🦷 How Many Teeth Can Be Replaced with Just 4 Implants?

Many patients are surprised to learn that an entire arch of missing teeth can often be replaced using only four dental implants.

This advanced solution is known as the All-on-4® technique, and it has transformed full-mouth rehabilitation.

💡 What is the All-on-4® concept?

The All-on-4® approach uses four strategically placed implants to support a fixed full-arch prosthesis (bridge).

The All-on-4® technique is an advanced dental implant solution that restores a full arch of teeth using only four implants. These implants are strategically placed—two vertically in the front and two angled in the back—to maximize contact with available bone and avoid the need for bone grafting. This innovative method supports a fixed, natural-looking prosthesis (bridge), providing immediate function, improved stability, and enhanced aesthetics. Ideal for patients with missing or failing teeth, the All-on-4® approach offers a faster, cost-effective alternative to traditional full-mouth implant procedures, often enabling same-day restoration with long-lasting results.

This design allows for a stable, secure replacement of all teeth in one jaw, typically 10–14 teeth per arch.

✅ Advantages of teeth replaced by just 4 implants

• Fewer implants needed — Less invasive and more cost-effective.
• Immediate function — In many cases, a temporary fixed bridge can be placed on the same day.
• No need for bone grafting (in many cases) — Thanks to the angled placement, patients with bone loss can often avoid additional surgeries.
• Natural look and function — Feels and performs like natural teeth.

⚠️ Who is a candidate for this treatment?

Candidates for the All-on-4® treatment are typically individuals who have lost most or all of their teeth in one or both arches, or those with severely damaged or decayed teeth beyond repair. It is ideal for patients who want a permanent, fixed solution instead of removable dentures. Even those with low bone density may qualify, thanks to the strategic angulation of the implants, often avoiding the need for bone grafts. Good overall health, healthy gums, and a commitment to proper oral hygiene are important for long-term success. A thorough evaluation by a dental implant specialist is essential to confirm candidacy.
