing dental implants at our Charlotte practice, we warranty every implant for five years and will replace it at no cost if a failure occurs.
All-on-4 is a full-arch replacement system that uses four strategically placed titanium implants to support a complete set of upper or lower teeth. Two implants are positioned vertically at the front of the arch, and two are angled at the rear to maximize available bone contact, which allows the system to work even when some bone loss has already occurred. A temporary fixed arch is attached the same day as surgery, so most patients leave our Charlotte office with functional teeth before their permanent restoration is placed months later.
Long-term clinical data backs how dependable this approach is. A study published through the National Institutes of Health documented All-on-4 cumulative implant survival rates of 96.2% over ten years, with the maxillary arch showing 95.7% survival at 13 years. For patients looking for a permanent solution rather than a temporary fix, All-on-4 is one of the most extensively studied full-arch options available.
The core difference between All-on-4 and conventional dentures is what happens beneath the gum line. Dentures sit on top of the gums and do nothing to stop the bone from resorbing, which is why the fit deteriorates year after year and requires repeated relines. All-on-4 anchors into the bone itself, which stimulates it and keeps the restoration stable without adhesives.
| All-on-4 Implants | Traditional Dentures | |
|---|---|---|
| Fixed or Removable | Fixed — never removed | Removable — taken out nightly |
| Bone Preservation | Preserves bone by replacing the root | Bone resorbs over time without a root |
| Stability | Secure as natural teeth — no shifting | Can slip when eating or speaking |
| Adhesives Required | None | Often needed for daily security |
| Maintenance | Brushed like natural teeth | Soaking, special cleaners, periodic relining |
Most healthy adults who are missing all or most of their teeth on one or both arches qualify for All-on-4. The angled placement of the posterior implants allows the system to work with less bone than conventional implant protocols require, which opens the door for patients who have been turned away elsewhere due to bone loss. Dr. Patel evaluates every case with CBCT imaging before making any recommendation. Common candidacy factors include the following:
When bone loss is more significant, preparatory procedures such as bone grafting may be needed first. Patients with severe upper jaw bone loss may also be candidates for zygomatic implants as an alternative full-arch path. Imaging determines the right direction for every case.
Treatment unfolds across several appointments, and we walk you through each phase clearly before anything is scheduled. The order and timing vary by case, but the path follows the same structure for most patients.
Most patients return to light daily activities within a few days of surgery. Our team stays available throughout recovery and at every follow-up appointment to confirm healing is on track. For a full picture of what All-on-4 involves financially before you schedule, we review All-on-4 cost and financing during your first consultation.

All-on-4 is the most common full-arch path, but it is not the only one. Depending on your anatomy, bone volume, and goals, Dr. Patel may discuss one of the following approaches during your consultation. Every plan begins with imaging, not assumptions.
Dr. Patel performs all of these procedures in-house at our Charlotte location, which means your evaluation, surgery, and follow-up care all happen with the same surgical team from start to finish.

For patients pursuing All-on-4, we offer 0% financing for up to 24 months through Cherry, which carries one of the highest approval rates of any dental financing program, along with Proceed Finance and additional options. We walk through your specific coverage and estimated out-of-pocket costs at your first consultation so there are no surprises.
