Full Mouth Dental Implants: Who Is a Candidate?

You have lost most or all of your teeth. Or the ones left feel like they are on borrowed time. Dentures slip. Eating is a guessing game. You want something fixed, stable, and built to last. Full mouth dental implants can deliver that, but not every patient qualifies on day one.

Most adults with enough jawbone and stable health are candidates. The treatment places four to six titanium posts per arch into the jawbone. A fixed bridge locks onto those posts and stays in your mouth around the clock. In Ontario, a single arch runs $20,000 to $35,000. Both arches together fall between $40,000 and $70,000.

Dr. Marwan Elaraby, co-owner of Cambridge Centre Dental Care, uses CBCT 3D imaging, PiezoSurgery, and GalvoSurge implant cleaning to plan and place full arch implants in-house. That means fewer outside referrals and a shorter path from scan to surgery for Cambridge patients.

Key takeaways if you are thinking about full mouth implants

• Most adults with stable health and enough jawbone qualify. Bone grafting can help those who fall short.
• Full arch implants in Ontario cost $20,000 to $35,000 per arch. Both arches run $40,000 to $70,000.
• The CDCP does not fund implant bridges. These fall outside the plan’s list of covered services.
• A CBCT 3D scan is the first real step. It shows bone volume, nerve paths, and sinus position before any surgery.
• Cambridge Centre Dental Care offers implant consults seven days a week, with evenings Monday through Thursday.

What are full mouth dental implants?

Full mouth implants replace every tooth in one or both arches. A fixed bridge attaches to four to six titanium posts set into the jawbone. The posts fuse with the bone over three to six months through a process called osseointegration. A 2019 review in the Journal of Clinical Medicine found a 10-year survival rate above 94 percent for full arch treatments.

The bridge stays in place around the clock. You brush and floss it like natural teeth. You do not take it out to clean. It handles steak, apples, and corn on the cob, all the foods that shift or crack a loose denture.

Two main formats exist. An All-on-4 uses four implants per jaw, angled to grip the bone that is already there. An All-on-6 adds two more posts for extra support. Your dentist picks the format based on your bone density and bite load.

Jawbone density, the biggest factor

Jawbone volume is the number one factor in candidacy. When teeth go missing, the bone beneath them shrinks. It stops getting pressure from chewing and slowly thins. The longer the teeth have been gone, the more bone you lose.

A CBCT 3D scan shows exactly how much bone you have. It maps height, width, and density in all three planes. Cambridge Centre Dental Care uses the Dexis OP3D for this scan, done right in the office.

If bone volume is low, grafting can rebuild it. Graft material fills the thin areas and needs four to six months to harden. Some patients with mild to moderate loss can skip grafting with angled implant placement. That is the main idea behind the All-on-4 approach.

How does gum health affect your chances?

Active gum disease stops implant surgery until the infection clears. Bacteria from untreated gum disease can block the post from fusing with the bone, a failure called peri-implantitis.

Your dentist checks pocket depths, bleeding points, and X-rays for bone loss around any teeth still in place. If gum disease shows up, treatment comes first. That adds weeks or months to the timeline, but skipping it puts the whole investment at risk.

Patients who lost their teeth to gum disease can still qualify after treatment brings the tissue under control. Stable gum health is the goal. Active infection is the barrier.

Medical conditions and lifestyle habits

Overall health matters because surgery needs healing. The bone has to accept and grow around the titanium post. Conditions that slow healing raise the risk.

Uncontrolled diabetes is the most common flag. High blood sugar slows wound repair and raises infection risk. Patients with well-managed diabetes, with an A1C under 8 percent per the American Diabetes Association guideline, are generally good candidates.

Smoking is the next concern. Smokers face a higher failure rate because nicotine shrinks blood vessels and limits blood flow to the surgical site. Most implant dentists ask patients to quit at least two weeks before and eight weeks after surgery.

Other conditions to discuss with your dentist: blood thinners, autoimmune disorders, past head and neck radiation, and long-term bisphosphonate use for osteoporosis. None of these is a flat “no.” Each one needs a plan.

What happens if you do not qualify today?

Not qualifying right now does not close the door. The three most common delays are low bone, active gum disease, and a medical condition that needs better control. All three are fixable.

Bone grafting builds volume over four to six months. Gum treatment clears infection and lets tissue heal. Medical adjustments bring sugar, blood pressure, or medication into a safer range for surgery. Many patients who start as a “not yet” complete their implants within a year.

For patients who need teeth sooner, implant-supported snap-on dentures offer a middle step. Two to four implants per arch anchor a removable denture that clips into place. They cost less, $6,000 to $15,000 per arch, and still grip and chew better than a loose denture.
