All-on-X Full-Arch Implants

All-on-X anchors a full fixed arch of teeth on four or more implants, offering stability, chewing power and appearance that removable dentures cannot match.

Watch the short explainer, then read on for what the procedure involves.

All-on-X describes a full arch of fixed teeth supported by four, five or six implants — the “X” simply stands for the number used in your case. The bridge is attached to the implants and is not removable by the patient, which makes it function far more like natural teeth than a denture.

Who it suits

It is designed for patients who have lost all the teeth in an arch, or whose remaining teeth are failing and not worth saving. It is also a common solution for long-term denture wearers who struggle with a loose lower denture, since the lower jaw offers the least suction and is where conventional dentures perform worst.

Because the bridge is anchored to implants rather than resting on the gum, biting force improves substantially compared with a denture, and there is no palatal coverage in the upper jaw — so taste and the sensation of hot and cold are preserved.

What to expect

Planning involves a 3D scan, photographs and records of your bite and facial proportions. Any remaining hopeless teeth are removed at the surgical visit, the implants are placed — often angled toward the front of the jaw where bone is densest, which can avoid the need for grafting — and a fixed temporary bridge is usually attached the same day.

You then heal for around three to six months on the temporary bridge before the definitive one is made and fitted.

Living with a fixed arch

A soft diet is essential during integration. Once the final bridge is fitted, most patients eat a normal range of foods.

Cleaning is different from natural teeth and matters enormously. There is a small space beneath the bridge that must be cleaned daily with superfloss, an interdental brush or a water flosser — this is the area where problems begin. Regular professional maintenance is part of the treatment, not optional: the bridge is periodically removed by your dentist at Parkway Dental for thorough cleaning and inspection. Smoking markedly increases the risk of implant failure.

Common questions

Can I take it out?

No. The bridge is fixed to the implants and only your dentist can remove it, which is done periodically for maintenance. That is precisely what makes it feel more like natural teeth than a denture.

Do I really get teeth the same day?

In most cases a fixed temporary bridge is attached on the day of surgery. It is not the final bridge — that is made after several months of healing.

How do I clean underneath it?

Daily, using superfloss, interdental brushes or a water flosser to clear the space between the bridge and the gum. Neglecting this is the most common cause of long-term problems.

Will I need bone grafting?

Often not. Angling implants toward areas of denser bone at the front of the jaw is one of the main advantages of this technique. Your 3D scan will confirm.
